Jitsi Meet 1080p

Tired of having to choose between 1080p and reasonable bandwidth consumption? Come meet the Jitsi dev team at the the 12th edition of the RMLL libre software meeting in Strasbourg, July 11-13. The Libre Software Meeting (RMLL) is a free (as in beer and as in speech) and non-commercial conference with talks, workshops stands, and round. Google Hangouts Meet. Google’s oldest functioning communication service, which was meant video.

In this article, I’ll talk about the various servicesand tools that I tried to stream my presentations.I’m going to talk about OBS Studio, why and how I use it.I will also review a bunch of video conferencing and streamingplatforms like Jitsi, Twitch, YouTube, Zoom.

  1. The resolution of the desktop stream depends on the resolution of the screen you are sharing, i.e. If you are sharing your entire 1080p display, this will produce a 1080p desktop track. For higher fps, please make sure you have testing.capScreenshareBitrate=0 along with the desktopSharingFrameRate.max value in your config.js.
  2. Setup: Latest Jitsi Meet self-hosted on DO droplet with dedicated IP. Resolution: 1080, disableSimulcast: true, startAudioOnly: true, Constraints are set to prefer 1080p, but they don’t work on mobile anyway yet. Conditions: Two participants join a call: A) Chrome browser on a MacBook Pro connected via 801.11ac, standing just next to the access point. This client doesn’t send any video.

This section should be relevant regardless of youroperating system(i.e. applicable to Linux, Mac, or Windows),while part 4 will dive into everything specific to Linux.For context, please check part 1!

OBS Studio

When I started to look at what people where using to stream(whether it’s games, educational content, whatever), I sawOBS Studio coming up a lot. OBS stands for Open BroadcasterSoftware, and that’s exactly what it is.

I imagine that when you make a live TV show, you have possiblymultiple cameras, mics, and a kind of mixer that lets youpick which camera you want to show at a given time; perhapsshow multiple things at the same time (“picture-in-picture”),or add banners, titles, effects, and so on. OBS does exactlythat, entirely in software.

You can arrange multiple “sources” (cameras, images, pre-recordedvideos, text…) into “scenes”. Then you can switch between scenesjust by pushing a button. If that sounds confusing, you can checkthe video of my talk, Troubleshooting Troublesome Pods, for an example.(Keep in mind that this was one of my first talks using OBS, and Iwas still getting used to it, working on the transitions, streamingquality, etc.)

Why OBS

So, why would someone want to use something like that, insteadof just sharing their webcam and screen?

I’m going to give you a very personal answer. You’re welcome todisagree (strongly) with it.

It’s very difficult to keep an audience engaged, especially througha video. That’s why TED Talks are only 18 minutes, and that durationisn’t random, it was determined by science. My technical workshopsand training courses are way, way longer than that. Over the years,I learned (consciously or not) a lot of techniques to be as engagingas possible and keep my students interested. Many of these techniquesdo not work for video content. For instance, walking on the stage,pointing things (physically, with my arms and hands) on the screen.Projecting my voice to different parts of the room. The overall bodylanguage.

I want my training sessions to be successful, and that means keepingpeople interested. And it’s not just their responsibility, but also mine.Some folks can keep their attention to a screen share.I can do it maybe 10 minutes, but certainly not for hours.This means deploying many new tricks and techniques. Dynamic videocontent is one of them. It’s obviously not the only one;and it doesn’t work the same way for everyone.

In my case, that means that I want to be able to switch betweenmultiple cameras: one showing the upper half of my body (I presentstanding), typically when addressing the audience and showing slides;and the other one showing just my head, when running demos.So I need a way to efficiently put these things together and switchbetween views. That’s OBS.

OBS workflow overview

OBS works on Linux, Mac, and Windows, and the interface is virtuallythe same on all three platforms. You can use it with your webcam(or webcams, if you have multiple ones), mics. You can share yourscreen (or individual windows) with it. It supports live videoeffects (like chroma key or “green screen”).

When using OBS, you define one or multiple “scenes” (I will tell youthe ones I use a bit later) and then you can output your video+audiofeed in two ways:

  • by sending it over RTMP, a protocol very popular with virtuallyall streaming services including Twitch, Youtube, etc.;
  • by recording it to a local file.

As you can see, this doesn’t include familiar stuff like Skype, Zoom, etc.,but there are ways to make it work, including:

  • showing the OBS preview (your live video) on a screen and sharingthat screen,
  • using a virtual webcam plugin for OBS.

The first option works great if you have an extra monitor (it could bea virtual one if you know how to set that up), but will typically usea lot of CPU resources and may not always give you the best results(more on that later).

The second option should make OBS work with any system that can useany webcam. The “virtual webcam” setup will depend on your platforms(it works differently on Linux, Mac, Windows).

My OBS scenes

I continuously tweak and iterate on this, but at the moment, I am using:

  • pre-roll,
  • slides with camera,
  • slides witout camera,
  • fullscreen with camera,
  • fullscreen without camera,
  • break.

Pre-roll and break show a video in a loop, with a big countdownindicating when we will start (for the pre-roll) or when we willresume (for the break).

This is now the “slides with camera” scene:

I use that one when I don’t necessarily need to full resolutionof the screen, and I want my body language to be visible.This is great for slides and diagrams, for instance.(My slides use very big text, so it’s generally not an issueif they only take a part of the screen.)

As you can see, that scene also shows important links. This isuseful, because when people join, they connect to the video stream,but they don’t always have access to the other links (slides, chatroom, etc.) so I found that it was helpful to have these linkson screen regularly.

I have a similar scene without the camera, which I rarely use.

This is now the “fullscreen with camera” scene:

This is great when showing a text mode terminal, web browser,or anything where I need the full resolution of my screen andthe full “real estate” of the stream; but I keep my head ina corner. And there is the same scene, without my head - becausesometimes there is something important in that part of the screen.

I’m using a “mask” effect on that camera (the hexagon shapeon the example above). It’s a tiny little detail,but it’s more pleasant to the eye, and when I show my slidesusing that scene, the slide number is in the top right corner.The mask lets the slide number show up .

Green screens

You might wonder why I’m not using a green screen. I do have agreen screen, but as soon as you try to use multiple angles, itgets tricky to have the green screen as a consistent backdropagainst all possible angles.

I personally think that it’s better to have multiple angles,rather than the transparent background effect that the greenscreen offers

Countdowns

OBS lets you show text either as a “constant” (you define thetext once for all) or by pulling it from a file. In that case,it will periodically re-read that file and update the text.I have a Python script that runs in a loop and continuouslyupdates a text file with the countdown, and then I set OBSto show that text file in the countdown scenes.

Switching scenes

You can switch scenes by clicking in the OBS interface,or with keyboard shortcuts. I am using a Stream Deckthat sits next to my sceen, and gives me buttons for eachscene. The Stream Deck also has button to “start a five minutesbreak” as well as adding/subtracting one minute from the breaktime (so that I can adjust the break duration in a pinch).

Studio mode

OBS also has a “studio mode” that lets you show a scene whileyou edit another one. This is great to prepare a “next shot”backstage, and then activate it. This sounds amazing to achievesomething even more dynamic, but I imagine that it requiresat least two persons: one in front of the camera, another onebehind (or rather, in front of the OBS interface, with theirattention fully dedicated to it). I haven’t used it yet.

Quirks

I’m pretty happy about OBS, but there are also some downsides.

I’m going to list some of them here. That way, if one of themis a dealbreaker for you, you will know!

Out of the box, OBS can only stream over RTMP. As said above,most streaming sites support that, so that’s great; but if youwant to use it for your video calls, you will have to installan extra plugin or do some hacks, as mentioned above.

It can’t stream to multiple destinations at the same time.Sometimes, this would be very convenient. Again, there arehacks to do that anyway if you need to.

The text features are “OK but not great”. If you are streamingin HD, you will want to use a ridiculously high font size, otherwisethe text will show pixels. Since most fonts are vector-based thesedays, it would be great if it could handle that better. It wouldalso be amazing to be able to change the color of the shadow, orput a backdrop, behind text.

When you get disconnected from the server to which you’re streaming,sometimes it will gracefully recover, but sometimes it will also remainstuck and you will have to quit and restart it.

It doesn’t refer to sources in a consistent way. On Linux, forinstance, it will refer to webcams using their device nodes(something like /dev/video0, /dev/video4, etc.) and when youconnect / disconnect cameras, these numbers can change. The camerasare then all messed up in OBS and you need to reassign them. It’s nota huge deal but I find it mildly annoying with just 2 cameras (3 ifwe count the internal webcam of the laptop, which I’m not using), soI imagine that it could get really obnoxious with lots of cameras.I’ve seen similar complaints from folks using it on a Mac, when theirdevice names change for some reason, they have to re-add them to OBS.

Not really a quirk, but: keep in mind that OBS (and the associatedprotocols and services) is more complex than just firing up Zoom and go.The results can be amazing, but you should be prepared to spend sometime figuring it out. See for yourself if you think it’s worth theinvestment. In particular, if your goal is high quality (like 30 fps,full HD video), you will need some good hardware for encoding,and perhaps learn about video codecs and tuning. This is a wholeother can of worms.

Broadcasting our content

Now that we’ve talked about OBS, let’s talk about how weget that precious video and audio content to our viewers.

Video calls vs streaming

First, let’s start with some general considerations.

From both a practical and technical standpoint, there aretwo kinds of systems: video calls, and streaming.

Video calls are real time (or almost real time, with typicallyless than half a second of delay, which is imperceptible, exceptin some specific scenarios, for instance if you try to performlive music with other people).There can be multiple participants sending audio or video at the same time,meaning that it’s possible to interact directly with the presenter.Most platforms accommodate dozens of viewers, some of them caneven do hundreds.

Streaming is generally one person (or a very small group) sendingto a larger audience.Since audio and video flows in one direction only, interaction requiresa separate channel, like a live text chat or separate Q&A app.Most streaming platforms can accommodate thousandsof viewers, and some of them will scale to millions of viewers.This is achieved by using very different protocols and techniques,which come with a higher latency.The “glass to glass delay” (the delay between themoment when you say or show something, and the moment when youraudience hears or sees it) will be a few seconds in the best casescenario, but typically at least 20-30 seconds.The delay is acceptableto address questions as they come, but makes it harder to doquick “show of hands”, or generally speaking, to ask a questionto the audience and immediately react to it.Finally, streaming tends to offer better quality, because the longerdelay allows to use more efficient encoding and distribution mechanisms,in particular for viewers with slower connections.

Insinctively, a video call is great for a smaller, trusted audience.It allows to re-create the level of interaction that you couldexpect from a traditional in-person meet-up, or a mature classroom.

Streaming is great for a larger audience. It’s also less proneto trolling, heckling, or Zoombombing, since the audience cannotspeak or show themselves. (They can still troll or harass throughthe Q&A or chat platform when there is one, though.) It re-createssomething more similar to a large college amphitheater or conference talk.

If you’re wondering about technical differences: video callstransmit data directly, or with very little intermediaries.They can use a whole range of protocols, including proprietaryand custom ones.On the other hand, streaming is generally done within a web browser,and will often use protocols like HLS or DASH, which break down the contentinto very short segments (a few seconds each) that are then playedback to back by the client. These short segments are normal staticfiles that can be distributed efficiently by a CDN. The whole processintroduces the delay mentioned above, since content now needs tobe transcoded, sliced, pushed to a CDN, buffered on the receiving side.The codecs used are also different, or tuned differently. Somecodecs like the popular H264 can yield higher quality when theycan “look ahead” at incoming frames, but that introduces extra latency.(I’m simplifying a lot of things here, but I hope this helps to understandwhy there is such a dramatic difference between the two approaches.)

My specific requirements

MeetJitsi meet 1080p software

I’m going to give you a list of platforms and services that I tried.Again, this list is by no means exhaustive,and keep in mind that my needs arecertainly very different from yours, so our final choices willcertainly differ.

For reference, here is the use-case that I’m optimizing for.

  • I’m delivering tech trainingthat spans multiple hours, with an audience of 10-100 people.
  • I want people to be able to see my face so that things remainas engaging as possible.
  • I don’t need my face to be in super high resolution.
  • I also want to be able to show my screen, with slides, textterminals, web browser.
  • These things, however, need to be as clean as possible.I am used to zoom text when needed (since I usually presenton a video projector) but blurry text with compression artefactscan be tiresome to read.
  • I want latency to remain small so that I can easily interact withthe audience, ask them questions, react to their answers.
  • I also want to record what I’m doingso that the audience can get a high quality replay.

I do not need to stream to hundreds, or thousands, of people.

I do not need to bring another speaker on the virtual stage(at least not at this point).

YouTube

I haven’t used it directly myself, but I’ve been on multiple shows,live podcasts, etc., that were streamed to YouTube.

I found the latency to be very high and ruled it out for my work.I’m aware that there are settings to supposedly reduce the latency,but I haven’t tried them. I couldn’t find an official documenttelling what would be the typical latency to expect; just individualstatements mentioning anything from 1.5s (which would be great!) to15s (which would be less great).

Google also has the reputation to change how its products workover time, or even discontinue them, so I didn’t want to investmuch time or effort into investigating that. (For instance, thereseems to be a whole thing around a “new” vs “classic” interface,with lots of people asking how to do things that they used to beable to and can’t find how to do anymore. That didn’t bode well.)However, if you have a great experience with YouTube streaming,don’t hesitate to let me know!

Jitsi

Jitsi is an open source video conferencing system. You can deployit on your own servers, and there is also a free option, Jitsi Meet.

During my workshops, I typically switch between three different windows:

  • a web browser showing my slides,
  • a terminal where I run demos,
  • another web brwoser to show the result of these demos.

I thought that I could come up with something with Jitsi, where I wouldshare these three windows + my webcam as 4 separate streams, allowingthe viewers to pick what they wanted to see, and how they wanted to see it,at any given time.

Unfortunately, that didn’t turn out to be practical. Jitsi is fantasticif you want something that works “right here right now”, without havingto install a program: it works in modern web browsers, using the WebRTCframework. However, sharing multiple windows turned out to be veryCPU-intensive, and the quality wasn’t there. It was also inconvenientfor the viewers. Overall, Jitsi is great for what it does (video calls)but not for my use-case.

I still plan on using it to provide live interaction with the studentsto promote a “classroom” kind of atmosphere.

Zoom

At this point, if you’re reading this article but haven’t heard aboutZoom yet, I don’t know under which kind of rock you’ve been living :)

What you may or may not know is that Zoom has two products: Zoom Meetingsand Zoom Webinars. Meetings are video calls (the one that you probablylove or hate), Webinars look more like streaming: you’re the onlyone to present (optionally with co-hosts), there is a tiny bit extralatency (but barely), and the quality seems to be a bit more robustfor the audience.

I discovered another difference between Meetings and Webinars. In Meetings,the audience can interact with you with “non verbal communication cues”.There are buttons to indicate “yes”, “no”, “faster”, “slower”, “I needa break”, that kind of thing. In Webinars, there is only a button toraise hand.

Zoom is great for live video calls. In my experience, it does really wellon slow or unreliable network connections. It also makes it super easyto switch cameras and mics. The screen sharing has a really high quality(more on that later). On the down side, there has been stories in thenews highlighting security concerns. I have opinions about that, butthey are not relevant to the present conversation, so I will leave themaside. And more importantly, it has other issues that make itinferior for my use-case. I’ll talk about them now.

The Zoom chat

Zoom has an integrated chat. It’s convenient if you just need to pastesome information to someone, like an URL or short command to type orerror message. However, it lacks:

  • proper formatting (not just bold and italics, but most importantly,the ability to have monospaced code blocks; or even better, syntaxhighlighting),
  • an easy way to highlight someone,
  • efficient scrolling when there are lots of messages,
  • a better way to notice when a message is addressed to the whole audiencevs just you.

You might think, “whoa, that guy seems picky about their chat room!” andyou wouldn’t be wrong. But as it turns out, I regulary use Gitterwhen delivering workshops and training sessions, and it’s a completelydifferent experience. It addresses all the shortcomings mentioned above,and when I polled training participants, they universally preferred Gitter.I will talk again about it later.

Zoom video codecs and tradeoffs

Zoom does something extremely smart with video codecs. When you share yourwebcam, it uses an average quality video encoding with low latencyand a good frame rate. When you share your screen, it uses a very high qualityvideo encoding, but with a much lower frame rate.

This is great for most people who want to share their screen (with slides,demos, whatever) and show their face as two separate streams. However,as mentioned above, I use OBS Studio to create a single video stream thatalternates between my face, the slides, me next to the slides, etc.

There are at least two ways (that I’m aware of) to send my video to Zoom.

The first method is to use a virtual webcam. OBS sends my fancy videoto the virtual webcam, and it shows up in Zoom (or in any other appfor that matter). Unfortunately, this degradesthe video quality: since Zoom “thinks” that I’m sharing a webcam, it’susing a lower quality video encoding. It’s not really visible when seeingsomeone’s face in a video call, but it becomes very apparent when sharinga terminal or browser.

The second method is to share a screen. The trick that I use is to getOBS to show the video output on a dedicated screen, then use Zoom’s“desktop sharing” on that specific screen. The quality is then crystal-clear,but the frame rate drops significantly, and it becomes very noticeablewhen I am visible on screen.

Zoom little details

When sharing a screen, the Zoom controls are always visible on that screen, and you may or may not be able to hide them. I couldn’t find a wayto completely hide them, so what I do is that I move them off screen.(With a minor annoyance, though: my streaming setup has 3 screens, and forsome reason, I cannot move the Zoom controls to the control screen, which isthe only one hidden from the audience; so instead, I move them to the side,in way that they are 90% off screen, but they still partly show up.)

One last thing: when sharing your desktop with Zoom, it uses a rathersmart privacy feature that will grey out its own windows.For instance, if someone sends you a message through Zoom,and that message shows up on the desktop that is shared with the audience,they won’t see it: they will see a greyed out window instead. I imaginethat this is pretty ueful if someone sends you some private information(like a password) or some profanity, to prevent it from being seen bythe audience.

Discord

It might surprise you to see Discord here. If you haven’t heard aboutDiscord before, some people describe it as “Slack for gamers”. It hasexcellent audio and video sharing capabilities.I’ve seen and heard lots of people dismissing it on the grounds thatit’s “for games”, but it looks promising. I haven’t had theopportunity to use it for a workshop or training yet, but I hopeto try it at some point in the future.

In particular, I wish all the communities and groups out there that aresystematically deploying Slack to provide chat communication wouldconsider something like Discord. It seems to be using an order of magnitudeless resources, and it doesn’t require you to create one separate accountfor each “team” (community, company, group…) that you want to join.But I digress!

Twitch

After watching some folks stream on Twitch, I was impressed by the videoquality (and the fact that for the audience, it just works in a webbrowser), so I decided to try it out.

It is very straightforward to set up. Note that while the audiencedoesn’t need anything special, you need to send your video as a RTMPstream. In practice, that means using something like OBS Studio.(There are tons of other options, of course.)

And indeed, the quality was great. But!

There are a few downsides that you might want to consider.

First, there is no way to make a private stream on Twitch. You cankind of work around this by creating a new user for each stream,with a weird name like validcowgeneratorpotato, and rely on thefact that nobody will find it; but … it’s far from perfect,and while I don’t know if it breaks Twitch’s user agreements,it’s probably not what they have in mind!

More importantly, Twitch will probably not transcode your stream.Transcoding is the action of decoding and re-encoding your stream,generally with different (lower) bitrates and resolutions.

This means that if you stream at e.g. 2500 kb/s, your viewers willall receive a 2500 kb/s stream. This is great if they do havethat capacity, because it will guarantee that they get the bestpossible stream (or at least, the exact quality that you’re sending).But if someone has a slower connection, they’ll be out of luck andthere isn’t anything that you can do about it.

Twitch will offer transcoding if you are a “partner”, and mightoffer it (depending on available capacity) if you are an “affiliate”or even a regular user. (You can find more details on Twitch’saffiliate program page.)

This makes Twitch suitable for public events (and for regular streaming),but not for private workshops or training sessions.

I wish their technology was available by paying them, though, becauseI found it awesome.

Other streaming services

I also tried a few other streaming services. Generally speaking,the quality was great, but the latency was too high for my needs.(I typically had 20-30 seconds of latency.)

These platforms are designed for massive streaming to audiencesof thousands or even millions of viewers, so they’re optimizingalong different angles, of course.

Here are some very brief notes on the ones I tried.

Dailymotion

Super easy to set up once your account gets approved.I really liked the straightforward, “no-nonsense” interface.There isn’t a lot of things to tune or tweak, but at leastI didn’t waste hours trying to fit a square peg in a round hole.

Wowza Streaming Cloud

The setup is relatively easy. However, there arelots of moving parts. It looks like you can customize a lot of things,but when I tried to reduce latency, I quickly got myself in situationswhere I was wondering “is this going to work, or blow up to my face?”

AWS Elemental MediaLive and MediaPackage

The setup was relatively hard, even for someone familiar with boththe AWS ecosystem and the general streaming/ecoding lingo.If you follow the docs and tutorials step by step, it’s easy toget something that works, but as soon as I tried to tweak things,I got myself in corners where it wouldn’t work and give me ratherobscure error messages.

Ant Media Server

I ended up trying Ant Media Server, because it promised “ultra lowlatency, 4k, 60fps streaming for thousands of viewers”. To be clear,I don’t care about 4k and 60fps, but if it can do that, it can certainlydo 1080p at 30fps, and the low latency feature got my attention.The low latency feature is only available for the enterprise edition,but the enterprise edition is available on the AWS and Azuremarketplaces with hourly prices.Since I don’t need this on 24/7, I thought it could be a good idea.

I’m still in the process of validating my whole setup with Ant MediaServer, but (after a lot of tinkering) I’ve seen some pretty good results.Expect an update (or even a complete follow-up article) about it in thefuture.

(At the moment, I’m happy with the low latency streaming, less so withthe adaptive transcoding, but I’ve found ways to work around it byencoding multiple streams at the source. Anyway!)

Virtual classrooms and webinar platforms

There are many products out there. Some of them seemextremely promising, and for many people, are probably bettersolutions than what I’m building.

Unfortunately, I haven’t found any solution yet that wouldlet me stream my own video composition, or have the countdownsthat I use for breaks, for instance. Most of them also can’tdo high quality recording.

I expect this space to evolve a lot these days, since a lot ofactivity is switching to be online during the pandemic, solet me know if you hear about a product that you think I should test!

Everything else

I talked a lot about the video content and how to send it to the audience,but there are other things that matter to me.

Important information should be easily available

I alluded to this earlier in the OBS section. When I delivera training or a workshop, there are more resources than just thevideo feed. There are slides; a chat room; possibly other things.I think it’s important to make sure that the links to these resourcesare super easy to get.

When delivering in-person training, I would often have e.g. theWiFi password and the URL of the slides on a flipchart or whiteboard;that way, if someone shows up late, they can easily get that essentialinformation and catch up.

Same idea here. We’re not likely to be caught in traffic ordelayed by public transit before connecting to a remote classroom;but we could have an unexpected mandatory OS reboot, a kid or otherfamily member that needs immediate assistance, a headset that we thoughtwould be charged but the battery is now empty, etc., so some folks willstill be late, and it’s not their fault, and we need to make it easierfor them. So I try to make sure that people have at least the linkto the stream (or some other landing page) and then I have all therelevant information in the stream.

Chat platforms

The chat rooms that come with Twitch, Zoom, and many other videoconference or streaming platforms generally provide the bare minimumlevel of functionality.

I gave some details earlier about thelimits of the Zoom chat and suggested to useGitter instead.

You might wonder, “why not Slack?” - I think Slack is greatfor some scenarios; specifically the ones where people are expectedto commit a significant amount of time to set it up and use it.But for a short event like a workshop, even a week-long training,I am not a huge fan of Slack. It requires setting up an account,getting a confirmation e-mail, and then you get all these featuresand channels. I prefer something lightweight like Gitter. Gittercan use SSO with GitHub, GitLab or Twitter (if you already have anaccount with these platforms, joining a Gitter chat room will beliterally two clicks). It also uses significantly less resources.

Of course, you do you!

Q&A and polling

Jitsi Meet 1080p App

I want to keep exploring options here. For instance, I intend tosoon test slido to see if it helps to do some quick “hand raising”kind of poll.

Conclusions

After doing my research, I decided to build my own “virtual classroom”by putting together various software bricks and services.

It’s a lot of moving parts (especially as you will see in part 4,where I describe the OBS and streaming setup), and sometimes thatcan be scary; you really don’t want everything to fall apartminutes before starting a course.

However, I really like the flexibility that this is giving me;the ability to pick the tools that fit my teaching style (and thenature of what I’m teaching).

I’d like to emphasize one last time that this is not “the” bestway of doing things; it’s just how I do them right now, and it’slikely to change over time. But I hope that this (which startedas a disorganized collection of notes for my future self) canbe useful for you as well!

Jitsi

In part 4, I will describe how I got OBS (and associatedparaphernalia) to run on Linux. In fact, I even goteverything running in Docker containers, and I’llalso explain why.

Jitsi Meet 1080p Software

Hi guys,

We got some 4K webcams (Avermedia PW513) to use internally on the local network only. Their native res is 3840 x 2160 @ 30fps but they can also do 1080p @ 60fps. I am curious to know if Jitsi Meet supports either of those? I thought it would be a simple case of changing the config to below but all the users are all still limited to [email protected] (most seem to be [email protected] and not 30 which is interesting). Other thing I tried was setting preferH264 to true in case it was an encoding issue but all the clients have CPUs that can encode VP8 and H264 in hardware or software. I dont think the webcam itself encodes to that format.
