Call for testing: OBS-Studio snap


#21

Yep, I made a ffmpeg 4.0 snap (currently classic) that supports nvenc and VA-APPI hardware accelerated decoding and encoding. I also have a prototype that is strictly confined, just waiting on some AppArmor tweaks in snapd so this can be reused.

The ffmpeg snap is 20MB so small enough to bundle in an application snap that requires ffmpeg.

Hi guys,

Sorry for possibly bumping this but I have a question - and I think you guys are the perfect people to ask!

Right now I use Ubuntu 16.04 and I have a script I made that builds FFMpeg 3.4 with NVENC support and builds the latest OBS Studio from the GitHub repo master branch and it works great using NVENC recording in OBS Studio with my GTX 1070. I am wondering - if I use Ubuntu 18.04 with snaps, is it possible for me to just install an FFMpeg snap and an OBS Studio snap and then I can use NVENC recording in OBS Studio with my GTX 1070 - that way, with two snaps, I no longer need to build? Is this possible in Ubuntu 18.04? What about in Ubuntu 16.04 - is this possible?

If this is not currently possible, is it planned for the future?

Thanks!

@ipkpjersi I’ve been working on an ffmpeg 4.0.x snap which can now be confined. The plan is to bundle ffmpeg, that supports accelerated encoding, in the OBS snap.

Hi,

That is awesome news. I am so glad there is a plan for the OBS snap to come with an NVENC-enabled ffmpeg. Thanks so much.

Cheers.

or the description of the output of:

snap info obs-studio

The indicator has no function, no matter how I click it, nothing happens.

Hello

Issue: OBS does not detect my blackmagic card.

System configuration
Ubuntu 18.04
RX 570 open source drivers
uname -a Linux deepcool 4.15.0-45-generic #48-Ubuntu SMP Tue Jan 29 16:28:13 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

No issue with blackmagic software install

When I used obs 21 in the ubuntu repo windows capture would display colours incorrectly. But the blackmagic card would have an option in the obs sources. I forget what it was called So I decided to use obs in the snap repo and that problem was resolved only to be replaced with this one.

How do I have my cake and eat it too?
