Preliminary Checks

• I have read and understood the important section above.
• I have searched existing issues and avoided creating duplicates.
• I am not filing an enhancement request.
• I have checked that this issue cannot be reproduced on Mozilla Firefox.
• I have checked that this issue can be reproduced once I removed all my Mods and Custom CSS.

What happened?

Youtube Live Streams Are Not Working After The Update 1.16.3b On Arch Linux.
Normal Videos Or Even Shorts Work Fine.

Expected behavior

It Should Be Able To Play All Youtube Live Stream

Actual behavior

Youtube Live Streams Are Not Working

Steps to reproduce

Just load any live stream on youtube

Screenshots and videos

Version

1.16.3b

What platform are you seeing the problem on?

Linux (Tarball)

What component is this issue related to?

Media Controler

Relevant log output if applicable

[Propheticus]

Can you check if you have ffmpeg version 7 installed? Version 8 does not work (edit:) for all / has been mentioned as cause of issues on some distros.
Alternatively try the Flatpak, it comes with its own ffmpeg.

[ostuxcat]

Yep ffmpeg 8.0 is installed. also I don't wanna use flatpak version I'm using tarball

[AamchiCodes]

mine is on 8.0 ffmpeg and zen Version 1.16.3b (tarball installation ) i am having no issues for playing youtube live

[Propheticus]

@ostuxcat any chance you can try version 7?

Also, at the time of the error are there any logs in the console (right-click the page > inspect > console tab) or info in that "learn more" link to help point to the possible cause?
A copy of the info on the about:support page would be handy as well (anonymise your username in paths if needed)

@AamchiCodes Maybe you're on different hardware, distro, drivers.

@ostuxcat those logs about audio/mp4 not being supported do make me believe it's an ffmpeg related issue indeed.
Please try the suggested downgrade to ffmpeg 7

[cg219]

Same here and I am on ffmpeg 8 as well. Not sure if it related but I have a custom program where I used ffmpeg as well that broke once I updated to ffmpeg 8 and it was related to how you enable video encoding video filters. Not sure if its related but could be a clue.

I needed to use -init_hw_device vaapi=gpu:/dev/dri/renderD128 -filter_hw_device gpu instead of just -hwaccel vaapi -hwaccel_output_format vaapi

Apparently ffmpeg made it so you need to be explicit with the device you are using (if you are targeting the gpu)

[sekaiwish]

Also having this issue, using ffmpeg 8.0 (can't downgrade due to dependencies)

H264 content I've found is mostly old (8+ years old?) YouTube videos and all of Twitch.TV being affected.
