Some videos work perfectly fine, however for some videos audio lags behind the video. The same video file perfectly works in Chromium as a control test. Example file is MP4, inside was initially h264 video with AAC audio, for test I re-encoded video to be svt-AV1 with AAC / flac as well - no difference, audio still lags behind. Local players (mpv) and Chromium works perfectly. No plugins which can affect it - for testing disabled them all. I really try hard to like Firefox but this thing is a real bummer. Any ideas what can be causing? P.S. I tested both firefox compiled from source and binary package provided by my distro. Linux system if that matters.

I've noticed that Youtube videos on Firefox are far more washed out when compared to Google Chrome. HDR is enabled on my Monitor and in Windows 11; however, the issue is present for standard SDR videos as well. Any idea what is going on here?

Firefox Autoplay videos not working

I'm exploring Steam Deck desktop mode more and I'm running into issues with Firefox not rendering some videos on my personal website. I wasn't sure if it was a Steam Deck, KDE Plasma, Firefox, or an issue with something else, so I tested the same website with Vivaldi and the video played without any issues. This makes me feel like it's probably Firefox, but not totally sure yet.

I've already tried adjusting the autoplay media permissions for the website from the default to "Allow Audio and Video" in case that was doing something. I've also tested in Troubleshoot mode to see if the one extension I have installed was causing any issues and that didn't change anything either. Any other ideas I can try? Or, is there some way to determine if this needs a bug fix/there's nothing I can do on my end?

While watching netflix, I randomly get error code F7361-1253 which prevents the video from playing. Can happen at any random time while watching. I have had firefox for years and have only got this issue in the past few months. It does not happen on other browsers like chrome.

I have tried disabling all extensions and troubleshoot mode, doesn't fix it. I didn't change any firefox settings since this started happening. DRM is enabled, widevine is the latest version, so is firefox, fully updated. I am using Windows 11 Home, 10.0.22631 Build 22631

These are the warnings I got in the console as soon as the netflix error pops up:


Cannot play media. No decoders for requested formats: audio/mp4; codecs="mp4a.40.42" 81036307

I have ffmpeg on my system and haven't touched it in a while.
