Created attachment 9275655 firefox100_crash.log Hello. Just to add in that this issue at least for my setup (Arch Linux, Firefox 100) is still current.
The previous comment suggest the problem might lie with the decoder but no other software on my machine has problem decoding through vaapi at the moment and the problems began right when RDD sandboxing was made default. Firefox regularly fails and generate loads of crash log on my system each time it comes across a video since ~v98/99. The videos often crash, try to revert to low quality. It's particularly evident on sites like IMGUR. This was working fine before (and it took a long time to get it working) yet it was broken since 2 releases ago and is still in this state... It's quite sad Linux users are the second-class citizens on these features all over again. --- Version: Firefox 100 OS: Arch Linux FFMPEG: 5.0-7 vainfo: VA-API version: 1.14 (libva 2.14.0) --- MOZ_DISABLE_RDD_SANDBOX=1 does not stop this failure on my machine. Nor does MOZ_ENABLE_WAYLAND=1 individually, or combined. --- Cf.
