Video playback issues on Firefox 110


Recommended Posts

Something annoying I realized today is that I can't play 1080p or higher resolution videos on Youtube with FF 110.0 on my old laptop. They either refuse to play or keep skipping dropping massive number of frames. No problems with all the other Firefox versions (v96 or older) and Opera. Apparently the idiots at Mozilla introduced some new shit with version 104 which most likely is the culprit. I fixed it by setting the following preference to FALSE which was TRUE by default. If anyone else is having the same problem, they might want to experiment with this setting or the ones below it.

media.wmf.dxva.d3d9.amd-pre-uvd4.disabled -> FALSE (Default: TRUE)

Some person on Reddit suggests the following changes as well but they didn't work for me.

media.wmf.zero-copy-nv12-texture          -> FALSE (Default: TRUE)
gfx.direct3d11.reuse-decoder-device       -> FALSE (Default: TRUE)

Note: You need to go to about:config to change these settings and then restart your browser.
