Description:
Certain video streams, such as from Twitter, or YouTube, require a decoder for the MIME types video/avc and audio/mp4a-latm, which appears to fail on Firefox 111 when ffmpeg 6.0 (testing) is installed. A temporary workaround I identified appears to be installing the legacy ffmpeg4.4 package. This appears to be resolved on FF 112, which is not merged into the developer edition of the browser.

[Child 9575, MediaDecoderStateMachine #1] WARNING: Decoder=7fc54fb3ad00 Decode error: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005) - Error no decoder found for audio/mp4a-latm: file /build/firefox-developer-edition/src/firefox-111.0/dom/media/MediaDecoderStateMachineBase.cpp:164
