Description Jean-Yves Avenard [:jya] 2021-11-09 17:08:54 PST 
Seen in bug 231084.

The AVFoundation only supports AVC1 content where the H264 SPS/PPS NAL are defined out of bound and static.

AVC3 allows for SPS/PPS to be in-band and to have the content change mid-stream.

We do not support those files and we can't detect a change of resolution.
