Description Jean-Yves Avenard [:jya] 2021-10-05 03:27:21 PDT 
Seen with bug 231005

MediaPlayerPrivateAVFoundationObjC::paintWithVideoOutput checks that we have a video track before creating an image. However to checks if a video track exists it calls AVAssetTrack* firstEnabledVideoTrack = firstEnabledTrack(safeAVAssetTracksForVisualMedia());


safeAVAssetTracksForVisualMedia queries m_avAsset (a AVURLAsset) for the list of track.

However, with HLS the AVURLAsset doesn't contain any tracks, instead they are found in the AVPlayerItem instead.
