Affected version
0.28.0
Steps to reproduce the bug
Download https://m.youtube.com/watch?v=sRTPiFzXxYQ in either 480p or 720p. You will see that the resulting video file has out of sync video (i.e. the video lags behind the audio). This is most likely a downlaoder muxing issue, related to #12443.
It would be good if someone who has some experience with the MP4 format (standard ISO/IEC 14496-12) could work on this.
