Where are you receiving this error? All of the videos I use are using the H.264 video codec along with AAC Audio codec. If you're getting this error when transcoding the video, what version of ffmpeg do you have? I have a few different versions that are running on various machines that have done the transcoding.

ffmpeg version 4.2.4
ffmpeg version 5.0-static
