I never had this problem. Bino uses FFmpeg to read all multimedia input,
so we first have to find out if this is a problem in Bino or in FFmpeg.

Can you try the ffplay video player that comes with FFmpeg?

Can you provide small sample files (one that works, one that does not)?
That would allow us to either debug this on our own or report a bug to
the FFmpeg project.

Apple does not document this codec. Therefore, reverse-engineering is
necessary to support it in FFmpeg. This is a lot of work, and as far as
I know there is currently a lack of manpower and/or money to do this.
