I do not think so. If there is a bug at work here, it may be to set
codec->width and codec->height from these fields in the container. Do you
know whether there is an authoritative documentation available?

I know you want to fix that, but that precise fix is invalid and causes
worse problems later, i.e. an invalid aspect ratio instead of an unknown

I had just given an example.

As a side note, IIRC, Git commit messages are supposed to be "context: short
summary\n\nLonger summary if necessary." In this particular case, that would
be something like "lavf/rmdec: set sample_aspect_ratio".
