[FFmpeg-devel] [PATCH] libavformat/dashenc: Reduce confusion in par error message

[Chris Miceli]

In ticket #8754 there is discourse surrounding the error
message which is printed upon a mismatched aspect ratio in
derived encodings. This should make it clearer to the user
as to the issues which they are experiencing.
