[FFmpeg-user] Confusion between PAR and SAR

[Massimo Battistel]

Hello,
maybe this has already been discussed here:

https://ffmpeg.org/trac/ffmpeg/ticket/1776

but I think there is still something wrong.
I think ffmpeg confuses PAR with SAR.
See the output below. The video is an SD 16:9, DAR is correct, but 64:45 is
the PAR.
SAR is 720/576=1.25.

ffmpeg and ffprobe show the same behaviour.
