The sample aspect ratio is not metadata.

Quoting your other message:

>     Stream #0:0: Video: mpeg2video (Main), yuv420p(tv), 720x576 [SAR 64:45 DAR 16:9], max. 15000 kb/s, SAR 1:1 DAR 5:4, 25 fps, 25 tbr, 1k tbn, 50 tbc (default)

You can observe there are two contradictory aspect ratios. FFmpeg uses the
one from the format, since it is easier to change.
