[FFmpeg-user] -bsf hevc_metadata

[Phoney at neo.rr.com]

Gyan,

Your good suggestion didn't work.

Was:
 Stream #0:0[0x1](und): Video: hevc (Main) (hvc1 / 0x31637668),
yuv420p(tv, bt470bg), 720x576 [SAR 1:1 DAR 5:4], 3913 kb/s, 50 fps, 50
tbr, 90k tbn (default)

That's SAR=1, DAR=1.25.

Now:
 Stream #0:0[0x1](und): Video: hevc (Main) (hvc1 / 0x31637668),
yuv420p(tv, bt470bg), 720x576 [SAR 64:45 DAR 16:9], 3913 kb/s, SAR 1:1
DAR 5:4, 50 fps, 50 tbr, 90k tbn (default)

I've never seen an ffprobe output like that! What is the video now?
"[SAR 64:45 DAR 16:9]"? Or "SAR 1:1 DAR 5:4"?
MPV plays it like it's SAR=1 DAR=1.25.

By the way, The command needed '-codec copy' so it is now this:
E:>ffmpeg -i "SOURCE.mp4" -bsf:v
hevc_metadata=sample_aspect_ratio=64/45 -codec copy "TARGET.mp4"

E:>ffprobe -i "TARGET.mp4"
