This option belongs to libx264, not to FFmpeg.

Try this:

"-x264opts forced-idr"

Thank you, Will. Yes, I did try that:


Try instead this one:

ffmpeg -i <input> -c:v libx264 -forced-idr 1 -an -sn -start_at_zero
-muxdelay 0 <output>

The error msg is

"Error opening input: Invalid data found when processing input" The input isn't recognized. Changing output options won't make any difference. Regards, Gyan

The error message is false, Gyan. There appears to be 3 things going on:
1, '-filter_complex:v select' is getting timestamps that are 12 seconds in 
error,
2, '-filter_complex:a aselect' is interfering with timing during processing by another 24 seconds, even when '-an' is included, and
3, '-copyts -start_at_zero' is failing.

There's something about this Criterion disc that gives FFmpeg indigestion.

I'm investigating and will publish a report.

--Mark.
