Add `-copyts` for that. If you want the index of the first decode 
failure, you don't need this patch. Run with `-xerror -v verbose`. 
ist->frames_decoded will be printed for each input stream. Add 1 to 
that. The `time=` value at the end should be the timestamp + duration of 
the last successfully decoded frame, but if you have other streams or 
vsync cfr set, this may not hold.
