[FFmpeg-user] rewrite tags in a source's PES headers -- How?

[Mark Filipak]

Hi,

I'm getting some 'wandering' PTSs in the target video.
The target's PTSs are all in the form 'N*1001', but they go up and down as though 'N' goes up and down.

     -bsf:v setts=time_base=1/24000:pts=N*1001:dts=N*1001

The source video is 'NTSC'-soft.

In order to test further, I need a way to change the soft telecine tags in the source VOBs. I've 
spent 2 days trying various things.

Is there a way to rewrite tags in a source's PES headers prior to decoding?

Thanks -- Mark.
