Hi. I need guidance. There are two options below. There may be more that I don't know about.
1: Does anyone know of a tool to move misplaced GOP headers, and thereby close the GOPs? The video is Shoah [1985], an 8 1/2 hour, 4-part documentary covering the Nazi mass murder of European Jews during WWII. Whoever edited the source (splicing) falsely turned almost all the GOPs into open GOPs. In most cases, the GOPs are 2 frames ahead of the actual keyframes. They don't decode properly of course. I think they can be fixed only by editing the source's PES extension headers, but hopefully I'm wrong. I assume FFmpeg can't do that kind of job. 2: There may be an alternative to fixing the headers. I think that if the PES extension headers are simply removed, the frames may decode well enough for me to recode them with -start_at_zero -copyts and then synchronize audio: -itsoffset -itsscale, if necessary. I'd be very grateful for knowledgeable guidance, please. Mark. _______________________________________________ ffmpeg-user mailing list -- [email protected] To unsubscribe send an email to [email protected]
