There is a (big) difference... No -async 1 does not do the trick. What I want to achieve is that if: start_ts = 00:01:00 end_ts = 00:05:00 and input.ts has one or more "holes" for a total of 2 minutes my output video should last 2 minutes and not 4. Using -async = 1 my video still lasts 4 minutes (or 5 if i do not subtract start_ts from end_ts in the -to option), since the -to option is applied to the output video timestamp. -ss has a different behaviour is specified before or after the input file, but -to has not, both if I specify it before -i and after I get a video that is exactly long as end_ts - start_ts, that, if holes are present in the source file is far beyond the "final" timestamp in the input. It seems to work like if -to is a wrapper around "-t duration", rather than a radically different implementation. -- Bye, Gabry _______________________________________________ ffmpeg-user mailing list [email protected] https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
