I tried to cut the first part of an .mkv file with: ffmpeg -ss 119 -i input.mkv -codec copy output.mkv
This gives several times something like the following error: [matroska @ 0x561acc0ca700] failed to avoid negative pts -79 in stream 1. Try -avoid_negative_ts 1 as a possible workaround. But as far as I can see the output.mkv is OK. What is happening here? Is it important that I run it again with: -avoid_negative_ts 1 -- Cecil Westerhof Senior Software Engineer LinkedIn: http://www.linkedin.com/in/cecilwesterhof _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
