My solution works great on linux, it just takes forever and involves more manual work than is optimal :-). My algorithm: 1. One quick encoding to add the six decimal point timestamps to the video as a text overlay. 2. Play that video in mencoder using pause, backup, single step keycodes to sneak up on the exact timestamp I want. Read the screen and copy the timestamps to a file. 3. A script that takes my timestamps and uses -ss and -t options to slowly and painfully start from the beginning of the file, reach the exact timestamp I want and transcode a chunk of video of the right duration. (Trying to speed this up by seeking to a keyframe that preceeds the timestamp never seems to work right, I have to go through the video linearly from the beginning). 4. Then a script that does a "concat" to merge all the chunks into the final video. Any shortcuts I tried never worked. Audio would get out of sync, etc. The only part that consumes my time is copying the timecodes into a file. Everything else is automated and just involves waiting for the computer to finish :-). _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
