I think this is impossible. The best you can get is an indication. (Which can be way of.) For example I use a script to make videos smaller. In my experience the new file size can be between 1/6 and 1/14 of the file size of the input file. -- 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".
