Is there any way to edit just the metadata of an AVI file, like mkvpropedit does with MKV files ?
20 juillet 2016, par hmj6jmhI am trying to swap the order of 2 audio tracks of an AVI file using
ffmpeg
.ffmpeg -i "infile.avi" -map 0:0 -map 0:2 -map 0:1 -c copy "outfile.avi"
This works but the file is being re-encoded, not copied. It takes much longer than a straight copy to finish and the resulting file is larger than the original.
Is there any way to edit just the metadata of an AVI file, like mkvpropedit does with MKV files ? Command line tool preferred.

How to buffer videojs so preload won't show ?
9 septembre 2015, par toyI’m building video cutting tool using videojs. In order to give the feedback to user right away instead of using ffmpeg to merge the video right away. I just swap the videos instead. However, during the swapping you would see the loading icon when the second video is being loaded. Is there any tricks that would tell videojs to load the video before so when the video plays it would just play right away.

Here’s my code
