Hello everyone, I have a movie .avi and vlc tells me that it has a corrupted index... then I run

Code: Select all

mencoder movie.avi -idx -oac copy -ovc copy -o output.avi


The thing is successful but it is as if it stops halfway through the film, the original file is 1.2 GB and output.avi is 720 MB. Furthermore, the first is encoded in divx while the new one in DX50. Since the exact same thing happens to me using ffmpeg

Code: Select all

ffmpeg-i movie.avi-vcodec copy-acodec copy output.avi


I suppose there is something that escapes me .... Thanks in advance

I'd suggest trying the mencoder (mPlayer) or ffmpeg mailing lists or irc channels http://www.mplayerhq.hu/design7/mailing_lists.html http://ffmpeg.org/contact.html

It is probable that the timestamp data included in the video file is corrupted. You need to instruct ffmpeg to ignore the included timestamp data, and base the encoding on the number of frames/sec - unfortunately I cannot recall the exact switches at this time.

Be aware that these switches in my experience can cause audio resynchronisation unfortunately.
