Mpeg file not playing to the end - how to fix corruption

Question

I have a 3.6gb mpeg2 video file the length should be about 25min but the file is corrupt after about 13 minutes and it stops there.

This is the result I got when I tried to correct it:

Z:\Recovery\bin>ffmpeg -i BrokenFile.mpg FixedFile.mpg

Can anyone suggest me how to fix the problem?

Answer 1

Though not a free solution, I have had quite a bit of success upconverting to MP4 using AVS Video Converter; even when the data source was not in perfect shape or completely corrupted. My initial thought on this is that your headers may be corrupted. I am not super-familiar with FFmpeg (save that it is included with the K-Lite Codec Pack!), but I would assume that there is a way to submit the repair sans headers.
Hope this helps!
