Is there something similar to DivFix?
http://www.divx-digest.com/software/divfix.html

I had two faulty RAM memory modules last year when I was encoding some files into H264 (X264) format in a MP4/MKV container. I would like to find if there are any frame errors in the files, DivFix would report something like this (for AVI files):
Corrupted data detected at frame 72105 (00:48:04)
Error offset: 488477482 ($1D1D932A)


Thank you.

Should I assume there is no way you could detect the corrupt frames in such files?

You should assume that none of the 139 readers of this thread have an aswer to your question.

I don't know DivxFix, have any corrupted mp4 file that I'm aware of. But if I did I would try avinaptics to see what it reports.

try playing the file in mplayer and see if it reports any visual or textual errors

Hi Jeffy,

I would suggest to demupltiplex the raw h.264 stream, load it into DGAVCIndex and then do a "save project". During the creation process of the index file, at least the h.264 stream headers are decoded frame by frame by libavcodec, and if there are errors in the stream they should / will be reported.
