Description
Summary of the bug:
I have a 1.1TB ProRes 422 MOV file (a bit more than 24 hours of recording) when I open it with FFmpeg i get the following:
[mov,mp4,m4a,3gp,3g2,mj2 @ 0000000002611ca0] Invalid sample_count=-118755256 [mov,mp4,m4a,3gp,3g2,mj2 @ 0000000002611ca0] error reading header Metadata Error.mov: Invalid data found when processing input
How to reproduce:
% ffmpeg -v error -i input ffmpeg N-87353-g183fd30
The same file works fine in VLC and I get correct metadata from it using MediaInfo.

I created this file using Matrox DSX Utils SDK on Windows.

That patch almost does it. You need to change MOVStts.count on isom.h (sorry I don't know how to generate the diff files myself).
I did the same changes in a local build and it worked.

Please send your patch - made with git format-patch
to the development mailing list, I cannot test here.
