Hello,
we are using a ffmpeg version compatible to 1.08, original version 2.1.1. We have to use this version in caseo of compatibility of a project we overtake from another one. The ffmpeg new API is not working with this project.

However, in our version there is a problem that all video files bigger than 2GB are damaged. It seems the file is written well but finaly it do not generate the information part. All infos in Mediainfo are empty.

Do anybody know this prolem with ffmpeg? MAybe a configuration parameter we miss to set? Or anybody do know a patch? It is not a AVI only issue (we found in google) it happen to alle files special Mp4 and MKW with h264.

I'll presume you are doing this on a NTFS system rather than FAT32.

Have a look at this thread where the same problem occurred and what was done to solve it.

http://forum.videohelp.com/threads/331600-ffmpeg-output-2gb-limit-Is-there-one-ffmpeg-stops-encoding-h264-2gb

Does look like a ffmpeg problem though.

Yes I use NTFS, this was the first thing I checked. But my problem is not that ffmpeg stops, it seems that it do not write the trailer at the end. So no software can read the infos about the content and codecs.

But same here, I do not find any information about this. To make sure some friends made the same encoding on their computers with mkv and als with mp4, they have the same problem. OIt is amazing that those bugs are not published at ffmpeg.

You might need a parameter to tell ffmpeg to use a 64 bit mp4 file container than a 32 bit mp4 container.

32 bit mp4 containers seem to max out at 4 Gb but 64 bit ones are unlimited.  I realize your files have problems at 2 Gb but won't hurt to try.

Afraid I don't know what that parameter setting is.
