Actually it should work even with file sizes >4gb, since there is fixup
code compensating for an offset wraparound.

The problem is that I have been unable to reproduce the problem so far.
And asking for the corrupt file is a bit out of question I guess. :-)
(Actually, at 60KB/s it would be borderline with 19 hours for a 4GB
file, if you have the upload speed)

Judging from the fact that you could 'repair' your file with -ovc copy
-oac copy, maybe the bug only happens while (re-)encoding?

It would be cool if you could change ODML_CHUNKLEN in
libmpdemux/muxer_avi.c to the commented out value (which should be 16MB
per chunk), reproduce the problem with that and upload the borken file.

He said he hadn't had a byte in three days.
I had a short, so I split it with him.
