Concatenate mov files

[Serghei]

Summary of the bug:
I have a pipeline who records n video segments . (mov files) .

n = [0 .. 100];

and at this time i'm using ffmpeg for upload live stream to server.
without any codec changes.

Some time one of segments, have swapped streams
and ffmpeg stuck at this segment .

the command for ffmpeg

How to reproduce:

% ffmpeg -re -loglevel debug -report -f concat -i /Users/pc/movies/mylist.txt -c copy -f flv test_bug_concat.flv
ffmpeg version 2.4.2 
built on Oct 24 2014 15:02:40 with Apple LLVM version 6.0 (clang-600.0.54) (based on LLVM 3.5svn)

file mylist.txt contains


file '/Users/pc/movies/0.mov'
duration 00:01:00
...
file '/Users/pc/movies/n.mov'
duration 00:01:00

Patches should be submitted to the ffmpeg-devel mailing list and not this bug tracker.

H.264 inside MP4/MOV is not concatenatable. The concat demuxer can make it so, you need to use the -auto_convert option to enable it.

Replying to Cigaes:

do you tried to concatinate files from attachments whith this command ?

1. i think the problem keeps in streams positions
2. in mov files are same stream positions, concat procces will be successful.

So, i used command ffmpeg -re -loglevel debug -report -y -auto_convert 1 -f concat -i /Users/pc/movies/mylist.txt -c copy -f flv test_bug_concat.flv

the same result. Please see report file ​https://dl.dropboxusercontent.com/u/12422721/ffmpeg-20150102-141828.log
