Description
The concat filter cause ffmpeg frozen.
prepare any mp4 video , rename it to 1.mp4. then copy it to 2.mp4.
finally execute following command to join the two videos
ffmpeg -f lavfi -i "movie=1.mp4, scale=512:288 [v1] ; amovie=1.mp4 [a1] ;movie=2.mp4, scale=512:288 [v2] ; amovie=2.mp4 [a2] ;[v1] [v2] concat [out0] ; [a1] [a2] concat=v=0:a=1 [out1]" join.avi
ffmpeg begin to encoding successfully , but frozen at 50% .
I used the ffmpeg 20120810 windows build from
http://ffmpeg.zeranoe.com/builds/win32/static/ffmpeg-20120810-git-633b90c-win32-static.7z
I investigate the code and found the frozen caused by av_read_frame , the call will be blocked at 50% position.

Please close this ticket , it seems the bug has already been fixed , I just test it with the latest ffmpeg commandline without frozen problem.

For future tickets: Please always post a (failing) command line together with complete, uncut console output.
Note that it works with
