 I get the above outputted by ffmpeg when encoding from a movie file to
 x264 mp4 aac movie file.

 Sometimes it hangs and the output file keeps growing and growing up to
 500Mb - 700Mb, while it should be just an end file of arround 40Mb-60Mb

 And here it ends it hangs and the 7762_tmp.mp4 file is growing and growing
 till i kill the process.

 And some times it does finish encoding but keeps outputting lines like
 below, but the file is useless, its some wrongly encoded file and does not
 work.
 [mp4 @ 0x9451ac0] Audio timestamp 2147483392 < 2147483521 invalid, cliping

 Any ideas?
