 I try to convert video to mp4 with libx264, but ffmpeg hangs up at the end
 of convertion process.

 Nevertheless ffmpeg successfully converts the sample to avi or saves to
 mp4 without convertion (using {{{-vcodec copy}}}).


 How to reproduce:
 {{{
 % ffmpeg -y -i ./hang_up_during_conversion_to_mp4.mp4 -vcodec libx264 -an
 out.mp4
 }}}


 The input video file was saved from ip-camera RTSP stream with ffmpeg
 using {{{-vcodec copy -an -f segment}}}

 I can assert that the problem does not persist at version
 N-67586-g3e1ac10, but persists in N-73635-gfd4c87f and later.

 I can upload the sample video if needed.
