Comment (by Lastique):

 The attached testcase reproduces the problem, it ends with these error
 messages:

 {{{
 [avi @ 0x19c7440] H.264 bitstream malformed, no startcode found, use the
 video bitstream filter 'h264_mp4toannexb' to fix it ('-bsf:v
 h264_mp4toannexb' option with ffmpeg)
 }}}

 and

 {{{
 Failure: Failed to write video frame, error: -1094995529
 }}}

 Note that you can see the encoded video packets if you compile it with
 -DDUMP_PACKETS. You can see then that the first packet contains the 3-byte
 start code.
