 Summary of the bug:

 When -xerror is used and an error occurs, FFmpeg does not always exit with
 a non-zero exit code, making it difficult for scripts to tell if there was
 an error.

 How to reproduce:

 Any file with errors works, but I deleted random bytes from the beginning
 of a JPEG image to test.

 {{{
 $ ffmpeg -xerror -v error -i brokenfile.jpg -f null -
 [mjpeg @ 0000000002545460] error count: 64
 [mjpeg @ 0000000002545460] error y=1 x=3
 $ echo "$?"
 0
 }}}
