 When use CBS to parse bitstream, it can check invalid synatax/data in the
 bitstream, and report error. How to handle these error is a problem.

 For example, when there are error in SEI, it can break the
 decoding/transcoding process.


 {{{
 ./ffmpeg -bsf:v h264_metadata -i ~/Movies/bean.mp4 -an -f null -

 }}}

 We can ignore some error like invalid data.

 It would be better with the context that the error happens only with SEI,
 so it isn't fatal.
