ffmpeg | branch: master | James Almer <jamrial at gmail.com> | Mon Jul 23 12:32:47 2018 -0300| [e45ed15594a2553056a577177591fbe55694af44] | committer: James Almer

avcodec/libaomdec: auto insert dump_extra bitstream filter

Some containers, like Matroska, may propagate key frames with no Sequence
Header OBU since it's provided in extradata instead.
With this change, the Sequence Header will be appended to the packet data
before calling aom_codec_decode().
