Hi
I needed to be able to use the write_data_type callback when reading data from
the mpegts muxer, to make my application aware of key frames in the data so I
added support. I used the matroska implementation as a reference.
If this is accepted, I will format this as a proper patch after feedback.
Regards
Oliver
