I've been looking into using libavformat to write mpeg 2 transport
streams with video and MISB (derived from SMPTE) synchronized KLV data
(according to SMPTE RP217-2001.
Looking at the code in mpegtsenc.c it looks like libAvformat isn't setup
to do this yet, am I correct? Does anyone know of any work along these
lines?
If I were to start down this endeavor it looks like the first thing I'd
have to do is define a new code type, something along the lines of
CODEC_ID_SMPTE_KLV
Then I'd need to modify mpegts_write_pmt() to recognize this codec type
and set the stream_type to private data ( 6 ) and then add a
registration descriptor with a format id of "KLVA" (according to the
SMPTE RP 217-2001 section 4.1.1).
I haven't gotten much further than this (actually I don't think there is
much more to be done), but can anyone tell me if I'm on the right track
here?
Thanks,
Matt Schuckmann
