Hi Ross,
yes of course it should be standardized and not arbitrary. To be more clearly,
I mean KLV encoded data as defined in the SMPTE standard ST 336.

Probably not with the existing code; it assumes that the streams being
multiplexed into a Transport Stream are audio or video.
If we were to support adding a new type of stream to a Transport Stream, it
would have to be something that?s been standardized (not some arbitrary,
non-standard data).
An alternative would be to stream your H.264/H.265 video data as RTP, rather
than packing it into a Transport Stream. Then, if your metadata is textual
(timed text), then you could also stream it as RTP, using our ?T140TextRTPSink?
class.
