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.

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.
