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.

[Live-devel] how to add arbitrary data to an MPEG2 transport stream
Hi Ross, I'm working on a project where I capture a video framebuffer, encode it with NVIDIA encoder and stream it as an elementary h264/265 video stream via live555 mpeg2 transport container. It works fine and it's really fast with negligible latencies. I use an instance of MPEG2TransportStreamFromESSource and add an elementary video stream by using addNewVideoSource. I saw that this is possible for both video and audio elementary streams. Maybe it's a stupid question and I don't want to waste your time but is it possible to add arbitrary data, for instance meta data, as a source to the same container and if what methods/classes should I use?

I now understand the problem, and have just released a new version (2019.08.12) of the code that should fix the problem. (If it still doesn’t work, then please let us know.)

Thanks for the note. Could you please provide (a URL to) a short H.265 Elementary Stream video file that illustrates this problem, so we can use this when testing/reviewing our code?
