<div>Hi Ross, </div>
<div> </div>
<div>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. </div>

<div>Best regards</div>

<div>> 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.</div>
<div>> 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</div>
<div> </div>
<div>Probably not with the existing code; it assumes that the streams being multiplexed into a Transport Stream are audio or video.</div>
<div> </div>
<div>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).</div>
<div> </div>
<div>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.</div>
