[Live-devel] sending metadata within RTP packet

As you noted, we currently do not support RTP header extensions.

However, depending on the type of ‘metadata’ that you wish to send, it may be possible to use an existing RTP (or new) payload format, to send them in separate RTP packets.

For example, if your metadata is in text form, then you may be able to send it using a “T140TextRTPSink” - i.e., using the RTP payload format defined in RFC 2793.
