Hello, I am trying to inject metadata into a CMAF (fragmented mp4) HLS stream. I am following the example here:
I see how to inject text data using the EmsgFrames object, but how do I inject binary metadata like I can do with ID3 in standard HLS?
There seems to be no documentation on this: EmsgFrames class or the EmsgBuilder() used in the example.
Also, what players support extracting this EMSG metadata?
