I would suggest to go with the onTextData approach, it seems most clean
and reliable and you would be able to extend it with anything you'd
want.

If I remember the code correctly, on the GStreamer side this would have
to be handled only in flvdemux / flvmux.

How about using H264 custom SEI for this? In which case you wouldnt have to worry about which muxer/demuxer you are using. Also, libav should support extraction of this Custom SEI

You should perhaps modify h264parse to do that. or if you are using x264, there must be a way to insert custom SEI through the APi itself. Worth exploring that
