Hi,
In my project where I simulate some kind of push to talk, I need to be able to have no payload in the RTP packets when the PTT is off. I succeeded to do that by removing the payload in a custom transport adapter and the transport_send_rtp callback (but is it the best way to do that?).
Anyway my second need is to change the frequency of RTP packets when I remove the payload (PTT off). For example:
with audio: RTP frame every 20ms
without audio: RTP frame every 200ms
So I was thinking of dynamically changing the ptime of the codec in use, but I don't figure out how to do that (again this may not be the right way to do it, any other suggestion welcome then).
Could anybody give me an hint?
Thanks.
Thibault
