Hi,
I noticed that the RTSPClient class lacks a method for sending RECORD
requests for a whole media session; there's only a method for sending
RECORD requests for individual subsessions. Is this an intentional
omission, or has it just not been needed yet?
I implemented such a method, see the attached patch. This seems to work
fine for me.
