What I remember from the previous discussions is vague whining about
the brokenness of VLC/the spec, and you saying that there was little
point in considering RTCP-RR because they were too easy to spoof, so
RTSP keep-alive were necessary. Moreover, I remember too that the
RTSP implementation in VLC uses the SDP line "b=RR:0" which disallows
RTCP-RR, making your point moot.
Anyway, it's easy to change the default to disable timeouts, but then
again do you prefer a secure default, or one that accomodates broken
clients? If a user notices unexpected timeouts, it is easy to find the
problem and disable them with the option.
Also, what is your view on RTCP-RR support, before I possibly start
tackling the task?
