if you are wondering about the order of execution fo the callbacks, then note
that this is undefined. if you need a timer to execute before another timer
when both become pending at the same time, you need to use priorities.
is there a recipe for that already?
Not really, but using priorities is generally straightforward.
Something that occured to me is that ev_periodic sounds like the right thing
when you want to play somehting at a specific (wallclock) time, but your
problem sounds more like requiring specific inter-packet delays, in which
case an ev_timer would be the right thing (it isn't affected by time jumps).
The problem is that we need both. The rtsp play receives (among the
other things) a time reference about when to start playing, then you are
supposed to send packets at variable delays, I just used an ev_periodic
to do both...
I wrote a bare loop that is more or less what I'd like to archive and I
got the behavior I'd expect so I guess there is something wrong
somewhere else in the code, sorry for the noise =)
While I still don't know whether that's the problem or not, it is vaguely
planned to make timer/perodioc invocation order cosnistent with their
timeout value in some future version.
Sounds nice =)
