8ce674da87 rtpjitterbuffer: always store lost event in jitterbuffer
Always prepare a lost event in the jitterbuffer, it is to wake up and make the
pushing thread continue. We drop the event when we are not supposed to push lost
events downstream.

9f3345fcc2 rtpjitterbuffer: schedule lost event differently
Schedule the lost event by placing it inside the jitterbuffer with the seqnum
that was lost so that the pushing thread can interleave and push it properly.

39a2ba669d rtpjitterbuffer: use structure to hold packet information
Make the jitterbuffer operate on a structure containing all the packet
information. This avoids mapping the buffer multiple times just to get the RTP
information. It will also make it possible to store other miniobjects such as
events later.

1760817005 rtpjitterbuffer: update expected timer when possible
When we receive a packet and we have some missing packets, we can update their
estimated arrival times based on the timestamp difference.

fdc1ed1680 rtpjitterbuffer: fix order of timeout events
Improve the order of the timeout events, if there are timers with the same
timeout, we want to trigger the lowest seqnum first. For this we need to loop
over the complete array of timers to find the best one before triggering the
timeout.

0b1a7edfea rtpjitterbuffer: send lost event before signaling next buffer
First send the lost event, then update the next_seqnum counter and then
send the signal to the pushing thread that it can retry to push a buffer. This
avoids pushing out buffers before the lost event is pushed.

5dc207948c rtpjitterbuffer: improve flush and shutdown
There is no need to unschedule the timer in flush-start, flush-stop will remove
the timers and unschedule.
Unschedule the current timer before attempting to join the timer thread.

c395bf62dd alpha: use POFFSET instead of OFFSET
Use the more correct POFFSET macro to get the offset of a component in its
plane. The offset macro gives the offset of the component relative to the start
of the frame.

cfefdaebb6 qtmux: handle issues correctly when downstream is not seekable
The streamable property only make sense for fragmented formats.
For regular MP4, when downstream is not seekable we can't rewrite
the headers, so qtmux can only work with fast-start=TRUE, where
the headers are written finishing the file.
For fragmented MP4, when streamable is not seekable and the streamable
property is FALSE, we must enforce streamable=TRUE warning the user
about this change

9ae5082204 qtmux: make "streamable" TRUE as default
The most common use case for fragmented MP4 (Dash and Smooth Streaming)
is producing streamable content (even for VOD). streamable=FALSE would only
be used to generate fragmented MP4 with and index of MOOF's that could
be reproduced without a playlist/manifest

fd6c57cf10 rtpjitterbuffer: keep delay as a separate variable in timer
Keep a separate delay in the timer so that we still know the original timestamp
of the packet that this timer refers to. We can then place the correct
running-time in the Retransmission event.

f2efdf28f5 rtpjitterbuffer: push the lost event from the timer thread
Instead of pushing the lost event from the chain function, schedule a timeout
that will push the lost event from the timer thread. This avoid blocking the
upstream thread while we push and sync the event.

fa1ef3328b jitterbuffer: rearrange timer update code
Also update the timers when retransmission is disabled. We need to

we need to remove those timers when the packet finally arrives.
