Juliusz Chroboczek 3d2089f40f Merge GetRTP and Nack into GetPacket. 
The two function were always called together.  This factors out
the NACKing logic into the track.

Juliusz Chroboczek 36d31f0db8 Maintain a reference to the connection associated to each track. 
This avoids carrying an extra parameter in many places.

Juliusz Chroboczek eec6c8a5b0 Use a partition tail checker in the diskwriter. 
Now that we have our own samplebuilder, we can use the mark bit
to avoid dropping packets before a dropped packet.
 2021-07-11 21:01:10 +02:00
Juliusz Chroboczek e840e53ac2 Switch to our own samplebuilder.

to our own.

Juliusz Chroboczek de78f3ce62 Map entries before the first in packetmap. 
The first time we drop, we may already have mapped a number of
packets with the identity mapping.  Insert an identity mapping
in Drop.

Also extend any existing mapping when inserting out-of-order mappings.

Juliusz Chroboczek 22585e9d10 Handle spatial scalability.

possible.  Yields a 20% saving with VP9.

Juliusz Chroboczek d94e5583cd Rewrite AV1 keyframe detection. 
Metadata OBUs can appear between the sequence header and the first
frame header.
 2021-05-16 14:51:09 +02:00
Juliusz Chroboczek 4435a30a53 Use sequence parameter sets for h.264 keyframe detection. 
RFC 6184 Section 8.5.1 implies that the sender will send a
a sequence parameter set in response to PLI.  Since a keyframe is
useless without parameters, use the SPS to detect keyframes.
