Juliusz Chroboczek fc9f28fd68 Minor cleanups. 2022-04-23 18:43:01 +02:00
Juliusz Chroboczek 9093339b62 Rework handling of buffered keyframes. 
Instead of buffering the last keyframe, we merely keep track of its
seqno, and use the main cache for recovering.  We also send the whole
sequence of packets rather than just the keyframe itself.

Juliusz Chroboczek 9b1d814b58 Rework packetcache loss statistics. 
Don't maintain loss, which is too error-prone.  Instead, maintain
expected and received packet counts, and compute loss from that.

Juliusz Chroboczek d0ef6a2c0f Fix loss accounting for multiple packets. 2021-04-28 00:07:19 +02:00
Juliusz Chroboczek f0cf9ae141 Fix loss statistics on NACK. 
Since we don't use a separate RTX SSID, we must explicitly account for
NACKed packets in our loss statistics.

Juliusz Chroboczek a189e0ad46 Implement packetcache.Last. 2020-10-11 22:08:03 +02:00
Juliusz Chroboczek e6bf9338dd Document packetcache. 2020-10-08 18:46:52 +02:00
Juliusz Chroboczek e07a98e355 Deal with reordered keyframes. 2020-10-08 17:58:58 +02:00
Juliusz Chroboczek 86f7594626 Discard old keyframes. 
Avoids seqno wraparound.  Unlikely, but I'm supersticious.

Juliusz Chroboczek 44ae9f82d3 Remodularise packet cache. 2020-10-04 21:08:34 +02:00
Juliusz Chroboczek 4a8e48d146 Take next packet index into account when sending NACKs. 
This avoids sending NACKs for packets in the future.

Juliusz Chroboczek a50e9c6771 Buffer last keyframe. 2020-10-03 16:18:28 +02:00
Juliusz Chroboczek bbd5ce0c75 Remove dead code (cache.GetLast). 2020-10-03 13:15:30 +02:00
Juliusz Chroboczek 94c42ea784 Be more aggressive about growing the packet cache. 
Also add a test.

Juliusz Chroboczek b7a680671d Remove padding in packetcache. 
Since the packet entries are already overdimensioned, there's no
need to add additional padding.
