Cameron Gutman c9e5660b8c Track the last sent controller packet by controller index 
This avoids stacking batch delay when multiple controller are connected
 2023-10-16 22:02:55 -05:00
Cameron Gutman 615b5e2bba Rewrite input batching for mouse and gamepad sensors 
The old method was too inflexible (depending on consecutive events to batch) that it couldn't
really handle stressful cases like high polling rate mice combined with multiple gamepads
reporting motion sensor events.

Cameron Gutman 47fa51034a Revert change to send mouse position and gamepad events as unreliable

Cameron Gutman 162c581754 Initialize strtokCtx to NULL for first call to strtok_r() 
Apparently some strtok_r() implementations require this.
 2023-09-27 01:27:12 -05:00
Cameron Gutman 1be56269a3 Fix handling of duplicate packets when OOS data was also received 
It's possible for a sequence of packets seqnums like 2, 0, 1, 2 to end up hitting the fast path
again after filling in gap of OOS packets. The fast path assumes duplicate packets are caught
by the next contiguous sequence number check, but this is only true if that value is kept updated.

Since the slow path doesn't update the next contiguous sequence number, it's no longer safe to
use the fast path for the remaining packets in the frame because duplicate packets would be
mishandled.

Queuing duplicate packets violates all sorts of queue assumptions and can cause us to return
corrupt data to the decoder or attempt an FEC recovery without enough shards.

Cameron Gutman 20130e210b Invoke control stream callbacks on a separate thread 
Time spent processing client callbacks would contribute to increased control stream latency,
which means higher RTTs, more lengthy waits before retransmissions, and higher client-reported
network latency stats.

Cameron Gutman c13f4a323f Use connected datagram sockets for audio and video 
This ensures unwanted data from other sources is dropped and that our own source address doesn't change while streaming.
 2023-09-12 23:29:05 -05:00
Cameron Gutman ec6713fd80 Improve checks for runt video packets 
Since we always allocate fixed size these aren't likely to be exploitable,
but we ought to fix them anyway. Worst case, we will just read some garbage
and generate corrupt video output.
