Server/client VoIP protocol is handled by adding new cvars
cl_voipProtocol and sv_voipProtocol, sv_voip and cl_voip
are used to auto set/clear them. All users need to touch
are cl/sv_voip as 0 or 1 just like before.
Old Speex VoIP packets in demos are skipped.
New VoIP packets are skipped in demos if sv_voipProtocol
doesn't match cl_voipProtocol.
Notable difference between usage of speex and opus codecs,
when using Speex client would be sent 80ms at a time.
Using Opus, 60ms is sent at a time. This was changed because
the Opus codec supports encoding up to 60ms at a time.
(Simpler to send only one codec frame in a packet.)
- Fix Ryan's FIXME and have voip packet buffer on the server dynamically allocated via Z_Malloc and store pointers in a circular buffer
- Improve voip target parsing on top of Ben Millwood's patch
- Add new "spatial" target where speaker is spatialized in 3d space and can be heard by all clients in hearing range (s_alMaxDistance)
(#4467)
- Decrease voip sound lengths from 240ms to 80ms per voip packet to mitigate udp packet loss and decrease latency
- Protocol version incremented to 71
- Make server send packet fragments and queued packets when server is idle
- Voip protocol detection is tied to com_protocol making past-end-of-message reading unncessary
- Use Hunk_AllocateTempMemory() for buffering VOIP packets and fix buffering scheme that ryan hates so much
- Disable packet scrambling for new protocol as it is useless now
- Get rid of the old packet scrambling functions predating latest point release
- Use Hunk_AllocateTempMemory() for netchan packet queue to fix memory leak when client gets disconnected with packets in the queue
- Use Hunk_AllocateTempMemory() for download blocks to fix memory leak when client gets disconnected with download blocks in the queue
- Fix SV_RateMsec to account for udp/udp6 packet lengths
* differing screen resolutions and network settings are now honoured when changing fs_game
* Fix hunk memory leak on game_restart
* Move cls.state and cls.servername to clc so connection state is fully preserved over game_restart
* Revert back to previous fs_game after disconnecting from a server that triggered a game_restart
* Fix error dialog popping up after every game_restart if an error happened previously (reported by Ensiform)
- Fixed that not all commands added by CL_Init() would be removed by CL_Shutdown()
- Retains full compatibility to the old but unsecure protocol between clients and servers
- Harden the connection process against DoS attacks, possibly connected to UDP spoofing
ignoring completely' from r1459; it can't ever work acceptably, especially on
azerty/qwertz layouts
* Make the ordering of the output from in_keyboardDebug more sensible
* Add cl_consoleKeys cvar, a space delimited list of key names or characters
that toggle the console
We fake a server packet and write it directly to the demo file at the point
where we'd transmit to the server. This is a little nasty, but it seems to
be the most reasonable solution.
