ioquake3.x86_64.exe can't load x86 OpenAL32.dll. Using separate
library names allows shipping OpenAL for both architectures.
Though since the dll name is saved in the config file, using both
clients on the same computer will cause one client arch to always
try to load the wrong OpenAL dll and then fallback to the correct
default OpenAL dll. I guess it could be fixed by using separate
cvar names for s_alDriver.
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.)
If OpenAL source isn't playing, often what happens is: queued buffers is 0 and processed buffers is non-0.
S_AL_StreamUpdate won't play the steam if queued buffers 0.
So start the stream in S_AL_RawSamples.
Don't assume we have unlimited OpenAL buffers.
Detach buffers from sources by setting AL_BUFFER to 0. Cannot delete buffers on OS X immediately after alSourceUnqueueBuffers.
Free unprocessed stream and music buffers.
Free unused sfx buffers when sound file exists and fails loading into OpenAL (though I haven't seen it fail).
- 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
- Don't play sources outside the listening range (Thanks Kpaxian for bringing this to my attention)
- Handle previously unhandled errors for old OpenAL sample implementation which does not support AL_SEC_OFFSET (sounds won't be synchronized then),
thanks to Tequila from SmokingGuns for reporting this.
