From 975d4d97e4b9459c3d21b4dc3ecd807e9c330d9a Mon Sep 17 00:00:00 2001 From: Zack Middleton Date: Tue, 10 Dec 2013 21:14:13 -0600 Subject: Use Opus for VoIP 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.) --- src/client/cl_cgame.c | 36 ++++++---------- src/client/cl_input.c | 4 +- src/client/cl_main.c | 108 +++++++++++++++++++++--------------------------- src/client/cl_parse.c | 105 +++++++++++++++++++++++----------------------- src/client/client.h | 21 +++++----- src/client/snd_openal.c | 8 +--- 6 files changed, 127 insertions(+), 155 deletions(-) (limited to 'src/client') diff --git a/src/client/cl_cgame.c b/src/client/cl_cgame.c index 1c7d91cc..23f3010c 100644 --- a/src/client/cl_cgame.c +++ b/src/client/cl_cgame.c @@ -956,37 +956,27 @@ void CL_FirstSnapshot( void ) { #endif #ifdef USE_VOIP - if (!clc.speexInitialized) { + if (!clc.voipCodecInitialized) { int i; - speex_bits_init(&clc.speexEncoderBits); - speex_bits_reset(&clc.speexEncoderBits); + int error; - clc.speexEncoder = speex_encoder_init(&speex_nb_mode); + clc.opusEncoder = opus_encoder_create(48000, 1, OPUS_APPLICATION_VOIP, &error); - speex_encoder_ctl(clc.speexEncoder, SPEEX_GET_FRAME_SIZE, - &clc.speexFrameSize); - speex_encoder_ctl(clc.speexEncoder, SPEEX_GET_SAMPLING_RATE, - &clc.speexSampleRate); - - clc.speexPreprocessor = speex_preprocess_state_init(clc.speexFrameSize, - clc.speexSampleRate); - - i = 1; - speex_preprocess_ctl(clc.speexPreprocessor, - SPEEX_PREPROCESS_SET_DENOISE, &i); - - i = 1; - speex_preprocess_ctl(clc.speexPreprocessor, - SPEEX_PREPROCESS_SET_AGC, &i); + if ( error ) { + Com_DPrintf("VoIP: Error opus_encoder_create %d\n", error); + return; + } for (i = 0; i < MAX_CLIENTS; i++) { - speex_bits_init(&clc.speexDecoderBits[i]); - speex_bits_reset(&clc.speexDecoderBits[i]); - clc.speexDecoder[i] = speex_decoder_init(&speex_nb_mode); + clc.opusDecoder[i] = opus_decoder_create(48000, 1, &error); + if ( error ) { + Com_DPrintf("VoIP: Error opus_decoder_create(%d) %d\n", i, error); + return; + } clc.voipIgnore[i] = qfalse; clc.voipGain[i] = 1.0f; } - clc.speexInitialized = qtrue; + clc.voipCodecInitialized = qtrue; clc.voipMuteAll = qfalse; Cmd_AddCommand ("voip", CL_Voip_f); Cvar_Set("cl_voipSendTarget", "spatial"); diff --git a/src/client/cl_input.c b/src/client/cl_input.c index fdd0c474..48bf51df 100644 --- a/src/client/cl_input.c +++ b/src/client/cl_input.c @@ -789,7 +789,7 @@ void CL_WritePacket( void ) { { if((clc.voipFlags & VOIP_SPATIAL) || Com_IsVoipTarget(clc.voipTargets, sizeof(clc.voipTargets), -1)) { - MSG_WriteByte (&buf, clc_voip); + MSG_WriteByte (&buf, clc_voipOpus); MSG_WriteByte (&buf, clc.voipOutgoingGeneration); MSG_WriteLong (&buf, clc.voipOutgoingSequence); MSG_WriteByte (&buf, clc.voipOutgoingDataFrames); @@ -810,7 +810,7 @@ void CL_WritePacket( void ) { MSG_Init (&fakemsg, fakedata, sizeof (fakedata)); MSG_Bitstream (&fakemsg); MSG_WriteLong (&fakemsg, clc.reliableAcknowledge); - MSG_WriteByte (&fakemsg, svc_voip); + MSG_WriteByte (&fakemsg, svc_voipOpus); MSG_WriteShort (&fakemsg, clc.clientNum); MSG_WriteByte (&fakemsg, clc.voipOutgoingGeneration); MSG_WriteLong (&fakemsg, clc.voipOutgoingSequence); diff --git a/src/client/cl_main.c b/src/client/cl_main.c index fa47988e..6df57b4d 100644 --- a/src/client/cl_main.c +++ b/src/client/cl_main.c @@ -45,6 +45,7 @@ cvar_t *cl_voipSendTarget; cvar_t *cl_voipGainDuringCapture; cvar_t *cl_voipCaptureMult; cvar_t *cl_voipShowMeter; +cvar_t *cl_voipProtocol; cvar_t *cl_voip; #endif @@ -250,8 +251,8 @@ void CL_Voip_f( void ) if (clc.state != CA_ACTIVE) reason = "Not connected to a server"; - else if (!clc.speexInitialized) - reason = "Speex not initialized"; + else if (!clc.voipCodecInitialized) + reason = "Voip codec not initialized"; else if (!clc.voipEnabled) reason = "Server doesn't support VoIP"; @@ -304,6 +305,8 @@ void CL_VoipNewGeneration(void) clc.voipOutgoingGeneration = 1; clc.voipPower = 0.0f; clc.voipOutgoingSequence = 0; + + opus_encoder_ctl(clc.opusEncoder, OPUS_RESET_STATE); } /* @@ -392,7 +395,7 @@ void CL_VoipParseTargets(void) =============== CL_CaptureVoip -Record more audio from the hardware if required and encode it into Speex +Record more audio from the hardware if required and encode it into Opus data for later transmission. =============== */ @@ -422,11 +425,12 @@ void CL_CaptureVoip(void) Com_Printf("Until then, VoIP is disabled.\n"); Cvar_Set("cl_voip", "0"); } + Cvar_Set("cl_voipProtocol", cl_voip->integer ?
