Detailed Description

Unified receive path for RTCP and backchannel RTP data.

Provides the #Compy_AudioReceiver interface for applications to receive backchannel audio, and the Compy_RtpReceiver demuxer that routes incoming data to either RTCP handling or audio callbacks.

Macro Definition Documentation

◆ Compy_AudioReceiver_IFACE

#define Compy_AudioReceiver_IFACE

Value:

    vfunc99(                                                                   \
        void, on_audio, VSelf99, uint8_t payload_type, uint32_t timestamp,     \
        uint32_t ssrc, U8Slice99 payload)

Application callback interface for receiving backchannel audio data.

See Interface99 for the macro usage.

Function Documentation

◆ Compy_RtpReceiver_feed()

int Compy_RtpReceiver_feed	(	Compy_RtpReceiver *	self,
		uint8_t	channel_type,
		const uint8_t *	data,
		size_t	len
	)

Feeds raw received data into the receiver for demuxing.

Parameters

[in]	self	The receiver.
[in]	channel_type	Either COMPY_CHANNEL_RTCP or COMPY_CHANNEL_RTP.
[in]	data	The raw packet data.
[in]	len	Length of `data`.

Precondition: self != NULL; data != NULL

Returns: 0 on success, -1 on parse error.

◆ Compy_RtpReceiver_new()

Compy_RtpReceiver * Compy_RtpReceiver_new	(	Compy_Rtcp *	rtcp,
		Compy_AudioReceiver	audio_receiver
	)

Creates a new RTP receiver for demuxing incoming data.
