AudioPacketEncoder

#include <icy/av/audiopacketencoder.h>

Inherits: AudioEncoder, PacketProcessor

PacketProcessor that encodes raw audio samples (PlanarAudioPacket or AudioPacket) into compressed packets via AudioEncoder.

Drop this into a PacketStream between a source that emits raw audio (e.g. MediaCapture) and a sink that expects encoded data (e.g. WebRtcTrackSender or MultiplexPacketEncoder).

Example:

auto encoder = std::make_sharedav::AudioPacketEncoder(); encoder->oparams = av::AudioCodec("opus", "libopus", 2, 48000);

PacketStream stream; stream.attachSource(capture); stream.attach(encoder, 1, true); stream.attach(&webrtcSender, 5, false); stream.start();

Public Methods

Return	Name	Description
	`AudioPacketEncoder`
	`AudioPacketEncoder`	Deleted constructor.
`void`	`process` `virtual`	Process an AudioPacket or PlanarAudioPacket from the stream. Encodes the samples and emits the resulting compressed packet.
`bool`	`accepts` `virtual`	Accept AudioPacket and PlanarAudioPacket types.

AudioPacketEncoder

AudioPacketEncoder(const AudioPacketEncoder &) = delete

Deleted constructor.

process

virtual

virtual void process(IPacket & packet)

Process an AudioPacket or PlanarAudioPacket from the stream. Encodes the samples and emits the resulting compressed packet.

Protected Methods

Return	Name	Description
`void`	`onStreamStateChange` `virtual`	Called by the PacketStream to notify when the internal Stream state changes. On receiving the Stopped state, it is the responsibility of the adapter to have ceased all outgoing packet transmission, especially in multi-thread scenarios.

onStreamStateChange

virtual

virtual void onStreamStateChange(const PacketStreamState &)

Called by the PacketStream to notify when the internal Stream state changes. On receiving the Stopped state, it is the responsibility of the adapter to have ceased all outgoing packet transmission, especially in multi-thread scenarios.
