VideoPacketEncoder

#include <icy/av/videopacketencoder.h>

Inherits: VideoEncoder, PacketProcessor

PacketProcessor that encodes raw video frames (PlanarVideoPacket or VideoPacket) into compressed packets via VideoEncoder.

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

Example:

auto encoder = std::make_sharedav::VideoPacketEncoder(); encoder->iparams = capture->videoCodec(); // decoded format encoder->oparams = av::VideoCodec("H264", "libx264", 640, 480, 30);

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

Public Methods

process

virtual

virtual void process(IPacket & packet)

Process a VideoPacket or PlanarVideoPacket from the stream. Encodes the frame 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.
