Detailed Description

Abstract interface to be notified of PES packets using a PESDemux.

All hooks are optional, ie. they have an empty default implementation.

Member Function Documentation

◆ handlePESPacket()

virtual void ts::PESHandlerInterface::handlePESPacket ( PESDemux demux,
const PESPacket packet 
)
virtual

This hook is invoked when a complete PES packet is available.

Parameters
[in,out]demuxA reference to the PES demux.
[in]packetThe demultiplexed PES packet.

◆ handleVideoStartCode()

virtual void ts::PESHandlerInterface::handleVideoStartCode ( PESDemux demux,
const PESPacket packet,
uint8_t  start_code,
size_t  offset,
size_t  size 
)
virtual

This hook is invoked when a video start code is encountered.

Parameters
[in,out]demuxA reference to the PES demux.
[in]packetThe demultiplexed PES packet.
[in]start_codeThe XX in start code (00 00 01 xx).
[in]offsetOffset of the start code (00 00 01 xx) in the PES packet payload
[in]sizeSize of the video payload (up to next start code).

◆ handleNewMPEG2VideoAttributes()

virtual void ts::PESHandlerInterface::handleNewMPEG2VideoAttributes ( PESDemux demux,
const PESPacket packet,
const MPEG2VideoAttributes attr 
)

◆ handleAccessUnit()

virtual void ts::PESHandlerInterface::handleAccessUnit ( PESDemux demux,
const PESPacket packet,
uint8_t  nal_unit_type,
size_t  offset,
size_t  size 
)
virtual

This hook is invoked when an AVC, HEVC or VVC access unit (aka "NALunit") is found.

Parameters
[in,out]demuxA reference to the PES demux.
[in]packetThe demultiplexed PES packet.
[in]nal_unit_typeNALunit type.
[in]offsetOffset of the start code (00 00 01 xx) in the PES packet payload.
[in]sizeSize of the video payload (up to next start code).

◆ handleSEI()

virtual void ts::PESHandlerInterface::handleSEI ( PESDemux demux,
const PESPacket packet,
uint32_t  sei_type,
size_t  offset,
size_t  size 
)
virtual

This hook is invoked when an AVC, HEVC or VVC SEI (Supplemental Enhancement Information) is found.

Parameters
[in,out]demuxA reference to the PES demux.
[in]packetThe demultiplexed PES packet.
[in]sei_typeSEI type.
[in]offsetOffset of the SEI payload in the PES packet payload.
[in]sizeSize of the SEI payload.

◆ handleNewAVCAttributes()

virtual void ts::PESHandlerInterface::handleNewAVCAttributes ( PESDemux demux,
const PESPacket packet,
const AVCAttributes attr 
)
virtual

This hook is invoked when new AVC attributes are found in a video PID.

Parameters
[in,out]demuxA reference to the PES demux.
[in]packetThe demultiplexed PES packet.
[in]attrVideo attributes.

◆ handleNewHEVCAttributes()

virtual void ts::PESHandlerInterface::handleNewHEVCAttributes ( PESDemux demux,
const PESPacket packet,
const HEVCAttributes attr 
)
virtual

This hook is invoked when new HEVC attributes are found in a video PID.

Parameters
[in,out]demuxA reference to the PES demux.
[in]packetThe demultiplexed PES packet.
[in]attrVideo attributes.

◆ handleIntraImage()

virtual void ts::PESHandlerInterface::handleIntraImage ( PESDemux demux,
const PESPacket packet,
size_t  offset

Parameters
[in,out]demuxA reference to the PES demux.
[in]packetThe demultiplexed PES packet.
[in]offsetOffset in the PES packet payload where the image is found. This is informational only, the exact semantics depends on the video codec.

virtual

This hook is invoked when new AC-3 attributes are found in an audio PID.

Parameters
[in,out]demuxA reference to the PES demux.
[in]packetThe demultiplexed PES packet.
