Detailed Description

MPEG2 closed caption parser.

Extracts CEA-608/708 closed caption data from MPEG2 video streams. Searches for:

  • Picture headers (start code 0x00) to determine picture type (I/P/B)
  • User data (start code 0xb2) containing GA94 or CC closed caption payloads

◆ ParsePacket()

CCPictureType CMPEG2CCBitstreamParser::ParsePacket ( DemuxPacket *  pPacket,
std::vector< CCaptionBlock > &  tempBuffer,
std::vector< CCaptionBlock > &  reorderBuffer 
)
overridevirtual

Parse MPEG2 packet for closed caption data.

Scans the packet for MPEG2 start codes and extracts CC data from user data sections. Supports both GA94 and CC data formats.

Parameters
pPacketMPEG2 video packet with Annex B start codes
tempBufferTemporary buffer for CC data from reference frames
reorderBufferReorder buffer for CC data
Returns
Picture type (I_FRAME, P_FRAME, or OTHER)
