Detailed Description

Contains AVC configuration parameters, initialised from an "avcC" file segment or from an SDP "fmtp" attribute string, held as lists of SPS and PPS sub-structures.

In practice there is often only one SPS and one PPS.

std::string Gr::Avc::Configuration::nalus ( ) const

Returns the NALU byte-stream comprising the four-byte 00-00-00-01 start-code followed by the byte-stuffed NALUs separated by the three-byte 00-00-01 marker.

Definition at line 291 of file gravc.cpp.

size_t Gr::Avc::Configuration::ppsCount ( ) const

Returns pps().size().

This will be smaller than spsList.size() if there are parsing errors.

Definition at line 276 of file gravc.cpp.

const std::vector< std::string > & Gr::Avc::Configuration::ppsList ( ) const

Returns a list of binary strings for the pps structures.

The strings are byte-stuffed and start with the nalu type in the low bits of the first character position.

size_t Gr::Avc::Configuration::spsCount ( ) const

Returns sps().size().

This will be smaller than spsList.size() if there are parsing errors.
