Definition of class SequenceHeaderByteIO.
Definition: accessunit_byteio.h:51
void OutputVideoDepth()
Outputs number of bits used to compress input signal.
void Input()
Reads sequence information from Dirac byte-format.
void OutputPictureCodingMode()
Outputs how input was coded - i.e.
const SourceParams & m_src_params
Source paramters for intput/output.
Definition: codingparams_byteio.h:118
Parameters relating to the source material being encoded/decoded.
Definition: common.h:288
void InputPictureCodingMode()
Reads picture coding mode - 0 - frames, 1 - fields.
Represents compressed sequence-parameter data used in an AccessUnit.
Definition: codingparams_byteio.h:58
void InputVideoDepth()
Reads number of bits used to compress input signal.
Class ByteIO - top-level class for reading/writing bytes to a stream
Definition: byteio.h:72

Parameters common to coder and decoder operation.
Definition: common.h:1098
const SourceParams & m_default_source_params
Default source parameters.
Definition: codingparams_byteio.h:128
CodecParams & m_codec_params
