static Void _byteStreamNALUnit	(	InputByteStream &	bs,
		vector< uint8_t > &	nalUnit,
		AnnexBStats &	stats
	)

static

Parse an AVC AnnexB Bytestream bs to extract a single nalUnit while accumulating bytestream statistics into stats.

If EOF occurs while trying to extract a NALunit, an exception of std::ios_base::failure is thrown. The contsnts of stats will be correct at this point.

Definition at line 62 of file AnnexBread.cpp.

Void TDecBinCABAC::align ( )

virtual

Implements TDecBinIf.

Bool byteStreamNALUnit	(	InputByteStream &	bs,
		vector< uint8_t > &	nalUnit,
		AnnexBStats &	stats
	)

Parse an AVC AnnexB Bytestream bs to extract a single nalUnit while accumulating bytestream statistics into stats.

Returns false if EOF was reached (NB, nalunit data may be valid), otherwise true.

Definition at line 182 of file AnnexBread.cpp.

static Void calcAndPrintHashStatus	(	TComPicYuv &	pic,
		const SEIDecodedPictureHash *	pictureHashSEI,
		const BitDepths &	bitDepths,
		UInt &	numChecksumErrors
	)

static

Calculate and print hash for pic, compare to picture_digest SEI if present in seis. seis may be NULL. Hash is printed to stdout, in a manner suitable for the status line. Theformat is: [Hash_type:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx,(yyy)] Where, x..x is the hash yyy has the following meanings: OK - calculated hash matches the SEI message ***ERROR*** - calculated hash does not match the SEI message unk - no SEI message was available for comparison
