Rostislav Pehlivanov	053900ca4c	dirac: add more parse codes from the specifications The specs define some more overlapping and some rarely used parse codes which were missing. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>	9 years ago
Rostislav Pehlivanov	7d8891593c	dirac_parser: add exceptions for Dirac inter parse codes Forgotten from previous commit. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>	9 years ago
Rostislav Pehlivanov	a849ebb54e	dirac_parser: Improve parsing and silence pointless warnings The parser scans for "BBCD" to appear in the bitstream which indicate a parse info header and once that happens, checks if the parse offsets are sane. Since random BBCD strings might appear in the bitstream the parser will emit a pointless warning if that happens. This commit improves parsing by checking for a valid parse code as well as keeping the original checks for valid parse offsets. The warnings were removed as they serve no real purpose.
