Paul Kendall	143d7f1443	left_block intialisation optimisation. This patch changes the left_block initialisation code in the fill_caches function from individual array element setters to a simple pointer to a pre-initialised array.

Michael Niedermayer	0af6967ee7	chroma_format_idc=0 aka grayscale support. Can be disabled by removing #define ALLOW_NOCHROMA in case the extra if() slow the code down measurably. Fixes at least FRExt/HPCAMOLQ_BRCM_B.264 FRExt/HPCVMOLQ_BRCM_B.264 Originally committed as revision 14407 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Michael Niedermayer	af8c5e08d7	Revert r14404 Remove another 2 incorrect checks. These would ignore fields of different parity. I was wrong, i thought pic_stricture is the current pic structure. But it does not make a difference either way on the reference bitstreams. Originally committed as revision 14405 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Michael Niedermayer	d9022d38fb	Remove another 2 incorrect checks. These would ignore fields of different parity. Originally committed as revision 14404 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago

Michael Niedermayer	b3e93fd408	indent Originally committed as revision 14399 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Michael Niedermayer	d4f7d83866	Rewrite fill_default_ref_list(), the old code was obfuscated beyond repair with hacks. new code is ~60lines old was ~200 Fixes at least: FRExt/HCHP2_HHI_A.264 one sample also get decoded much better: FRExt/FRExt1_Panasonic.avc (PSNR 11 -> 80) (no i do not know why, the old code was too a big mess to figure out what it did) Originally committed as revision 14398 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Michael Niedermayer	37dcf83077	Do not scare the user with error messages when everything is ok. Originally committed as revision 14396 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago

Michael Niedermayer	9296f5d81a	Simplify strange obfuscated code in MMCO_LONG handling. Note, this might change behavior for invalid bitstreams. Originally committed as revision 14381 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Michael Niedermayer	357282c6f3	Set field_poc (it was half uninitialized before) and use it instead of the fragile first_field check to determine if we have 2 fields at the end. Originally committed as revision 14380 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago

Michael Niedermayer	5a78bfbde7	qscale has a range of 0..51 we thus do not need a 256 entry table and neither need to and it with 0xFF. Originally committed as revision 14336 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Michael Niedermayer	a82688b003	Setting chroma_qp to 0 for PCM blocks is really an interesting minor optimization, more interresting would it have been had the author thought about what value chroma_qp would have for the following MB. Or failing that, had actually tested the code. So this reverts this non-functional optimization, and makes the code work.
