Aurelien Jacobs	6ff3b2b838	Fix A32_BITSTREAM_READER compilation on x86 Originally committed as revision 6102 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
Michael Niedermayer	d6bea62338	make mpa_decode_header() 10 times faster Originally committed as revision 6101 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
Michael Niedermayer	731d0b1aaa	another silly typo which surprisingly neither valgrind nor cmp of the file output cought Originally committed as revision 6100 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
Michael Niedermayer	d37bb9d8c1	10l found by valgrind Originally committed as revision 6099 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
Michael Niedermayer	06e7fb82a4	remove duplicated parser, people who pass random gibblets of the bitstream into the decoder will have to pass it through a AVParser like for all other codecs too remove silly internal buffering architecture (removes 1 memcpy() of the bitstream) mp3on4 and mp3adu untested Originally committed as revision 6098 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
Michael Niedermayer	6e4703cac7	2nd try of skip_bits_long() for the ALT reader 1st try for the LIBMPEG2 reader simplify init_get_bits() Originally committed as revision 6097 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
Michael Niedermayer	a42ec9f484	make A32 reader align its ptr during init no matter what missaligned mess is given to it Originally committed as revision 6096 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
Michael Niedermayer	3dddf21fcc	3rd try :) Originally committed as revision 6095 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago

Michael Niedermayer	5a7bd28335	move align_get_bits() to .h to avoid conflicts between different bitstream readers in different codecs add a skip_bits_long() which can skip by any amount in any direction (several codecs contain half working hacks to do that) Originally committed as revision 6093 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago

Michael Niedermayer	f617adedc8	replace MULL with asm too, no significnat speedup but its probably better to not take any chances, some versions of gcc will almost certainly mess it up too if they can Originally committed as revision 6049 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago

Michael Niedermayer	0bd2483a75	replace MULL by MULH + shift in dct32() (code is very slightly faster, and the compiler should be able to optimize the shift away on 64bit archs) Originally committed as revision 6045 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
