Andreas Cadhalpun	3526a120f9	snow: remove an obsolete av_assert2 It asserts that the frame linesize is larger than 37, but it can be smaller and decoding such frames works. Before commit `cc884a35` src_stride > 7MB_SIZE was necessary, because the blocks were interleaved in the tmp buffer and the last block was added with an offset of 6MB_SIZE. It was changed for src_stride <= 7MB_SIZE to write the blocks sequentially, hence the larger tmp_step. After that the assert was only necessary to make sure that the buffer remained large enough. Since commit `bd2b6b33` s->scratchbuf is used as tmp buffer. As part of commit `86e107a7` the minimal scratchbuf size was increased to 2567MB_SIZE, which is enough for any src_stride <= 7MB_SIZE. Also add a comment explaining the tmp_step calculation. Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com>	9 years ago

Michael Niedermayer	bf301258b4	avcodec/snowenc: add FF_MPV_COMMON_OPTS This fixes the ratecontrol code with snow adding FF_MPV_COMMON_OPTS is needed as the generic rate control options are currently in the (unrelated) MpegEncContext Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago

Mans Rullgard	8540dcfd7a	snow: fix integer overflows The way these values are used, they should have an unsigned type. A similar change was made for mpegvideo in `cb66847`. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Luca Barbato	7f1b427018	snow: split snow in snowdec and snowenc The common non inlined code goes in snow.c, the common inlined code in snow.h, tables move in snowdata.h (included only by snow.c)	13 years ago

Måns Rullgård	05aec7bb87	Separate DWT from snow and dsputil This moves the DWT functions from snow.c and dsputil.c to a file of their own. A new struct, DWTContext, holds the function pointers previously part of DSPContext. Originally committed as revision 22522 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	cc1e807f4c	snow: remove unused stub functions w53_32_c() and w97_32_c() are defined as stubs when snow encoder is disabled. In this case, those functions are not referenced at all and do thus not need to be defined. Originally committed as revision 22448 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Stefano Sabatini	987903826b	Globally rename the header inclusion guard names. Consistently apply this rule: the guard name is obtained from the filename by stripping the leading "lib", converting '/' and '.' to '_' and uppercasing the resulting name. Guard names in the root directory have to be prefixed by "FFMPEG_". Originally committed as revision 15120 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Michael Niedermayer	d593e32983	use 16bit IDWT (a SIMD implementation of it should be >2x faster then with the old 32bit code) disable mmx/sse2 optimizations as they need a rewrite now Originally committed as revision 10218 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Michael Niedermayer	ce611a27be	Change rounding of the horizontal DWT to match the vertical one. This allows some simplifications and optimizations and should not have any effect on quality. Originally committed as revision 10172 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
