Subject: [Ffmpeg-devel] [PATCH] Add sws_getCachedContext() to swscale library
Originally committed as revision 19667 to svn://svn.mplayerhq.hu/mplayer/trunk/libswscale
the +-1 issue is limited to >2tap vertical filters, so bilinear upscale was unaffected
the new code is sometime faster sometimes slower but the difference is significant (~20%) so its optional and enabled with arnd=1
Originally committed as revision 19177 to svn://svn.mplayerhq.hu/mplayer/trunk/libswscale
removing sws - cpudetect dependancy (note rgb2rgb still needs it)
moving mplayer specific stuff from swscale.c -> vf_scale.c
Originally committed as revision 9976 to svn://svn.mplayerhq.hu/mplayer/trunk/postproc
x/yInc bugfix (bug was introduced during the global var removial)
more emms & no messing with ARCH_X86 (=workaround against not cleared mmx state somewhere)
sharpening filter (-ssf cs=<int> & -ssf ls=<int>)
Originally committed as revision 4298 to svn://svn.mplayerhq.hu/mplayer/trunk/postproc
-ssf cgb=<float> -> chrominance gaussian blur (nice to improve picture quality)
-ssf lgb=<float> -> luminance gaussian blur (dunno what its good for)
-ssf chs=<int> -> shift chrominance horizontally
-ssf cvs=<int> -> shift chrominance vertically
these will only work if the swscaler is used at all
Originally committed as revision 4295 to svn://svn.mplayerhq.hu/mplayer/trunk/postproc
dynamic memory allocation for the buffers (needed for the filter stuff)
Originally committed as revision 4291 to svn://svn.mplayerhq.hu/mplayer/trunk/postproc
experimental upscaling mode (-sws 3)
general convolution filters support (unfinished)
bugfix for bicubic upscaling
assertion checking if defined MP_DEBUG
checking of the input/output size instead of segfault if its very large
Originally committed as revision 4277 to svn://svn.mplayerhq.hu/mplayer/trunk/postproc
-sws command line option (0 -> fast_bilinear, 1->bilinear, 2->bicubic)
Originally committed as revision 3273 to svn://svn.mplayerhq.hu/mplayer/trunk/postproc
green line at bottom bugfix
green lines in yuv2yuv scaler bugfix
Originally committed as revision 3210 to svn://svn.mplayerhq.hu/mplayer/trunk/postproc
someone who knows a bit about vo_odivx could add support for it ...
Originally committed as revision 2520 to svn://svn.mplayerhq.hu/mplayer/trunk/postproc
