Update of /cvsroot/mplayer/main/postproc
In directory mplayer:/var/tmp.root/cvs-serv5109/postproc

Modified Files:
	postprocess.c postprocess.h 
Log Message:
temporal noise reducer in C (-pp 0x100000)
setting the thresholds from the commandline requires postprocess2() / getPpModeByNameAndQuality() (someone could perhaps modify mplayer so that they are beiing used, iam too lazy for it ;)

 TODO:
 verify that everything workes as it should (how?)
 reduce the time wasted on the mem transfer
-implement dering
 implement everything in C at least (done at the moment but ...)
 unroll stuff if instructions depend too much on the prior one
 we use 8x8 blocks for the horizontal filters, opendivx seems to use 8x4?
 move YScale thing to the end instead of fixing QP
 write a faster and higher quality deblocking filter :)
-do something about the speed of the horizontal filters
 make the mainloop more flexible (variable number of blocks at once
 	(the if/else stuff per block is slowing things down)
 compare the quality & speed of all filters
 split this huge file
-fix warnings (unused vars, ...)
-noise reduction filters
 border remover
 optimize c versions
+try to unroll inner for(x=0 ... loop to avoid these damn if(x ... checks
 ...
