Stefano Sabatini	b2bcbcd999	lavfi/super2xsai: simplify code updating the color matrix at each y iteration ... Remove duplicated out-of-loop init code, and do color matrix initialization at the beginning of each y iteration. Allow factorization and avoid an useless matrix update in the last iteration.	2012-06-16 00:30:48 +02:00
Stefano Sabatini	4ebb46eb14	lavfi/super2xsai: fix table used to update color matrix at the end of each y loop ... The previous table appears to be wrong (it was copied from the original MPlayer super2xsai filter in order to keep binary compatibility). The new table is consistent with the init code and apparently fixes a combing artifact on the left edge of the generated image.	2012-06-16 00:30:42 +02:00
Stefano Sabatini	b7a7830dd4	lavfi: port 2xsai filter from libmpcodecs ... Partially based on the port by Niel van der Westhuizen <nielkie@gmail.com>, done for GCI 2010. Same output as the original filter and as fast. See thread: Subject: [FFmpeg-devel] [PATCH] Port MPlayer 2xSaI filter to libavfilter Date: Thu, 25 Nov 2010 01:31:24 +1000	2012-04-13 00:14:06 +02:00
