Thomas Mundt	a7f6bfdc18	avfilter/interlace: prevent over-sharpening with the complex low-pass filter The complex vertical low-pass filter slightly over-sharpens the picture. This becomes visible when several transcodings are cascaded and the error potentises, e.g. some generations of HD->SD SD->HD. To prevent this behaviour the destination pixel must not exceed the source pixel when the average of the pixels above and below is less than the source pixel. And the other way around. Tested and approved in a visual transcoding cascade test by video professionals. SSIM/PSNR test with the first generation of an HD->SD file as a reference against the 6th generation(3 x SD->HD HD->SD): Results without the patch: SSIM Y:0.956508 (13.615881) U:0.991601 (20.757750) V:0.993004 (21.551382) All:0.974405 (15.918463) PSNR y:31.838009 u:48.424280 v:48.962711 average:34.759466 min:31.699297 max:40.857847 Results with the patch: SSIM Y:0.970051 (15.236232) U:0.991883 (20.905857) V:0.993174 (21.658049) All:0.981290 (17.279202) PSNR y:34.412108 u:48.504454 v:48.969496 average:37.264644 min:34.310637 max:42.373392 Signed-off-by: Thomas Mundt <tmundt75@gmail.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	8 years ago

Clément Bœsch	f8519529cf	lavfi/coreimage: reduce dependency scope from QuartzCore to CoreImage What is required by the filter is CoreImage, there is no QuartzCore usage. QuartzCore/CoreImage.h is simply an include to CoreImage/CoreImage.h.	8 years ago

Nicolas George	f5a9c63401	lavfi: guess a timestamp for compat status change. Use the earliest input with the same status. If that fails, print a warning and use the earliest source. With this change, simple filter forward correctly the timestamp of EOF. Filters that are supposed to change it should be updated to actually forward it.	8 years ago
