Bjorn Roche	aba926e7d6	lavfi/paletteuse: fix to support transparency This patch enables paletteuse to identify the transparency in incoming video and tag transparent pixels on outgoing video with the correct index from the palette. This requires tracking the transparency index in the palette, establishing an alpha threshold below which a pixel is considered transparent and above which the pixel is considered opaque, and additional changes to track the alpha value throughout the conversion process. This change is a partial fix for https://trac.ffmpeg.org/ticket/4443 However, animated GIFs are still output incorrectly due to a bug in gif optimization which does not correctly handle transparency.

Mark Thompson	e339411691	vaapi: Always free parameter buffers after vaEndPicture() with libva2 This is an ABI change in libva2: previously the Intel driver had this behaviour and it was implemented as a driver quirk, but now it is part of the specification so all drivers must do it.	7 years ago

Tobias Rapp	62bdec806e	avfilter/vf_fps: add eof_action filter option Allows to specify the action to be performed when reading the last frame from the internal FIFO buffer. By default the last frame is written to filter output depending on the timestamp rounding method. When using "pass" action the last frame is passed through if input duration has not been reached yet. Examples using an input file with 25Hz, 1.4sec duration: - "fps=fps=1:round=near" generates an output file of 1sec - "fps=fps=1:round=near:eof_action=pass" generates an output file of 2sec Signed-off-by: Tobias Rapp <t.rapp@noa-archive.com>	7 years ago

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>	7 years ago
