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.

Nicolas George	183ce55b0d	lavfi: split frame_count between input and output. AVFilterLink.frame_count is supposed to count the number of frames that were passed on the link, but with min_samples, that number is not always the same for the source and destination filters. With the addition of a FIFO on the link, the difference will become more significant. Split the variable in two: frame_count_in counts the number of frames that entered the link, frame_count_out counts the number of frames that were sent to the destination filter.	8 years ago

Michael Niedermayer	8baa1d2209	avfilter/vf_paletteuse: enable skip_initial_unpaired Fixes crash due to unprocessed input being passed through This fixes the last segfault caused by mixing 3.0 and 3.1 libs and applications Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
Ganesh Ajjanagadde	6aaac24d72	avfilter/all: propagate errors of functions from avfilter/formats Many of the functions from avfilter/formats can return errors, usually AVERROR(ENOMEM). This propagates the return values. All of these were found by using av_warn_unused_result, demonstrating its utility. Tested with FATE. I am least sure of the changes to avfilter/filtergraph, since I don't know what/how reduce_format is intended to behave and how it should react to errors. Fixes: CID 1325680, 1325679, 1325678.
