I had tested with the sample from ticket #503 yesterday. Using the following sample: http://samples.ffmpeg.org/FLV/flash_with_alpha/300x180-Scr-f8-056alpha.flv I get less nice results: $ ffmpeg -i 300x180-Scr-f8-056alpha.flv -vframes 1 -vf palettegen pal.png $ ffmpeg -i 300x180-Scr-f8-056alpha.flv -i pal.png -lavfi paletteuse -vframes 1 out.png Transparency in the output file is not correct, I wonder if the line "if (c1[0] == 0 && c2[0] == 0" should be more something like "if (c1[0] < 128 && c2[0] < 128)" (or with a threshold variable). The results get worse with more frames and apng output: Large blocks "disappear" from the output file, this looks quite nice without your patch (but without transparency).
