Check carefully (zoom 800%), comparing to the reference group from: https://en.wikipedia.org/wiki/Comparison_gallery_of_image_scaling_algorithms Or change the `-pix_fmt pal8` from the above command to `-pix_fmt rgb24` then render one, compare them. -- Ticket URL: <https://trac.ffmpeg.org/ticket/1261#comment:9> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#7822(undetermined:new): x264 possible encoding error with png source since N-93471-gf8fa8bbf22

#7822: x264 possible encoding error with png source since N-93471-gf8fa8bbf22 -------------------------------------+------------------------------------- Reporter: JouMxyzptlk | Type: defect Status: new | Priority: normal Component: | Version: undetermined | unspecified Keywords: x264 | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: Last working build: ffmpeg-20190325-6e42021-win64-static.zip Up to now everything from ffmpeg-20190328-f8fa8bb-win64-static.zip and later produces those errors. Mplayer Home Cinema shows the error. ffdshow shows the error as well. avidemux (latest build) does not show the decoding error, I can stream- copy, but the resulting video still shows that error. Tested with Ryzen 7 2700X on Windows 10 x64 1809 (latest updates) and on i7-4960X on Server 2019 with latest updates: Same result although quite different hardware. Other CPU load does not matter, I/O load does not matter as well. Reproduce: Get test input data from from: http://www.joumxyzptlk.de/tmp/ffmpeg /testdata-4k.7z For comparison: Correct result with ffmpeg-20190325-6e42021-win64-static.zip http://www.joumxyzptlk.de/tmp/ffmpeg/ffmpeg-h264-last-working- version-N-93139-ga9452fe6dc.mkv {{{ C:\Users\Jou>C:\prog\ffmpeg\bin\ffmpeg.exe -framerate 25 -i "D:\tmp \testdata-4k\%06d.png" -vcodec libx264 -preset:v veryslow -tune:v Animation -crf 20 "D:\tmp\ffmpeg-h264-last-working-version.mkv" ffmpeg version N-93139-ga9452fe6dc Copyright (c) 2000-2019 the FFmpeg developers built with gcc 8.2.1 (GCC) 20190212 configuration: --enable-gpl --enable-version3 --enable-sdl2 --enable- fontconfig --enable-gnutls --enable-iconv --enable-libass --enable- libdav1d --enable-libbluray --enable-libfreetype --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libopenjpeg --enable-libopus --enable-libshine --enable-libsnappy --enable-libsoxr --enable-libtheora --enable-libtwolame --enable-libvpx --enable-libwavpack --enable-libwebp --enable-libx264 --enable-libx265 --enable-libxml2 --enable-libzimg --enable-lzma --enable-zlib --enable-gmp --enable- libvidstab --enable-libvorbis --enable-libvo-amrwbenc --enable-libmysofa --enable-libspeex --enable-libxvid --enable-libaom --enable-libmfx --enable-amf --enable-ffnvcodec --enable-cuvid --enable-d3d11va --enable- nvenc --enable-nvdec --enable-dxva2 --enable-avisynth --enable-libopenmpt libavutil 56. 26.100 / 56. 26.100 libavcodec 58. 47.102 / 58. 47.102 libavformat 58. 26.101 / 58. 26.101 libavdevice 58. 6.101 / 58. 6.101 libavfilter 7. 48.100 / 7. 48.100 libswscale 5. 4.100 / 5. 4.100 libswresample 3. 4.100 / 3. 4.100 libpostproc 55. 4.100 / 55. 4.100 Input #0, image2, from 'D:\tmp\testdata-4k\%06d.png': Duration: 00:00:03.96, start: 0.000000, bitrate: N/A Stream #0:0: Video: png, rgb24(pc), 3840x2160, 25 fps, 25 tbr, 25 tbn, 25 tbc Stream mapping: Stream #0:0 -> #0:0 (png (native) -> h264 (libx264)) Press [q] to stop, [?] for help [libx264 @ 000001b01b341440] using cpu capabilities: MMX2 SSE2Fast SSSE3 SSE4.2 AVX FMA3 BMI2 AVX2 [libx264 @ 000001b01b341440] profile High 4:4:4 Predictive, level 6.0, 4:4:4, 8-bit [libx264 @ 000001b01b341440] 264 -

#7774: ProRes Scanned Alpha omitting last run of a slice if it's length 0 ---------------------------------+--------------------------------------- Reporter: vinlai | Type: defect Status: new | Priority: normal Component: avcodec | Version: unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | ---------------------------------+--------------------------------------- Alpha encoded using prores_ks produces slices that omits the final run of a slice if it is length 0. This is the correct behaviour for non-alpha channels, however, the termination conditions are different for alpha. ---- RDD36-2015: 7.1.1.4 AC Coefficients They are terminated either by a non-zero array element—a level—or by reaching the end of the array. 7.1.2 Scanned Alpha They terminate when one of the following occurs: two consecutive array elements have different values; the end of the array is reached; or the maximum permissible run length, 2048, is achieved. ---- In summary, encoded Alpha should not be omitting the final run of a slice even if it is length 0.
