Or rather only the cut off apng files cause this (the ones in the bottom row on the page) This only happens when I play them with ffplay. ffmpeg and ffprobe only output one warning (or error) How to reproduce: {{{ PS C:\Users\Felix\Downloads> ffplay .\spinfox_cut53.png ffplay version N-91273-g67747c89ad Copyright (c) 2003-2018 the FFmpeg developers built with gcc 7.3.0 (GCC) configuration: --enable-gpl --enable-version3 --enable-sdl2 --enable- bzlib --enable-fontconfig --enable-gnutls --enable-iconv --enable-libass --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 libavutil 56. 18.102 / 56. 18.102 libavcodec 58. 20.101 / 58. 20.101 libavformat 58. 17.100 / 58. 17.100 libavdevice 58. 4.101 / 58. 4.101 libavfilter 7. 25.100 / 7. 25.100 libswscale 5. 2.100 / 5. 2.100 libswresample 3. 2.100 / 3. 2.100 libpostproc 55. 2.100 / 55. 2.100 [apng @ 000001bc46816f80] In-stream tag=[233]_X[199] (0xC7585FE9) len=447601638 is not implemented.

The warning is likely caused by the incomplete file (I guess) and therefore it's correct that it's shown; but it would be enough if it would be shown once. -- Ticket URL: <https://trac.ffmpeg.org/ticket/7536> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker _______________________________________________ FFmpeg-trac mailing list FFmpeg-trac@avcodec.org http://ffmpeg.org/mailman/listinfo/ffmpeg-trac
