This isn't just an FFMpeg crash, it's an entire system crash, i.e. the screen goes black and the computer restarts. The crash is consistent and happens every single time without exception, rendering ffmpeg unusable for our team. Here are the systems I've tested on. The previous 2 MacBooks we were using don't have this crash (regardless of ffmpeg version). Any suggestions to fix this? FFMpeg is totally broken an not usable for Mac users currently. Crashes: Macbook Pro 13" 2019 Macbook Pro 13" 2018 Doesn't crash: Macbook Pro 13" Early 2015 Macbook Air 2018 How to reproduce: {{{ % ffmpeg -y -thread_queue_size 512 -f avfoundation -framerate 30 -async 1 -i "1" -thread_queue_size 512 -f avfoundation -framerate 30 -i "0":"0" -s 640x400 -b:v 356k -aq 64k -filter:a "volume=1.0" -filter_complex "[0]scale=128:80 [pip]; [1][pip] overlay=main_w-overlay_w-10:main_h- overlay_h-10" -vcodec libx264 -pix_fmt yuv420p -r 30 -movflags +faststart "test.mp4" ffmpeg 4.2 built on MacOS 10.14.6 }}} -- Ticket URL: <https://trac.ffmpeg.org/ticket/8110> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#8109(undetermined:new): Long loading delay for VfW codecs in Matroska

#8109: Long loading delay for VfW codecs in Matroska -------------------------------------+------------------------------------- Reporter: Austin | Type: defect Status: new | Priority: normal Component: | Version: git- undetermined | master Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Greetings, I notice a very long loading/parsing delay (20+ seconds) in what appears to be the Matroska decoder when referencing MKV video files that are longer than 30 minutes in length. '''Steps to reproduce:''' '''1)''' Create one hour video files for testing using the attached 640x360 image (~8 GB each): {{{ ffmpeg -loop true -i "MKVTest_640x360.bmp" -t 3600 -c:v utvideo -an -sn -dn -f avi -y "MKVTest.avi" }}} {{{ ffmpeg -loop true -i "MKVTest_640x360.bmp" -t 3600 -c:v utvideo -an -sn -dn -f mov -y "MKVTest.mov" }}} {{{ ffmpeg -loop true -i "MKVTest_640x360.bmp" -t 3600 -c:v utvideo -an -sn -dn -f matroska -write_crc32 false -y "MKVTest.mkv" }}} '''2)''' Stream copy a section of video that is 50 minutes into the test files: {{{ ffmpeg -ss 00:50:00.000 -i "MKVTest.avi" -t 1 -c copy -y "LoadAndSeek.avi" }}} {{{ ffmpeg -ss 00:50:00.000 -i "MKVTest.mov" -t 1 -c copy -y "LoadAndSeek.mov" }}} {{{ ffmpeg -ss 00:50:00.000 -i "MKVTest.mkv" -t 1 -c copy -y "LoadAndSeek.mkv" }}} '''Output Observations:''' The AVI and MOV files are able to stream copy instantly. The MKV file stalls for 20 seconds before transcoding begins. '''Other Observations:''' HuffYUV and MagicYUV are also affected by slow Matroska loading and playback. FFmpeg appears to be creating a MOV file wrapped by Matroska when using Video for Windows lossless codecs. If those codecs are written directly to a MOV file, load and playback are instant. Adding the Matroska wrapper is what appears to slow things down. My assumption is that the Matroska decoder in ffmpeg is the problem because non-ffmpeg media players like MPC-BE are able to instantly play back and seek the MKV file generated by ffmpeg. This suggests the ffmpeg encoder and Matroska file format are performing as expected, and the problem is contained to the ffmpeg decoder. '''Why this bug is significant:''' For video editors that are built on top of ffmpeg (like Shotcut and Kdenlive), the long loading time ripples up to the editor and makes opening a project take a very long time. Playback and seeking are extremely slow for videos longer than 30 minutes, meaning the MKV format is unusable for editing biking videos, wedding event capture, surveillance video, etc. Matroska is an important format because it retains color space and color range metadata for lossless VfW codecs. AVI retains neither, and MOV doesn't have an official color range flag. I'm not aware of any alternative containers for VfW codecs that capture all color metadata, so getting ffmpeg to decode Matroska at the same speed as MPC-BE or a native MOV file would be of great benefit to the libre video editing world. The lossless VfW codecs are popular for proxy editing due to their speed and color accuracy. Thank you in advance for anything you can find. -Austin '''Uncut console output is as follows:''' ffmpeg version N-94664-g0821bc4eee Copyright (c) 2000-2019 the FFmpeg developers built with gcc 9.1.1 (GCC) 20190807 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. 33.100 / 56. 33.100 libavcodec 58. 55.101 / 58. 55.101 libavformat 58. 31.104 / 58. 31.104 libavdevice 58. 9.100 / 58. 9.100 libavfilter 7. 58.101 / 7. 58.101 libswscale 5. 6.100 / 5. 6.100 libswresample 3. 6.100 / 3. 6.100 libpostproc 55. 6.100 / 55. 6.100 Splitting the commandline.

#7901(undetermined:new): Green/null frames at beginning of decoding with qsv decoders

#7901: Green/null frames at beginning of decoding with qsv decoders -------------------------------------+------------------------------------- Reporter: | Type: defect painkiller359 | Status: new | Priority: normal Component: | Version: git- undetermined | master Keywords: qsv hwaccel | Blocked By: decoding | Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: When using h264_qsv,hevc_qsv or mpeg2_qsv(haven't tested mjpeg_qsv) decoders sometimes when the decoding starts 1-3 green/null(I'm not sure if they are green or null, ffplay shows them as green in the render) frames appear in the beginning (mostly in between 1-10 frames of the beginning file). I've managed to test almost all the mainstream Intel iGPU's - 3rd gen(i7-3770,HD 4000), 4th gen(i7-4770 & i5-4570,HD 4600), 6th gen(i7-6700k,HD 530), 8th(i7-8700k,UHD 630) and 9th gen(i9-9900k,UHD 630) with latest graphics drivers on Windows. The frequency at which it appears isn't constant, i.e. in 10 tries 1-5 of them will be affected. The test file for h264 which I'm using is this one http://distribution.bbb3d.renderfarming.net/video/mp4/bbb_sunflower_1080p_3… I can attach more test files if required. But I don't think it has something to do with the specified file. This particular log is from a machine with a 4th gen graphics and Windows 10. Tested with latest(as of today) Zeranoe git build.
