#6431: Linux ffmpeg always segfaults using NVIDIA hw decoders/encoders -------------------------------------+------------------------------------- Reporter: bubbleguuum | Type: defect Status: new | Priority: normal Component: | Version: undetermined | unspecified Keywords: nvidia | Blocked By: Blocking: | Reproduced by developer: 1 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary: using NVIDIA hardware decoding features always crashes ffmpeg with a Segmentation fault. How to reprod: - Required: a NVIDIA card (starting with Geforce 600 series) and working NVIDIA binary drivers (reproduced with v375.66, v378.13 and the latest at this time: 381.22) - ffmpeg compiled with NVIDIA support (at least with the h264_nvdec decoder) This can be quickly reproduced using the static ffmpeg 3.3.1 (or git) build from https://johnvansickle.com/ffmpeg/, with either the 32 bit or 64 bit version.

Using -hwaccel cuvid and/or *_cuvid encoders also crash identically. This issue is not GPU specific as I know someone else got it with a different NVIDIA GPU than me. This crash is also mentioned in one of the last comment of this gist page, using a custom build of ffmpeg: https://gist.github.com/Brainiarc7/988473b79fd5c8f0db54b92ebb47387a Could this issue be related to issue #6405 ? Could this issue be specific to static ffmpeg builds ? In any case, this issue makes using NVIDIA acceleration impossible currently on Linux. -- Ticket URL: <https://trac.ffmpeg.org/ticket/6431> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#7002(undetermined:new): reading wav file from a pipe does not obey the probesize setting

#7002: reading wav file from a pipe does not obey the probesize setting --------------------------------------+---------------------------------- Reporter: akantor | Type: defect Status: new | Priority: normal Component: undetermined | Version: 3.3.6 Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | --------------------------------------+---------------------------------- Summary of the bug: It seems that when a .wav file is read from stdin, the codec probe does not finish until is sees >100kB of data, or EOS. Setting the probesize to something smaller doesn't help. How to reproduce: {{{ ffmpeg version: 3.3.2-static http://johnvansickle.com/ffmpeg/ (see log below) built on: gcc 5.4.1 (Debian 5.4.1-11) 20170519 }}} {{{#!bash % (pv -f -c -L 32000 countToTwelve.wav | ./ffmpeg -v 9 -loglevel 99 -i - -analyzeduration 200 -probesize 200 countToTwelve.flac) |& tr '\r' '\n' }}} Any WAV audio will reproduce. The ` (pv -f -c -L 32000 countToTwelve.wav | ... ) |& tr '\r' '\n' ` pipes the 16khz countToTwelve.wav file at realtime into ffmpeg, and prints progress lines like ` 375KiB 0:00:12 [31.4KiB/s] [=================> ] 55% ETA 0:00:09}` Here's the output: {{{ ffmpeg version 3.3.2-static http://johnvansickle.com/ffmpeg/ Copyright (c) 2000-2017 the FFmpeg developers built with gcc 5.4.1 (Debian 5.4.1-11) 20170519 configuration: --enable-gpl --enable-version3 --enable-static --disable- debug --disable-ffplay --disable-indev=sndio --disable-outdev=sndio --cc=gcc-5 --enable-fontconfig --enable-frei0r --enable-gnutls --enable- gray --enable-libass --enable-libfreetype --enable-libfribidi --enable- libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable- libopenjpeg --enable-libopus --enable-librtmp --enable-libsoxr --enable- libspeex --enable-libtheora --enable-libvidstab --enable-libvo-amrwbenc --enable-libvorbis --enable-libvpx --enable-libwebp --enable-libx264 --enable-libx265 --enable-libxvid --enable-libzimg libavutil 55. 58.100 / 55. 58.100 libavcodec 57. 89.100 / 57. 89.100 libavformat 57. 71.100 / 57. 71.100 libavdevice 57. 6.100 / 57. 6.100 libavfilter 6. 82.100 / 6. 82.100 libswscale 4. 6.100 / 4. 6.100 libswresample 2. 7.100 / 2. 7.100 libpostproc 54. 5.100 / 54. 5.100 Splitting the commandline.

Unfortunately, ffmpeg could decode such a stream only by using software decoding at that time. I can't test anymore if that has changed, but if it hasn't changed, it would be nice if this could get some attention. VP9 10 bit is natively supported by Nvidia (since GTX 1050/GT 1030), Intel (since Kaby Lake IGPs) and AMD (since Raven Ridge APUs). -- Ticket URL: <https://trac.ffmpeg.org/ticket/7099> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
