• ffmpeg custom compile options with hardware/software support

  14 mars 2023, par Capitalmind

  My last compile enabled nvidia/cuda but even though I included —enable-nonfree in the configure, I had issues encoding videos, with outputs like :

  


  ffmpeg -hwaccel cuvid -c:v h264_cuvid -resize 1920x1080 -i Input.mkv -c:a copy -c:v h264_nvenc -preset slow -rc vbr_hq -cq 18 Output.mkv

  


  Giving errors like :

  


  ffmpeg -hwaccel cuvid -c:v h264_cuvid -resize 1920x1080 -i /media/zuultux/Video/Movies/Lawrence.of.Arabia.1962.UHD.BluRay.2160p.TrueHD.Atmos.7.1.HEVC.mkv -c:a copy -c:v h264_nvenc -preset slow -rc vbr_hq -cq 18 /media/zuultux/Video/Lawrence.of.Arabia.1962.UHD.BluRay.1080p.TrueHD.Atmos.7.1.HEVC.mkv


  


  [hevc_cuvid @ 0x5624718179c0] Codec hevc_cuvid is not supported.
Stream mapping:
  Stream #0:0 -> #0:0 (hevc (hevc_cuvid) -> h264 (h264_nvenc))
  Stream #0:1 -> #0:1 (copy)


  


  My actual configure reads :

  


  ./configure --enable-nonfree --enable-cuda-nvcc --enable-libnpp --extra-cflags=-I/usr/local/cuda/include --extra-ldflags=-L/usr/local/cuda/lib64


  


  There a heaps of options on Githhub. Can anyone suggest how to include parameters that specifically :

  


  

  • Toggle enable AMD64/Nvidia or non-hardware processing

  


  • All free and non-free codecs, but particularly VC9, H264/265

  


  • Or basically enable as many features as possible !

  


  


  Note I already have ubuntu-restricted-extras installed.

  


  Configuration used compiled correctly but gave errors when using. Several media files selected to test. nvidia-smi command responds NVIDIA-SMI 470.161.03 Driver Version : 470.161.03 CUDA Version : 11.4

  After fixing the problem I thought to share my results on Github. https://github.com/Capitalmind/makeffmpeg

  


• why is this intel hardware accellerated transcoding in ffmpeg not working ?

  1er avril 2016, par Jabb

  I compiled ffmpeg with intel hardware accelleration, but I cannot transcode the simpsons 720p video from http://www.h264info.com/clips.html with success.

  this is the error I get :

  Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height

  and this is the full output from ffmpeg. What could be wrong ?

• LibAV cannot find hardware acceleration but ffmpeg does. compiled using vcpkg [closed]

  28 novembre 2024, par CottonBuds

  I'm new to ffmpeg and I've been specifically using libav as a library for C++. I'm having troubles with libav not finding "qsv" as hardware acceleration even though I compiled ffmpeg with "qsv".

  


  ffmpeg.exe is working normally and can see "qsv" but not my program that uses libav libraries.

  


  I compiled it on Windows using vcpkg.

  


  Here are some screenshots

  


  

  


  Here ffmpeg.exe can see it
when I run this code

output :


  


  it cant see it
Here is my CMakeLists.txt :

  I've been stuck here for weeks
I cant get hardware acceleration to run with my program

  


  EDIT 1

  


  $FFMPEG_LIBRARIES showed me this

  


  optimizedC:/vcpkg/installed/x64-windows/lib/avfilter.libdebugC:/vcpkg/installed/x64-windows/debug/lib/avfilter.liboptimizedC:/vcpkg/installed/x64-windows/lib/avformat.libdebugC:/vcpkg/installed/x64-windows/debug/lib/avformat.liboptimizedC:/vcpkg/installed/x64-windows/lib/avcodec.libdebugC:/vcpkg/installed/x64-windows/debug/lib/avcodec.liboptimizedC:/vcpkg/installed/x64-windows/lib/swscale.libdebugC:/vcpkg/installed/x64-windows/debug/lib/swscale.liboptimizedC:/vcpkg/installed/x64-windows/lib/avutil.libdebugC:/vcpkg/installed/x64-windows/debug/lib/avutil.lib

  


  I dont understand it well but it said on the vcpkg-cmake-wrapper.cmake

  


  if(ON)
  find_package(PkgConfig )
  pkg_check_modules(libmfx  IMPORTED_TARGET libmfx)
  list(APPEND FFMPEG_LIBRARIES PkgConfig::libmfx)
  if(vcpkg_no_avcodec_target AND TARGET FFmpeg::avcodec)
    target_link_libraries(FFmpeg::avcodec INTERFACE PkgConfig::libmfx)
  endif()
  if(vcpkg_no_avutil_target AND TARGET FFmpeg::avutil)
    target_link_libraries(FFmpeg::avutil INTERFACE PkgConfig::libmfx)
  endif()
endif()


  


  So I'm assuming that if it found libmfx it should show on my FFMPEG_LIBRARIES
