• I have an MJPEG file decoded with the Intel® IPP JPEG encoder [8.1.42291], how can I convert it to MP4 using ffmpeg ? [closed]

  8 mars 2024, par Renan Aragão

  When trying to convert the MJPEG file with ffmpeg, it gives the following error : Output file #0 does not contain any stream.

  


  This is the complete output :

  I try using ipp in python and dotnet, but idon't found sample code. I need convert MJPEG Intel IPP to mp4.

  


• vcpkg error : BUILD_FAILED when "Getting CMake variables for x64-windows"

  24 août 2024, par Rok Benko

  I'm trying to install ffmpeg via vcpkg on Windows by running the following command :

  


  vcpkg.exe install ffmpeg

  


  The installation throws an error when getting CMake variables for x64-windows.

• Can't convert video with cuda after updating ffmpeg

  8 avril 2024, par Peppe

  i've used this command sometimes to convert 4k video into 1080p without problem with tool "ffmpeg batch" and ffmpeg 5.1 ? "2022-08-10-git-8fc7f0fdec-full_build-www.gyan.dev Copyright (c) 2000-2022 the FFmpeg developers built with gcc 12.1.0 (Rev2, Built by MSYS2 project)" :

  this with pre-input "-hwaccell cuvid"

  


  Now if i try to to the same with latest version of ffmpeg (6.1.1) it don't work. I've tried to change the pre-input with "-hwaccel cuda" but still nothing, it give me error "Cannot find a matching stream for unlabeled input pad scale_cuda:default".

  


  If i try to add [v:0] before 'scale_cuda', i get this error (pgs subs error was present also before editing command) :

  of this if I try to use -vf instead of the "filter_complex" :

  Can someone tell me the correct way to do it now with an rtx 4090 ?
