• 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.

  What does this error mean ? The suggested git pull and vcpkg update didn't solve the error. The directory is up to date.

• 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) :

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

  


• ffmpeg : Unrecognized option 'alpha_quality'

  16 avril 2024, par László Monda

  I want to make transparent videos work in Safari, which doesn't support WebM for this purpose but only H265 with alpha transparency.

  


  According to this post, I used Shutter Encoder, but only some of its versions work for this purpose on Mac.

  


  Instead of using Shutter Encoder on Mac, I want to use ffmpeg on my Linux PC. Shutter Encoder uses the following command in the background :

  


  ffmpeg -threads 0 -hwaccel none -i input.mov -c:v hevc_videotoolbox -alpha_quality 1 -b:v 1000k -profile:v main -level 5.2 -map v:0 -an -pix_fmt yuva420p -sws_flags bicubic -tag:v hvc1 -metadata creation_time=2024-04-14T14:53:08.734684Z -y output.mp4

  


  which yields the following output on my PC :

Error splitting the argument list: Option not found


  


  When googling for "Unrecognized option 'alpha_quality'.", there are no results, which I find very odd.

  


  What's going on, and how can I make ffmpeg work for this purpose without Shutter Encoder ?
