• 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.

  


  PS : I opened logs, but I have no idea how to solve the error. I don't understand them.

  As you can see, these audio streams are single channel as each stream is mapping to a unique channel.

  


  I want to combine these audio streams into a aac file such that the output has the channel information retained.

  


  I use the following command to do this :

  


  ffmpeg -i -filter _complex "[0:a:0][0:a:1][0:a:2][0:a:3][0:a:4][0:a:5][0:a:6][0:a:7]join=inputs=8:channel_layout=7.1[aout]" -map "[aout]" -c:a aac output_audio_join.aac

  


  The individual audio streams were having a duration of duration=103.728625 seconds.

  


  The output however is 862.207660 seconds. Why ?
