  • ffmpeg - error processing files generated by premier pro 2022

    23 mai 2022, par QRrabbit

    Please help with the error, trying to re-encode the source file produced with prores 4444+alpha. Alpha channel is required in my case.

    


    I've tried two separate options, both are erroring out :

    


    $ ffmpeg -i Input.mxf -vcodec prores_ks -profile:v 4 -y Output.mxf 


    


    I'm getting this output

  • Location of the amd64 compiler in Visual Studio 2022 | Compiling FFmpeg with NVENC

    6 juin 2022, par Gal Grünfeld

    I'm trying to follow Nvidia's guide to compile FFmpeg with nvenc support on Windows and it has a stage to export the path of Visual Studio's 2013 SP2 amd64 compiler to the global path variable of the compilation dev environment :

    


    


    export PATH="/c/Program Files (x86)/Microsoft Visual Studio 12.0/VC/BIN/amd64/" :$PATH

    


    


    They say earlier in the guide that for different versions of Visual Studio different path might be required. I'm trying to use Visual Studio 2022 Community, but don't know where its amd64 compiler directory is.
I also don't know what that VC stands for ("Visual C", maybe, whatever that "Visual" might mean ?).

    


    I found in the installation directory of Visual Studio 2022 a few directories named amd64 but none of them were under one with VC or something similar in its name.
The one I think is the most likely candidate to be the updated compiler is at /MSBuild\Current\Bin\amd64.

    


    If anyone knows, please tell me if if this is the right path, and if not, what is the right path.

    


    Microsoft does offer a version of Visual Studio 2013 Update 2, though (I assume they changed their naming scheme from "service packs" to "updates, which would make it the same software), but it doesn't offer a 64-bit version of it, and I want to compile a 64-bit software - so I assume it doesn't come with one. Please do correct me if I'm wrong, it'd save me needing to use a version of Visual Studio that is different than the one in the guide.
