[QUESTION] FFmpeg & External dependencies #1953

Closed Barough closed 3 years ago

Barough commented 3 years ago

Haven't been able to build a 'Full' FFmpeg in a while until today and noticed this in the compile log when i had a closer look at it

├ FFmpeg and related apps will depend on OpenCL.dll

├ Compiling FFmpeg with Vapoursynth R52 ├ FFmpeg will need vapoursynth.dll and vsscript.dll to run using vapoursynth demuxers!

That tells me that FFmpeg will require external files to fully work and i found the vaporsynth related files in the 7Zip Vaporsynth archives in the build folder so that's ok then. But there is no trace of a OpenCL.dll file in mabs folders. So where can i get this required file(s) from, if i mite ask?

Theoretically you get the opencl dll from your system32 folder that should be installed by your graphics driver

are the lines of interest

cygpath -S returns /c/Windows/System32 on my system

Thanks :)

But i think it would be great though if required files like the OpenCL.dll files could be made available in the /bin-video/ folders

1480c1 commented 3 years ago

Issue with that is that would make it imply as if you can distribute the OpenCL.dll file, which theoretically, you shouldn't as it would be graphics driver specific
