Unable to install ffmpeg-concat on windows

Hey,i tried to install ffmpeg-concat as mentioned in the docs,before i tried this using latest versions of node and python i faced the same error, after going through the closed issues as suggested by author in one of those closed issues,i have uninstalled the latest node version and installed node-8 and python 2.7 , still i'm getting the following errors. .

here are the steps i have followed to install ffmpeg-concat

npm install --global --production windows-build-tools npm install --global node-gyp setx PYTHON "path\python27\python.exe" npm install -g ffmpeg-concat.

Just to clarify, are those errors or warnings? They seem like warnings.

Could you please paste the entire (or at least the most relevant) output as a text comment?

Thanks @raghuv9

I noticed that your machine is 32bit (ia32). As such, I don't believe this library has dll files for 32 bit Windows: https://github.com/stackgl/headless-gl/tree/master/deps/windows

I'm actually surprised to see that nodejs is able to run on 32bit platforms (all other platforms are 64bit only)! I don't have a ton of development experience on Windows, so unfortunately, I can't be of much help. I don't know where the 64bit library files in this library originally came from.

The only thing I can think of is following instructions on building OpenGL, and copying the produced 32bit libEGL.dll and libGLESv2.dll files into the deps/windows directory. But I can't help you with that :(

A possibly quick trick that might work: You could open the Google Chrome install folder and look for libegl.dll, libglesv2.dll inside there, and then copy those files to the headless-gl deps folders.

Otherwise, you could try building Angle separately (more complicated), and copying the dll / lib files over: https://chromium.googlesource.com/angle/angle/+/HEAD/doc/DevSetup.md
