Build fails on windows platform.

Hi,
I'm trying to build gdx-video from scratch but it fails while building.
I want to add webm with alpha channel support + some fast forward and seeking features, therefore can't use the existing gdx video release.

Caused by: java.io.IOException: Cannot run program "../../../../src/FFmpeg/configure" (in directory "D:\gdxvideorecursive\gdx-video\gdx-video-desktop\FFmpeg\build\windows64\src\FFmpeg"): CreateProcess error=2, The system cannot find the file specified
        at net.rubygrapefruit.platform.internal.DefaultProcessLauncher.start(DefaultProcessLauncher.java:25)
        ... 8 more
Caused by: java.io.IOException: CreateProcess error=2, The system cannot find the file specified
        ... 9 more

It says configure file not found, but it is present in the ffmpeg src folder.

Hello,

As far as I know, no one has worked on building gdx-video directly on Windows yet. You could try it with MinGW-w64 as described in

• https://trac.ffmpeg.org/wiki/CompilationGuide/MinGW
• https://libgdx.com/wiki/utils/jnigen

If you do not want to experiment and get to work, I can recommend building the native DLL through WSL. You can then use the DLL you created for your tests on Windows.

DLL will work on windows but I primarily wanted to play videos with alpha channel on android but after looking at source for VideoPlayerAndroid ,i guess that's not supported and possible with the native media player.
Any idea how i can play videos with alpha channel on android. I was guessing maybe i could build FFmpeg for android and use the similar decoding script as the desktop version to extract the frames and playback them.
