Windows phone support

I can see that theora has lib/arm.And I would like to make a build for Windows Phone platform. Is it possible to make a WP build (I need it just for video decoding)? I tried but failed... Details:
I want to compile .s and .asm files with Visual Studio but it keeps reporting huge amount of errors. Is there a way to compile .s and .asm files with Visual Studio? Should I set those files with Custom Build Tools and then some specific parameters or there is another way?

Hi.

The main problem is that Microsoft does not support assembly for ARM so it can't be done. At least for now, with Visual Studio 2015. We tried to do it, but we get an error message directly from MSBuld about ASM not being supported for ARM devices. And there is no binary that would actually translate the ASM into binary.

Keep in mind, this goes only for ASM optimizations. Normal binaries with software decoding work fine.
