Question: Cannot open include files #66

Closed JeFrederick closed 8 years ago

JeFrederick commented 8 years ago

I followed the compile directions and everything seems to have worked. I can open the sample media player solution and the ffmpegInterop project will build with no errors. When I try adding the project to the application I'm working on though it gives several errors such as Cannot open include file: 'libavformat/avformat.h'. I've looked at the addition library and additional include properties and don't see anything obviously wrong, and any changes I've made haven't changed the errors either. Any suggestions on where I am making a mistake?

Hi @JeFrederick,

If I get you correctly, you built and deploy the FFmpeg libraries, FFmpegInterop project, ran the sample without any issue, and now you are trying to add the FFmpegInterop project to your application project. It sounds like the FFmpegInterop project loses the path to the FFmpeg header files folder e.g. C:\ffmpeg\Build\Windows10\x86\Include

Can you see where the [FFmpegInterop.vcxproj](https://github.com/Microsoft/FFmpegInterop/blob/master/FFmpegInterop/Win10/FFmpegInterop/FFmpegInterop.vcxproj) AdditionalIncludeDirectories point to?

This can be accessed through Visual Studio > FFmpegInterop Project > Properties > General > C/C++ > Additional Include Directories

When you edit the entry, you can see the exact path it is map into in the Evaluated Value window. The evaluated path is where your FFmpeg headers should be in.

Thanks for the help, that was the problem. There was one folder that was missing in the path. It's building properly now.
