OBS-Studio with Visual Studio 2013

This may be answered somewhere, but I have not been able to find the answer on the forums.

I'd like to use VS2013 to build and debug OBS-Studio. I have got the older OBS to work, but as I understand it, development is focused on the Multi-platform version.

I've tried to follow the following document: https://github.com/jp9000/obs-studio/wiki/Install-Instructions#windows

However, I can't get find the include folder for x264. I have downloaded the x264 source, as well as the compiled version, but there is no include folder.

Does anyone here use VS2013 to develop OBS-Studio? If not, what IDE are you guys using to code & debug?

Thank you, Jim. The dependencies file really helped me. Building cURL was not happening ;) (It kept screaming that CURL_LIB was not found. I found out that compiling x264 is no fun, either!

Anyhow, I managed to get it to generate the solution file, but did get one error: libdshowcapture/source/capture-filter.cpp is not found.

Perhaps this is just something that was accidentally left in the CMakeLists file?
Or, have I not installed something? The project "win-dshow" is unavailable in VS2013, although the obs-mp does compile and run in debug.

Running Windows 10 (if that makes any difference)

Hi Jim,

I'm running into a similar issue getting things to build.. I'm on Windows 7 and VS 2013, but am getting the similar results... i.e. "Building cURL was not happening ;) (It kept screaming that CURL_LIB was not found."... I tried the link you posted with the pre-built dependencies, but looks like that link is now dead... Any chance you can send a new link for the dependencies...?

Cheers,
Chris

Hi Chris,

The link is not dead, just not complete it seems - just search that site for observed and then downloads is at the top.

This one should work: dependencies

Well you''re not supposed to download the zip from GitHub.

Get Git or a GUI for Git and clone the repo and init the submodules.

I was able to get the obs-studio.sln to manifest using the cmake tool, but the final build step in VS2013 is choking. Anyone know why I"m getting a whole ton of errors like this?

The install docs might need to be updated, but to fix the libdshowcapture error:

1. Go here: https://github.com/jp9000. Looks like Jim's repo.
2. Download libdshowcapture with Git.
3. Copy it to the ../obs-studio/plugins/win-dshow/ directory.
4. Press Generate with CMake again.

Hope this helps for the next guy.

That's not how to do it, if you follow the install instructions you will get the libdshowcapture submodule.

You're correct. The mistake is not doing the git clone recursively. Seems GitKraken doesn't do that by default or I'm missing something. Just install Git command line and run it in the directory where you want it to clone to.

Also, I had to hit the CMake 'Configure' button twice after checking 'COPY_DEPENDENCIES' otherwise it left a 'libavcodec_DIR-NOTFOUND' there. Not sure if that makes a difference, but the message went away. Thanks.
