Is there sample code or documentation somewhere, like a getting started guide?

Hi, Really appreciate your work, have managed to get your library working and find that it does display the scenes and sources. Do you have plans on adding to the library? Specifically the ability to record or stream?

I've tried to get the test application and a brand new application working with the libobs-sharp.dll but keep running into this error when attempting to create a scene.

Any ideas on what I'm doing wrong - is it an architecture issue between x32 and x64?

Howdie, I'm trying this as a first-time user with latest Obs Studio (v18.0.1) and getting an access violation early in the run. Most issues I've seen in the repo are referencing much older versions. What is the latest supported version of obs-studio?

Is this comment still relevant? Would you expect recent builds to work without this flag set at OBS build time? #21 (comment)

Many thanks for any pointers you can offer!

We get an error at ResetVideo with the example 'test' program. Dlls are loaded fine. Version: OBS 21.1.2 (64bit, windows)

Unhandled Exception: System.ApplicationException: ResetVideo failed.

What could be the problem?

Hi There,
when i run the Testform.cs it gives me this error?
Unable to load DLL 'obs.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E) Can you please let me know what am I missing?

Starting with 0.16.0, there is a frontend API available. I tried to do a simple mockup, but this is not my forte and could not get passed a simple call to get scene names:

Ref. https://github.com/jp9000/obs-studio/blob/8836592d92284c454f2e2d00b512837d9c53cbe9/UI/obs-frontend-api/obs-frontend-api.h#L47

Sample code

public static class libobsFrontend
{
    public const string importLibrary = "obs-frontend-api.dll";
    public const CallingConvention importCall = CallingConvention.Cdecl;

    [DllImport(importLibrary, CallingConvention = importCall)]
    public static extern string obs_frontend_get_scene_names();
}

During runtime, the call results in Tried to call obs_frontend_get_scene_names with no callbacks!.

The call chain is here to here.

I'm stuck on creating callbacks and have no idea where to begin 🤔.

Trying to add different things to the scene like window capture or video capture and then add filters to those (hardcoded) but I need ids to call these. Where can I find these ids. For example I am trying to add a crop filter like this but it seems that I don't quite get how to use this
var crop = new Filter("crop_pad","Crop", new ObsData("0,0,1920,1080"));

I don't know how to streaming now

Guys, please tell me, how can I run this application? I have already tried everything - nothing comes out - does not see the obs.dll library.

I put the contents of the archive in a folder:
C:\Program Files\obs-studio\build64\rundir\Debug\bin\64bit

What am I doing wrong?

I followed this https://github.com/jp9000/obs-studio to build Obs Studio to get 31 projects but ended up with these 49errors:freetype.lib(bdf.obj) : error LNK2019: unresolved external symbol sprintf referenced in function _bdf_parse_properties

the project text-Freetype2 is throwing errors: error LNK2019: unresolved external symbol sprintf referenced in function _bdf_parse_properties

Can you please tell me troubleshooting steps?

Hello,

Which version of OBS are you using as dll reference ?
I am lunching the app & there is "attemp to write memory" problem.
My actual version is 0.15.4.

Thanks,

Regards,
