This is excellent. Many thanks for offering your expertise with this.
The most likely reason for failure is lack of OpenGL context.
If you are using the library, one possibility is to use the latest beta version which includes error logging :
This is well advanced and I don’t expect to make any more changes. I have tried dropping in the relevant files to an existing project and had no problems. If you have trouble, you can quickly change back and I will see what else can be done for debugging.
Once you have the new library files ready, you can start a log :
Then a console will open and reveal any errors. If a console is a problem for OBS you can create a log file :
You can find the log file at : C:>Users>username>AppData>Roaming>Spout
If OpenGL context is the problem, it will show up.
Could you first try this and see what it reveals. If it’s no help I will assist further. You can also send me a private message here to correspond by email.
