Question / Help Black Screen for game

painiconico · Apr 20, 2013

Hi, I just started using OBS to broadcast on Twitch.tv but when I added the game screen using game capture, it only show up as a black screen. The game I am trying to capture is Heroes of Might and Magic III Complete in windowed mode.

My speedtest.net results are:

Can someone help?

Some one could correct me if I am wrong but I got the impression that game capture was used for full screen games and because it's in windowed you should be using window capture (software capture). It also could be just that the game doesn't work with game capture.

ThoNohT · Apr 23, 2013

Game capture should also work in windowed mode. From your log I see no reason why it would not work.
But as Cloudwolf said, a good idea would be to try window capture in stead, do remember to turn on aero though when using window capture, or the performance will be horrible.

xdeiog · Apr 23, 2013

I'll go ahead and try to help you, though I'm not that experienced with this program yet!

I had this problem too, although read about it before while using the beta, so luckily I solved my problem in five seconds. Maybe it'll only take you five seconds as well. ;)

The problem I'm thinking of is the Video Device, which was introduced with the latest stable build (and earlier beta builds).
Game Capture must be on the same video device as the game itself. Or in other words, change your video device to your dedicated GPU. ;)

Edit: From looking at your log, I realized you have a laptop with OBS only detecting the internal device.
There are many other problems from laptops, such as here.

Jim said:
If OBS doesn't see it, it probably means you have to force it in a control panel somewhere. Those multi-GPU laptops especially can be really frustrating with that.

Voxletum said:
I believe for the AMD laptops you need to force manually switched graphics in the BIOS, then you will be able to use catalyst control center to force a specific GPU. I don't believe it is possible otherwise, unless you can enable that manual switching in the BIOS. I can't say for sure, I don't have access to such a laptop right now.

I am using window capture to capture my games instead. (it worked.)

Cloudwolf · Apr 29, 2013

Glad to know you figured it out.

In that latest log, you have nothing added to your scene. Make sure you right-click the Sources box and say Add to add a capture method to your scene.

Like so:

A pic says more than 1000 words!!! TY!!! awesomeness :P working great now. i can live stream and all that shi... thanks again

I'm having a problem as well:

It won't show up on applications list and when I do window capture, the dimensions are really off and 3 quarters of the screen I record is black. I can edit scene but then I'd have to click record, see how off the dimensions are, guesstimate how much I should edit the scene by, and try again. Which isn't really working for me. There must be a better way, right?
