Bug Report Worked Great, but only once.

Hi OBS team, I tried the software at the suggestion of a twitch.tv user, and the first time I used it, it was awesome.

However, after successfully broadcasting twice last night (including scene switching and game streaming). Today, I started up the software, and found that many sources no longer work. I can use images, slideshows, and webcams, but text, game, and software sources are invisible, unavailable, and black, respectively.

I've uninstalled, reinstalled, restarted, uninstalled and reinstalled again, tried the beta version, and deleted the appdata a couple of times. This may have to do with my switchable graphics (and being unplugged), but it seems a little strange that text sources don't work.

Any further suggestions?

Here's a thread where someone had a similar issue: viewtopic.php?f=6&t=1318

Basic specs: Sager np9170 (laptop). i7-3720QM, 8GB RAM, ATI 7970m, Win7 x64

That does seem odd...do you think you can post a log?

If your computer (sounds like it's a laptop) has switchable graphics, you have to make sure that both OBS and the game you are capturing are on the same card, and that the card supports DirectX 10. (Note: Many Intel integrated GPUs claim to support DX10, but their DX10 support is incomplete.)

If you can force everything on the 7970m, maybe that will help?

Either way, posting logs will help us figure it out!

==============================================================

To be clear, no diagnostic ever displays the dedicated GPU for this laptop, but I am forcing the 7970. Monitor capture and even text boxes fail to show up, so I don't think this is a DX10 thing.

Also, the 97% frame lag is something that only happens on the first preview. otherwise it varies between 0.00 and 0.07%. One thing of note is that the FPS drops to <20 when trying to capture the monitor, though nothing is displayed. OBS also takes up significant CPU cycles during this time.

Interesting, this log is showing that your 7970m isn't even enabled. You said something about your computer being unplugged? Does it have to be plugged in to use the better graphics card? Or is there a utility you can download from the manufacturer's website that lets you specify which video card to use on which programs?

So here's what I'm thinking.

Clearly, something changed after the first run - something that took a restart to take effect. If it wouldn't be too much trouble, could someone look into what files or registries are changed by OBS?

EDIT: Windows update had queued updates last night, and installed them in the morning. Could this have anything to do with it?

EDITEDIT: There was a .NET framework update. These have messed things up for me in the past.

Nothing to report on the working/not-working end, but after talking to dodgepong on IRC I tried updating my GPU drivers. I am now certain that OBS is using my 7970 and not my intel, as even Kombustor and Afterburner refer to the dedicated GPU as "Intel HD 4000" while reporting the speed and memory of the AMD 7970m.

Here are some tests trying to run game capture on MSI Kombustor running in DX10 mode. I still can't output text, software capture always shows a black screen and drops to 20FPS, and game capture shows a black screen with a mouse (but only if the mouse is changed by the game).
