Question / Help Assassin's Creed IV: Black screen

[nyanko]

Hi,

I was playing and recording Assassin's Creed IV from a long time. I didn't stream it, just recorded to files with OBS. On Tuesday 17.XII I got still OBS v0.583b, but then some crushes began so I updated it to v0.591b and (without closing OBS) I recorded another session successfully. But the other day OBS sadly started to record black screen instead of the game, it still records audio though. I've checked log file trying to compare it with some old one and I found the difference in one place.

Proper report should look f.e. like this:

23:51:02: Audio Encoding: AAC
23:51:02:     bitrate: 320
23:51:02: Using graphics capture
23:51:02: Scene buffering time set to 400

But now it always shows a warning:

23:41:58: Audio Encoding: AAC
23:41:58:     bitrate: 320
23:41:58: Using graphics capture
Warning -- GraphicsCaptureSource::BeginScene: Failed to inject library, GetLastError = 5
23:41:58: Scene buffering time set to 400

And there is one more thing - there was a new patch update in Assassin's before the failed recording. I hope that the patch didn't brake the game visibility for OBS... Anyway what do you think? If you can help, I will be more than happy.

Here is all the log from today with unsuccessfully record attempt:

Do you have any other overlay programs running, like FRAPS? It seems that you're getting an Access Denied error when trying to hook the game. Are you running OBS as administrator?

 

[nyanko]

So something suddenly started to block OBS's access to the game's picture right? But no other overlay programs running and no new software installed in a few last weaks. I've just tested everything once again as administrator, it's still no vision. I have to mention that another game played in full screen mode is recorded correctly by OBS. Now I'm seriously worried that the latest AC patch is the culprit, but there is no negative signs from other users. Is there something else I can do with OBS?

 

[dodgepong]

There was a new AC4 patch recently? As of when?

 

[Lain]

I just tried it with the latest patch and the latest version of OBS, and didn't encounter any issue. I also have a very similar model of video adapter, the 7950. I can't help but feel something else is going on in this case.

 

[nyanko]

I think the game and Uplay updated in 18.XII, additionally it downloaded new DLC Freedom Cry. Uplay had some "minor bug fixes" in ver 4.2.1. Thank you Jim anyway :) It's good to know how it works on similar hardware.

Okay, gentlemen. Now it seems to everything is working correctly. And that is what I've done: I've uninstalled OBS (it was just simple uninstall, nothing like register clearing or something like that) and after that I've downloaded and installed OBS v0.584b. The game is recording with video :) Maybe something went wrong with my previous OBS update.
