What to Do If Minecraft Crashes as Soon as You Start Recording with oCam (NVIDIA Graphics Card)
Using oCam at work or school? A license is required, and it removes all ads, including this window. See the paid version →
In Java-based applications that use CUDA, including oCam, problems may occur when certain NVIDIA drivers are installed. In particular, if NVIDIA driver version 378.49 (or some other versions) is installed, a bug may occur where the app crashes with the error "Stack cookie instrumentation code detected a stack-based buffer overrun" when calling the CUDA initialization function `cuInit`.
This issue is not a bug in oCam itself, but a problem with the NVIDIA driver that affects all applications that use CUDA. Therefore, the same error may occur not only in oCam but also in other CUDA-based Java applications.
To resolve this issue, you need to update the NVIDIA driver to the latest version, 378.66 or later. Follow the steps below to update the driver:
1. Go to the official NVIDIA website (geforce.com/drivers).
2. Select your graphics card model and operating system, then search for the latest driver (version 378.66 or later).
3. Run the downloaded driver installer and proceed with the installation.
4. After the installation is complete, restart your computer and run oCam or another CUDA-based application to check whether the issue has been resolved.
Updating the driver to version 378.66 or later will resolve the CUDA initialization crash issue and allow you to use oCam and other related applications normally. If the problem continues even after installing the latest driver, contact NVIDIA Support or check for the latest version of oCam.

How to Fix the Issue of 7 Days to Die Not Being Detected for Game Recording (Anti-Cheat Related)
When recording a game with oCam, problems may occur if a game with an AntiCheat feature is running. AntiCheat software may block recording software or cause conflicts, which can prevent oCam from working properly. Below is a detailed explanation of how to solve this problem and record games smoothly with oCam.
To resolve problems caused by the AntiCheat feature, you can launch the game without AntiCheat enabled. You can use an option provided by Steam or run a specific game executable directly to bypass AntiCheat. Below are two methods:
Method 1: Launch the game from Steam without AntiCheat
1. Launch the Steam client and select the game you want to record (for example, 7 Days to Die) from your Library.
2. On the game's detail page, click the blue 'Play' button.
3. When the launch options window appears, select the 'Launch Without AntiCheat' option.
4. The game will launch without AntiCheat, allowing normal recording with oCam.
Method 2: Run the game executable directly
For some games, you can disable AntiCheat by running the executable directly from the Steam library folder. For example, in the case of 7 Days to Die:
1. Go to the Steam library path. The default path is `SteamLibrary\steamapps\common\7 Days To Die\`.
2. In that folder, find the `7DaysToDie.exe` file and double-click it to run it.
3. When launched this way, AntiCheat is automatically disabled, and you can record the game in oCam without any issues.
Applying the methods above can resolve conflicts caused by AntiCheat and allow you to record the game smoothly with oCam. However, disabling AntiCheat may cause restrictions in online multiplayer mode, so make sure your recording is intended for offline play or single-player mode. If the problem persists, using the latest game patch or the latest version of oCam may also help.
