What to Do If Minecraft Crashes as Soon as You Start Recording with oCam (NVIDIA Graphics Card)
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.

What to Do If the "WASRecord: pAudioClient->Initialize failed. (hr=0x80070005)" Error Occurs
The "WASRecord: pAudioClient->Initialize failed. (hr=0x80070005)" error can occur when microphone permission has been disabled on Windows 10 or later. This happens because oCam does not have the required permission to access the microphone. Below is a detailed explanation of how to resolve this issue.
For oCam to use the microphone properly, microphone access must be enabled in the Windows Privacy settings. Follow the steps below to check and adjust the setting:
1. Open the Windows Start menu and click 'Settings' (the gear icon).
2. In the Settings window, select 'Privacy'.
3. Click 'Microphone' in the left menu.
4. Check whether the 'Microphone access for this device' option is turned on. If it is turned off, click the switch to turn it on.
5. Check whether 'Allow apps to access your microphone' is turned on. If this setting is disabled, apps such as oCam cannot use the microphone. Make sure it is turned on, then save the setting.
After changing the setting, restart oCam and try recording with the microphone again. If the permission has been granted properly, the "WASRecord: pAudioClient->Initialize failed. (hr=0x80070005)" error is likely to be resolved.
If the problem continues, check the microphone device settings themselves in Control Panel > Sound > Recording tab, or try selecting the microphone input source again in oCam's 'Sound' settings. In addition, updating Windows and oCam to the latest version may also help.
