If you call a function that initializes CUDA from an app written in java when you install a recently released version of the NVIDIA driver (378.49) (other versions may also be included) (cuInit, Stack cookie instrumentation code detected a stack-based buffer overrun.) There is a bug that crashes.
This is not a bug in Ocam and applies to all apps that use CUDA.
Please install the latest version of 378.66 or higher.

Click on CODEC menu of OHCAM and click on the external codec menu item.
Check Use External Codec, select the x264vfw codec and click the Settings button.
Based on the x264vfw default setting, change the yellow box in the figure below as shown.
The parts that are changed are as follows.
Preset-Ultrafast (Set to improve encoding speed and can increase file size, but other options will cause more racks.)
Profile-High 4: 4: 4 (Changes to High 444 for lossless encoding as the default profile may lose video quality.)
Keep input colorspace-Maintains the color space of the internally received buffer. (Other options may cause encoding to fail.)
Rate control-Single pass-lossless-Change for lossless encoding.
Press the OK button to apply the setting.
Since the settings are applied to x264vfw64 for 64-bit when recording 64-bit games, run x264vfw-Configure x264vfw64 from the Start menu and set them as shown above.
If you record with the above settings, you will be recording losslessly, where the important part is to change the settings of the video player to play lossless video losslessly.
The following shows how to check the lossless video based on the next pot player.
After launching the next pot player, click Preferences (F5).
In the environment setting window
Click Image-Colorspace / Properties on the left, and then select Convert directly if possible-Change to default output colorspace in the Colorspace group box on the right. (If this setting is not made, the color of the screen will be lost when playing the video even if the recording is lossless.)
Press OK and play the video recorded without loss.
At this time, if you press Ctrl + F1 on the next pot player, the video codec output format must be output in RGB (32 Bits) as shown below.
In addition, the properties below should be identical in the Playback Information-File Information tab as shown in the following figure.
Format profile: High 4: 4: 4 Predictive @ L3 Color space: RGB Color range: Full Matrix coefficients: RGB
Please note that Windows Media Player does not play properly and the preview thumbnail is not displayed in Windows Explorer.
