What to Do If an Error Occurs When Running the oCam Installer

Using oCam at work or school? A license is required, and it removes all ads, including this window. See the paid version →

When installing or running oCam, you may see an error message like the one below:


"Access violation at address XXXXX in module 'oCamXXXX.exe'. Write of address 00401000"


This error usually occurs when an anti-cheat program such as GameGuard is running. GameGuard uses system resources exclusively to protect the game, and this can interfere with the installation or execution of oCam. To resolve this issue, follow the steps below:


1. Completely close the game that is currently running. When the game closes, GameGuard will also close.

2. To make sure both the game and GameGuard have fully closed, open Task Manager (Ctrl + Shift + Esc) and check whether any related processes, such as GameGuard processes, are still running. If any remain, end those processes manually.

3. After GameGuard has closed, try installing or running oCam again.


By following the steps above, you can resolve the conflict caused by GameGuard and install or run oCam normally. If the problem continues, restart your computer and try installing oCam again without launching the game.

How to Ensure Recorded Videos Can Be Recovered Even If the App Is Force-Closed During Recording

When recording video with oCam, selecting the MKV container from the Codec menu allows the video file to be saved more safely even in unexpected situations. The MKV container offers excellent file stability, so even if the program closes during recording due to various issues, the file will not be corrupted and can still be played normally.

 

For example, even if oCam is force-closed during recording, or if a game suddenly crashes while recording gameplay, the video file saved in the MKV container can still be played normally. This is possible because the MKV format is designed to store data in a highly stable file structure.


On the other hand, if you use the MP4 container, the file may become corrupted and impossible to recover in the same kind of abnormal shutdown situation. For stable recording, using the MKV container is recommended.


However, there are a few things to keep in mind when playing MKV files. If you play an MKV file in Windows Media Player, the seek function, such as jumping to a specific point in the video, may not work smoothly. Playback itself works without a problem, but for better seeking convenience, it is recommended to use an external video player such as PotPlayer. PotPlayer plays MKV files reliably and also supports smooth seeking.


Also, MKV files are not supported by Naver's video upload feature. Since the Naver platform does not allow MKV uploads, you will need to use a platform such as YouTube if you want to share videos on the web. YouTube supports MKV uploads without issues and provides an environment optimized for sharing and playback.


Therefore, if you want stable recording with oCam, the most effective method is to select the MKV container from the Codec menu, use an external player such as PotPlayer for playback, and use YouTube for web sharing.
