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.

What to Do If the "Failed to av_image_alloc" Error Appears When Starting Recording
While using oCam, this error message may appear in very rare cases. This error is usually caused by insufficient available memory on the Windows system. Below is a detailed explanation of how to resolve this issue.
The first solution is to reduce memory usage. To do this, close other programs that are currently running to free up system memory, then try recording again with oCam. The more programs you have running, the more system resources are divided, so closing unnecessary programs can help reduce memory shortage issues.
The second method is to reduce the size of the recording area. If the recording area is set too large, memory usage can increase. In oCam, try reducing the recording area using the mouse or shortcut keys (such as Shift + arrow keys) before recording. This can lower memory usage and help prevent the error.
Third, this issue can also occur if oCam's video resolution setting is too high. For example, if recording is set to a high resolution such as 8K, it can place a heavy load on system memory. To fix this, follow the steps below:
1. In the oCam main window, click 'Tools' in the top menu, then select 'Options'.
2. In the Settings window, go to the 'Recording' tab.
3. In the 'Resize' section, find the 'Video Resize' option and check the currently configured resolution.
4. Change the resolution to a lower value, such as 1080p or 720p, and save the setting.
5. Restart oCam and try recording again.
Applying the methods above can resolve errors caused by insufficient memory and allow you to record more reliably in oCam. If the problem continues, consider checking your system's memory status or updating oCam to the latest version.
