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.
