The "The endpoint device is already in use." Error Appears When Recording Starts
When recording with oCam, you may sometimes encounter problems with sound recording. In particular, when a DAW (Digital Audio Workstation, for example FL Studio) program using Asio4all is running, it may take exclusive control of the system audio, making sound playback or recording unavailable in other programs. As a result, normal sound recording in oCam may become difficult. Below is a detailed explanation of how to solve this problem and record smoothly with oCam.
Asio4all is a driver used for low-latency audio processing and is mainly used in DAW programs. However, when Asio4all is enabled, it takes exclusive control of the system audio, so other programs such as oCam may not be able to capture system sound. To solve this problem, you need to change the audio output device in the DAW program to something other than Asio4all.
The following is how to change the settings:
1. Run the DAW program (for example, FL Studio).
2. In the case of FL Studio, click 'Options' in the top menu, then go to 'Audio Settings'.
3. In the 'Audio Settings' window, check the audio output device and change it from Asio4all to 'Primary Sound Driver' or 'DirectSound'.
4. After saving the settings, play audio in the DAW and then try recording with oCam. The system sound should then be recorded normally.
If you must use Asio4all because of latency issues with a MIDI keyboard, it is best to switch the settings flexibly depending on your working environment. For example:
- When producing music or doing MIDI work in the DAW, use Asio4all to maintain a low-latency environment.
- After finishing your work and when you want to record with oCam, change the playback device in the DAW audio settings to 'DirectSound' or 'Primary Sound Driver' to disable Asio4all.
- After changing the setting, restart the DAW, or reboot the computer if necessary, then confirm that the setting has been applied properly before starting recording with oCam.
Using this method, you can resolve the audio exclusivity issue caused by Asio4all and record system sound smoothly in oCam. If you are working in a DAW and recording at the same time, try switching the audio output device according to the situation to maintain the best environment.

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.
