Error: My V4 Miniscope frame buffer is full.

[yqwang1]

Hi I am using miniscope V4 and adding an external UVC arducam high quality camera link is here:
I added the camera in videoDevices.jason using the same qml file (qrc:/behaviorCam.qml) as other default web cameras.
the line I added in videoDevices.jason is below:

"Arducam_IMX477_HQ": {
    "qmlFile": "qrc:/behaviorCam.qml",
    "sensor": "IMX477",
    "frameRate": 30,
    "width": 2560,
    "height": 1440,
    "isColor": true,
    "controlSettings": {
    }
}

When I start the GUI, it can recognize both miniscope camera and arducam; However, when start recording, after a short while, the control panel sending error msg like "Error: My V4 Miniscope frame buffer is full. Frames will be lost!" and I noticed in the miniscope camera window the buffer is 128/128, while the arducam's buffer is below 128.
How could I avoid crash of frame buffer and proper recording? Can i reallocate the frame buffer? Any advice appreciated.
