    Hi,

    In fact, the MIPI_Camera library does not have detailed ISP parameters for lens shading, and the effect is not very good. We do not maintain it, and it is not recommended to use this function.

    Hi,

    Yes, when the light is low, the exposure time will be increased to reduce the frame rate. In order to prevent the frame rate from being too low in low light conditions, the firmware has made some restrictions.

    Hi,

    The exposure_auto_priority control seems to control auto and mannual exposure mode.

    If you want to change the framerate, you can try to reduce the exposure time. (exposure_absolute )

    Hello,

    I know what you need. We have a demo,which will throw a data buf to the user when the frame is interrupted. You can get the data buf in the callback function. Maybe you can refer to it. https://github.com/ArduCAM/MIPI_Camera/blob/master/RPI/raw_callback.c

    Feel free to let me know if you need more help. What’s more, can you share your source code?

    I am not very clear about the OpenGL.

    Hello,

    You should ensure if the video1 node exist the resolution you set.

    Please use v4l2-ctl –list-formats-ext -d 1 to check the camera’s detail information.
