    In Directshow Property dialog,External Trigger can not be saved

    I'm using DirectShow interface to grab image from DMK 41BF02 1394 camera. Everything is ok, but the external trigger mark can not be saved in video control property dialog(). Just like this, enable trigger in property dialog, click ok to close dialog, exit program and restart computer, open property dialog again, the trigger mode is disable also. but other parameters such as exposure time, gain, were saved.

    First of all, let me know the driver version you use.

    Secondly: The camera has no memory. That means, settings wont survive a power down and you should *NEVER* rely on any settings, you do not set within your application.

    That means, you must set the properties in your source code. This is the only reliable way. Especially if someone else accesses the camera with different settings....

    The dirver version is v4.1.1.4.
    Ok, If no memory in camera, I will set video parameters in my source code.
    Thank you.
