    Dropping frames in 720p using driver 5.1.2 and later

    Posted by Cuttlefish on February 22, 2006 at 7:12 pm

    Hi guys,

    I have been struggling with this for while. I am using my custom app based on directshow interfaces. I can capture 1080i stream without any problems, however when I try to capture 720p input, it always drops about 30% of the frames. And then each sequential 720p capture after drops halve as much as previous capture. Any one have any ideas. My app is based on AmCap example from directshow SDK.

    Thanks
    David Liu

    Hi David,

    I think it’s best you join our developer list for questions relating to the SDK and DirectShow in general.

    Kindly email us at support[at]blackmagic-design.com for more information.
