DMAI Bug exists a year later...

I had a problem with my DM368 design when the video wasn't hooked up.  After detecting the lack of video and hooking it up, my application would fail to operate properly.  After debugging I found the problem was a bug in DMAI's Capture_detectVideoStd.  If video is not detected the function fails to close the vfpe_capture driver before exiting.  Before posting this bug I decide to search the forum and found this year old bug report.

This is a serious flaw for someone trying to design a stable consumer product.  You can detect and report user error for failing to hook up video, but after rectifying the problem the application will fail on subsequent attempts to start encoding.

    Hello John,

    As Acknowledge by Niclas in previous thread, its indeed a bug. And looks like it got overlooked during recent DMAI development. And like Niclas pointed, DMAI is an opensource project and if you need some fixes then feel free to submit patches or bug and we can commit your patches in SVN repo and pick  up in next DVSDK releases. For now, i've reopend it and will see if we can get fix in next DMAI release. 

    Thanks
