DM6467 Video drivers

Hi All,

I have been ruuning the video loopback sample application provided with the DMAI of DVSDK. (dvsdk_1_40_00_28/dmai_1_10_00_05/packages/ti/sdo/dmai/apps/video_loopback). I came across an issue with the video driver Mentioned are the steps that can reproduce the issue.

    * Start the video loopback application. The video input is set to Composite and the color space is set to YUV422PSEMI.
    * Allow some frames to be captured successfully
    * Pull out the video source from the Video port J13 and then plug it back in after a few seconds.
    * After the video cable is plugged back again the captured image has few lines of garbage data in between the captured frame.

Can anyone throw some light one why the video capture generates some garbage data when the video feed is removed from the video port or stopped momentarily ?

This issue is reproducable with the latest DVSDK 1_40_00_28 and also with DVSDK 1_40_00_21.

Thanks and Regards

Krishna Prabhakaran
