Can't make GStreamer pipeline work with the latest DVSDK 4.0.0.22 on the OMAP3EVM board

Hello,

Could someone please help me make v4l2 -> LCD gstreamer pipeline work correctly?

I want to see video coming from the composite input on the board's LCD.

To do that I use the following pipeline:

gst-launch -v  v4l2src always-copy=FALSE ! capsfilter caps='video/x-raw-yuv,width=720,height=576' ! TIDmaiVideoSink videoStd=VGA videoOutput=LCD displayStd=V4
L2 resizer=TRUE rotation=90

When I run it I see my input on the LCD but it is shaking, has artifacts, has only black and white colors. Moreover the following messages are appearing in the log:

Any help would be highly appreciated.

 

Thank you,

If I run TI-DMAI-EXAMPLES on the same board I see good looking video on the board's LCD.

    Hello,

    I don't have PAL input to verify the above pipeline but i would recommend using memory optimized pipeline to avoid any memory bandwidth issues. The pipeline you are using is doing memcpy for D1 PAL buffer to display buffer - which will eat lot of CPU cycles.

    gst-launch v4l2src always-copy=FALSE ! 'video/x-raw-yuv,width=720,height=576' ! TIDmaiVideoSink videoStd=VGA videoOutput=LCD contiguousInputFrame=TRUE -v

    Thanks

    Hello Brijesh,

    I've tried your command line and here what I'm getting:

    I also have a question: What is the correct cmem driver parameters for the gstreamer. Assumption is that I want to use DVSDK's codec server as-is.

    # gst-launch v4l2src always-copy=FALSE ! 'video/x-raw-yuv,width=720,height=480'
    ! TIDmaiVideoSink videoStd=VGA videoOutput=LCD contiguousInputFrame=TRUE -v
