    Getting following notification on insmod of hdmi.ko
    insmod ti81xxhdmi.ko
    HDMI W1 rev 4.0
    I2C Bus Low?


    when redirecting output to hdmi lcd,
    gstreamer script used is :

    gst-launch filesrc location=sample.mp4 ! qtdemux! h264par
    se !omx_h264dec ! omx_scaler ! v4l2sink device=/dev/video2 userpointer=false min

    Hello,
    On LCD :
    gst-launch --verbose filesrc location=/usr/share/ti/data/videos/dm816x_1080p_demo.264 ! 'video/x-h264' ! h264parse access-unit=true ! omx_h264dec ! omx_scaler! omx_ctrl display-mode=OMX_DC_MODE_1080P_60 display-device=LCD ! gstperf ! 'video/x-raw-yuv,width=(int)800,height=(int)480' ! omx_videosink sync=false display-device=LCD

    On HDMI:

    gst-launch --verbose filesrc location=/usr/share/ti/data/videos/dm816x_1080p_demo.264 ! 'video/x-h264' ! h264parse access-unit=true ! omx_h264dec ! omx_scaler! omx_ctrl display-mode=OMX_DC_MODE_1080P_60 ! gstperf ! omx_videosink sync=false

    Both are using omx_videosink element. They decode the h264 elementary stream.

    On HDMI:

    gst-launch -v filesrc location=/usr/share/ti/data/videos/dm816x_1080p_demo.264 ! 'video/x-h264' ! h264parse access-unit=true ! omx_h264dec ! omx_scaler ! 'video/x-raw-yuv, width=(int)1920, height=(int)1080' ! v4l2sink device="/dev/video1" show-preroll-frame=false sync=false min-queued-bufs=2 userpointer=false


    On LCD:

    gst-launch -v filesrc location=/usr/share/ti/data/videos/dm816x_1080p_demo.264 ! 'video/x-h264' ! h264parse access-unit=true ! omx_h264dec ! omx_scaler ! 'video/x-raw-yuv, width=(int)800, height=(int)480' ! omx_ctrl display-mode=OMX_DC_MODE_1080P_60 !v4l2sink device="/dev/video2" show-preroll-frame=false sync=false min-queued-bufs=2 userpointer=false

    In this case v4l2sink is used.

    Which one?

    What is your use case?

    If you are set  device=/dev/video2 you will see it on LCD but if you are set /dev/video1 it is HDMI.

    Hello,
    Pass this caps: 'video/x-raw-yuv, width=(int)1920, height=(int)1080'

    Of course you shall have a omx_scaler element in this case.

    Hello,

    What is the software release that you are using?

    Are you using EVM or custom board?

    Are yo using the default settings? If you made some changes what are they?

    What you are executing in the console before to start the pipeline?

    Best Regards,
    Margarita

    Hello,

    Can you enable the venc to produce color bar test pattern and see the color bar once hdmi module is loaded ? (To enable HDMI pattern you need to enable #define ENABLE_VENC_COLORBAR_TEST  1 in hdmi.c) by default when the module is loaded you need to see color bar pattern on hdmi 1080p60.)

    Regards,
