    Hello,

    OMX/gstreamer with OMX elements do not support multi process content.

    For example if you try to start two different application like:
    gst-launch 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 &
    gst-launch 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 ! fakesink

    It will fail with syslink error.

    But if you execute it:
    gst-launch 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 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_480P_60 display-device=LCD ! 'video/x-raw-yuv,width=(int)800,height=(int)480' ! gstperf ! omx_videosink sync=false display-device=LCD

    it will work.

    For multichannel refer to DVRRDK.
    EZSDK does not support it.
