4 Appendix B SDI Link Status

Run the below command to check the SDI link status and output format of the SDI input source. Run the below command for all media nodes to print media device topology where "mediaX" represents different media nodes. In the topology, log look for the “v_smpte_uhdsdi_rx_ss” string to identify the SDI input source media node.

$ xmedia-ctl -p -d /dev/mediaX

NOTE: Check resolution and frame-rate of "v_smpte_uhdsdi_rx_ss" node.

# xmedia-ctl -d /dev/media0 -p

If the SDI-Rx link has the issue, it appears as below.When SDI source is connected to 4KP60 resolution, it shows:

NOTE: Check resolution and frame-rate of "dv.detect" under "v_smpte_uhdsdi_rx_ss" node.

When the SDI source is not connected, it shows:

Notes for modetest commands:

• Modetest command for 4kp60 Display

$ xmodetest -M xlnx -s 31:3840x2160-60@XV20  -w 31:sdi_mode:5 -w 31:sdi_data_stream:8 -w 31:is_frac:0 

• Modetest command for 4kp30 Display

$ vcu_gst_app /media/card/config/input.cfg

...

• Follow the below steps to switch the SDI-Rx resolution from 1080p60 to 4kp60.
  • Check current SDI Input Source Resolution (1080p60) by following the above-mentioned steps.
  • Run vcu_gst_app for current SDI resolution (1080p60) by executing the following command.

$ vcu_gst_app /media/card/config/input.cfg

Below configurations needs to be set in input.cfg for SDI-1080p60.

Notes for gst-launch-1.0 commands:

• Make sure the SDI-Rx media pipeline is configured for 4kp60 resolution and the source/sink has the same color format. Run below xmedia-ctl commands to set the resolution and format of the SDI scaler node.

When SDI Input Source is NVIDIA SHIELD

NOTE: Make sure NVIDIA SHIELD is configured for 4kp resolution and UYVY8 color format.

When SDI Input Source is ABOX

NOTE: Make sure ABOX is configured for 4kp resolution and UYVY8 color format.
