I want to use Jetson to run AJA KONA HDMI
when I run the test sample

lucas@lucas-desktop:~/aja/ntv2sdklinux_16.1.0.3$ gst-launch-1.0 ajavideosrc mode=4Kp30-rgba input-mode=hdmi nvmm=true ! nv3dsink

Clara Holoscan SDK User Guide indicated that RGBA mode must be used with the ajavideosrc plugin when it is used whth NVIDIA plugins.

so I tried other sink types
eg.

all other sink types shows the same context as above.

How can I solve the problem .

THX!

This seems not this DeepStream forum can support as we do not have the AJA Kona HDMI device, and issue might be related with Clara, suggest to open topic at Latest Healthcare/Clara Holoscan SDK topics - NVIDIA Developer Forums to see if someone can help. Thanks

I will open a new topic at the Forums that u suggested.
Thanks for your reply.
