Adam,

You may need to check if h265parse and v4l2slh265dec are available on your board.

fluster check if v4l2slh265dec is working fine with this command line:

gst-launch-1.0 appsrc num-buffers=0 ! h265parse ! v4l2slh265dec ! fakesink

so if one of them is missing it won't work.

Regards,
Benjamin
