NDI HX
Hi, is there a way to get the NDI source HX and put it on a virtual video capture device created with v4l2loopback?
I've tested the source created by NDI tool "NDI Screen Capture" running on my Windows PC and captured on Ubuntu machine by the cmd:
gst-launch-1.0 ndivideosrc ndi-name="PCROBERTOALDA (NVIDIA Quadro P620 1)"
! videoconvert
! "video/x-raw, format=YUY2, interlace-mode=progressive, tune=zerolatency"
! tee
! v4l2sink device=/dev/video0
and all is OK.
But when i try with source created by "NDI Screen Capture HX" it shows these msgs and exits:
Setting pipeline to PAUSED ... Pipeline is live and does not need PREROLL ... Setting pipeline to PLAYING ... New clock: GstSystemClock Got EOS from element "pipeline0". Execution ended after 0:00:10.023522556 Setting pipeline to PAUSED ... Setting pipeline to READY ... Setting pipeline to NULL ... Freeing pipeline ...
There are a lot of NDI HX Camera sources on commerce and i'd like to get them with gstreamer.
Is it possible to decode Ndi sources using hw acceleration of Intel (vaapi) or nvidia (NVDEC) video cards?
Can you help me please?
Thank you.
Can you get a debug log with GST_DEBUG=3,ndi*:9 from the HX source, and attach the log here?
Also please make sure that the NDI name you configure on the source is actually correct. You can use gst-device-monitor-1.0 -f to list all the available ones.
This is the gst-device-monitor-1.0 -f result:

If i use Screen Capture (not HX) from my Windows PC the same command works and i can get the video stream into my virtual device made with v4l2loopback in my Ubuntu.
That looks like a problem with the NDI SDK then, or how it's used here. Without being able to reproduce it myself there's not much I can do about that.
I'm having the same issue.

I'm having the same issue.
This is a different problem and has nothing to do with NDI HX :) If you run gst-device-monitor-1.0 -f you'll see the mistake: the NDI name (and probably URL address) are not matching.
The NDI name that you configure on the sink is always prefixed by the hostname (in uppercase letters) by the NDI SDK. So in your case it would become "YOURHOSTNAME (test)".
Thank you so much. I was also missing sudo before gst-device-monitor-1.0.
