Hello guys,
I am using a Holoscan pipeline in which I can process three camera streams in parallel.
To include live video streams, I bought an aja kona HDMI. I have installed the drivers according to AJA Video Systems - NVIDIA Docs. The drivers are working. Further, I have installed the AJAControlPanel, AJA ControlRoom and AJA SystemTest. When I attach a HDMI source, I can see the camera input in AJA ControlRoom.
Operating system: Ubuntu 20.04
Grafics card: Nvidia RTX A4500
First tests:
For my first test, I attached two different camera sources (1080p50) to the aja kona HDMI. To import the streams I am using the AJASourceOP and for displaying the HolovizOP:
replayer = AJASourceOp(self, name = “aja”, channel=NTV2Channel.NTV2_CHANNEL1, width = 1920, height = 1080, rdma = True, enable_overlay = False, overlay_rdma = False)
The Question: How can I import multiple camera streams simultaniously and select the different channels.
Changing to another channle like NTVChannel.NTV2_CHANNEL2 shows the same HDMI source but with flickering images.
Wenn I am selecting a different HDMI input at the AJAControlPanel the imported video in the holoscan pipeline changes, but that’s not what I am aming for.
Thanks in advance,
Franziska
