Streaming 4K video from Qualcomm RB5 drone

[Cody Graham]

I am interested in this as well. I'm actually interested in recording as opposed to streaming at the short term, but both are going to be useful. I've been recording with gstreamer using the following command:

gst-launch-1.0 -e qtiqmmfsrc camera=3 name=tracker ! video/x-h264,format=NV12,width=640,height=480,framerate=30/1 ! queue ! h264parse ! mp4mux ! filesink location=output.mp4

While that has worked, it's only recording 640x480. But if I try to record any higher of a resolution, the program ends very quickly, and no frames are recorded. I'm unsure why a resolution higher than 640x480 is causing any issues.

@Cody-David-Graham Yes, we also see this issue and are working to come up with a solution ASAP.

Hi DevTeam, Is there any update on streaming 4K video from QRB5? Thank you.

[Eric Katzfey]

@kitkatSG Yes, we have enabled most resolutions in that sensor now and are preparing a release to address this issue.

Hi @Eric-Katzfey,
Is there any update from Dev Team on streaming 4K video from QRB5 drone?
Thank you.

@kitkatSG Sorry for the delay. We continue to find issues with the release and are all working diligently to resolve them as soon as possible. Thank you for your patience!

As a backup solution, we mount a 4K USB camera and successfully stream 4K video via GStreamer to QGC. But the video is shaky when flying drone (streaming video is OK with a stationary drone). @Eric-Katzfey Do the Tech Team have any suggestions on:

• Stabilizing the 4K streaming video with GStreamer via software?
• Any suggested 3-axes gimbal that we can buy and mount on the QRB5 Drone in order to stabilize the camera?

Thank you.

@kitkatSG There's generally a couple of different possible video distortions. One is due to the vibration from the motors. If you mount the camera on rubber dampeners you can remove most of this type of distortion. But of course the drone is moving and that causes motion as well. We don't have a recommendation on gimbal but would love to hear if you are able to find something that works well for you. And we have not tried any GStreamer stabilization software so cannot comment on that, but would love to hear if you find a software stabilization solution that works.
