RB5 drone streaming from different cameras

MJ

While following instructions provided here
https://docs.modalai.com/Qualcomm-Flight-RB5-sdk-camera-server/
and here
https://docs.modalai.com/Qualcomm-Flight-RB5-streamer/
we managed to get low resolution streaming from camera 3 (Front Hi-res).

Is it possible to get higher resolution camera stream (for example FullHD)?
How to get stream from other cameras, for example camera 2 (Front Tracking)?

sh-4.4# rb5-camera-server-configure 

Would you like to enable the camera service?
This will start all cameras in a background process
Selecting yes will start the service, no will disable the service

1) yes
2) no

Could you advise how to get stream from cam2? Thanks!

@MJ said in RB5 drone streaming from different cameras:

Tracking

Hello,

At the moment the rb5-streamer only streams video at 640x480 at 30fps. In order to achieve a different resolution, a custom gstreamer implementation will have to be used. The rb5-streamer is based off of the code found here.

In order to get streams from other cameras, through rb5-streamer, begin by disabling the camera server for the corresponding camera you'd like to use, and start a new rb5-streamer instance using the -c flag to select the camera index. So for the tracking camera:

systemctl stop rb5-camera-server@2
systemctl disable rb5-camera-server@2
rb5-streamer -c 2

A reboot may be required after stopping and disabling the service

you'll then be able to access the stream at rtsp://VEHICLES_IP:8554/camera2

Regarding the weird systemctl status rb5-camera-server@2 warning messages, I don't believe I've seen those warning messages show up before. Were the After and Requires fields modified in the service file? These are the appropriate values in case it was modified:

After=qmmf-server.service
Requires=qmmf-server.service
