Issues Streaming and Taking Snapshots Simultaneously with OV64B on VOXL2 (Hadron 640 Setup)

[restore]

Hi,
I'm working with a VOXL2 and the FLIR Hadron 640 camera, and I'm trying to stream video from the OV64B sensor while taking snapshots at the same time.

Initially, I attempted to use "en_preview": true along with "en_snapshot": true, but that configuration did not allow me to stream video. I assumed it might be a resolution constraint, so I modified the configuration to use "en_small_video": true and "en_snapshot": true instead.

Now I can stream video, and when I enter the following command:
voxl2:/data/snapshots$ voxl-send-command hires_snapshot
Successfully sent command to /run/mpa/hires_snapshot/control
In the voxl-camera-server terminal, I receive this error:
ERROR: Camera: hires got unknown Command:
However, when I enter:
voxl2:/data/snapshots$ voxl-send-command hires_snapshot snapshot-no-save
Successfully sent command to /run/mpa/hires_snapshot/control
The camera server shows:
------ voxl-camera-server: Camera server is now running
Camera: hires taking snapshot for pipe only (not saving it)
But I’m unable to access the snapshot data, even after running adb pull.
My Questions:
Is it possible to stream and take snapshots simultaneously on the OV64B?

What does the error message “Camera: hires got unknown Command” mean?

How can I access the output of snapshot-no-save if it's not being saved to disk?

Thanks in advance for your help!

When you use voxl-send-command, the format of the arguments is as follows:

voxl-send-command <image-pipe-name> <command>, so when you run voxl-send-command hires_snapshot, you are sending an empty command to the pipe hires_snapshot. The correct usage would be:

voxl-send-command hires_snapshot snapshot

Please try it.

@Alex-Kushleyev thank you! It works now.
