Sony RXO over USB

@Matt-Goddard Okay, so I assume you are using voxl-vision-px4 to talk with QGC then. You will want to point voxl-libgphoto2 to the IP address of your ground station on the Microhard network, which would be the same IP address that you are sending voxl-vision-px4 to.

Right now it seems as though your voxl-libgphoto2 is attempting to send video to QGC over WiFi, when in reality you are connected to QGC over Microhard.

So, instead of using voxl-libgphoto2 192.168.1.215, you will want to use the same IP address as you are for voxl-vision-px4, which you can find using ifconfig on your ground station or should be in voxl-vision-px4's config file: /etc/modalai/voxl-vision-px4.conf. All Microhard IPs will be in the form 192.168.168.X

@tom This is something we have done already

[tom]

Are you able to open the video stream with a different program like VLC or ffplay?

[Matt Goddard]

We have tried VLC with both Linux and Windows, appears to load it with no video stream.

[Matt Goddard]

@tom is the VOXL streamer apk required in order to use the gphoto2 to stream video?

[tom]

@Matt-Goddard We have two different implementations for gphoto2 on VOXL. voxl-libgphoto2 which is what you are using and we also have voxl-gphoto2 which is a newer version that also uses voxl-streamer. I think I will have you try voxl-gphoto2 now.

Here is the link to the build/install instructions for the newer gphoto2 implementation.

Here is a link to the documentation

You will need to use this in combination with voxl-streamer and here is some documentation for getting that going.

[Matt Goddard]

I will try this now and get back to you. Thanks!

[Matt Goddard]

During the process, we managed to brick the board. Will not boot now..

[tom]

@Matt-Goddard We have some documentation on unbricking here

[Matt Goddard]

Got it, we will order the part and unbrick lol. Thanks for the help!

[Aaron Bottke]

The USB and Serial Debug board arrived today. I unbricked the board and installed gphoto2 and VOXL-streamer. The image below is an error I received after running the voxl-gphoto2 command.

Please advise.

[Chad Sweet]

Have you tried gphoto2 using a Linux machine to make sure this device is supported?

Sony RXO

The RX0 II is on the list, is that what you're using?

[Aaron Bottke]

Yes we are attempting to use the RX0. The image below shows that gphoto2 does detect it on an ubuntu machine.

[Eric Katzfey]

@Aaron-Bottke What happens when you run gphoto2 --capture-preview? Do you get an image?

[Eric Katzfey]

@Aaron-Bottke Also, can you try running voxl-gphoto2 with debugging information enabled and send us the ouput? For example: voxl-gphoto2 -d -v -g

[Aaron Bottke]

Results of gphoto2 --capture-preview on my host machine as follows.

On the VOXL running voxl-gphoto2 -d -v -g yields way to much for me to share here so I will split it up.

voxl-gphoto2 -d below.

voxl-gphoto2 -v yields a lot of messages very quickly.
Output as follows.

voxl-gphoto2 -v yields too many messages for me to upload with a screenshot.
I don't see a way to submit a .txt file but the most interesting part of the output that I see is this.

[Eric Katzfey]

@Aaron-Bottke Okay, thanks! That's very helpful information. It looks like the camera is producing images and voxl-gphoto2 is processing them correctly. So try voxl-streamer and see if you can stream the video. That error message seems to be coming from the gphoto2 library but doesn't seem to be hurting anything.

[Aaron Bottke]

Unless I am missing something in the command this is the result from running voxl-streamer and voxl-gphoto2.

Thanks for all the help.

[Eric Katzfey]

@Aaron-Bottke Documentation on voxl-streamer is here: https://docs.modalai.com/voxl-streamer/

For gphoto2 you will want to look at the gphoto2-mpa configuration in /etc/modalai/voxl-streamer.conf. You can use this configuration record by launching with voxl-streamer -c gphoto2-mpa
