Sony RXO over USB

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.

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

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.

@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

Aaron Bottke

That got it working!!! I really appreciate the help with this!!!
My telemetry quit working though so I have to play with that and get that up and running again.
Thanks!

@Eric-Katzfey

The gphoto-2 seams to be breaking the voxl-vision-px4 system. Any command associated with the voxl-vision-px4 system causes the voxl to kick any adb connection then prevent any from connecting until a power cycle. I can't get both voxl-vision-px4 and gphoto2 installed and running on the same system.

Any thoughts?
Thanks,
