Thank you both

Hi Modalai Team,

I am using a UVC camera and following the UVC streaming guide with VOXL version 3.2.0 and do not have ffmpeg installed by default and the link to download the ffmpeg ipk is broken. What is the recommended path forward for using a UVC camera? Should I use voxl-docker-ffmpeg, build voxl-ffmpeg, or something else?

Thanks

Also here is my current voxl-version:

Hi @James-Strawson,

Thanks for the tip I will try it out!

@Eric-Katzfey Thanks for the explanation, I was not starting the voxl-camera-server before.

When I started the voxl-camera-server, I had my camera configuration include the tracking camera which stopped the voxl-camera-server from starting correctly.

Once I changed my camera configuration with voxl-configure-cameras to "hires only" I was able to start the camera server and then start the voxl-streamer as well.

Hi @Eric-Katzfey,
Thanks for the tip, I installed the 3.2.0-0.3.4-b release and still have the same issue. Also I am not sure what to modify in the voxl-streamer.conf file. I modified line 6 from:

"mpa-camera": "hires_preview" },

to:

"mpa-camera": "hires/preview" },

but I think I am missing something as I am getting the same error message.

Thanks,
Dean

Hey Modalai Team,

I'm trying to use voxl_cam_ros with an M0025 (IMX214) and am not getting good image quality out. Here is an example:

I am able to use voxl-rtsp with a decent output:

I am not getting any terrible errors when launching the ROS node except for

ERROR: The requested frame_id(0) does not exist in the queue.
[ERROR] [20204.856915384]: GetImageData() Unable to get Frame data for id: 0 rc: -2

which is harmless according to this post.

my voxl-version is as follows:

yocto:/# voxl-version 
cat: /etc/modalai/voxl-software-bundle-version.txt: No such file or directory

Hi @Lynn-Koudsi and @Eric-Katzfey,

I am having the same issue as you Lynn where I am getting the error:

yocto:/# voxl-streamer
Using configuration file /etc/modalai/voxl-streamer.conf
closing FDs for client channel 0
ERROR: Couldn't open MPA pipe /run/mpa/hires/preview/

Where is the script where you changed /run/mpa/hires_preview?

Thanks,

Dean
