Resolution problem when using VOXL2-mini USB3 to HDMI adapter
-
Hi @Jskim
I'd like to remind you of this post/exchange we had a few weeks ago:
https://forum.modalai.com/post/13799
So, I'm not sure if this is creating extra issues with your setup unless you did indeed add series caps on the TX lines from VOXL 2 Mini in the MCBL-00022-2.Pretty neat camera, and we want to help you succeed.
I see they run on internal batteries, I was curious why there was no power cord to it.
I see it comes in variations with WiFi. Wonder if maybe you can try an IP based format version instead of UVC?
You can try our WiFI adapter with MCBL-00022-2 as a test.
Like this, but instead of MCBL-00041, use the MCBL-00022-2 (The Alfa dongle only uses USB2).
https://www.modalai.com/collections/accessories/products/wifi-usb-cable-add-onFor the HDMI adapter, I cannot find enough specs in English to see which side provides power (HDMI side, or USB3 side). I would explore further options here to make sure this adapter works with other devices, since we have no experience with it. This item to me is the biggest risk item to your success.
Hope this helps a little bit, and maybe SW team can help you with the other issues.
Thanks!

Thank you so much for your quick reply.1. The HDMI to USB dongle is powered by USB3 from the VOXL2-mini.
2. We have no problem using the TP link wifi dongle on the USB3 port. I have already tested it.
3. We will tell you the results of the test with the arducam USB3.0 camera.
1) You need to check whether the problem is with the USB3.0 port or the streamer or the uvc server.???
2) You can see the voxl2-mini test result in the image below.
*Note: We use USB3 to USb2 conversion, 1280x720 @10fps no problem.
- We tested arducam directly connected to Windows PC USB3 port and there is no problem.

@Jskim I'm sorry but I keep reading through your messages and am finding it hard to understand what you are asking. It sounds like everything works fine up to 1280x720@10fps. But you want at least 1280x720@30fps. What happens when you change 10 to 30? Does voxl-uvc-server not run? Or does it run fine but you see no output?

Thank you for your quick reply.I have a problem with the VOXL2-mini USB3 port.
When I connect a USB3 camera directly to the VOXL2-mini, the camera is recognised but no output.
However, when we change the USB3 to USB2, the camera output is only 1280x720@10fps.-
Correct. we want a minimum of 1280x720@30fps.

voxl-uvc-server is running. But no output is displayed.

A) When you change to 30, there is no output.

@Jskim Ah, okay, that's more clear now. Have you considered the suggestions from @Vinny ? The USB 3.0 port on VOXL2 mini requires some extra capacitance or else it won't work. This is not normally provided by any standard cable and needs to be added in separately. Also, as per the documentation https://docs.modalai.com/voxl-uvc-server/ what output do you see if you enable debug messages? (e.g.
voxl-uvc-server -d) -

Thank you very much for the quick reply.- When I executed the voxl-uvc-server -d command, the screen froze.

We also encountered the problem of 10 FPS limit when trying to stream HD video (1280x720 at more than 10 FPS) using USB3 to HDMI adapter on VOXL2.
@Jskim did you manage to identify/solve the issues somehow?
@milanerd We have added a cable with built in extra capacitance https://www.modalai.com/products/mcbl-00022?variant=49030324060464

@Moderator Thank you. If I understood well, the adapter with added capacitance solved the issue with HD stream at 30 FPS?
