Finally, I tried a test.
I tried changing the video player and the Streamer died immediately.
The conclusion is that the Streamer died even when it was in the foreground.

Thanks,

JS, Kim

@Jskim
[The phenomenon is as follows]
Video Player restart
Video works normally (about 3 minutes)
Streamer is not dead, but the video is frozen.
Looking at the top command contents, Streamer CPU usage is 2.3%.

It stops for 5 minutes and then works normally again (about 1 minute).

It stops again. (CPU usage 1.9%)
Normal operation after 5 minutes
Video freezes after 1 minute (CPU usage 2.3%)

Thanks,

Send streamer error code

Thanks,

Currently alive, but have to wait until the streamer dies. Sometimes he dies.

Hi Ales,

I think the above statement is wrong. Sorry. I inputted it as h265.

There is no problem with h264, but voxl-streamer dies when I use only h265.

Thanks,

Hi!
1. We are using VOXL2 mini.
2. VOXL2 mini version is SDK 1.4.3.
3. Problem with voxl-streamer when using uvc camera h.265 encoder

1. When using "h.265" in voxl-streamer.conf, voxl-streamer service dies.
   There is no problem at all in h.264.
   The player we use is VLC and potplayer.

2. The config settings are as follows.
   [voxl-uvc-server.conf]
   -Resolution = 640x480
   -Frame = 20
   [voxl-streamer.conf]
   Bandwidth = 500000
   encoder = "h.265"

3. The error code is as follows.
   

4) Please tell me the solution.

Hi,

I need help connecting IP camera to Ethernet and HUB add-on.
The conclusion is that GCS does not ping IP camera.
The system configuration is as follows.

Please tell me how to connect from GCS to IP camera.

Thanks,

Thanks for the quick reply.

This is a question about VOXl2 Ethernet Expansion and HUB.

[Model Information]
-system-image: 1.8.02-M0054-14.1a-perf
-hw platform: M0054
-voxl-suite: 1.4.2~beta2

VOXL2 alone works fine and works well when connected to a 5G modem.

[Questions]

1. When using Ethernet Expansion and HUB, it does not work.
   Sometimes it works and sometimes it does not work. It almost never works.
   Once it works, there is no problem even after rebooting,
   but after a day, the same symptom occurs.

In my opinion, the reason it does not work is because VOXL2 power is insufficient.

2. Please tell me the +, - pinmap for the power supplied in the photo.
   I plan to test if it works well when supplying 5V power.
   

If there is a good solution, please let me know.

Thanks,
JS, Kim

@Alex-Kushleyev
I understand. Thanks for the quick reply.

@Alex-Kushleyev
Thank you for your reply. I understand.

[Additional questions]
voxl-streamer CPU Usage increases rapidly. Performance improvement is needed. (H.265 and H.264 are the same.)

[Experiment contents are as follows.]

1. voxl-streamer CPU Usage increases gradually when using UVC camera
2. System configuration

• local : voxl2 + Ethernet Expansion and USB Hub + Wi-Fi dongle
• uvc camera modem : Logotech TOPSYNC
• Remote : Notebook, VLC Viewer

3. Experiment results

• uvc-streamer.conf : bitrate=400000 / h.265, 640x480@30
• Measurement results (after 1 hour)
  => CPU Usage : 31.3% -> 56% -> 61% -> 65% -> -----> 65.8%
  
  
  
  *I tried changing the bitrate, but the symptom is the same.

Thanks,

1. We upgraded VOXL2 as follows.
   system-image: 1.8.02-M0054-14.1a-perf
   hw platform: M0054
   voxl-suite: 1.4.2~beta2

2. However, uvc camera seems to be unrelated to voxl-streamer.
   even if voxl-streamer service is not running, voxl-uvc-server is running.
   

3. uvc camera is not affected by voxl-streamer-h.265. It needs to be confirmed.

JS, Kim

Thank you so much.

Hi,

We are using VOLX2 and VOXL2-mini.
Currently, only H.264 is supported for UVC camera.
Will UVC camera H.265 be supported if I upgrade to SDK 1.4.1?
(voxl-streamer 0.75 / uvc-server 0.17)

Thanks in advance.

@Vinny
Thank you so much.

@Vinny
Please let us know the results of your USB3.0 port test.

Thanks,

@Vinny
I hope you find a solution.
We are already using V2 for VTOL drones, and are planning to use V2-mini for other large-scale projects.

Thank you,

1. We conducted a comparative test on the VOXL2-mini USB3 port HW issue as follows.

1)Test equipment

• VOXL2+5GModem (USB3 port) and VOXL2-mini (USB3 port)
• Arducam 13MP IMX258 OIS Motorized Focus USB 3.0 Camera Module

2)Test results
In conclusion, after removing the VOXL2-mini USB3.0 cable, the same problem appears as a result of testing. (Only 1280x720@10fps is supported.)

a. VOXL2+5GModem (USB3 port)

b. VOXL2-mini (USB3 port)

2. Question

1. When will the board with the VOXL2-mini AC Capacity problem solved be released?
   (We need to use the USB3 port. We need to purchase 3 units right now, but we are unable to purchase them due to the AC Cap issue.)
2. After purchasing VOXL2-mini, is it possible to replace the product if an improved version comes out?

Thanks,

@Jskim

We tested it using a USB30 to USB2.0 cable.

1. 1280x720@10fps is no problem.
2. 1280x720@30fps does not work.

Thanks

@Eric-Katzfey

Sorry, please tell me again how to add capacitors.

Thanks,
