Has anyone tried this:

https://onion.io/streaming-video-over-wifi/

Any idea about distances and fps/ resolutions achieved?

Would the popular PS3 Eye USB cam with YUYV output work here?

@luz

Really interesting... here is a link for Hanrun model volume purchase, $0.60/unit:

Questions:

1. What does CT stand for? Not "coil turn(s)"?

2. What output pins are used for DC +/- on your HLJ model?

3. Can we do PoE on the Hanrun model too? Same pins?

4. Hanrun looks complete with resistors and caps, so no external components needed, I assume? But your model datasheet seems to miss the resistors and caps?

@Zheng-Han

1. What is the status of the kernel driver for PS3Eye on Omega2?

PS3Eye is not UVC compliant.

1. PS3Eye as you know outputs YUYV, not Mjpeg, so what kind of FPS can you get over Omega2 WiFi over a 10-15m distance, for Mjpeg video streaming at 640*480 frames?

2. PS3Eye has both a mic and speaker, so can we use V4L2 on Omega2 for both video and audio streams?

Sorry if this has been asked before. Can someone provide the links then?

My aim is to do Wifi web streaming from USB cam with mjpeg output, in mjpeg, or h264 or divx if the acceleration is supported.

Btw what kind of WiFi throughput can we expect with the PCB ceramic antenna? The doc only says100m LoS outdoors range.

Interesting info...This Omega2 has a lot of quirks for the $5 advertised.

So a 3rd party Ethernet adapter (i.e., except via the very expensive dock) is not a solution.

So what is this MT7688 built in wired Ethernet support? Somewhere it says the MT has either 1 FE PHY or a 5 port Etherswitch.

@Ken-Conrad

You are right ! Just confused myself.

So the Omega2 itself doesn't have a full USB A port, just the serial data pins.

If you want a "full" USB A port, you will have to supply 5V power externally to any USB A plug then.

QUESTION:

On the Ethernet pins side then, will you need a full Ethernet adapter, or is there a cheaper magnetics only module available to have a "full" fast Ethernet connection on the Omega2 itself?

A bit confusing....

So what are the 5V/ Gnd USB pins on the Omega2 pinout diagram?

If you connect 5V/ Gnd PSU to such pins, can you think of the USB pins, 5V, Gnd, D+ and D- as the 4 pins needed for a host USB ( A) port that can also output 5 V much as a regular host USB port can?

1. A wild thought:

What if Omega2 USB pins could be pre-programmed into slave mode (from default host mode), and a USB plug attached could receive ( not output) power to the USB 5V and Gnd?

Would this fry the Omega2, or somehow help power the board from a USB hub or USB power adapter?

1. So from what I gather, for the USB pinout on the Omega2 board, the way for power out is to attach a 5V supply to the USB power pins, for a regular host USB ( A) port function?

I wonder, with the 3.3 V injection onto the regular 3.3 V power pins as recommended by Onion ( power without dock), what is the voltage/ max current on the USB 5V/Gnd pins?

@Ken-Conrad @WereCatf

Well you could still go the route of 5 to 3.3V PSU set up, use same 5V source to directly power USB cam via its USB power pins, do some soldering etc.

But overall the $5 Omega2 figure is as much hype as for the RPi0 which is still not generally available ! 5V tolerance ( as for ESP) or 5V external ( with onboard 3.3V conversion) OTG USB receptacle would really have helped, but ... both RPi and Omega2 want to sell expensive accessories.

The other interesting board I looked at was OrangePi Zero, plus other OPis. But the WiFi driver on OPi0 isn't available owing to the obscure XR819 wifi chip instead of the standard Realtek ones. The BoM comes to $20 if you include memory, casing, PSU and misc.

Meanwhile Android Boxes fully loaded, very hackable, are down to $24-25 already ! Unless you really want single purpose boards like for $5 Sonoff WiFi controllers featuring ESP8266 or USB cam WiFi webstreaming only.

@Ken-Conrad

"Either use a 5V USB power source at the Omega's micro USB socket,.."

Ahhh, I just remembered this. Where is the Omega2 micro USB socket? Is it directly on the Omega2 itself, since otherwise it defeats the purpose? And is it OTG too?

Onion folks mostly just mix up the chip and the dock functions.
