BBB video processing

Hi everyone…my project involves devolping a standalone system for image and video processing… initially i heard Raspberry pi can do multimedia tasks better than BBB… but after exhaustive search through discussion forums i found that pi is not an attractive choice for my needs…

components involved are

camera===>BBB===>Zigbee module…

Power supply <==== portable USB baterry /powercape

working:

-capturing a live video stream using a cam attached to BBB
-processing the captured data(some kind of compressions)
-send the compressed data wirelessly using a zigbee module attached to BBB

my doubts are

  • can BBB capture video streams from a camera?
    -If yes, what are the cams which are economical to buy??
    -can BBB process videos with openCV installed on it??
    -can a Zigbee module be attached to BBB??
    -can i be able to operate BBB with batteries(two no.s) or a portable usb battery ??

since am a beginner in embedded linux platform please kindly suggest me tutorials and books which i can go through to master the use of BBB with openCV and interfacing BBB with Zigbee module.

I am looking forward your views and suggestions which will be greatly helpful for me… thanks in advance.

Hi,

my be these two videos by Deek Molloy will help you ?!?

Thank you… i have already went through those… I am very much concerned about hardware implementations…

  1. BBB has one USB port… my intention is to use portable USB battery
  2. using USB is ruled out, i need some capes
    3.Can i use Zigbee module along with BBB?

1. To get more USB-ports use a hub.
3. Dont know about Zigbee...whats about wifi/wlan?

I want to make a stand alone system…

  1. BBB’s USB will be dedicated to power supply in my design
  2. I should go with HD camera cape from Radiumboards
  3. I specially need Zigbee modules as found in www.logicsupply.com
  4. how to interface all these?

thanking you

Hi,

If you need to power your BBB with a battery, you could consider using a 5V like these:

You may have to build your own USB-DC Barrel jack adapter.

Best,

@José Arrarte yeah thank you :slight_smile:

Forget Zigbee on Linux as these are licensing issues that prevent Zigbee working under Linux. Instead, use 6LowPan which you will find here:

https://github.com/linux-wpan

The code maintainer uses two BeagleBone whites connected to at86rf231 transceivers for his development.

Wouldn’t 802.11 WiFi make more sense than 802.15.4 zigbee or 6lowpan for video bandwidths?

6LowPan is 250kbps so either the frame rate or the resolution will have to be adjusted to make this work. Most video is already compressed and any advance compression will take a big processor to achieve higher levels of compression. For instance, TI use a 8 x DSP and 4 ARM processors to achieve realtime MP4 compression for 1080p video. BBB just won’t have the horsepower.
