[beagleboard] Installing OpenCV for Python3 (cv2) on Debian 8.7

[Daniyal Ansari]

I'm having an issue installing OpenCV for python3 (cv2) on Debain 8.7.

Both commands,

sudo pip install opencv-python
sudo pip3 install opencv-python

return the error,

Collecting opencv-python
  Could not find a version that satisfies the requirement opencv-python
(from versions: )
No matching distribution found for opencv-python

I tried this on many of the other debian versions including the most
updated versions, and versions pre-8.7 and have been unable to make it work
anywhere.

[beagleboard] Unable to run MJPG-Streamer on BeagleBone Blue using C270

[Daniyal Ansari]

Im trying to use mjpg-streamer  on 
my Beaglebone Blue running Debian 8.7 

 (bone-debian-8.7-lxqt-4gb-armhf-2017-03-19-4gb.img.xz).

I am also using 2 C270 logitech webcams but am only trying to stream one at 
a time.

This is the tutorial 

 
I have been trying to follow to install MJPG-Streamer as it uses the 
BB-Black which is the closest tutorial I can find to the BB-Blue.

Here are the commands supplied by the tutorial.


sudo apt-get install g++ curl pkg-config libv4l-dev libjpeg-dev 
build-essential libssl-dev vim cmake

sudo apt-get install imagemagick

wget https://github.com/shrkey/mjpg-streamer/raw/master/mjpg-streamer.tar.gz

tar -xvf ./mjpg-streamer.tar.gz

cd mjpg-streamer

make

sudo make install

./mjpg_streamer -i "./input_uvc.so" -o "./output_http.so -w ./www"


This is my result fom running* ./mjpg_streamer -i "./input_uvc.so" -o 
"./output_http.so -w ./www":*

The only modification I made was to the port that the server runs on where 
I changed it from 8080 to 8090.

Thank you!
