Hi, I am testing an opencv video capture code on my BBB (running Debian Wheezy: Linux beaglebone 3.8.13-bone79 #1 SMP Tue Oct 13 20:44:55 UTC 2015 armv7l GNU/Linux) but getting a *select timeout error* everytime i run the program. Now i am behind schedule of my final year Iris recognition system Project. (In case you want to know why i am going through this video capture code, it is for tracking the eyes then capture an image that will be processed to obtain an IrisCode.)
I installed opencv 3.0.0 following instructions on http://www.pyimagesearch.com/2015/06/22/install-opencv-3-0-and-python-2-7-on-ubuntu/#comment-393561 , but had to turn off ffmpeg (suggested on one of the forums: http://stackoverflow.com/questions/31663498/opencv-3-0-0-make-error-with-ffmpeg/31818445#31818445 ) after obtaining a compilation errors but firstly i had compiled ffmpeg from source. Below is the Video_Capturing code i tested with; import numpy as np import cv2 cap = cv2.VideoCapture(0) while(True): # Capture frame-by-frame ret, frame = cap.read() # Our operations on the frame come here gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY) # Display the resulting frame cv2.imshow('frame',gray) if cv2.waitKey(1) & 0xFF == ord('q'): break # When everything done, release the capture cap.release() cv2.destroyAllWindows() After running the code i am obtaining the following information (*Note*: The frame is only opening when i run the python script in LXTerminal accessed through tightvnc. It is failing to run through ssh); oot@beaglebone:~/Project/Testing# python Video_Streaming.py (process:1488): Gtk-WARNING **: Locale not supported by C library. Using the fallback 'C' locale.
