Python bindings for libuvc with super fast jpeg decompression using libjpegturbo (utilizing the tubojpeg api).

• cross platform access to UVC capture devices.
• Full access to all uvc settings (Zoom,Focus,Brightness,etc.)
• Full access to all stream and format parameters (rates,sizes,etc.)
• Enumerate all capture devices with device_list()
• Capture instance will always grab mjpeg conpressed frames from cameras.

Image data is returned as Frame object. This object will decompress and convert on the fly when image data is requested. This gives the user the full flexiblity: Grab just the jpeg buffers or have them converted to YUV or Gray or RGB and only when you need.

The Frame class has caching build in to avoid double decompression or conversion.

import uvc
import logging
logging.basicConfig(level=logging.INFO)

dev_list =  uvc.device_list()
print dev_list
cap = uvc.Capture(dev_list[0]['uid'])
print cap.avaible_modes
cap.print_info()
for x in range(10):
	print x
	cap.frame_mode = (640,480,30)
	for x in range(100):
		frame = cap.get_frame_robust()
		print frame.img.shape
		#cv2.imshow("img",frame.gray)
		#cv2.waitKey(1)
cap = None
