webcam-capture

I have a simple Python script that captures a webcam using OpenCV . My webcam has the potential to stream 30 FPS, but since my Raspberry Pi isn't powerful enough, I can only read ~ 20 FPS. When running the script, one core of my CPU is maxed to 100%, but the the rest of the cores are untouched, so I am trying to split up the reading into the most threads I can in order to use my CPU to it's maximum potential and easily reach 30 FPS. So is it possible to read webcam frames in parallel? This is my attempt: import numpy as np import cv2 import time from threading import Thread CV_CAP_PROP_FPS = 5

we are using a Raspberry Pi + Python 3.4 + PyGame to capture an image from a specific USB webcam. We use this simple code to capture (it works ok): pygame.camera.init() cam = pygame.camera.Camera(pygame.camera.list_cameras()[0],(1280,720)) cam.start() time.sleep(1) webcamImage = cam.get_image() The problem comes here: we have to convert this webcamImage into a PIL image. We follow this link but unfortunately the function Image.fromstring() not exists anymore. So, we can't do that : pil_string_image = pygame.image.tostring(webcamImage, "RGBA",False) pil_image = Image.fromstring("RGBA",(1280,720
