i have an usb analog video converter based on usbtv007 chipset (EASYCAP). I connect on it a PAL analog camera.
It works nearly properly with "mplayer tv://". Video has few half white lines running on image, and around the moving part of the image. The displayed and used driver is V4l2.
If i use opencv with python, the video is really worst with latency in addition. When i use in place an usb webcam with same setup (640x480, 20fps), i get a good video quality.
I supposed it is not due to raspberry speed, and I believe it is a driver issue. But i dont know which driver i have to use, and how to use it with opencv.
Do you have any advice on usb video converter and driver to use with opencv ? Thanks to help me not to be lost anymore.
