* s2255drv.c - a driver for the Sensoray 2255 USB video capture device
|
|
*
|
|
* Copyright (C) 2007-2014 by Sensoray Company Inc.
|
|
* Dean Anderson
|
|
*
|
|
* Some video buffer code based on vivi driver:
|
|
*
|
|
* Sensoray 2255 device supports 4 simultaneous channels.
|
|
* The channels are not "crossbar" inputs, they are physically
|
|
* attached to separate video decoders.
|
|
*
|
|
* Because of USB2.0 bandwidth limitations. There is only a
|
|
* certain amount of data which may be transferred at one time.
|
|
*
|
|
* Example maximum bandwidth utilization:
|
|
*
|
|
* -full size, color mode YUYV or YUV422P: 2 channels at once
|
|
* -full or half size Grey scale: all 4 channels at once
|
|
* -half size, color mode YUYV or YUV422P: all 4 channels at once
|
|
* -full size, color mode YUYV or YUV422P 1/2 frame rate: all 4 channels
|
|
* at once.
