2 | * s2255drv.c - a driver for the Sensoray 2255 USB video capture device | |
3 | * | |
4 | * Copyright (C) 2007-2008 by Sensoray Company Inc. | |
5 | * Dean Anderson | |
6 | * | |
7 | * Some video buffer code based on vivi driver: | |
8 | * | |
9 | * Sensoray 2255 device supports 4 simultaneous channels. | |
10 | * The channels are not "crossbar" inputs, they are physically | |
11 | * attached to separate video decoders. | |
12 | * | |
13 | * Because of USB2.0 bandwidth limitations. There is only a | |
14 | * certain amount of data which may be transferred at one time. | |
15 | * | |
16 | * Example maximum bandwidth utilization: | |
17 | * | |
18 | * -full size, color mode YUYV or YUV422P: 2 channels at once | |
19 | * | |
20 | * -full or half size Grey scale: all 4 channels at once | |
21 | * | |
22 | * -half size, color mode YUYV or YUV422P: all 4 channels at once | |
23 | * | |
24 | * -full size, color mode YUYV or YUV422P 1/2 frame rate: all 4 channels | |
25 | * at once. | |
26 | * (TODO: Incorporate videodev2 frame rate(FR) enumeration, | |
27 | * which is currently experimental.) | |
