112 Number and size of grab buffers for Video 4 Linux
113 The vast majority of applications should not need more than 2,
114 the very popular BTTV driver actually does ONLY have 2.
115 Time sensitive applications might need more, the maximum
116 is VIDEO_MAX_FRAME (defined in <linux/videodev.h>).
118 The size is set so that the maximum possible request
119 can be satisfied. Decrease it, if bigphys_area alloc'd
120 memory is low. If you don't have the bigphys_area patch,
121 set it to 128 KB. Will you allow only to grab small
