module or meye.<param>=<value> on the kernel boot line when meye is
statically linked into the kernel). Those options are:
- forcev4l1: force use of V4L1 API instead of V4L2
-
gbuffers: number of capture buffers, default is 2 (32 max)
gbufsize: size of each capture buffer, default is 614400
Private API:
------------
- The driver supports frame grabbing with the video4linux API
- (either v4l1 or v4l2), so all video4linux tools (like xawtv)
- should work with this driver.

Besides the video4linux interface, the driver has a private interface
for accessing the Motion Eye extended parameters (camera sharpness,
Bugs / Todo:
------------
- - the driver could be much cleaned up by removing the v4l1 support.
- However, this means all v4l1-only applications will stop working.
-
- 'motioneye' still uses the meye private v4l1 API extensions.

int videobuf_streamoff(struct videobuf_queue *q);
- int videobuf_cgmbuf(struct videobuf_queue *q, struct video_mbuf *mbuf,
- int count);
So, for example, a VIDIOC_REQBUFS call turns into a call to the driver's
vidioc_reqbufs() callback which, in turn, usually only needs to locate the
The vidioc_streamon() and vidioc_streamoff() functions will be a bit more
complex, of course, since they will also need to deal with starting and
-stopping the capture engine. videobuf_cgmbuf(), called from the driver's
-vidiocgmbuf() function, only exists if the V4L1 compatibility module has
-been selected with CONFIG_VIDEO_V4L1_COMPAT, so its use must be surrounded
-with #ifdef directives.
