f10435580f v4l2: Include sys/ioctl.h for the V4L ioctl requests
Old videodevice2.h kernel headers used ioctl stuff without
including ioctl.h, making compilation fail on older systems.

Note: Including ioctl.h here is only a workaround for old kernel
headers, should be removed once everybody has new enough headers.

Fixes bug #597867.

00ffa9c2dd v4l2src: add a function pointer for get_frame function and optimize a bit
Use a function-pointer for mmap/read, as this can't change during capture. Also
sprinkle a few G_LIKELY/UNLIKELY to improve the error-less code path.

1a945a32cc v4l2: log buffer copies on queue underrun in perf category
v4l2src has a slow path where it does buffer-copies when it runs out of queued
buffers. Log this to performance category to help monitoring it.

10d41286d5 v4l2src: fix 'hang' with some cameras caused by bad timestamping if no framerate is available
For cameras/drivers that don't support e.g. VIDIOC_G_PARM we'd end up without
a framerate and would try to divide by 0, causing run-time warnings and all
frames to be timestamped with 0, which makes sinks that sync against the clock
drop them, causing 'hangs' (observed with the pwc driver and a Logitech QuickCam
Pro 4000). So if we do not know the framerate, simply don't adjust the
timestamps. Fixes #591451.

99e2ac121d v4l2sink: change where buffers get dequeued
It seems to cause strange occasional high latencies (almost 200ms) when dequeuing buffers from _buffer_alloc().  It is simpler and seems to work much better to dqbuf from the same thread that is queuing the next buffer.

f19cfbda96 v4l2: Add v4l2sink element
This also does the following changes:
(1) pull the bufferpool code out into gstv4l2bufferpool.c, and make a
    bit more generic so it can be used both for v4l2src and v4l2sink
(2) move some of the device probing/configuration/caps stuff into
    gstv4l2object.c so it does not have to be duplicated between
    v4l2src and v4l2sink

Fixes bug #590280.

085f87d85f v4l2: Fix v4l2src on OpenSolaris
The v4l2 driver for USB webcams on OpenSolaris does not support select()
calls. Detect when select() fails, and skip polling the device afterward,
which restores the pre 0.10.14 behaviour on OpenSolaris.

b6755a7000 Wait for a frame to become available before capturing it
Use GstPoll to wait for the fd of the video device to become readable before
trying to capture a frame. This speeds up stopping v4l2src a lot as it no
longer has to wait for the next frame, especially when capturing with low
framerates or when the video device just never generates a frame (which seems a
common issue for uvcvideo devices)

Fixes bug #563574.
