e29ab42922 v4l2: Add support of dmabuf
v4l has add a new IOCTL to export a buffer by using dmabuf.
This patch allow to use this new IOTCL if it has been defined in videodev2.h
I introduce a new IO mode (GST_V4L2_IO_DMABUF) to enable this way of working.

59e583b59f v4l2: don't check stride for encoded formats
Don't try to check the stride for encoded formats. Some drivers output
something != 0 and then we don't want to fail on that.

00eed11d6a v4l2: Re-enable prepare-format emission
With the port to gstreamer 1.0 the prepare-format signal stopped being
emitted. Start emitting this again for use in uvch264src.  While there
change the emission to include the caps for extra flexibility instead of
fource, width, height.

527c218533 v4l2src: link against -lrt for clock_gettime()
Need to explicitly link against -lrt for clock_gettime(), which
we don't get in the libs any more, because core moved the
gmodule-no-export-2.0 bit into Requires.Private.

Not required for newer glibc, but for older ones, so check for that.

05d4f81834 v4l2: make gst_v4l2_fill_lists() adapt to kernel 3.3+
When do v4l2_ioctl() with VIDIOC_ENUMINPUT fails on some devices,
kernels before 3.3.0 return EINVAL, but newer kernels return ENOTTY.
This patch make those devices work well on kernel 3.3+.

eecb9a96a6 v4l2: Improve buffer management
Query the amount of available buffers when doing set_config(). This allows us to
configure the parent bufferpool with the number of buffers to preallocate.
Keep track of the provided allocator and use it when we need to allocate a
buffer in RW mode.
When we are can not allocate the requested max_buffers amount of buffers, make
sure we keep 2 buffers around in the pool and copy them into an output buffer.
This makes sure that we always have a buffer to capture into. We also need to
detect those copied buffers and unref them when they return to the pool.

6f707fcbca v4l2: clear DISCONT flag when recycling buffers into the buffer pool
The base class may have set the DISCONT flag on the first buffer pushed
out. We need to clear that when recycling buffers back into the buffer
pool, otherwise we constantly push out buffers with the discont flag
set, which might upset downstream elements, esp. for compressed
formats like mpeg-ts.

4cd9255f0a v4l2src: fix v4l2_munmap() for compressed formats
Make sure we always call munmap() with the same size we called mmap()
with before.

Current v4l2src uses the same structure for VIDIOC_QUERYBUF, VIDIOC_QBUF
and v4l2_munmap calls. The problem is that the video buffer size (length)
may vary for compressed or emulated bufs. VIDIOC_QBUF will change it if
we pass the pointer of a v4l2_buffer. This is why we should avoid using
same variable for mmap and video buffers.

8edb15d12f v4l2src: Use fraction compare util function.
Use the fraction compare utility to compare function, not the

camera configured as 30/1 fps would yield true: 1 == (1 * 20)/30 and not
re-configure the camera. Fixes #656104

6b86b56abd v4l2: fix interlaced set_format configuration
Commit 6c8268dbfd broke recording
from interlaced v4l2 source (e.g. typical tv capture card) since
V4L2_FIELD_SEQ_TB (with fields stored separately) does not map
to currently defined interlaced format (fields stored interleaved).

Besides this mismatch, hardware might quite likely not support or
appreciate this field value, since querying supported formats mapped
_INTERLACED field formats to interlaced=true caps (so the latter should
not be mapped to field value that is not known to be supported).

9dcb60822f v4l2: define V4L2_FIELD_INTERLACED_{TB,BT} if not available in header
Older kernels don't have these, and there's no easy way to check for the
existance of enums that doesn't involve a configure check, so just define
these if the V4L2_CAP_VIDEO_OUTPUT_OVERLAY define is not there, which was
added in the same commit as the TB/BT enum. Fixes compilation on CentOS 5.

bf88547489 v4l2xoverlay: add support to create window
If xoverlay is available, v4l2sink should create a window for the overlay to
display in.

The window automatically tries to make itself as large as possible.
This works well on a small screen, but perhaps should first attempt to use
the size of the video that is played (no scaling).

ff5494046a v4l2sink: special handling for cases gst_buffer_make_metadata_writable()
Special case check for sub-buffers:  In certain cases, places like
GstBaseTransform, which might check that the buffer is writable before copying
metadata, timestamp, and such, will find that the buffer has more than one
reference to it.  In these cases, they will create a sub-buffer with an offset=0
and length equal to the original buffer size.

This could happen in two scenarios: (1) a tee in the pipeline, and (2) because
the refcnt is incremented in gst_mini_object_free() before the finalize function
is called, and decremented after it returns..  but returning this buffer to the
buffer pool in the finalize function, could wake up a thread blocked in
_buffer_alloc() which could run and get a buffer w/ refcnt==2 before the thread
originally unref'ing the buffer returns from finalize function and decrements
the refcnt back to 1!

This is related to issue #545501

c3721534c9 v4l2: fix race condition
The size of the buffer would be zero'd out in gst_v4l2_buffer_finalize()
after the buffer is qbuf'd or pushed onto the queue of available buffers..
leaving a race condition where the thread waiting for the buffer could awake
and set back a valid size before the finalizing thread zeros out the length.
This would result that the newly allocated buffer has length of zero.

We'd prefer to throttle the decoder if we run out of buffers, to keep a bound

alternate between memory alloced by the display driver and malloc'd userspace
memory.

e24cfa7250 v4l2sink: don't render preroll buffers
Most v4l2 drivers will get upset when you queue the same buffer twice in a
row without first dequeueing it.

Rendering of pre-roll buffers can be re-introduced later, but will require
tracking the state of the buffer, and avoiding to re-QBUF if the buffer has
already been passed to the driver.

48a8b53bdd v4l2sink: Improve behavior for shared buffers.
When the decoder is using pad_alloc(), v4l2sink would behave badly if
the number of buffers ('queue-size' property) was not high enough to
account for all the buffers needed by the decoder, and other elements
(such as queues) between the decoder and v4l2sink.  This patch
slightly increases the default number of buffers, and changes v4l2sink
to drop frames rather than return an error in case the number of
buffers is not high enough.

dcea1b2dfc v4l2: sort formats in the right order so that non-emulated formats are prefered
The format list should be sorted from high ranks to low ranks. In the GSList

format a has a lower rank than format b.

Among other things this fixes v4l2src to prefer non-emulated formats
to emulated formats when built against libv4l.
