7c5f5b1b7f v4l2: move capture code to device object
Move the details of how to capture to the device object. Remove the
v4l2src_calls.[ch] files because they are empty now.
Provide two simple methods to get and return a buffer to the device.
Also do a slow copy when the buffer is not from our pool.

d9e61954a1 v4l2: Let the device object manage the pool
Rename start and stop methods to open and close because that is what they do.
After setting the format on the device object, setup the bufferpools. Move this
code from the v4l2src_calls.c file, it is shared between source and sink.
Make new device start and stop method that merges various bits of common code
spread over several files.

398001f20d v4l2: don't store stride in the videoinfo
We want to keep the default strides in the videoinfo. Keep the stride of the

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.

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.

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.

f06b105058 v4l2src: do not try to change device format if it's already correct
This allows set_caps to succeed if caps change in a way that
would not modify the format we're getting from the hardware.
Otherwise if not in NULL state, setting caps would fail
with EBUSY.

With this change, in some cases it's OK to go PLAYING->READY->PLAYING
rather than PLAYING->NULL->PLAYING to avoid a time-consuming close
and reopen of the device.

Fixes #621723

9b9f9d0a2a v4l2src: in negotiate, check for error return from set_caps
Fixes #621723  (partially)

set_caps can fail if the video device is running, in that case
setting its format leads to EBUSY.

If set_caps fails then we will not have set up the buffer pool
(it will be NULL) which leads to a crash when we try to pull
buffers. If we fail the negotiate on set_caps failure, then we
won't go to playing state and won't crash.

This is a small improvement. Of course, a nicer fix would
be to make set_caps work in the case where the format is
unchanged. If the format has changed, failing is
probably correct because we need to close the device
(go to NULL state) in order to set caps.

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.

Use GstPoll to wait for the fd of the video device to become readable before

* sys/v4l2/gstv4l2object.h:
Getting the Class from an instance is not just a matter of casting it to
the class struct but it involves calling G_OBJECT_GET_CLASS on the
instance. Fixes #549784.

Original commit message from CVS:
* sys/v4l2/gstv4l2src.c:
* sys/v4l2/v4l2src_calls.c:
When probing the formats and sizes a camera supports, make
sure the best ones (highest resolution, prefered format)
end up at the beginning of the probed caps and the less
desirable ones at the end.  This is important because the
order within the caps matters for things like fixation and
negotiation, ie. what format is chosen in the end.
With recent kernels, the current probing code will end up
querying the supported sizes from lowest resolution to
highest resolution, adding them to the probed caps in that
order, resulting to v4l2src fixating to the lowest possible
resolution if downstream does not express a size preference.
Also make up a somewhat random ranking of prefered output
formats for the same reason. Fixes #485828.
