5c9988b759 v4l2object: Add support for YVU420M format
This is a multi-planar format with planes non contiguous in memory. It
is intended to be used only in drivers and applications that support the
multi-planar API.

6c539cbb4a v4l2object: mark jpeg as parsed
Assuming that V4L2 CAPTURE devices always use one buffer per JPEG image, we can
always mark JPEGs provided by a V4L2 element as parsed.

The V4L2 elements require that JPEG images sent to V4L2 OUTPUT devices must
always be parsed.

This is necessary to link a V4L2 CAPTURE device with a V4L2 OUTPUT device
without explicitly marking the stream as parsed or adding a jpegparse into the
pipeline.

63ff99ca8e v4l2: bypass check some transfer types in colorimetry

5980fb76e7 video: Add arbitrary tile dimensions support
In current tile representation, only tiles with power of two
width and height in bytes are supported. This limitation
prevents adding more complex tiles formats.

In this patch, we deprecate tile_ws and tile_hs from GstVideoFormatInfo and
replace if with an array of GstVideoTileInfo. Each plane tiles are then
described with their pixels width/height, line stride and total size.
The helper gst_video_format_info_get_tile_sizes() that depends on the
deprecated API is also being removed. This can simply be removed as it wasn't
in any stable release yet.

7f2fb3b783 v4l2: Reset transfer in gst_v4l2_object_acquire_format()
get_colorspace() checks input caps transfer when mapping V4L2_XFER_FUNC_709
back to V4L2_COLORSPACE_BT2020 and GST_VIDEO_TRANSFER_BT2020_12. After
receiving source change event, decoder will G_FMT and S_FMT again. So need
to reset transfer when acquiring format to avoid using the old transfer.

85b53bb65d v4l2: set default resolution if caps has no such information
Output may attemp to set the width and height to zero values if
caps has no such information, which will cause capture get invalid
dimensions. Then decoder reports negotiation failure.

So need to set default resolution if caps has no such information.
Real values can be set again until source change event is signaled.

522f19e013 v4l2videoenc: Setup crop rectangle if needed
Hantro H1 and Rockchip VEPU2 drivers will pad the width/height to a
multiple of 16. In order to obtain the right JPEG size, the image needs
to be cropped using the S_SELECTION API. This support is added as best
effort since older drivers may emulate this by looking at the capture
queue width/height.

b99ecc78ca Replace gst-i18n-*.h with gi18n-lib.h
GLib guarantees libintl is always present, using proxy-libintl as
last resort. There is no need to mock gettex API any more.

This fix static build on Windows because G_INTL_STATIC_COMPILATION must
be defined before including libintl.h, and glib does it for us as part
as including glib.h.

ceff3e8ff7 v4l2object: Add function to get crop regions from device
Get the current crop bounding region from the V4L2 device so
that it can be provided to applications and used to validate
crop settings. Also make the default crop region available so
that it can be used to reset the crop when appropriate.

Uses the selection API when available with fallback to the crop
API for older kernels.

25f240993c v4l2object: rename crop function to reflect its usage
The gst_v4l2_object_set_crop() is used for removing buffer
alignment padding. Give it a name that better reflects
that usage.  This helps to distinguish from cropping of the
input image (e.g. cropping at the image sensor on a captre
device), which can be  unrelated to the memory buffer padding,
especially if scaling is involved.

2f410f26bf v4l2src: Reset the compose window to the default after setting format
When the size of V4L2 capture or output is changes with VIDIOC_S_FMT,
the device is only required to update the compisition window to fit
inside the new frame size.  This can result in captured data only being
updated on a portion of the frame after a resize.

Update the composition window to the default value determined by the
V4L2 device driver whenever the format is changed to make sure that
all image data is composed to its full size.

Fixes #765

fe56af607b v4l2videodec : refactor the setup process of capture
v4l2videodec do some refactoring so that it can support
dynamic resolution change event.

1.wrap the setup process of capture as a function,
as decoder need setup the capture again when
dynamic resolution change event is received.

2.move the function "remove_padding"

9aaef931bf v4l2: handle 0x0 sizes gracefully
Also ignore 0x0 sizes in the fallback case and assume the size can be
anything between 1x1 and MAXxMAX.

This fixes the case where a width=0, height=0 caps are created. Whith
this patch the caps will contain width=[1,MAX], height=[1,MAX].
