24989b53fc video-info: handle interlaced size correctly
Refactor GstVideoInfo init, make function to set default colorimetry.
Call fill_planes after we configure the GstVideoInfo with parameters
from the caps.
The size of the chroma planes for interlaced vertically subsampled
formats needs to be rounded up to 2, we have 2 fields with each
the same anount of chroma lines.

fb3a9d1bc5 video: avoid overflows when doing int operations for size
size is a gsize, so cast the operands to it to avoid overflows
and setting wrong value to the video size.

Includes tests.

e0cfd6e26b video-info: Also check the stride and offset are equal
gst_video_info_is_equal() was not checking if stride and offset
had changed.

6b77971097 video: Fix NV12_64Z32 default offset and size
This was a regression introduced by f52fd7a68, where we started using
the stride to encode the dimensions in tiles. This patch simply updates
offset and size calculation as described in the documentation,
part-mediatype-video-raw.txt.

f52fd7a68b video: Don't use extra plane and componenent for tile format
Instead of using extra plane, we encode the number of tiles in x and y in the stride of
each planes (i.e. y_tiles << 16 | x_tiles) and introduce tile_mode, tile_width and
tile_height into GstVideoFormatInfo structure.

d899e6df5a video: rename NV12T -> NV12_64Z32
Is a bit more descriptive and allows us to add more tiled types
later.

58592a2af3 audio/video-info: Properly initialize the info structures in set_format()
And don't assume in other code that set_format() preserves any fields at
all. These assumptions were already made here for fields that were changed
by set_format().

65732d9c97 audio/video-info: Initialize the complete struct to 0 in the beginning
Instead of only initializing some parts in some code paths. Also
makes it easier to use the reserved bits of the structs later.

b97c711def audio/video: Initialize all {audio|video}info fields
Fixes "Unitialized Scalar Variable" issues reported by Coverity.

Has the added advantage of detecting whether somebody *does* use those
fields (ending up with a invalid address).

8499a0e35a Revert "video: specify/restrict usage of GST_VIDEO_FORMAT_ENCODED"
This reverts commit 5fcdabd907.

Instead of making it impossible to use the ENCODED format we should
just document that it must not be used for capsfeature-less caps.

Also this commit broke API/ABI.

5fcdabd907 video: specify/restrict usage of GST_VIDEO_FORMAT_ENCODED
GST_VIDEO_FORMAT_ENCODED was added to support *extracting* video-related
information (like width, height, framerate,...) from caps.

It is __NOT__ intended to be used as a format field on video/x-raw caps.

5732ced692 video-info: respect stride alignment

fad4589579 Revert "video: respect stride alignment when calculating planes offsets"
This reverts commit 28e1dadbfa.

Incrementing the offset to make the plane aligned causes the image to be
incompatible with what Xv expects. Rather that forcing a memcpy in the
xvimagesink we would like to do adjust the left padding instead.

Expose the gst_video_info_align function that adds padding and does stride
alignment on a GstVideoInfo. Move this previously private function to
video-info.co
Move the definition of the alignment structure to video.h where it can be picked
up by both the bufferpool and the video-info.
