Wim Taymans 199fab4b06 video-scaler: add video scaler helper object
Add a video scaler object build on top of the resampler. It has
implementation to deal with interlaced video as well as horizontal and
vertical scaling functions.

Wim Taymans b2fd20c416 video: move videoconvert code to video library
Move the conversion code used in videoconvert to the video library
and expose a simple but generic API to do arbitrary conversion. It can
currently do colorspace conversion but the plan is to add videoscale to
it as well.

Jan Schmidt c98f051548 video: Add gst_video_guess_framerate() function
Takes a nominal frame duration and returns a standard
FPS if it matches closely enough (< 0.1%), or else
calculates a framerate that'll do.

Wim Taymans 9a2344c2e5 video: expose gst_video_info_align
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.

Don't do alignment on the palette in videopool

Wim Taymans 04a2610444 video: improve frame_flags
Rename the frame_flags to flags. Because they are flags on the frame object it
does not need the redundant frame_ prefix.
Change the order of the metadata constructor so that the flags come before the
format and dimension arguments.

Sebastian Dröge 91ffe7dd5e video: Clean up interlaced flags and enums
There's a new GstVideoFrameFlags enum now that contains the frame
specific flags only. GstVideoFlags does not contain the TFF/TFF/ONEFIELD
flags anymore because these are strictly frame specific.

Also add fallback to parse these fields from the GstBufferFlags in
gst_video_frame_map() if there's no GstVideoMeta attached to the buffer.

Wim Taymans 21bf4f04f3 video: fix some video formats
Rename the offset field in GstVideoFormatInfo to poffset to avoid confusion with
the offset of the plane in the buffer. The poffset is the offset in the plane
where the first byte of the component data can be found.
Properly implement the COMP_OFFSET calculations.
Fix YV12 and YVU9, simply use the same offsets as the regular I420 and YUV9
variants, we use the plane info to reorder components already.
Improve the unit test.

Wim Taymans 6241ff63f8 video: update interlace caps and docs
Remove interlaced boolean from caps and replace with an interlace-mode enum.
document this new property in the video caps document. With the enum we can
put fields into separate video meta.
Add enum for this interlace-mode in the VideoInfo.
Update the buffer flags.
