5d456c7adc video-frame: fix height/width assertions
As commit 274984e8 states:
When doing CROP META it is expected that the width and/or height
in the GstVideoMeta is bigger or equal to the caps negotiated size.

afcc0b3c50 video-frame: Mapping a frame with inconsistent values between GstVideoMeta and GstVideoInfo is a bug
It will cause the frame to be initialized with inconsistent values that then
later can cause crashes or any other kind of interesting and hard to debug
bugs.

40a293d44d video-frame: Add GST_VIDEO_FRAME_MAP_FLAG_NO_REF
This makes sure that the buffer is not reffed another time when
storing it in the GstVideoFrame, keeping it writable if it was
writable.

9398207101 videoframe: Initialise GstVideoFrame to zeroes if mapping fails
This should allow for more meaningful errors. Dereferencing NULL
is more useful information than dereferencing a random address
happened to be on the stack.

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.

53605e35f4 video-frame: fix tiled pixel stride
Pixel stride is per component, not per plane. We get the tile mode from
the pixelstride of the TILE component.

052a1d0f1e video: set interlaced flag correctly in frame
We only look at the interlaced buffer flag in mixed mode, in other modes we
always need to set the interlaced flag.

211b8b6004 video-frame: only copy the visible region
Make sure to only copy the visible region instead of assuming that the complete
stride is visible (which is not the case when padding is used).
