b63fc21d22 video: Safe guard info->finfo when mapping a frame 
Not sure how that slept through but that case is possible and leads
to segfaults in any code path of the function right now.

a62c7bd54c Fix use of undeclared core debug category symbols 
libgstreamer currently exports some debug category
symbols GST_CAT_*, but those are not declared in any
public headers.

Some plugins and libgstvideo just use GST_DEBUG_CATEGORY_EXTERN()
to declare and use those, but that's just not right at
all, and it won't work on Windows with MSVC. Instead look
up the categories via the API.

1fb85733f5 video-frame: Fix gst_video_frame_copy() for formats with pstride==0 
v210, UYVP and IYU1 are complex formats for which pixel stride does not really
have a meaning. If we copy width*pstride bytes per line, it's not going to do
the right thing. As a fallback, copy stride bytes per line. This might copy
uninitialized bytes at the end of each line, but at least copies the frame.

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.

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

the pixelstride of the TILE component.

stride is visible (which is not the case when padding is used).
