Stefan Sauer 0667b1adf5 textoverlay: keep untimestamped textbuffer until next one
Instead of discarding untimestamped text-buffers immeditely after rendering,
keep them until we receive the next text buffer.

Sebastian Dröge 9ee7398fae pango: Create a new pango context for every subclass
timeoverlay/clockoverlay are setting some global options
on the context that shouldn't be used for the generic textoverlay.

Sebastian Dröge 92d10cbb8c pango: Create a new base class for all the elements
This prevents the ugly hack where the text_sink pad template
was only added for textoverlay but not for the subclasses.

Also makes this work with the core change that made
subclasses inherit the templates of their parent class.

Josep Torra fbc60fc6f4 textoverlay: fix comparison is always false due to limited range of data type
Perform calculation in a temp var with enough room as there's guarantee that
ret will be able to hold the result for example in _blit_AYUV.

Lane Brooks e2150b11ff textoverlay: converted AYUV to use 'A OVER B' alpha compositing
'A OVER B' compositing is explained at
http://en.wikipedia.org/wiki/Alpha_compositing.

Previously, overlaying text on a transparent background image left the
text overlay also transparent. This pipeline shows such an example:

gst-launch videotestsrc pattern=white ! video/x-raw-yuv,format=\(fourcc\)AYUV ! alpha alpha=0.0 ! textoverlay text=Testing auto-resize=False font-desc=60px ! videomixer ! ffmpegcolorspace ! autovideosink

With this patch, text is composited "OVER" the background image and
thus is visible regardless of the alpha of the background image. The
overlay in the above pipeline works after applying this patch.

Stefan Kost 9ac74c59db textoverlay: use a class wide mutex to work around pango reentrance issues
Pango is not reentrant. Use a class wide mutex to protect pange use in
gst_text_overlay_render_pangocairo(). This works reliable in contrast to the
hack in my previous commit.

Rob Clark 54f4aa28c2 textoverlay: fix Cb/Cr inversion for colored text overlays
In case of odd values for xpos or ypos, the division by two in CbCr
plane would result in an off-by-one error, which in the case of NV12,
NV21, or UYVY would cause inversion of blue and red colors.  (And
would be not so easily noticed for I420 as it would just cause the
chroma to be offset slightly from the luma.)

This patch also fixes a silly typo from the earlier patch which
added NV12 support that broke UYVY support.

Mark Nauwelaerts 90a79b4c60 textoverlay: configurable text color and position
Rather than only left, right, top, etc, allow for horizontal and vertical
positioning on a scale from 0 to 1.
Also cater for configuring rendered text color.

Fixes #624920.

Sebastian Dröge 8393257732 Revert "textoverlay: First draw outline text and then the real text"
This reverts commit 60aa09d28c.

First drawing the real text and then the outline produces ugly
text in lower resolutions. The outline line width needs to be somehow
changed relative to the resolution. Fixes bug #602924.
