Sebastian Dröge 0c99ab5806 videoscale: Optimize transform_caps() 
If the second and next caps structures are a subset of the already existing
transformed caps we can safely skip them because we would transform them to
the same caps again.

David Schleef 7c0b702e14 videoscale: Fix ARGB bilinear scaling 
Fixes #648548.  Orc generates bad code for
gst_videoscale_orc_resample_merge_bilinear_u32, so we'll use the
slightly slower two-stage process.  I'd fix Orc, but it's hard to
get excited about fixing a feature that I'm planning to deprecate
and replace.

Alessandro Decina 030f639a8e android: make it ready for androgenizer 
Remove the android/ top dir
Fixe the Makefile.am to be androgenized

To build gstreamer for android we are now using androgenizer which generates the
needed Android.mk files.

Thiago Santos 91ed9290b8 videoscale: Fix assertion on caps fixation 
When fixating caps, from_par should always be initialized
with a fixed value.

In case the fixation is from src to sink pad it was setting
the from par (srcpad par) to a fraction range, this patch initializes
it to 1/1, based on the assumption that missing PAR is 1/1.

Original commit message from CVS:
* gst/videoscale/gstvideoscale.c: (gst_video_scale_transform_caps):
Prefer the given format if it contains something stricter than [1,MAX]
for height or width and only put a structure that requires rescaling
as second. This makes it possible to use videoscale in pipelines where
the source can actually produce the wanted height/width but usually
selects a different one from the requested.
