b541208b77 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.

ef5ac986f1 videomixer: Add transparent background option for alpha channel formats 2011-04-01 11:35:26 +02:00
Lane Brooks
69b5aedc58 videomixer2: Add transparent background option for alpha channel formats 
This option allows the videomixer2 element to output a valid alpha
channel when the inputs contain a valid alpha channel. This allows
mixing to occur in multiple stages serially.

The following pipeline shows an example of such a pipeline:

gst-launch videotestsrc background-color=0x000000 pattern=ball ! video/x-raw-yuv,format=\(fourcc\)AYUV ! videomixer2 background=transparent name=mix1 ! videomixer2 name=mix2 ! ffmpegcolorspace ! autovideosink  videotestsrc ! video/x-raw-yuv,format=\(fourcc\)AYUV ! mix2.

The first videotestsrc in this pipeline creates a moving ball on a
transparent background. It is then passed to the first videomixer2.
Previously, this videomixer2 would have forced the alpha channel to
1.0 and given a background of checker, black, or white to the
stream. With this patch, however, you can now specify the background
as transparent, and the alpha channel of the input will be
preserved. This allows for further mixing downstream, as is shown in
the above pipeline where the a second videomixer2 is used to mix in a
background of an smpte videotestsrc. So the result is a ball hovering
over the smpte test source. This could, of course, have been
accomplished with a single mixer element, but staged mixing is useful
when it is not convenient to mix all video at once (e.g. a pipeline
where a foreground and background bin exist and are mixed at the final
output, but the foreground bin needs an internal mixer to create
transitions between clips).

Fixes bug #639994.

 * Improved and simplified negotiation
 * Full QoS support
 * Variable framerate support

d72a2fb6da videomixer: Don't return caps in get_caps() that will be rejected 
This commit basically puts _get_caps() in sync with accept_caps().

If we don't have a master pad OR the master pad caps aren't negotiated
then we just return the downstream allowed caps.

If we have a master pad with negotiated caps, we return those caps
with a free range of width/height/framerate

They are the same as the mm0-mm7 MMX registers and will be overwritten
by the assembly code if gcc doesn't know about the MMX registers.

Note: They're all added to the list of clobbered registers in all cases
and not only when __MMX__ is not defined just to make sure that no other
bugs happen with this code just because some compiler version gets things
wrong.

404e673ac0 videomixer: use 'q' constraint instead of 'r' 
This avoids the "bad register name `%dil'" compilation errors on 32bit where
because of 'r' gcc puts the value in a general purpose register and then tries
to access the lower part as %dil/%sil which is not existing on 32bit. 'q' requests
