159cf687a1 pluginloader: make sure gst-plugin-scanner is called with the right arch on OSX 
On OSX, GStreamer might be built as a 'fat/universal' binary containing
both 32-bit and 64-bit code. We must take care that gst-plugin-scanner
is executed with the same architecture as the GStreamer core, otherwise
bad things may happen and core/scanner will not be able to communicate
properly.

Should fix issues with (32-bit) firefox using a 32-bit GStreamer core
which then spawns a 'universal' gst-plugin-scanner binary which gets
run in 64-bit mode, causing 100% cpu usage / busy loops or just hanging
firefox until killed.

fd5aa095da pad: Allow tracking of buffers in GST_SCHEDULING debug output 
As GST_SCHEDULING reports when buffers pass through pads due to
gst_pad_push calls, they are a good way of tracking the progress of
buffers through pipelines. As such, adding output of the buffer pointers
to these messages allows tracking of specific buffers, easing debugging.

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.

3882b7f2ed baseparse: tune QUERY_SEEKING response 
Even if we currently do not have a duration yet, assume seekable if
it looks like we'll likely be able to determine it later on
(which coincides with needed information to perform seeking).

a3e55038ac audioparsers: baseparse: Be careful to not lose the event ref 
Don't unref the event if it hasn't been handled, because the caller
assumes it is still valid and might reuse it.

3faccbd29f baseparse: enhancements for timestamp marked framed formats

it is possible to extract duration (if not otherwise provided)
from (near) last frame, and a seek can fairly accurately target the required
position.

Fixes #631389.

a4f5db7088 Revert "baseparse: add skip property" 
This reverts commit b5a3d60363.

Reverting this for now, since no one really seems to remember why this
property exists or what it could possibly be good for. It seems to have
been in the original mp3parse since the beginning of time and was back-
ported from there.

eb73b3e933 baseparse: Don't emit bitrate tags too early 
We wait to parse a minimum number of frames (10, arbitrarily) before
emiting bitrate tags so that our early estimates are not wildly
inaccurate for streams that start with a silence. If the stream ends
before that, we just emit the tags anyway.

While it _would_ be nicer to be specify the threshold to start pushing
the tags in terms of duration, this would introduce more complexity than
this merits.

102ee0cf41 audioparsers: Add bitrate calculation to baseparse 
This makes baseparse keep a running average of the stream bitrate, as
well as the minimum and maximum bitrates. Subclasses can override a
vfunc to make sure that per-frame overhead from the container is not
accounted for in the bitrate calculation.

We take care not to override the bitrate, minimum-bitrate, and
maximum-bitrate tags if they have been posted upstream. We also
rate-limit the emission of bitrate so that it is only triggered by a
change of >10 kbps.
