By using a separate variable, first it allows us to sort the lists
of alternates but keep the pointer on the first occurence in the main
playlist (to respect the spec of starting with the bitrate specified
first in the main playlist). It also avoid playing with the lists variable
which should be used to store the list of playlists and not as a pointer
to the current one.
Also fixes a memleak with the g_list_foreach freeing the lists, if it wasn't
pointing to the first element of the list.
Builds with MSVC, not tested in MinGW or anything else. Added
COM handling code, borrowed from dshowvideosink. Moved Linux
specific files to ./linux and added Windows specific files to
./win (generated from IDL files in VS9). Added macros to handle
BSTR and defined bool as BOOL. Fixes#655362.

Basesrc derived classes send an eos when they change state
from paused to ready and that breaks video recordings on camerabin2
as it makes the whole audio branch pads flushing.
Prevent it by using a pad probe that only allows the eos to pass
when it is caused by a stop-capture action.
Adding some additional checks for custom camerabin2 messages
Also improves reliability of the tests by waiting for the preview-buffer message.
This message is generated from the preview pipeline, and might arrive later than the
image/video-done from the main camerabin2 pipeline, the tests need to wait for it even
after getting the image/video-done.
Capsfilters are created on the constructor and their properties can
be set/get from camerabin2's set/get_property functions. The user with
a broken setup would cause assertions when trying to set/get the
capture caps of this camerabin2.
A proper missing-plugin message will be posted when the user tries to
set camerabin2 to READY state.
There does not seem to be a way to retrieve information
about why failure occured, unfortunately.
When failure occurs, do not post a NULL fingerprint tag.

GET_BITS is a macro for gst_bit_reader_get_bits_uint32, which cannot
read more than 32 bits and will fail in this case where it is called
to read 79 bits. Since we want to skip those bits, gst_bit_reader_skip
is more appropriate in this case.
Adds a property to add a custom GstElement to the audio
branch of the pipeline. This allows the user to do custom audio
processing/analysis when recording videos.
Use macros to simplyfy the shading code. Those will ease to add support for
other colorspaces in the future. Add more variants for the shading (left,right,
horiz-in, vert-out, vert-in).
This allows to specify constraints on the compressed downstream caps
by muxers or capsfilters, which will then be forwarded to upstream
and allows video converters to fulfill the constraints.
Code based on Mark Nauwelaerts audio encoder base class.
