e87cd0a29a shm: Add shm based sink and src
These two elements (shmsink and shmsrc) communicate buffers using POSIX
shared memory. They also communicate the caps. The source currently acts as
a live source and ignores the timestamps coming from the sink. It also does
not transfer the tags.

e5a37377ae mpegtsdemux: Some checks to avoid asserts
gst_mpeg_descriptor_find() expects the description field to be non-NULL.
This fixes a couple of calls where the value being passed is not
verified to be non-NULL first.

Move include directives for gst-libs into GST_PLUGINS_BAD_CFLAGS,
and fix all the Makefiles that use it.  This is so that all the
include directories are added in the proper order: first the
directories in srcdir/builddir, then gst-plugins-base dirs, then
gstreamer dirs.  If the order is wrong, installed headers may be
used instead of local headers and/or uninstalled headers from -base.

90753ceb5e 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.

accurately calculate the min/avg/max bitrates for aacparse.

Note: The bitrate was being incorrectly calculated for ADTS streams
(it's not in the header as the code suggests).

88c1e42567 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.

Adds a new property to qtmux that sets a path to a file to write

might be possible to recover the movie using the qtmoovrecover element.

qtmoovrecover is an element that is also a pipeline. It is not
meant to be used with other elements (it has no pads). It is merely
a tool/utilitary to recover unfinished qtmux files.

In such a situation the output buffer size was not big enough (5*2) to fit the

We now generate the SPS/PPS only once which is much more optimal and we now
know the size of the header to calculate the output buffer size more safely.

f33344ab0c mpeg4videoparse: don't set an invalid framerate.
When fixed_vop_rate is not set we can not set a framerate based on
vop_time_increment_resolution as it would most likely be wrong.
Don't set any framerate on the caps in that case.

774b7b33cc qtmux: Actually use new caps info on renegotiation
Following the previous qtmux commit, this patch tries
to use the new info added to the caps to fill the 'trak'
atom's fields and children atoms. This way qtmux will
use the late added 'codec_data' when h264parse adds
it in the following pipeline:

videotestsrc num-buffers=200 ! x264enc byte-stream=true ! \
h264parse output-format=0 ! qtmux ! \
filesink location=test.mov

0b4c0890a5 qtmux: Do caps renegotiation when it only adds fields
Qtmux can accept caps renegotiation if the new caps is a
superset of the old one, meaning upstream added new info to
the caps. This patch still doesn't make qtmux update any
atoms info from the new info, but at least it doesn't
reject the new caps anymore.

A pipeline that reproduces this use case is:

videotestsrc num-buffers=200 ! x264enc byte-stream=true ! \
h264parse output-format=0 ! qtmux ! \
filesink location=test.mov
