cf3f195012 matroskademux: search_cluster should find preceding cluster before target
... since failing this constraint takes search_pos by surprise which might
then end up in an infinite loop.

317d3380bb matroskamux: For audio tracks, take the default duration from the first buffer
... if we don't have any better idea from the caps. This allows writing
SimpleBlocks for a majority of audio streams where the duration of
frames is usually fixed. And as a side effect, allows VLC to play
streams with Opus as it only works with SimpleBlocks currently:

d826c5ad96 matroskademux: improve index memory usage
Re-arrange order of index entry struct members to avoid padding
bytes in the middle of the struct, thus potentially reducing the
overall size of the struct and reducing memory used by the index.
On Linux x86_64 the size goes down from 32 bytes to 24 bytes for
each index entry.

d76bd1913f qtdemux: matroskademux: Ignore repeated seek events
Similar to what was done in adaptivedemux, ignore seek
events we've already handled - such as when they are received
on every srcpad of files with lots of streams.

c950672809 matroskamux: only drop actual streamheader buffers with xiph codecs
With Xiph codecs the stream header buffers are both in the caps and are
usually also at the beginning of each input stream, but it's perfectly
possible that the input stream does not have the stream header buffers
inline in the data. Matroskamux would drop the first N buffers assuming
they're stream headers, but this meant it would drop actual payload data
when the stream didn't contain the stream headers inline. Fix this by
only dropping leading buffers if they're flagged as stream headers. This
fixes issues with streams that are being tapped into after streaming
has started.

5d4c71d76e matroskademux: Fix cluster searching if we search multiple times in one chunk
After finding a cluster id in the byte reader, we skip ahead the reader
position by one further byte to be able to continue searching from there
inside the same chunk if the cluster candidate was a false positive.

We have to accomodate for that additional byte when resuming the search,
otherwise all following pulls are off-by-one for every resume and we run
into an assertion.

Modify the caps string to allow width and height greater than 4096.

b09f478e80 Add support for Meson as alternative/parallel build system
https://github.com/mesonbuild/meson

With contributions from:

Tim-Philipp Müller <tim@centricular.com>
Jussi Pakkanen <jpakkane@gmail.com> (original port)

Highlights of the features provided are:
* Faster builds on Linux (~40-50% faster)
* The ability to build with MSVC on Windows
* Generate Visual Studio project files
* Generate XCode project files
* Much faster builds on Windows (on-par with Linux)
* Seriously fast configure and building on embedded

... and many more. For more details see:

http://blog.nirbheek.in/2016/07/building-and-developing-gstreamer-using.html

Building with Meson should work on both Linux and Windows, but may
need a few more tweaks on other operating systems.

f0ba7a5ca4 matroskamux: Remove suspicious checks for pads being active and linked
We should add all pads, no matter if they are linked or active or not at this
point. Skipping some that are not will cause different behaviour than with

dbb8ec4639 matroskamux: Error out if we start writing data with some pads not having a codec id yet
This can only happen if a) upstream somehow gets around the CAPS event failing
or b) there never being any CAPS event.

The following code assumes that all pads have a codec-id.

eb09829a1c matroskademux: don't hold object lock whilst pushing out headers
matroskademux would take the GST_OBJECT_LOCK in
- gst_matroska_demux_push_codec_data_all()
- gst_matroska_demux_query()

Some parse element such as FLAC checks upstream seekability, and
there is some use cases that matroska-demux is linked to a parse element
(e.g.,FLAC format) without intermediate elements (e.g., queue).
In this case, matroska-demux never returns from _push_codec_data_all()
because the parser can return only after it receives the response to
the upstream query, but that's not going to happen because it's
deadlocked.

Elements must not hold the object lock whilst pushing out events
or data.
