d4ae8ac92f matroskadec: parse stereo mode on decoding
Convert the Matroska stereo format to the Stereo3D format, and add a
Stereo3D side data to the stream.

Bump the doctype version supported.

d92b1b1bab lavf/matroska: Adding support for Opus CodecDelay
In order to represent the codec delay accurately in Matroska, a
new element CodecDelay has been introduced. It contains the
overall delay added by the codec in nanoseconds. This patch adds
support for muxing CodecDelay value in the container.
Matroska spec for CodecDelay element can be found here:

bb47aa5850 opus/matroska: Adding support for DiscardPadding in muxer
Support for end trimming Opus in Matroska is implemented by using
the DiscardPadding container element in the Block data. The last
chunk is stored as a Block instead of SimpleBlock and the
trimming information is stored and used to discard samples that
were padded by the Opus codec. This patch adds support for muxing
DiscardPadding element into the container with appropriate value.
Matroska spec for the DiscardPadding element can be found here:

818ebe930f avformat/matroskadec: add WebVTT support
WebM files now support inband text tracks, as described in the
following specification:

http://wiki.webmproject.org/webm-metadata/temporal-metadata/webvtt-in-webm

The Matroska demuxer now detects the presence of WebVTT tracks,
synthesizing WebVTT packets (having codec id AV_CODEC_ID_WEBVTT) and
pushing them downstream in the normal way.

c5f3cc40e3 matroskaenc: implement CueRelativePosition
This is a minimal change to matroskaenc that implements CueRelativePosition in the output.
Most players will probably ignore this additional information, but it is in the
matroska spec, and it'd be nice to be able to make use of it.

509642b4bd WebM muxer writes WebVTT subtitle track
The Matroska muxer now allows WebVTT subtitle tracks to be written
while in WebM muxing mode.

WebVTT subtitle tracks have four kinds: "subtitles", "captions",
"descriptions", and "metadata". Each text track kind has a distinct
Mastroska CodecID and track type, as described in the temporal
metadata guidelines here:

http://wiki.webmproject.org/webm-metadata/temporal-metadata/webvtt-in-webm

When the stream has codec id AV_CODEC_ID_WEBVTT, the stream packet is
serialized per the temporal metadata guidelines cited above. The
WebVTT cue is written as a Matroska block group. The block frame
comprises the WebVTT cue id, followed by the cue settings, followed by
the cue text.  (The block timestamp is synthesized from the cue
timestamp.)
