0c46c5c3e2 matroska-demux: Actually set detected 3D info into output caps.

video caps.

ec5bc9dccb matroska: Implement basic stereoscopic video support
Implement support for the packed video formats WebM
uses, not all the values that Matroska might use.

In practice, it's really hard to find any samples in the
wild of any.

Supported in both the muxer and demuxer.

d56b11af56 matroska: store stream tags and push as updated
New tags can be found on different parts of the file, so this patch
keeps the stream taglists around for the life cycle of the pad
and adds those new tags as found. Then a new tag is found, the
pad's is marked with a tags changed flag, making the element push
a new tag event on the next check. Before this, we were sending
only the newly found tags, as the element was losing its taglist
when pushing the event.

it is marked as a draft, this part was confirmed to be correct on
IRC), and allows one to determine whether a demuxed stream is
multistream or not, and thus set the multistream caps field
accordingly. In turn, this means downstream does not have to guess.

gst_matroska_parse_take() would return FLOW_ERROR instead of

because buffer is NULL in that case which triggers the error
code path. This made the unit test fail (occasionally at least,

happen only sporadically).

This reverts commit b3aa8755fe.

We are already using the running-time because they were placed on the
buffers with gst_collect_pads_clip_running_time(). Arguably it would be
better to not modify the incomming buffers but collectpads seems to want
to use absolute timestamps from the buffers for finding the best buffer
(this can be changed with a custom compare function..).

b3aa8755fe matroskamux: Use the running time for container timestamps, not buffer timestamps
Buffer timestamps have no real meaning here, and for selecting the next
buffer we already use the running time anyway.

fb14f66696 matroska-demux: Allow a bit more variation when detecting common framerates
Instead of +/- 1ns we allow 2ns now. Due to rounding errors there are
some Matroska files out there with 33.333331ms per frame for 30fps.

6ff7522ba2 matroskademux: Use GstVideoInfo helper to create caps for raw video
This way we do not miss mandatory fields in caps.
At the same time use the gst_pb_utils_get_codec_description helper to
get codec description.

1cb31eeacc matroskamux: Add context flag for WebM
WebM has a couple of specific requirements we need to handle.
Idea is to set this flag once and just rely on mux->is_webm
at run time instead of repeatedly figuring this out from
GST_MATROSKA_DOCTYPE_WEBM (which requires a strcmp()).
