Similar to qtdemux.
Tested against other Gst elements and MPV. Note that the later
apparently does not show correct results for flipped values.
In particular the Yaw value seems to get ignored by many clients.

Similar to qtmux, but for mkv and webm containers.
Tested against other Gst elements and MPV. Note that the later
apparently does not show correct results for flipped values.
In particular the Yaw value seems to get ignored by many clients.
Can be tested with:
```
gst-launch-1.0 \
videotestsrc num-buffers=90 ! \
taginject tags="image-orientation=rotate-270" ! \
capsfilter caps=video/x-raw,width=640,height=480,max-framerate=30/1 ! \
videoconvert ! \
queue ! \
vp8enc ! \
queue ! \
webmmux ! \

apparently does not show correct results for flipped values.

In fit-down mode only 1.0 rates are supported, and the element will fit
audio data in buffers to their advertised duration.
This is useful in speech synthesis cases, where elements such as
awspolly will generate audio data from text, and assign the duration of the
input text buffers to their output buffers

Incorrect parsing of these bits meant that we were incorrectly parsing
the VP9 uncompressed bitstream header for some profiles, as the header
is of variable length and format depending on the profile. Amongst
various unintended effects, this caused the width and height from the SS
to be incorrectly parsed and set in the caps.

The matrix multiplication makes some assumption about the element
values to simplify the math with fixpoint values. If this is allowed
for the given matrices is now checked first.
Then the debug output for matrix and a comment have been fixed.

If a new fragment is added with a valid duration but no offset then the start
offset is set later based on the end offset of the previous fragment. At that
point the end offset of this fragment can also be calculated and not doing so
would give the next fragment the same start offset.

Allow sample rate, number of channels and bps to change and in that case update
the caps accordingly.
Also move (non-fatal) validity checks and storing of the header values outside
the actual parsing once we actually know that a valid frame is available.
And also don't warn on the last frame with fixed block size blocking strategy
that the block size has changed: the last frame is allowed to be smaller.

While this specific case is also caught when initializing co_chunk, the error
is ignored in various places and calling into the function would lead to out of
bounds reads if the error message doesn't cause the pipeline to be shut down
fast enough.
To avoid this, no matter what, make sure enough offsets are available when
parsing them. While this is potentially slower, the same is already done in the
non-chunks_are_samples case.
Thanks to Antonio Morales for finding and reporting the issue.
