0288ee24e9 ttml: correctly implement lineHeight behaviour
The specified behaviour in TTML when lineHeight is "normal" is different
from the behaviour when a percentage is given. In the former case, the
line height is a percentage (the TTML spec recommends 125%) of the largest
font size that is applied to the spans within the block; in the latter
case, the line height is the given percentage of the font size that is
applied to the block itself.

The code doesn't correctly implement this behaviour; this patch fixes
that.

f28df30a8b ttmlrender: apply correct line height to blocks with multiple text sizes
In TTML, the height of every line in a block is determined by lineHeight
and fontSize style attributes, and should be the same for each line in
that block, regardless of whether different sized text appears on
different lines. Currently, a single PangoLayout is used to lay out all
the text in a block; however, pango will vary the line height in a
layout depending on the size of text used in each line, which is not
compliant with TTML.

This patch makes ttmlrender lay out the lines in a block itself, rather
than using a PangoLayout to do the work. The code still uses a
PangoLayout to render the text of each element, but the overall layout
of the text in a block is now controlled by ttmlrender itself. By doing
this, ttmlrender is able to ensure that the height of each line in a
block is correct.

4d63aee36c videoaggregator: Do not mix the same buffer twice when EOS.
When entering this code path, we know that:

We received EOS on this pad.
We consumed all its buffers.

In any case, we want to replace vaggpad->buffer with NULL,
otherwise we will end up mixing the same buffer twice.

6d256d9908 directsoundsrc: Correctly calculate segsize and segtotal
segsize should be based on latency-time, and must be a multiple of the
frame size. segtotal should be based on buffer-time and segsize.

This prevents errors caused by outputting buffers that are not a
multiple of the frame size, and actually makes the buffer-time and
latency-time properties do what they're supposed to do.

18917de956 audiomixmatrix: Remove property matrix-value-array
This duplicated property is no longer needed as there is now API to
allow bindings access GST_TYPE_ARRAY (see gst_util_get/set/object_array).
Additionnally, Python has proper overrides which will make this looks
like Python. A 2x2 matrix would be set this way:

  element = matrix = Gst.ValueArray(Gst.ValueArray([1.0, -1.0]),
      Gst.ValueArray([1.0, -1.0))

Notice that you need to "cast" each arrays to Gst.ValueArray, otherwise
there is an ambiguity between Gst.ValueArray and Gst.ValueList list type.
Fortunatly, Gst.ValueArray implements the Sequence interface, so it can
be indexed like normal python matrix.

0a25fe2893 mssdemux: only add live fragments after manifest fragments
A live manifest may have a set (> LookAheadFragmentCount) of fragments
that have already been served and are stored on the server, maybe
indefinitely.  Adding the parsed live fragments after the manifest
fragments breaks duration reporting and the seekable range.

Fix by only adding parsed fragments outside the list of fragments which
assumes that the fragment list in the manifest is accurate enough to not
stray too far off what's in the retrieved data.

a3b61c8ab8 adaptivedemux: Don't send EOS on pads when there's a pending switch
When there are new pads pending for a bitrate switch, don't allow
EOS through from the old streams. It will be sent when the new pads are
ready, just before the old streams are removed.

This fixes racy bitrate switching with hlsdemux in urisourcebin
where old pads EOS before new pads appear and the entire pipeline can
EOS if those propagate fast enough
