a16cd5d2a5 vorbisenc: push an updated segment stop time when we know it
When encoding, libvorbis will tell us how many samples are encoded
in the buffer it returns. This number may be less than the maximum
of samples in the block, if this is the last packet. In we have no
segment end time, we set it to the end time of that last sample to
tell downstream that the buffer contains less samples.

aa5b5b9085 oggmux: set correct granpos on last page when samples are clipped
Samples may be clipped at the end, and this is conveyed by a
granulepos that's smaller than it would otherwise be. Use the
segment stop time to detect this, and calculate the right
granulepos.

a93cc13d42 oggdemux: fix last buffer timestamp when samples are clipped
The end of a stream can be clipped by setting the granulepos of
the last page to a lower value that it otherwise would be.

900d0267d5 basetextoverlay: segfault when xpos >= video size
When the xpos is given as greater than or equal to the video size,
we get a segfault, due to improper condition.
Hence adding proper conditions.

1cc311156c basetextoverlay: Fix segfault when overlay outside the frame
When the textoverlay is set outside the video frame by deltax or deltay the
calculation segfaults, but it is also  unnecessary since it doesn't need to be
displayed. So we should clip the text.

b7ab2f0b08 vorbisdec: don't reorder streams with channels count greater than eight
vorbis_reorder_map is defined for eight channels max. If we have more
than eight channels, it's the application which shall define the order.
Since we set audio position to none, we just interleave all the channels
without any particular reordering.

3ecb8bea22 basetextoverlay: Do not fail the negotiation if query fails
The allocation query failure doesn't mean that the negotiation
has failed as the element can allocate buffers itself.

Instead, only fail if the pads are flushing and the allocation
query failed.

76ce112994 basetextoverlay: schedule reconfigure on source pad when negotiation fails
The source pad might be flushing while negotiating, resulting in
set_caps or the ALLOCATION query failing. In this case set the
reconfigure flag on the source pad so that negotiation is retried on the
next buffer.

501a295fa1 basetextoverlay: remove unneeded cairo transparence setting
he code here:

http://cgit.freedesktop.org/gstreamer/gst-plugins-base/tree/ext/pango/gstbasetextoverlay.c#n1554

should make transparent the box that contains the text, I think this code is
not correct, it should be:

if (overlay->want_shading) {
    double alpha = overlay->shading_value / 255.0;
    cairo_paint_with_alpha (cr, alpha);
  }

however I think this code could be removed, we already do a shaded background,
why shade the box behind the text with cairo too? only one shading is needed so
we must shade with cairo or with methods like these:

http://cgit.freedesktop.org/gstreamer/gst-plugins-base/tree/ext/pango/gstbasetextoverlay.c#n1642

not both

a65b307349 basetextoverlay: properly fallback to non-overlay caps
When downstream claims to accept the overlay meta but fails to
provide it in the allocation query, properly fallback to setting
a new caps without the overlay meta as that is not going to be used.

Only do this if the original caps doesn't have the overlay already,
otherwise there isn't much that can be done.

be1b5b3de7 oggdemux: don't set segment.base in pad_submit_packet()
Setting segment.base in the segment sent from gst_ogg_demux_handle_page() is
enough to ensure that chained oggs are played corretly (see bgo#706569).

Tweaking the base in gst_ogg_pad_submit_packet() as well result in delays when
playing a file with start != -1.

3c8d3465bf oggdemux: accumulate base time

a080c0ebbf basetextoverlay: rework caps negotiation
Make textoverlay negotiate caps more correctly.

1) Check what caps we received in the video-sink
2) If it already has the overlay meta -> use it directly
3) If it doesn't, textoverlay try adding the overlay meta and using it,
   if downstream doesn't support it, just use what is received in the
   video-sink
4) Check if the allocation query also supports the meta to enable
   really using it

Before it wasn't really doing renegotiation of any kind, just
re-checking if it should use the overlay meta or not

Also had to update the caps in the test as memory:SystemMemory seems
to be required when you use a caps feature otherwise intersection/subset
checks will fail.

3b2d583373 alsasink: fix occasional crash intersecting invalid values
When a pipeline using alsasink and push mode upstream fails
to preroll, the following state will be the case:
- A loop upstream will be PAUSED, pushing a first buffer
- alsasink will be READY, pending PAUSED, because async

On error, the pipeline will switch to NULL. alsasink is in
READY, so goes to NULL immediately. It zeroes its cached
caps. Meanwhile, the upstream loop can cause a caps query,
conccurent with the state change. This will use those cached
caps. If the zeroing happens between the NULL test and the
dereferencing, GStreamer will critical down in the GstValue
code.

Since it appears that such a gap between states (PAUSED
and pushing upstream, and NULL downstream) is expected, we
need to protect the read/write access to the cached caps.

This fixes the critical.
