2918dff2e0 adaptivedemux: improved error message if availabilityStartTime is missing for a live stream
For a live mpd, if availabilityStartTime is missing, adaptive demux asserts
with: Unexpected critical/warning: gst_date_time_to_g_date_time: assertion
'datetime != NULL' failed.

This patch improves the error message to:
Unexpected critical/warning: gst_mpd_client_seek_to_time: assertion
'client->mpd_node->availabilityStartTime != NULL' failed

b7a0be23c6 adaptivedemux: replace ghostpad with a standard pad
Handling the ghostpad and its internal pad was causing more issues
than helping because of their coupled activation/deactivation
actions.

As we have to install custom chain,event and query functions it is
better to use a floating sink pad internally in the demuxer and just
use those pad functions to push through a standard pad in the demuxer

066f0dcda0 gltransformation: implement navigation events
Reverses the transformation applied through the properties and forwards the
event.

The process for finding the coordinates on the video are as follows:
1. Convert the given pointer_x and pointer_y to model space at the near and far planes
2. Get the equation of the video plane
3. Find where the ray in 1 intersects the plane
4. Profit!

95a14fd470 sbc: sbcdec: Fix frame length calculation
SBC frame length calculation wasn't being rounded up to the nearest byte
(as specified in the A2DP 1.0 specification, section 12.9). This could
cause 'stereo' and 'joint stereo' mode SBC streams to have incorrectly
calculated frame lengths.

8c7ea6fb87 opencv: remove check for OpenCV version
After commit 64080e632, configure checks for all the header files that
should be available in OpenCV 2.3 and later. If any of these files isn't
there the OpenCV elements won't be part of the build.

No need to recheck for opencv2/legacy/legacy.hpp again in
gstpyramidsegment.h. Minimum supported OpenCV version must have this header
and configure already checks for it. Removing check.

bf57be7fc7 hlsdemux: fix reverse playback seek with snap flags
Properly handle snap flags during reverse seeking. In this case
the before/after are also reversed, so handle those as such.

For example: with a sequence of 1s fragments:

|-- 0 --|-- 1 --|-- 2 --|-- 3 --|

If you seek to 1.5s it is inside fragment 1. With reverse and

snap-before: should play from the end of fragment 1
snap-after: should play from the end of fragment 0

00587eb561 rtmpsrc: check for failed RTMP context alloc
Avoids an unlikely crash.

Arguably, if allocation fails we have no chance of
recovering but nonetheless, RTMP_Alloc can fail and
librtmp's RTMP_init() (called next) assumes a non-NULL
pointer is passed without checking.

Additionally, unify exit path on error.

77b7864670 motioncells: fix splitting of RGB color string
No need to attempt splitting the RGB string in 255 tokens
if we only expect 3.

Left max_tokens at 4 to preserve the current logic (which
allows for extra stuff at the end) and added a warning on
parsing failure instead of silently discarding the value.

f6bff8f5f5 hlsdemux: unquote all the quoted-string attributes
The URI attribute from the EXT-X-KEY tag and the URI attribute from the
EXT-X-I-FRAMES-ONLY tag are both quoted-string attibutes that have their
quotation marks removed during parsing. The CODECS attribute of the
EXT-X-STREAM-INF is also a quoted-string attribute, but this attribute
was not being un-quoted.

This commit changes the parser to always unquote all quoted-string
attributes and adjusts the unit tests to this new bevahiour for the
CODECS attribute.

An additional test is added to check that parsing of all of the fields
in the EXT-X-STREAM tag is correct, including those that contain comma
characters.

8be5551dff hlsdemux: fix potential error leak
Clear error as soon as we determine that the download failed,
otherwise there are code paths where we might return without
clearing it ever, which would leak the GError then. Also, we
can pass a NULL GError pointer to _fetch_uri(), so just do that
instead of passing one that we're going to just free again
right away anyway.
