a8a355108a dashdemux: use more appropriate data structures for parsing
Replaces the 2 likely larger lists with more appropriate structures
to improve performance.

Replaces S nodes GList for a GQueue, this reduces latency to startup
because of traversing the list just append an element.

Replaces the processed media segments GList for a GPtrArray as it is
constantly acessed by index during playback.

9a38127467 dashdemux: prevent assertion when duration is unknown
Duration from segment being unknown is a issue from the MPD and not
a programming issue, so the assert isn't useful here. Instead check
and return an error code so the caller can fallback to alternatives

5ad2a2d161 dashdemux: Change first fragment selection for live streams
When dashdemux selects its first fragment, it always selects the
first fragment listed in the manifest. For on-demand content,
this is the correct behaviour. However for live content, this
behaviour is undesirable because the first fragment listed in the
manifest might be some considerable time behind "now".

The commit uses the host's idea of UTC and tries to find the
oldest fragment that contains samples for this time of day.

5920ee2777 dashdemux: Implement inheritance for certain MPD elements
According to the MPEG-DASH spec, certain elements (i.e.
SegmentBase, SegmentTemplate, and SegmentList) should inherit
attributes from the same elements in the containing AdaptationSet
or Period.

Updated the SegmentBase, SegmentTemplate, and SegmentList parsers
to properly inherit attributes from the corresponding elements in
AdaptationSet and/or Period.

5e0ed52880 dashdemux: Properly detect presence of xml attributes
Convert all xml attribute/content parsing functions to return a
boolean value indicating whether or not the attribute/content was
present.  We need this finer-grained control in order to properly
implement the inheritance policies described in the spec

Also fixed several memory leak conditions when handling errors in
the xml attribute/content parsing functions.

45111f2efe dashdemux: Cleanup memory allocation/deallocation
Ensure that g_free/xmlFree is used correctly based on how the
memory was allocated.

When deallocating GLists, there were many places that were using
g_list_foreach and g_list_free.  Converted these occurrences to
call g_list_free_full.

Add NULL checks to all xmlFree calls since the documentation does
not guarantee that passing NULL is safe

In places where we are strdup'ing memory allocated by libxml2,
changed those calls to use xmlMemStrdup().

There were several places where we were missing g_slice_free when
deallocating a top-level node structure.

407f3e1856 opencv: Add colour image enhancement element based on Retinex algorithm
Add colour image enhancement element based on Retinex algorithm. Two types
exist, namely basic and multiscale; both are described in this article:

Rahman, Zia-ur, Daniel J. Jobson, and Glenn A. Woodell. "Multi-scale retinex
for color image enhancement." Image Processing, 1996. Proceedings.,
International Conference on. Vol. 3. IEEE, 1996

Visually speaking the result looks a bit funny, but is pretty invariable to
lightning changes, which is good for some applications, like image
segmentation.

ef66e39d03 eagl: fix handling of surface dimension changes
Detect when the eagl surface changed its dimension (when the user rotates
the device for example) and adapt the egl internals to draw to that,
preventing that ios resizes the image again when drawing.

This is particularly harmful when eagl would scale down a image
to draw and the ios screen would scale it back up because the
surface is now bigger than when the element was configured.
