fragment.

to download and deliver them downstream for playback.

d68fffc217 dashdemux: handle top-level index urls 
Parse and provide access to top-level index segments if available.
dashdemux should push those whenever a header is pushed.

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.

the surround functions should already check that. Removing them.

665d59edba dashdemux: only start timestamp from 0 for live stream 
We only want to adjust the timestamps so that they start from 0 for live
streams. Non-live streams already start from 0 and after a seek we actually want
to timestamp to be the position we seek to.

4f9f0b84cf dashdemux: make timestamps start from 0 
Non-live streams should timestamp buffers with a running-time starting from
0. Since we already push a 0 -> -1 segment, bring the timestamps to 0
by subtracting the initial timestamp.

d9baed8302 dash: mpdparser: do not cleanup xml lib too early 
The xmlCleanupParser function seems to cleanup all statically
allocated libxml variables, making it unusable. We can't guarantee
that dashdemux won't need it anymore, so better not call it.

14feeb3ccb dashdemux: reimplementing live streams manifest updates 
Manifest updates should be done periodically for live streams,
this patch makes the demuxer create a new manifest client for
the new version and transfers the stream position to the new
one, discarding the old one afterwards.

94dcb60127 dashdemux: change bitrates based on the stream bitrate 
Do not use a global bitrate as the sizes of the fragments matter
when calculating the download rate as the connection setup time is
also being taken into the download duration, a smaller fragment
will have a lower bitrate than a larger one.

This avoids switching the bitrates for streams frequently because
of bitrate mismatches
