5d4388bf9e mssdemux: always use timescale for gst timestamp calculation 
Not doing this can lead the demuxer to attempt downloading fragments
for an invalid start time. The server would then send a HTTP
Precondition failed error, the demuxer would try some more times to
download the invalid fragment and eventually error out.

2526c7b286 mssdemux: use correct function to clear fragment info 
Just freeing the url won't reset the byte ranges and can lead to wrong
ranges being used.

f7a1649c77 adaptivedemux: add bitrate-limit property 
Move the property from subclasses to adaptivedemux, it allows
selecing the percentage of the measured bitrate to be used when

e9ab79dc36 adaptivedemux: add connection-speed property 
Allows to set a bitrate directly instead of measuring it internally
based on the received chunks. The connection-speed was removed from
mssdemux and hlsdemux as it is now in the base class

de246c6741 mssdemux: fix crash while setting bitrate in caps structure 
q->bitrate is a guint64, but G_TYPE_INT may read fewer bits
off the stack, and if we pass more then the NULL sentinel
may not be found at the right place, which in turn might
lead to crashes.

8b63a16af0 mssdemux: fix reverse playback fragment tracking 
Rework reverse fragment traversing with repetition fields to prevent
NULL pointer deref and avoid never advancing a fragment as the variable
is unsigned and would always be non-negative.

a2c31e38d1 mssdemux: support manifests with repetition fragments 
Read the "r" attribute from fragments to support fragments nodes
that use repetition to have a shorter Manifest xml.

Instead of doing:
<c d="100" />
<c d="100" />

You can use:
<c d="100" r="2" />

e289ab07c1 mssdemux: synchronize with the download loop thread to signal it to continue 
If EOS or ERROR happens before the download loop thread has reached its
g_cond_wait() call, then the g_cond_signal doesn't have any effect and
the download loop thread stucks later.

01ccac24fa mssdemux: fix clearing of eos state in pads 
The internal pad still keeps its EOS flag and event as it can be assigned
after the flush-start/stop pair is sent. The EOS is assigned from the streaming
thread so this is racy.

To be sure to clear it, it has to be done after setting the source to READY to
be sure that its streaming thread isn't running.
