00400a838b mssdemux: avoid streaming to fail when download is cancelled
When download was failing repeatedly, it was causing streaming to fail even though it was cancelled on purpose (stopping tasks).

bf0ea5d561 mssdemux: add a maximum error count for downloads
mssdemux will tolerate a few download errors before emitting an
error message to the bus

52c97834df mssdemux: use downloadbitrate utility for measuring bitrate
downloadbitrate keeps a short history of bitrates and helps
tracking the current average download bitrate for mssdemux

2219a3a1cc mssdemux: add bitrate-limit property
It allows the plugin to use its own downloading bitrate measures
as a feedback to select the best streams bitrate for the current
network scenario

aa1713068a mssdemux: implement live streams handling
Live streams force the demuxer to keep reloading the Manifest from
time to time, as the new fragments are being added as they are recorded.
The demuxer should also try to keep up and detect when it had to skip
fragments, marking the discont flag when that happens.

Curiously, the spec doesn't seem to mention when/how a live stream is supposed
to end, so keep trying downloads until the demuxer errors out.

c2ae981e6d mssdemux: rewriting pad tasks so that buffers are pushed by ts order
Use pad tasks to download data and an extra task that gets the earlier
buffer (with the smallest timestamp) and pushes on the corresponding
pad.

This prevents that the audio stream rushes ahead on buffers as its
fragments should be smaller

da4fad2f6f mssdemux: implement bitrate switching
When connection-speed changes, signal that we might need a bitrate
switch. During the switch, a new pad group is added and the old one
is drained and removed.

New pads also need to push newsegments before starting to stream

b9aec0ad0d mssdemux: add connection-speed property
This speed limits the maximum bitrate of streams. Currently it
is only read when starting the pipeline, but it should be used
for switching bitrates during playback to adapt to network
changes.

cb7e3d1f3b mssdemux: initial implementation of seek event handling
Adds basic handling for seek in time events. Needs to cooperate
with the downstream qtdemux so that it forwards the seeks and
the corresponding newsegments

ca4e5c34cb smoothstreaming: refactor structure names and implement url fetching
Use shorter names for the MSS manifest helper structure and functions.

Also continues the implementation of the stream fetching and pushing loop.
Now it uses the base url correctly and already fetches and pushes the fragments
downstream

7ceb023682 mssdemux: initial implementation of the pad loop
The loop will fetch a new fragment and push on its srcpad. Each
stream has its own loop

5291985efe mssdemux: pad exposing initial implementation

each stream detected in the manifest

95e87fbee9 smoothstreaming: stubs for mssdemux
Just the stubs for mssdemux element.
Also add some useful code from hlsdemux that we intend to reuse
