We can't call gst_element_send_event() from a streaming thread as it gets the
state lock. Instead call the send_event method directly until we have a nice API
for this in basesrc.

Fixes #588746

Fixes #587695

See #587695

Fixes #588747

We do this by letting the basesrc base class handle the tags.

Keep track of the max requested position and compare this to the write position
in the temp file to get the current amount of buffered data.
Fix memleak of all incomming buffers.

Fixes #588551

We shouldn't really depend on elements from -bad for stream
selection in playbin2, so use a private copy of input-selector
until the selector plugin is ready to be moved to -base or -good.
Fixes #586356.

Not hooked up yet though. See #586356.

Fixes bug #588550.

Give up and discard and recreate the alsasrc after checking it can
be opened, due to some strange crash inside alsa when we don't.

Wait for the alsasrc to return to NULL after setting it to PAUSED for
testing, otherwise it leads to segfaults later on.

Make the liveadder test succeed silently when it can't be completed
either because alsasrc is unavailable, or because the device is
inaccessible.

Differentiate subtitle streams and lyrics/cracktastic/complex streams via
the category string in the headers. This seems like a useful distinction
to make, and also seems more future-proof. See #525743.

See #525743.

Treat uri-schemas incasesensitive. This is mandated in rfc2396 section 3.1.
Fixes not showing buffering messages e.g. for HTTP://...

Make short-desc short - its used in the toc. Strip uneeded markup.

Remove methods from video base classes that have moved to -bad.
Add gst_netaddress_to_string

Add a general documentation blurb for the GstNavigation functionality.
Still lacks some example code and detail on how to implement it.

Add siren7 caps to the RIFF parser.

Enumerate v4l devices using gudev if available.

Fixes bug #583640.

Keep the pipeline paused when we detect download buffering. The user has to
manually start the pipeline for now because we can't estimate when the buffering
will finish or when we have underrun.

Don't flush the file by closing and opening it but instead use g_freopen. This
avoids a deadlock in shutdown because we emit the temp-location property change
with the wrong lock held.

Fix the construction of the temporary filename construction as the application
name can be NULL and we don't want a separator between the prgname and the
template.

Add a new playbin2 flag (initially disabled) to enable progressive download
buffering in uridecodebin.

Add a download property that will attempt to configure queue2 into progressive
download buffering.
Make sure we only enable download buffering for quicktime and flv formats.

Add a new temp-template property so that queue2 can securely allocate a
temporary filename. Deprecate the temp-location property for setting the
location but still use it to notify the allocated temp file.

Adder can only handle one common format accross the pads. Thus one needed to add
a capsfilter afterwards and manage the caps. Now one can simply set the caps on
the property.

The seek-test needs a real audiosrc. Also add a test that checks that adder is
reusable. Finaly handle warnings as warnings to fix a assertion.
