This structure is always allocated by GStreamer, can't be
subclassed or extended, and is never allocated or used on
the stack, so we don't need any padding and can extend it
as we please.
When requesting a pad from a template and it's already linked, this
means it was a static pad. Since we only want to return an *available*
pad, we must return NULL ... but we must also remove the reference
we got from getting that static pad.
The "No need to unref" message (which wasn't true for quite some time)
dates back from the very very very first commit introducing the 0.10
features.
The caller might pass arbitrary data here that caused the error, and
trying to set invalid UTF-8 in a GstStructure causes it to be not set at
all. Later when trying to parse it, the field will not exist and the
return value will point to invalid memory. Prevent this by storing NULL
instead.
Also print a g_warning(), the caller should never ever do this to begin
with.
The git:// protocol is problematic from a security perspective, as
it provides no authenticity of data. https:// also works better in
environments with restricted network connectivity.
Also add CLONE_OPTS to do shallow checkouts more easily.

This was totally non-obvious, the kind of big problem is that subclasses must
be able to unblock their streaming thread and continue exactly where they left off
on unpause!

The correct behaviour of anything stuck in the ->render() function
between ->unlock() and ->unlock_stop() is to call
gst_base_sink_wait_preroll() and only return an error if this returns an
error, otherwise, it must continue where it left off!

Don't use templates for the man pages, the API version change is a rare
event, so it's not really worth keeping in place the "sed" boilerplate
to have it set at build time.
Shipping the final man pages directly also makes it easer to install the
man pages with meson (in a future commit).
Note that now all the occurrences of the programs names have the API
version as a suffix.
Traditionally the example command lines looked like:
gst-launch ...
Now they look like:
gst-launch-1.0 ...
This reflects the actual programs names and makes it easier to copy and
paste the example commands.
Also, the .gitignore file is adjusted not to ignore the final man pages
anymore.
You may need to clean your src/build directory before pulling in this
patch.

Allows proxying the control interface from one property on one GstObject
to another property (of the same type) in another GstObject.
E.g. in a parent-child relationship, one may need to
gst_object_sync_values() on the child and have a binding (set elsewhere)
on the parent update the value.
Note: that this doesn't solve GObject property forwarding and must be
taken care of by the implementation manually or using GBinding.

Add unit test to ensure that.
It can be a normal execution path to do some map trials and there is
no need to worry the user in that case.
The application has to check the return value of gst_memory_map.

It might've failed just because of flushing or other things, and we
should retry again on the next possibility if something ever calls in
here again.

When running in sync-by-running-time mode, pad groups
that have exactly 1 pad and it's not-linked might never
wake up after computing a high time, as the per-pad-group
high time was only recomputed when a pad in the group
advances.
Wake those up using the global multiqueue high-time across
all other groups instead.

To make sure the value is only expanded/used once, in case
there are side effects to it, and to avoid calculating it
or looking it up multiple times if there is a calculation
or lookup involved.
Check the correct segment format value.
parse->segment.format is the format we're outputting in,
not the upstream format. Use parse->priv->upstream_format instead,
and make sure it's set in pull mode.
If the parser is not parsing a raw elementary stream, restrict
the position, duration and conversion query replies to
things we can sensibly answer about - especially don't do
random conversions to/from bytes.
When subtracting queued data sizes from upstream queries
in queue, queue2, downloadbuffer and typefind, clamp the
result to not go negative, in case upstream returned
a nonsense value that's too small (as could happen if
upstream is estimating, or just broken)
Use grep -o to grab the log message only. This makes it work with colored log
files too. Prefilter the log to not catch tracer classes.
Update the commandline for the script in the docs.
