Currently we have been using the vp8 codec because it was the best unencumbered codec at that time. With vp9 we now have a successor that leads to smaller
files at at the same video quality and has been supported by current browsers
for a while.
With the raise of hidpi and 4K displays we need a better codec that handles
those resolutions better, so switch to vp9.

Send EOS to the complete pipeline instead of only to our own source.
When there are multiple sources in the pipeline (for example when we also
record audio), the pipeline will send the EOS to all sources in order to
shut down the complete pipeline.
Replace more direct XFixes usage with a the appropriate abstraction
API from mutter, which is guaranteed to work in wayland too.
It doesn't yet replace pointer position tracking, although probably
it should.
Also, because now we're using Mutter API, we lose the standalone
test case.

This will replace the indicator painted on the stage right now.
This unfortunately does not work for the recorder triggered by the
keybinding -- we'll simply replace the in-shell code with a keybinding
powered by gnome-settings-daemon.
The magnifier adds its own copy of the system cursor to apply the
expected transformations, so we don't need to add it again in the
recorder; this avoids two different cursors showing up in recordings,
but doesn't address the case where the cursor should not be recorded
at all, but the magnifier adds it anyway.

It looks a bit unpolished to overlap our own chrome with the recording
icon, which may happen when an existing adds UI at the bottom edge.
Fix this by using the primary monitor's workarea for the position rather
than the entire monitor.

Currently we will always record the entire screen. It has been requested
to support recording a specified area analogous to the screenshot API as
well, so add a set_area() method which allows this.

It is currently not always possible to predict the actual output filename
of a recording - the file-template does not necessarily use an absolute
path and may contain %d and %t escape sequences.
This is OK for fire-and-forget uses like the existing keyboard shortcut,
but we will soon expose the functionality on DBus and consumers of that
API might very well need to access the file after the recording. So do
the same as our screenshot API and add an optional (out) parameter to
record().

Pointer tracking is broken when the pointer is over the stage input
area. This is apparently fallout from mutter going to XInput2.
This commit changes the mouse event handling code to also use XInput2.

The screen grabber was a workaround for an extremely slow path in Mesa
when reading back pixel data from the frame buffer. It was using pixel
buffer objects by directly calling into GL to hit a fast blit path in
Intel's driver. This should no longer be necessary with the latest
Mesa because the normal read pixels path now has a fast path to just
memcpy the data. Using PBOs in that case just adds an extra
indirection because the data is read into an intermediate buffer and
then copied back out again.
We want to be able to remove the dependency on linking against libGL
directly from Gnome Shell because that will not work if Cogl is
actually using GLES. Also libGL includes GLX which means gnome-shell
ends up with a hard dependency on Xlib which hinders the goal of
getting Gnome Shell to be a Wayland compositor.

Often the first thing a user wants to do after making a recording
is post it somewhere.
This commit adds the video to recently used items, so that it shows
up prominently in open file choosers.

We want to make sure the recorder isn't finalized until the
saved recording hits disk. This means the pipeline object needs
a hard reference on the recorder.

The speed and quality properties have been removed in favor of properties
closer to the upstream library.
Removing the properies from the pipeline would result into a huge
slowdown so we have to map the old values to the new ones.
According to the source code of the old vp8enc element quality maps to
(int)(63 - quality * 6.2) for min_quantizer and max_quantizer, while
speed maps to cpu-used = speed == 0 ? 0 : (speed - 1).
So set min_quantizer and min_quantizer to 13, and cpu-used to 5 based on
the above formulas.

The default filename isn't localized and isn't the same one that
the shell sets. Just remove the fallback mechanism, and abort
recording if somebody didn't set the filename
https://bugzilla.gnome.org/show_bug.cgi?id=677434
Instead of adding every rendered frame into the recording, drop frames
and only buffer and record enough frames to match the target framerate.
Increase the default frame rate from 15 to 30, since now that we're
actually enforcing framerate, it's noticeable that 15fps is not smooth.
https://bugzilla.gnome.org/show_bug.cgi?id=669066
The default pipeline was fairly aggressive about quality, and could
be too expensive for some computers. Decrease the quality setting for
the vp8 codec from 10 to 8, and increase the speed setting from 2 to 6.
(Basically, quality affects the visual fidelity of the end result, while
speed affects how much CPU the encoder uses to get a high compression
ratio at that quality level.)
Remove videorate from the pipeline, since the GStreamer VP8 encoder can
handle variable-framerate streams. This means that we won't spend CPU
encoding duplicate frames added by videorate.

For the Intel drivers, using glReadPixels() to read into client-memory
directly from the frame buffer is much slower than creating a pixel
buffer, copying into that, and then mapping that for reading. On other
drivers, the two approaches are likely to be similar in speed. Create
a ShellScreenGrabber abstraction that uses pixel buffers if available.
Use that for screenshots and screen recording.
