This adds player widget with working play/pause controls, a seek bar
which currently only displays the current playback position, and a
button to cycle between the scaling modes.
The player uses the new PlaybackManager class to handle demuxing,
decoding, and frame presentation timing.
Currently, the volume control is non-functional.
This file will be the basis for abstracting away the out-of-thread or
later out-of-process decoding from applications displaying videos. For
now, the demuxer is hardcoded to be MatroskaParser, since that is all
we support so far. The demuxer should later be selected based on the
file header.
The playback and decoding are currently all done on one thread using
timers. The design of the code is such that adding threading should
be trivial, at least based on an earlier version of the code. For now,
though, it's better that this runs in one thread, as the multithreaded
approach causes the Video Player to lock up permanently after a few
frames are decoded.
This moves the setting of code points in CICP structs to member
functions completely so that the code having to set these code points
can be much cleaner.
The class is virtual and has one subclass, SubsampledYUVFrame, which
is used by the VP9 decoder to return a single frame. The
output_to_bitmap(Bitmap&) function can be used to set pixels on an
existing bitmap of the correct size to the RGB values that
should be displayed. The to_bitmap() function will allocate a new bitmap
and fill it using output_to_bitmap.
This new class also implements bilinear scaling of the subsampled U and
V planes so that subsampled videos' colors will appear smoother.
This adds the `nologin` application to the system. This application
will look for `/etc/nologin`. If it is present, it will display the
message in the file. Otherwise, it will display an error about the
current account being unavailable.

Previously, init() in BackgroundAction.cpp was calling
Core::Object::set_name, which does not affect the displayed thread name
which is displayed by the system monitor. This changes it to pass the
name to the thread constructor.
This allows Actions that change based on some state to update their
associated buttons' text and tooltips to match their new text. The
play/pause button in SoundPlayer (and VideoPlayer if it's merged)
will now change tooltips when the playback changes state, rather than
always displaying "Play (Space)".
With so much infrastructure implemented, we can finally add the last
piece of this puzzle - the fetch() method itself!
This contains a few hundred lines of generated code as handling the
RequestInfo and RequestInfo parameter types manually is not feasible,
but we can't use the IDL definition as the Window object is handwritten
code at the moment.
It's neatly tucked away in Bindings/ and will be removed eventually.
This implements the following operations from section 4 of the Fetch
spec (https://fetch.spec.whatwg.org/#fetching):
- Fetch
- Main fetch
- Fetch response handover
- Scheme fetch
- HTTP fetch
- HTTP-redirect fetch
- HTTP-network-or-cache fetch (without caching)
It does *not* implement:
- HTTP-network fetch
- CORS-preflight fetch
Instead, we let ResourceLoader handle the actual networking for now,
which isn't ideal, but certainly enough to get enough functionality up
and running for most websites to not complain.
There will be a lot of different cases where we'll return an error
response, and having a customized Promise rejection message seems quite
useful.
Note that this has to be distinct from the existing 'status message',
which is required to be empty in those cases.
The header-specific ABNF rules are completely ignored for now, but we
can at least extract a single header value, which at least works for
simple cases like `Location`-based redirects.
