The current location of the IPC invocation is often too soon. We reach
it before the audio file has completely finished downloading / loading,
thus there isn't an AudioTrack object yet.
Instead, wait until we are actually playing the audio to invoke the IPC.
This is particularly frequent on bandcamp.
Most browsers have some indicator when audio is playing in a tab, which
makes it easier to find that tab and mute unwanted audio. This adds an
IPC to allow the Ladybird chromes to do something similar.
This URL library ends up being a relatively fundamental base library of
the system, as LibCore depends on LibURL.
This change has two main benefits:
* Moving AK back more towards being an agnostic library that can
be used between the kernel and userspace. URL has never really fit
that description - and is not used in the kernel.
* URL _should_ depend on LibUnicode, as it needs punnycode support.
However, it's not really possible to do this inside of AK as it can't
depend on any external library. This change brings us a little closer
to being able to do that, but unfortunately we aren't there quite
yet, as the code generators depend on LibCore.
This commit introduces a WEB_SET_PROTOTYPE_FOR_INTERFACE macro that
caches the interface name in a local static FlyString. This means that
we only pay for FlyString-from-literal lookup once per browser lifetime
instead of every time the interface is instantiated.
This commit un-deprecates DeprecatedString, and repurposes it as a byte
string.
As the null state has already been removed, there are no other
particularly hairy blockers in repurposing this type as a byte string
(what it _really_ is).

With this change, we now have ~1200 CellAllocators across both LibJS and
LibWeb in a normal WebContent instance.
This gives us a minimum heap size of 4.7 MiB in the scenario where we
only have one cell allocated per type. Of course, in practice there will
be many more of each type, so the effective overhead is quite a bit
smaller than that in practice.
I left a few types unconverted to this mechanism because I got tired of
doing this. :^)
This commit removes DeprecatedString's "null" state, and replaces all
its users with one of the following:
- A normal, empty DeprecatedString
- Optional<DeprecatedString>
Note that null states of DeprecatedFlyString/StringView/etc are *not*
affected by this commit. However, DeprecatedString::empty() is now
considered equal to a null StringView.
This should allow us to add a Element::attribute which returns an
Optional<String>. Eventually all callers should be ported to switch from
the DeprecatedString version, but in the meantime, this should allow us
to port some more IDL interfaces away from DeprecatedString.
Instead of having a nested enum within a struct, use the macro
AK_ENUM_BITWISE_OPERATORS to add all the convienent has_flag free
functions and such for ease of use.
Stop worrying about tiny OOMs. Work towards #20449.
While going through these, I also changed the function signature in many
places where returning ThrowCompletionOr<T> is no longer necessary.
This allows increasing and decreasing the media volume by 10% with the
up and down arrow keys, respectively. This also allows toggling the mute
state with the M key.
This allows seeking backwards and forwards by 5 seconds with the left
and right arrow keys, respectively. This also allows seeking to the
beginning and end of the media track with the home and end keys.
Mostly seen on macOS, but when we toggle playing a media element, we
need to update its layout node's display to ensure the change is
reflected on the playback button. Further, when setting the element's
display time, we need to update the display to ensure the change is
refelected on the media timeline.
Previously, an audio loader could succeed for an HTMLVideoElement that
contains a video file, which caused the duration to be set to the bogus
duration of the audio loader instead of the correct duration from the
video container. Instead of setting the duration based on audio always,
set it to the video duration if we are creating a video element.
This implements the ability to drag the timeline and volume buttons on
UA-rendered media controls. The two behave a bit differently:
Volume is updated as the user drags the volume button. This isn't a very
expensive operation, so updating in real-time and hearing the volume
change feels nice.
The current time, on the other hand, is not committed until the user
releases the mouse button. Performing a seek every time we get a mouse-
move event is pretty laggy, especially for video. However, we still want
to render updates on the timeline itself (so the position of the button
and the timestamp update as you drag). To do so, we internally pause the
media and override the timestamp provided to the layout node.
In the future, we may be able to seek video periodically to provide some
visual feedback. For example, we can seek after every N seconds of
scrubbing, or when the user pauses scrubbing for a while.
Now that we support audio, we can start correctly reporting we support
certain audio mime types!
Required by certain sites like Gartic Phone, which fails to load audio
because we didn't return a non-empty string for `audio/mpeg`:
```
"https://garticphone.com/sounds/turnundefined", Error: Load failed: 404
```
```js
(new Audio).canPlayType("audio/mpeg") && (this._extension = ".mp3"),
```
It can take some time to download / decode a media resource. During this
time, its duration is set to NaN. The media control box would then have
some odd rendering glitches as it tried to treat NaN as an actual time.
Once we do have a duration, we also must ensure the media control box is
updated.
Now that the processResponseConsumeBody algorithm receives the internal
response body of the fetched object, we do not need to go out of our way
to read its body from outside of fetch.
However, several elements do still need to manually inspect the internal
response for other data, such as response headers and status. Note that
HTMLScriptElement already does the new workaround as a proper spec step.
