When reading an SWF, search for FileAttributes and
SetBackgroundColor and return this along with the header data
because it's useful (in particular, the AS3 flag).
* Remove all unwraps from web/lib.rs.
* Add convenience methods for grabbing the Ruffle web instance.
These methods also avoid panics/unwraps when borrowing
`RefCell`/`Mutex`.
* Use `warn_on_error` to avoid unwraps from web APIs.
Add `RufflePlayer.metadata` that exposes the SWF header fields to
JavaScript.
Add `RufflePlayer.readyState` and fire a `loadedmetadata` event
once the metadata is available, mimicking the HTML5 media APIs.
* #[derive(Collect)] should be before #[collect]
* Replace redunant `&buf[..]` with `buf`
* Changes most cases of UPPERCase to UpperCase
* Allow upper_case_acronym on most SWF types, as they are from
SWF spec/more annoying to change.
Since 19034b7, clip event scripts are returned as slices from the
SWF. This caused a panic when a movie was loaded into a clip,
because the loaded clip's `movie` would be used as the source for
clip events. However, clip events are placed by the parent's
PlaceObject tags, so the movie in this case should be the parent's
movie.
Fixes#2870.
This unifies the code path for event sounds and stream sounds.
Both `AudioBackend::start_stream` and `start_sound` return a
`SoundHandle`. `stop_stream` is removed (`stop_sound` can be
used for both cases).
Also removes references to `CharacterId` from the `AudioBackend`
(instead, an increasing ID is returned to identiy streams while
loading).
Add an AudioManager struct to handle this list of actively playing
sounds. This will maintain information for each sound instance,
such as the owning display object, AVM1 object, etc.
This will allow us to implement the awkward AVM1 Sound API in a
fairly backend-agnostic way.
