An MP3 "stream" sound can sometimes have frames without a
SoundStreamBlock tag, despite the SWF spec saying there should
at least be a tag with 0 samples on each frame. Ruffle would
stop the sound in this case, but the Flash Player may or may not
stop thje sound in the audio depending on the number of "empty"
frames. This could cause the audio to stutter as it continuously
stopped and restarted.
Handle this by keeping track of how many samples we've encountered
in MP3 blocks, and deducting the amount of samples consumed by each
timeline frame. Stop the sound if we run out of samples, as opposed
to when we hit a frame without a SoundStreamBlock.
Fixes#3817.
The first argument of all events is the target MovieClip. It was
incorrect.
Also, `onLoadComplete` accepts an additional `httpStatus` argument.
Stub it to 0.
Remove unnecessary calls to `introduce_loader_handle`, which are
dominated by `add_loader` that already calls it. As a result, `add_loader`
remained the only function to call `introduce_loader_handle`, so inline
it there.
Since they are identical (they both load the URL as a string, then
fire the `onHTTPStatus` and `onData` events). In fact, AVM1's
`XML.prototype.load` and `LoadVars.prototype.load` functions are
both defined as `ASnative(301, 0)`, so they invoke the same native
code under the hood.
The path starting position was not being set correctly after a
moveTo command, which could cause stray strokes to appear in the
drawing.
Fixes#5598, #5768, #5957.
`XmlNode::is_as2_compatible` returns `false` for `XmlNodeData::DocType`
nodes, which means they are not included in string representations of
XML documents, and they cannot be traversed using the DOM methods.
So don't create those when parsing an XML from string, but still
store the `DOCTYPE` declaration string on the `XmlDocument`, which
is accissible through the `.docTypeDecl` property.
`XmlNode::is_as2_compatible` returns `false` for `XmlNodeData::Comment`
nodes, which means they are not included in string representations of
XML documents, and they cannot be traversed using the DOM methods.
So simply don't create those when parsing an XML from string.
Now that `replace_with_str` is defined in `XmlDocument`, there is
no need anymore for a separate function that handles nodes which have
document-wide implications.
Previously Ruffle's AVM1 runtime incorrectly permitted calling `XML`
functions on `XMLNode` objects. For example:
```as
var xml = new XML("<a><b></b></a>");
trace(XML.prototype.createElement.call(xml.firstChild, "aaa")); // traces "undefined" in Flash, but "<aaa />" in Ruffle before this commit.
```
Disallow this by using the newly-reintroduced `XmlObject` for `XML` objects
(rather than `XmlNodeObject` that represents also `XMLNode` object), and check
for it in all `XML` builtins.
