Godot has a ScriptProcessorNode audio driver implementation for the
(deprecated) Web API.
As reported by some users, this fallback was not properly re-added
during the Godot 4 transition, and was left as "dead code".
While the API is deprecated, it is still supported by most browsers, and
some WebView may not implement AudioWorklet correctly (the new
recommended API).
This commit re-adds the ScriptProcessorNode implementation as a fallback
if the AudioWorklet driver fails to initialized (and can be forced if
desired via project settings as usual).
The spec says that Response.body can be null (in the event of requests that should have no body, like HEAD requests) and Firefox adheres to it which results in request failure for HEAD requests on Firefox for web exports.
This commit addresses that by treating a null body as an "empty" body (without using a polyfill) and avoids changing the request lifecycle as much as possible.
PR review changes:
- Use == instead of strict ===
- Do not use ?? null
- Comment formatting
It wrongly returned 20 on array buffers, which used to be the enumerator
value of Godot 3.x's type PoolByteArray, and now is the value of type Color,
while it should return 29 which is the enumerator value for PackedByteArray.
Body length cannot be reliably retrieved from the web.
Reading the "content-length" value will return a meaningless value when
the response is compressed, as reading will return uncompressed chunks
in any case, resulting in a mismatch between the detected body size and
the actual size returned by repeatedly calling read_response_body_chunk.
Additionally, while "content-length" is considered a safe CORS header,
"content-encoding" is not, so using the "content-encoding" to decide if
"content-length" is meaningful is not an option either.
We simply must accept the fact that browsers are awful when it comes to
networking APIs.
- Rename all instances of `capture_start()` and `capture_end()` to their new
names. Fixes#72892.
- More internal renames to match what was started in #69120.
- Use `override` consistently so that such refactoring bugs can be caught.
- Harmonize the order of definition of the overridden virtual methods in each
audio driver.
- Harmonize prototype for `set_output_device` and `set_input_device`.
