263040 - Sound does not play on Mac using nsSound

Status: RESOLVED DUPLICATE of bug 194632

(Core Graveyard :: GFX: Mac, defect)

Description

[Tony Goold]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.7) Gecko/20040803 Firefox/0.9.3

Trying to play sounds in Javascript, using the nsISound interface, I found I was
unable to play a sound from a file. In nsSound.cpp, in the body of
nsMovieSoundRequest::PlaySound(), the call to ::NewMovie results in a -2020
(movieToolboxUninitialized) error. This is because ::EnterMovies needs to be
called before QuickTime movie functions are available. The following change to
nsMoviePortOwner::EnsureMoviePort fixed the problem for me:

  if (!sMoviePort)
  {
    Rect        gWorldBounds = {0, 0, 12, 12};
    (void)::NewGWorld(&sMoviePort, 8, &gWorldBounds, nil, nil, 0);
+   ::EnterMovies();
  }


Reproducible: Always
Steps to Reproduce:
1. Get an nsIFileURL (e.g., url) with nsIFilePicker
2. Create an nsSound object (e.g., sound)
3. sound->Play(url);

Actual Results:  
No sound is played.

Expected Results:  
A sound should be played.

there's also an ExitMovies, it looks like you're only really supposed to call
EnterMovies once. the docs also clearly indicate that you're supposed to check
the return value from EnterMovies.

At some point EnterMovies was called during browser init (in appshell or
something). That code seems to have been lost.

This bug has had no comments for a long time. Statistically, we have found that
bug reports that have not been confirmed by a second user after three months are
highly unlikely to be the source of a fix to the code.

While your input is very important to us, our resources are limited and so we
are asking for your help in focussing our efforts. If you can still reproduce
this problem in the latest version of the product (see below for how to obtain a
copy) or, for feature requests, if it's not present in the latest version and
you still believe we should implement it, please visit the URL of this bug
(given at the top of this mail) and add a comment to that effect, giving more
reproduction information if you have it.

If it is not a problem any longer, you need take no action. If this bug is not
changed in any way in the next two weeks, it will be automatically resolved.
