560910 - <audio><embed></audio> Don't pop up "Install Missing Plugins" for idle fallback content

Status: RESOLVED INCOMPLETE

(Core Graveyard :: Plug-ins, defect)

Description

[j.j.]

Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.3a5pre) Gecko/20100420 Minefield/3.7a5pre

Without a plugin for WAVE audio files installed, I get a needless and confusing "Install Missing Plugins" popup in cases like this:

<audio src=foo.ogg> <embed src=foo.wav> </audio>

STR
1. Make sure you have no plugin enabled for .wav files
2. Visit http://www.elektronotdienst-nuernberg.de/bugs/tel-audio.html
3. "Install Missing Plugins" message pops up
4. Ringing sound works fine

expected:
No "Install Missing Plugins" message, since this page works without plugin.

How do we know it works?  If you had a plugin for that <embed>, we should be playing it (unless HTML5 has since redefined how this works) and we have no way to know the wav and the ogg are the same thing...

No, per HTML5 4.8.7 content inside <audio> is 
  "... intended for older Web browsers which do not support audio, so that
   legacy audio plugins can be tried ...".

I expect ignoring <embed> inside <audio> completely, with or without plugin installed.

But nothing in the spec actually says to do that last I checked...

Do you think both, <audio> and <embed> should play? It isn't played twice if I install QuickTime, and that's fine.

Regardless of that and what the spec says or not says explicitly, the user gets this wrong (or completely misleading) message:

"Additional plugins are required to display all the media on this page."

Therefore this is a bug (all media on this page work well).


Furthermore: Claiming "missing plugins" for fallback content is against the intention of the audio element (assuming that one intention of <audio> is creating plugin-less web content).

No, but I think the spec needs changes to make that actually be the case...

> It isn't played twice if I install QuickTime

Yes, which is why this bug is still open.

Resolving old bugs which are likely not relevant any more, since NPAPI plugins are deprecated.
