Currently, plugins are not working under BeOS version of mozilla 'Bezilla'.
I implemented some to get plugins work.

I modified nsPluginsDirBeOS.cpp to handle supported mime-types by BeOS's way.
Also, I added BeOS implementation in ns4xPlugin.cpp, copied from XP_UNIX #ifdefs.

## result
I can get some plugins work.
Flash Player(Flashplugin.so) by GeneralCoffee(www.generalcoffee.com)
RealPlayer plug-in (plugin-Realplayer.so on BeOSR5 Pro version)
I installed by link these files to mozilla/dist/bin/plugins/ .

## remaining works
I set only MIME-types so far.
Descriptions and Extensions fields are left blank.

modified files:
  nsPluginsDirBeOS.cpp : modified nsPluginFile::GetPluginInfo() to read MIME types from plugin file's attributes
  ns4xPlugin.cpp : added BeOS implementation to ns4xPlugin::CreatePlugin()

this patch includes bug #67225 's  patch(id=23991)
Status: NEW → ASSIGNED
*** Bug 67225 has been marked as a duplicate of this bug. ***
Patches look ok so far. I'd remove the #ifdef DEBUG_edburns stuff though. Are
you planning on finishing the implementation (i.e. adding descriptions and
extensions) or leaving it as is?
I just implemented the remaining part.

I didn't know what format of "fExtensionArray" it should be when a mime has multiple extensions,
but after all, I figured out that it is comma separated, viewing source code. So I implemented as that.

I also set mime description and I believe I finished implementation. Can anyone review this patch?

Just so we are clear on this... the filling in of the field "info.fDescription" ( 
the description of the plugin) is still not implemented. I'm ok with this, as the 
patch is much better then what currently exists, but this should be taken care of 
at some point. r=bnesse.

Makoto: I followed your steps below, but couldn't get plugins to work yet - does
this work with build 2001022211 or do I have to compile from the latest sources?
Also, when your (brilliant!) patch is finished, it would be good to add a
"Help/About Plugins" menu that opens the page "about:plugins"...

This patch is not included in the official mozilla source tree yet.
So, to enable plugin, you should get source and patch to it.
Or, get a patched Bezilla binary from < http://bezilla.inetking.com >.

I think this patch is OK to check in.

As for the field "info.fDescription", I'm not sure the way 
I can get a description of a plug-in. 
So, if you know something about it, please tell me.

hmm.. the description is only for informative purposes, right? Why not hardcode
it in for now?
Another possibility might be to use AppFileInfo::GetVersionInfo() to get
version-number, short and long description of the plugin, if available.
For FlashPlayer, this would be possible, but RealPlayer does not have any infos
in the resource (because it's a library), so you could maybe fall back to
hardcoded information in that case...

The description is generally a 1 line string that the vendor adds describing 
their plugin. (It's a string resource on the Mac, probably on Windows as well.) 
Some random examples are:

RealPlayer(tm) LiveConnect-Enabled Plug-in
Shockwave Flash 5.0 r30
Adobe SVG Viewer for Macintosh
Macromedia Shockwave for Director Netscape plug-in, version 8.0

Plugins are detected now, but RealPlayer always crashes:

mozilla-bin:
Moving to m0.9.1. makoto, can you meet this milestone?
Target Milestone: --- → mozilla0.9.1
any progress on this?  getting down near the point where
we will need to move it off the 0.9.1 list if it
doesn't look like it can land soon..
looks like no one is watching this bug.  unsetting target milestone.
Target Milestone: mozilla0.9.1 → ---
This bug IS watched infact, and Flash is working nicely, only Real makes problems.
The Yahoo-link is outdated now, but here's another one:
http://www.ptv.at/pte2rpm.pl.cgi?ptanr=010503003

A video should be started but nothing happens after it's resolved - Opera
correctly launches RealPlayer (externally) but it doesn't handle the stream
("PNR_FAIL").
A big problem here is that the RealPlayer included with BeOS 5 Pro is very
outdated now (version 7 or so, < G2), and so many pages with Real-content are
not handled anyway.

IMO no target-milestone necessary until a newer RealPlayer for BeOS sees the
light of day. What's the appropriate verdict for such a bug-status?

Sorry, time has passed...
I tried to apply the previous patch and it worked with my bezilla 0.9.1+.
I can view Flash pages and listen to Real Player audios but videos can't be 
viewed because the Real Player for BeOS doesn't support the newer video format.

But this video problem is not in the scope of this bug.
Bezilla can successfully launch some plugins and play something. So this bug is solved.
Whether the launched RealPlayer can or can't play some formats is not in the scope 
of this bug. (IMHO)

I modified the method to set info.fName and info.fDescription. And I think this is 
good to check-in. please review it.

FYI: This ON24 page contains many links to RealPlayer audio/videos.
http://biz.yahoo.com/oo/

in ns4xPlugin.cpp, I think you should return NS_ERROR_FAILURE rather than 
NS_ERROR_UNEXPECTED. I see that Mac returns FAILURE, but WIN & UNIX return 
UNEXPECTED. I believe FAILURE is more correct, but I won't force the issue. Maybe 
av has input?

Otherwise, patch looks solid. r=bnesse.

I agree with Brian, but don't think this will affect anything. One other thing, 
Unix version does some 'fancy' job with different types of separators. I don't 
know whether BeOS needs it too or not. Anyway, r=av
Brian, Andrei, thank you for comments.
As for the 'fancy' job with different types of separators, I think it's ok so far, 
because that type of plug-ins aren't currently available on BeOS.

And... Chris, can you commit my patch?
Or, can I get the permission to do that?

The patch has been checked in.

Makoto, you need need to follow the directions at
http://www.mozilla.org/hacking/getting-cvs-write-access.html in order to apply
for cvs write access.
