I think this happens in 4.x too. Where are the plugin DLL's to copy to our 
plugins folder?

Shrir, have you been able to get this to work in Nav 4?

Comment 6 User image Peter Lubczynski 2001-01-26 16:35:17 PST
The first attached DLL (#23279) didn't work at all for me. I think something was 
wrong with the MIME type so I attached the one on my system (#23593).

From the testcase I've attached, I can see that the plugin is trying to go back 
one page by asking for the url: javascript:history.back(). Some other weird 
stuff is going on as well.

marking as dogfood, this meets the new interpretation of dogfood.
Also ressummarizing, as it doesn't really matter that the window is opened via
javascript. Windows Media Player just doesn't work in Mozilla. tested using
win2000 build 2001022105.

This could be a LiveConnect.
Comment 12 User image Peter Lubczynski 2001-03-01 15:43:30 PST
This is not a LiveConnect issue (at last not totally) because my testcase works 
in 4.x if Java and Javascript (effectivly LiveConnect) are turned off.

I don't think this is right dependency. What 73856 is about will require 
rewriting the plugin itself. So this will not help with the existing media

todd: what we have here is a situation where we'd like these folks to rewrite

you give me a contact to write to there?  i can send them av's latest write up
on scriptability.

I went to:

instructions on that page to install a Netscape plugin. I restarted my browser,
and then went to:

I did something wrong in the steps above which would not have triggered the bug.

Comment 30 User image Peter Lubczynski 2001-07-27 17:23:43 PDT
Update from Arun K. R. logged in as peterl (we're at a conference).  Windows
Media Player works as a helper application. Can a quick workaround be to have
MSNBC detect our user-agent, and then invoke their media player as a helper
app.?  if so, it bypasses ugly plugin issues.  This requires high level contacts
at Microsoft; chrisn, can you give it a shot?

Comment 32 User image av (gone) 2001-07-27 19:35:47 PDT
Maybe it works for because for w2k you have the newer version 7.1 while it is 
not available for NT40, the latest there is 6.4. Your url doesn't play for me on 
Comment 33 User image Peter Lubczynski 2001-07-27 20:20:30 PDT maybe it is a version problem just on NT 4. I just tired the test URL
on a Windows XP machine, and it played and worked for me fine. This is a valid
bug for NT 4, but I don't think so on Windows XP or Windows 2000. Can anyone
confirm my results?
Comment 34 User image Arun Ranganathan 2001-07-28 12:53:09 PDT
This appears to be a WinNT4.0 *ONLY* bug.  I just tested on Win98.  In fact, I
went to the website, obtained the plugin by clicking on the 
'plugin not found" link, went to microsoft's website, and downloaded Windows
Media Player 7.1.  Here's the *astounding* thing.  It appears that Media Player
7.1 has an installer that recognizes N6.1 -- could Microsoft know about bug
77244 ? :-) More to follow.

I am not a windows media preferrer but I found another page.

Go to (Yahoo one), it will test the plugins, dispay
versions greatly and correct.

When test finishes, broadcast popup window (they made kind of a browser via
javascript) opens. I was also happy to see wmedia player there (I saw the
plugin, it allocated its space perfectly) than NS 6.1 Final told me "This plugin
generated errors" than crashed

Since Yahoo Broadcast is a major site I wanted to note this quick.

Win2k pro here with wmedia 7.1 (netscape plugin installed)

PS: Reported to Yahoo too

Susie, pls download the latest 7.1 version on 98 or 2000. The link you 
mentioned and also the video links on this page work great on 2k.Thx!
Comment 39 User image shrirang khanzode 2001-08-09 10:36:33 PDT
Arun, I downloaded the media player with 6.1 candidate build..but the installer 
did not put the plugin in my 6.x plugins folder..hmm. I had to manually copy it 
from 4.x
Comment 40 User image shrirang khanzode 2001-08-09 10:58:01 PDT
the video links here give the error message of 6.x not being supported:

Comment 41 User image Benoit 2001-08-13 09:34:36 PDT
This happens with Windows 95 too. Windows Media Player isn't available in any
version higher than 6.1 for this operating system. The installer for WMP 6.1
(Win95/NT4) installs the plugin in the 4.x directory only.

I've tried to copy the npdsplay.dll to my mozilla directory (0.9.3), the WMP
plugin is then listed in "about:plugins" but :
- On the testcase, I get the
window, the box containing the video resizes and then the browser goes back TWO
pages back in his history.
- When I try the url at msnbc, the window opens but i don't see anything where
the video is supposed to be.

Comment 44 User image Arun Ranganathan 2001-09-05 11:10:49 PDT
Here are questions/comments:

1. I know that the Yahoo folks are using the scriptability of plugins such as
WMP, and therefore, since WMP is NOT scriptable owing to architecture dependent
on LiveConnect, it doesn't work.  MSNBC also use the scriptability of plugins,
and thus it won't work there, but yet they have *other* pages which do not
script the plugin.  These pages work fine.  I'm sure MSNBC can be accomodating .  

2. The Player 7.1 installer *should* install to N6.1 correctly.  Shrirang, was
this NOT the case?  I tested on Win98 and found that installation was correct. 
What did you test on?  Note that if you tested on WinNT or Win95, you would not
find this to be the case.

3. Has anyone else reproduced the crash noticed by Ilgaz Ocal on O8/08/01 above?
 If so, this crash could be a 4xp crash and should be logged separately.
Comment 45 User image shrirang khanzode 2001-09-07 09:15:05 PDT

Just tried the 7.1 media player installer on a win 98.
Arun, the installer *does* install in 6.1 after a machine restart.

The testcase, and other links in this bug work fine. I do not 
see a crash. However, the links on this page(as mentioned earlier)

do not work. 'Browser not supported' error is seen. 

All those who have mentioned their issues in this bug, pls retry with 7.1 media 
player and a recent build. does not crash anymore. The Media helper correctly 
detects the players on my system and lists them.However, trying to change 
preference to realplayer does not work and media player launches even when I had 
selected realplayer...I am filing a new bug for that.

So ,what do we do with this bug? fxd, wfm ?
Comment 46 User image Arun Ranganathan 2001-09-07 13:06:40 PDT
shrir, could you test on Win2k as Ilgaz Ocal suggests above using Windows Media
Player 7.1?  We're looking for a crash and some tangible "machine data" of a crash.
Comment 47 User image shrirang khanzode 2001-09-10 12:51:17 PDT

Comment 48 User image David Walker 2001-09-12 15:58:19 PDT
Hi, I'm an occasional reader of these pages and would like to point out that 
there was some version number-related confusion in this bug commentary. 

Benlu's 8/13 post pointed out that "The installer for WMP 6.1 (Win95/NT4) 
installs the plugin in the 4.x directory only."

Arun then apparently miscontrues this on 9/5 and asks a question, to which 
shirang points out on 9/7 (correctly) that the 7.1 media player installs 
correctly on Win 98 into the Moz 6.1 directory.  This is true but unfortunately 
irrelevant; the Moz 6.1 directory is not the WMP 6.1 player. 

The next-to-last post asks for retests with WMP 7.1 (not available for Win95 or 
WinNT 4.0).  Still not addressed is the fact that WMP 6.1, the most recent 
available for Windows NT 4.0 and Win95, doesn't install into the right Mozilla 
folder.  Retesting with WMP 7.1 won't help this.  NT 4.0 users can use WMP 6.4, 
I think, but Win95 users are stuck with WMP 6.1.

Thanks, hope this helps.

trying here on XP Pro, mozilla 0.9.8

media player plugin does not work at all. Just shows a black screen where it
should appear.

tried with asf and avi.

unzipped manually the files from wmpplugin.exe (microsoft page) to plugins dir,
and tried the dll posted here as well (same file??). Plugin is listed on
help:about plugins, but shows only a black screen.

oh, and on yahoo streamer, it lists as media player 6.4 (XP has the 8.0 or XP
version)... but I think that is to be expected.

WFM on Windows XP Pro on the trunk (did not try 0.9.8) viewing videos on
with Windows Media Player 8.0.

Copied np*.dll from c:\Program Files\Windows Media Player

Can you post a testcase with detailed steps to reproduce the problem?
Comment 55 User image Leonardo Morelli 2002-02-06 13:38:14 PST
okay Peter, that works.

shouldn't Mozilla, when installing, find these files and copy them, or maybe
microsoft perhaps be more friendly and just make a plugin installer for that?
...cause when you go to the media player download page, they say "well buddy,
you have windows XP, so you don't need to download anything"

anyway, that's a design decision perhaps

sorry about the false alarm

Associated class files for WMP7 plugin

Plugin does not work on Windows 2000 [build 2195]. Plugin buildspace appears,
along with Windows Media Player logo (where video would display) and controls,
but controls are inoperative and nothing plays (also, no status). Have tried
several different configurations (and levels of extraction of the associated
WMP plugin files NPDS.ZIP and NPDRMV2.ZIP) but to no avail.

Windows: 5.00.2195 [Windows 2000 Service Pack 2]

There are also several Java (CLASS) files that are included with the Microsoft
plugin. I'm creating an attachment with decompiled versions (oops,
reverse-engineering M$ products, bad me). Perhaps they'll shed some light on
the problem.

Tested and reproducible:

Some testcases can be related to bug <a

a clunky Javascript command that [sh,w]ould redirect the window to a page that
says "Upgrade your browser").

opens and Mozilla window bugs -- it displays what was last on the screen (can
someone describe this better, please?). [eg. <a

Shouldn't crash & WMP 6.4 be added to the summary & "NT and 95 only" be removed,
since bug 148483 was marked a dup of this? Also, it's not so much an NT/95 issue
as it is a WMP 6.4 issue. As per my initial report in bug 148483 & bug 148483,
comment #2, this bug not only crashes MozRC3, but Netscape 4.79, as well. It is
seems to be related to the fact that Mozilla is not backwards compatible with
LiveConnect-supporting scriptable plug-ins, but given that 4.79 will crash, I'm
not 100% positive...

if someone doubts: I'll create and attach a screenshot.
However, I downloaded that cabfile manually, unpacked it with WinAce and what i
found was an inf file (I will attach it, too.)

didn't show the movie but, on right click, it had an option to tell you
something about an error.)

Sounds like this isn't quite resolved yet for everybody. Is there more that
needs to be done here? Nominating for RTM to get some traction on this one.

i think my bug(at least the new one) is not that on that this was in the
begining, i think bug 151772 could be the right place to track it (?)

WinXP Professional with Media Player 8.0 and Mozilla 1.0 - worked fine.  After
upgrading to 1.1, stopped working.  Verified np*.dll files were in plugin directory.

Downgraded to 1.0 and Media Player plugin worked.

thats right this bug (asking about the x-oleobject plugin) is new and only on
the 1.1 trunk , but i was unable to utilize embeded wmp on win98SE  with wmp7.1,
do i still have the wrong plugins or is this only working on WinXP with 1.0?

MS does not support Win95 anymore and Win NT in VERY VERY VERY few cases (and
not in this case!!) so isn't this a won't fix.
-As anything else discribed here is not this, but another bug.

No,IMHO, because we shouldn't exclude users from Mozilla just because Microsoft 
considers they systems obsolete. If DOS weren't completely dead, then it would 
be cool to drag Mozilla onto DJGPP. Then you could have a Mozilla boot CD to 
run it on a computer with no operating system. ;-)
Comment 82 User image Jan M 2002-07-05 04:37:23 PDT
users on win95 and winnt will still be able to use mozilla
but the plugins will not be updated for wmp6.4!(As there is a a newer wmp for
the other versions of Windows.)

-------this is not bug related and should be discussed elsewhere!--------
and: yes running on dos would be cool, but dos is an operating system (the full
name is "Dirty Operating System!)
you can run mozilla from cd anyway, if you use linux(there are distros that run
from cd)

based on plug-in team triage, this is a wfm - Shrir can you please verify that
this is truly fixed

Confirming WORKSFORME - Windows 2000, 2002072918, WMP7.1 (with IE6 update).
Did not work previously.

Two things may have resolved this:
1) work from Mozilla team
2) the Windows Media Player update that comes with IE6

Reopening..Lets straighten this out.

1) 7.1 or greater (seems to be with the latest security patches) does work if
you copies files into your plugins directory as directed to by

2) 6.4 still does *not* work what ever version. The reason this is still
important is because 95 and NT do *not* have an upgrade to 7.1

3) when putting the npdsplay.dll npwmsdrm.dll file into the plugins directory
the file starts to load then suddenly it returns you the previous page.

I am reclosing this bug, please do not reopen this bug, rather open a new bug
for new issues.

>> right, this is an issue with the WMP plug-in. If the vendor developer
(Mircosoft) determines that they are not supporting a platform, then that is
their decision alone. We cannot override that decision, nor should we.

2) 6.4 still does *not* work what ever version. The reason this is still
important is because 95 and NT do *not* have an upgrade to 7.1
>> in the current released versions, version 6.4 does work in regard to the
original reported issue.

>> if this is the case, then you would need to open a new bug, include a test
case and provide the plug-in data and tested build data (current versions of the
browser, older versions of the browser will not be modified).

The Plugin api function NPN_GetURL does not handle urls of the form: mms://
