OSX: Windows Media Plug-in fails on initialize
Build: 2002-01-08-08 Platform: OS X Expected Results: Windows media content should be played What I got: Missing plugin icon is displayed on page Steps to reproduce: 1) Install Windows Media Player for OS X (from microsoft's mactopia.com site) 2) Windows Media plugin installs in the Library/Internet Plugins folder 3) Launch Mozilla 4) Go to About Plugins under Help menu. 5) Notice Windows Media Plug-in is identified in window. 6) Go to a site like CNN to watch to windows media content. 7) Instead of content being play by the plug-in, the missing plug-in appears.
confirmed on 0108 trunk , OS X

Summary: OSX: Windows Media Plug-in not recognized in browser → OSX: Windows Media Plug-in fails on initilize
Here's the problem. We load the new "Windows Media Player" plugin using the CFBundle APIs in our implementation of PR_FindSymbol(). However, the plugin is not a mach-o binary but a CFM/PEF binary, and it isn't exporting a |main| symbol. There are a couple of workarounds for this: 1. Microsoft changes the plugin and exports main for us. 2. We load the plugin using CFM calls, rather than CFBundle calls, and we'll likely be able to get the main entry point from our call to GetSharedLibrary(). This throws us a real curve. Apple's Quicktime plugin has the courtesy to export its |main| symbol. There is one other possibility, the media player plugin does export its plugin entry points: ------ Loader Export Symbol Table ------ Section Address Class [Hashword] Export Name 003858 [ 0] 1 00005F34 TVector [000EE0E5] NPP_Initialize 003862 [ 1] 1 00005F0C TVector [000DF0F7] NPP_NewStream 00386C [ 2] 1 00005EDC TVector [000FD76C] NPP_HandleEvent 003876 [ 3] 1 00005F24 TVector [00071FFD] NPP_New 003880 [ 4] 1 00005F14 TVector [000DECBD] NPP_SetWindow 00388A [ 5] 1 00005F04 TVector [000EC23D] NPP_WriteReady 003894 [ 6] 1 00005EF4 TVector [0011F98B] NPP_DestroyStream 00389E [ 7] 1 00005F2C TVector [000CF77C] NPP_Shutdown 0038A8 [ 8] 1 00005EE4 TVector [00097E7C] NPP_Print 0038B2 [ 9] 1 00005EFC TVector [00097E29] NPP_Write 0038BC  1 00005F1C TVector [000BFFDE] NPP_Destroy 0038C6  1 00005ED4 TVector [000DFC85] NPP_URLNotify 0038D0  1 00005ECC TVector [0010D961] NPP_GetJavaClass 0038DA  1 00005EEC TVector [00101E39] NPP_StreamAsFile We could conceivably work around this problem by manually looking up these exported entry points, and filling NPPluginFuncs callbacks with the results.
Unbundling the plugin does allow it to load. Loading the CFM library to get the main entry point is starting to sound attractive.
This patch is an attempt to load the entry points directly if they are exported from the plugin. However, it doesn't seem to work, because NPP_New() crashes. I think their main routine is doing some initialization that isn't happening otherwise.
With this patch to NSPR in place, the "Windows Media Plugin" does load. The patch loads a CFBundle's underlying CFM executable using GetDiskFragment. This is a hack, but I know of no other way to do this.
Now that the plugin loads, it exposes another bug. If I attempt to load the following URL: http://www.kqed.org/streamingfiles/kqed_wmp.asx for some reason the plugin keeps attempting to launch the "Windows Media Player" application over and over. I have a feeling that we are handling some error condition the plugin is generating in an incorrect way.
-->beard That full-page problem could be related to: http://bugscape.netscape.com/show_bug.cgi?id=11600 There is a patch in that bug that checks for the error that WMP (at least on windows) returns.

I have confirmed that this bug is still active in the Mozilla 1.0.0+ Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en-US; rv:1.0.0+) Gecko/20020522 release ... Windows Media player does not work, but Quicktime works fine
yeah , this has been added to the release notes.

Has anyone verified whether this bug also occurs in Netscape 7.0? I usually avoid sites which use the mediaPlayer, but will try Netscape.
Yes, I try with Netscape 7 and it is the same problem. Windows Media Player Plugin was not recognized and not work.
What's the current status of this bug? Will we have a final patch before it's too late?
The bug is due to Microsoft's implementation of the WMP plugin. Since I have no idea how one goes about directly evangelising M$ we've asked our Apple liason to forward this bug to his counterpart that deals with M$. No progress to report there yet.
lowering the impact per discussion in the adt.

Just to reiterate for folks that didn't see beard's comment for the patch he posted to try and load the WMP plugin - it still doesn't work right. WMP works in _no_ OS X browser but IE. If you want that changed lobby M$ to fix their plugin as us trying to hack around their non-standard plugin implementation for WMP isn't the 'right' solution.
--->reassign to beppe Microsoft needs evangelizism help to follow the NPAPI on OSX like all other plugins.

Is there any feedback Mozilla can provide to the user in these circumstances to make it apparent that it's MS's fault, and not Mozilla's?

http://wwwa.accuweather.com/adcbin/flavideo/video.asp?video=763126 Plugin doesn't load. Windows Mediaplayer under build 2002101612. It loads in Explorer for X.
Pardon my vernacular but no shit! Do you think this bug would still be open if it worked?
We are working with WMP folks to get it to work with NPAPI This is not a mozilla bug, removing nsbeta1+ and topembed+

I just noticed with Safari that it redirects the content to the Windows Media Player application. To test, go to News.com and click on one of those videos. You will notice that Safari notifies you that the plugin is not supported and asks you if you would like to play it externally. Pretty interesting...

Good news; plugins now work with Windows Media Player version 9 for OS X. A quick test at http://www.msnbc.com/ confirms this with Mozilla 1.5 for Mac. http://www.microsoft.com/windows/windowsmedia/software/macintosh/osx/default.aspx
Now that Microsoft released a Mozilla compatible version of the WMP plug-in this bug is no longer valid.
