Description Julian Sikorski 2008-08-15 07:55:38 UTC

Description of problem:
Recently I was testing the latest labs.adobe.com flash plugin 10.0.0.569. I was pointed by abobe folks that to have better experience I should be using firefox trunk, and so I did. It turns out that there are some problems with the wrapper when wmode is coupled with flash video - the embedded video is not displayed. Using the i686 build of firefox solves the problem. The following message is displayed in the console with x86_64 build and the wrapper:

*** NSPlugin Viewer  *** ERROR: could not reconstruct XVisual from visualID


Version-Release number of selected component (if applicable):
flash-plugin-10.0.0.569-release.i386
nspluginwrapper-1.1.0-5.fc9.x86_64
nspluginwrapper-1.1.0-5.fc9.i386

How reproducible:
always

Steps to Reproduce:
1. Install the packages listed above
2. Get a firefox nightly build (I was using 20080814)
3. Go to e.g. http://politbiuro.pl/politbiuro/1,85402,5580837,Prezydent__Nie_boje_sie__Pracownik_BOR_u__To_glupota.html
  
Actual results:
White spaces are displayed where two video clips should be embedded

Expected results:
Videos are shown properly

Comment 1 Martin Stransky 2008-09-17 08:07:51 UTC

It's going to be fixed in the upcoming firefox update (3.0.2).

Comment 2 Julian Sikorski 2008-09-17 08:47:52 UTC

That's with 3.0.2 build 6. Error still present. Looks like nspluginwrapper issue to me since without the wrapper videos display fine. (Sorry it's ASSIGNED, I can't switch it back to NEW).

Comment 3 Julian Sikorski 2008-09-17 08:57:33 UTC

Looks like now I can. Please note that now I am testing with flash 10.0.12.10. I also tried 20080916 trunk firefox build and the problem is still present, but only these two errors are displayed:
*** NSPlugin Viewer  *** ERROR: could not reconstruct XVisual from visualID
*** NSPlugin Viewer  *** ERROR: could not reconstruct XVisual from visualID

Comment 4 Martin Stransky 2008-09-17 09:05:50 UTC

This error message means that the flash-plugin is recently dead. 

The firefox/nspluginwrapper combination support windowless flash plugin, but the windowless flash can crash as well as the windowed one and when this happens (very often) you'll see this message. 

It has nothing to do with the windowless mode, it's just a flash crash.

Comment 5 Julian Sikorski 2008-09-17 09:08:40 UTC

Then why it does crash with nspluginwrapper disabled and works fine without it? Do you want me to carry out some additional tests?

Comment 6 Martin Stransky 2008-09-17 09:14:30 UTC

Flash crashes with nspluginwrapper because the NPAPI emulation provided by nspluginwrapper is not 100% accurate. Unfortunately we can't fix it reliably because there are some limitations given by the RPC interface architecture and closed-source flash code...

Comment 7 Julian Sikorski 2008-09-17 09:30:54 UTC

Well, I guess no WMODE for me then until Adobe releases a 64-bit plugin. CLOSED CANTFIX?

Comment 8 Julian Sikorski 2008-10-16 18:16:34 UTC

This seems to have been fixed with the latest update. Way to go folks!
