Hi all,
I'm trying to create a XUL application which is mainly a Video viewer which uses VLC plugin.
I think followed all instruction from Mozilla Gecko documentation and VLC site I put "npvlc.dll" and "vlcintf.xpt" into Xulrunner plugin folder but plugin did not started then I put also "libvlc.dll" into plugin folder and application seemed to start but no video was displayed.
Looking at error log it seems it can not find access_demux module for http! Here follows Error log and XUL snippet

I'm using gecko 1.8 and vlc 0.8.6a

Any ideas?
Marco.

XUL snippet:

There is an update, I changed VLC version 0.8.5 and something changed too.

Now according to log console everything starts right. But no video is displayed. Previous error maybe was caused by the fact that in 0.8.6a version plugin api changed.

Is this true? Any ideas about the fact that no video is displayed? On the other hand in Mozilla Firefox everything works fine and I can see the video.

If the system you want to run the webapplication on doesn't have VLC installed, you'll also need to copy over the content of VLC's plugins map. There's a lot of stuff in that map you won't need (like interface stuff for VLC player) but if you want to cut down on size you'll have to find out yourself which files are needed.

By the way, as far as I know vlcintf.xpt isn't needed anymore since VLC plugin 0.8.6.

Beware of these bugs for your webapplication though:

(bug #900)
VLC plugins versions after 0.8.6-test1 don't work with portable/mobile Firefox. So they can't be used from memory stick/dvd.

(bug #908)
all 0.8.6 tests and final will often crash:
- if reloading a page while the VLC plugin is playing video
- if you try to display: none; after having played (or are still playing) a video
(try visibility: hidden; if possible instead)
- if you try to close a browser tab while video is playing

(bug #1008)
the VLC object won't reappear after having used 'display: none;' twice

don't place multiple VLC within the same page (dont know the bug #)
this one I didn't find myself, because I don't have a need for two VLC players in my webapplication. But from what I read the two VLC objects will influence each other (and cause crashes)? One of the developers mentioned creating multiple VLC objects within Javascript works more reliable. However forget this if you only need one

.

(not reported yet)
using fixed positioned content and at the same time causing reflows (with updating the playtime or progress bar) can cuse VLC's playback to stutter. so better not use fixed positioned stuff.

(not reported yet)
with the Mac plugin + Firefox (not opera or safari), and some absolute or fixed positioned content(? have yet to figure out the exact cause), the 'no video' message and it's black background are drawn on the wrong location in the page. Playback happens at the correct position though.

(only tried on my own computer)
on Windows moving a window over a playing video will draw grey boxes/lines in the video??

The 0.9.0 nightlies have some more problems, so I wouldn't touch those yet.

Posted: **22 Jan 2007 12:26**

Finally using version 0.8.5 no more problem were displayed. And I can see the streamed video. Any way much of the problems seemed o be caused by XULRUNNER implementation: in some mail from mozilla.dev community I found also some workaround which claimed to use embedded html files as developers from songbird project did.

In future I will try to use 0.8.6a plugin and apis.

Anyway thank you for your anwers and for all your tips about bugs.
Marco.

Can you tell me how you did it works with 0.8.5 ?
XulRunner doesn't find the plug in when it's 0.8.5 and with the 0.8.6a it doesn't play anything.
In add, if I put -console to have the debug the plug in is not recognize.

Posted: **27 Jan 2007 19:25**

there is a post on my blog about the solution. http://www.marcobazzoni.it/2007/01/27/xul-vlc/

Hi to you all,

Iam trying to get VLC plugin working in xulrunner but i still have problems, no video is showing even with the solution from thebaz73.

xulrunner 1.8 and vlc 0.8.5 xulrunner 1.9 and vlc 0.8.6 i even try to use the vlc code from songbird. If i try the xul file in firefox it works and i see that the plugin is loaded in xulrunner. i get a dos window with the output of vlc

Iam trying to make a standalone xulrunner applicatie (Windows) that works like a TV with channels to connect to live streams. Can someone help me with this or has a working example for me.

Thanks

Hi sdaams, hi all,
I've posted a zip of my working solution in my blog
http://www.marcobazzoni.it/2007/01/27/xul-vlc/

Posted: **31 Jan 2007 15:17**

Thanks thebaz73 for your zip file. But still i can't get a video display. I try to display a videofile direct in the chrome directory. With the -console parameter i can see that VLC is used but display only Black with '[no video]'

Code: Select all

		
      <html:embed type="application/x-vlc-plugin"
	    id="vlcviewer"
	    name="vlcviewer" 
	    autoplay="yes" 
	    loop="yes"
	    flex="1" 
	    width="400" 
	    height="300" 
	    target="test.avi"/>

If i load xulvlc.xul i firefox it will play, so i think the problem is with xulrunner and the vlc plugins. Do you need to install VLC complete before you can use the plugins ? Or is it possible use only the plugins voor mozilla. What kind of version of Xulrunner and VLC plugin you used ?

I try Xulrunner 1.8 with VLC plugin 0.8.5 and Xulrunner 1.9 with VLC plugin 0.8.6. Perhaps you can zip your xulrunner with the vlc plugins and put it all so on the net. I lookd at songbird and try the VLC plugins that songbird is using but still i can't get it to work ;-(

Thanks thebaz73 but it doesn't play any video, I still have a black display with no video written.
How did you display the log? With -console the plugin isn't recognized for me

Posted: **31 Jan 2007 16:07**

It Works !

I created a directory vlc-plugins in the xulvlc directory and put all the vlc plugin files into this directory. In the xulrunner plugins directory you put
npvlc.dll and vlcintf.xpt.

If you what to display a video file instead of a stream us src='' and not target=''

I used xulrunner 1.8 and VLC 0.8.5 and its running

Hope this will help

Jeff

If have made a zip file with xulrunner and xulvlc and put it on the net.
let me know if it works !

Unpack this zip into your c:\ and start run.bat insite the xulvlc directory.

Here is the link
http://wiki.xulrunner.nl/xulvlc_xulrunner.zip

Thanks, I will try this but I would prefer it works with the 0.8.6a version

Posted: **31 Jan 2007 16:35**

Hi XeNaToS,

I try it with 0.8.6 but i will not work. But if you get it to work let me know. Or you can try with the guys from songbird. Look at there software trunk.

Posted: **31 Jan 2007 16:42**

I have tested with their own plugin vlc but it doesn't work too.
If I found a solution I will post it here.

Posted: **31 Jan 2007 16:53**

Does the zip file i made work on you system ?

Posted: **31 Jan 2007 18:01**

I will test tomorrow morning

Edit : It works

Posted: **12 Feb 2007 09:19**

This problem is only on windows. Under linux I have no problem with XULRunner and mozilla plugin 0.8.6a.

Posted: **12 Feb 2007 20:31**

In win32 I have managed to make XULRunner 1.9a3pre and the newer 0.8.6a version of VLC run but it causes weird problems with the profile system.

To start I put npvlc.dll (came with vlc 0.8.6a) in xulrunner\plugins. Looking threw the debugging it looked like it wanted the vlc\plugins folder to be located at the root of the working directory just ouside the xulrunner with the application.ini after that it found all the new plugins and created a cache directory of vlc under Applicaiton Data\<user>\vlc. and the application starts and loads the test content. The problem happens after I close the test app.

xulrunner creates a default profile for the working application under Application Data\<user>\<application name>. If I try and relaunch the app it loads but does not load either the plugins properly or something ells thats as much as I can figure out. If I delete the profile so it has to rebuild it next time its run it will play the video again.

Don't know if this is going to help narrow the problem down but it seams weird that the profile directory is what causes it to load incorrectly the next time the app is run.

Edit:
I have also installed VLC 0.8.6a with both Mozilla and ActiveX plugins for win32.

Posted: **12 Feb 2007 20:59**

in 0.8.6, the mozilla plugin is now locatable through registry settings as documented in http://developer.mozilla.org/en/docs/Pl ... d_Solution.

I'm surprised that xulrunner is not able to load the plugin; firefox seems ok with that. Maybe you need to use a syntax similar to the one documented in http://developer.mozilla.org/en/docs/Pl ... al_Benefit
