When trying to watch

I get

[Comment 1 Rafał Mużyło 2011-03-30 12:30:49 UTC]

Well, it's a xulrunner 2.0 problem, obviously.

A quick google suggests, that those two functions can be simply removed.

[Comment 2 Rafał Mużyło 2011-03-30 12:31:41 UTC]

By two, I mean NPP_Shutdown and NPP_Initialize.

[Comment 3 Rafał Mużyło 2011-04-10 18:39:39 UTC]

I think I see the real problem with this bug: mozilla plugin is only in vlc-1.1 branch, not in the to-be-1.2.

[Comment 4 Rafał Mużyło 2011-04-10 18:51:32 UTC]

Correction: the code was separated a few months back to http://git.videolan.org/?p=npapi-vlc.git but there were no significant moves since then.

[Comment 5 Rafał Mużyło 2011-04-14 11:32:51 UTC]

I don't see any fixes for this problem in 1.1.9.
It's probably still broken.
A little surprising, as a couple of mime fixes for the plugin did get in.

[Comment 6 Rafał Mużyło 2011-04-14 16:02:04 UTC]

Created attachment 269963 [details, diff]
patch for the plugin

Could somebody test the following patch ?
Obviously needs to be combined with
mv projects/mozilla/support/npunix.c{,pp}

Changes, as you may tell, are trivial, especially that in npmac.cpp Private_SetValue already has such signature.

[Comment 7 Orivej Desh 2011-05-09 21:26:25 UTC]

Yes, this fixes the problem, thanks.

[Comment 8 Paul Tobias 2011-05-14 18:20:59 UTC]

Yes, Rafał's patch fixes the problem for me too.

[Comment 9 Richard 2011-05-20 16:43:11 UTC]

This also affects Google Chromium:

/usr/lib64/chromium-browser/chrome --type=plugin --plugin-path=/usr/lib64/nsbrowser/plugins/libvlcplugin.so --lang=en-US --plugin-data-dir=/home/richard/.config/chromium/Default --channel=31056.0x5f20200.55425446: symbol lookup error: /usr/lib64/nsbrowser/plugins/libvlcplugin.so: undefined symbol: NPP_Initialize

Patching browsers to resolve this seems to be like playing whack a mole to me. It might be better to implement stubs for these functions in the plugin itself.

[Comment 10 Richard 2011-05-20 16:55:14 UTC]

Please disregard my previous message. I misread the patch as being one for Firefox. It is now clear to me that it is a patch for VLC. I will test it later.

[Comment 11 Alexis Ballier 2011-06-22 12:41:13 UTC]

this should be fixed in 1.1.10, please reopen if not
