I am using VLC as a plugin for Firefox and tuning into TV broadcasts using UDP. I have recently upgraded to version 1.1.1 and I am now getting a problem when the TV aspect ratio changes.

If I am receiving a 4:3 broadcast then the picture is nicely centred on the screen and looks great. The broadcast then goes to a commercial break, and the content switches to 16:9. Once the broadcast returns from 16:9 to 4:3 then the problems begin.

The 4:3 content gets shoved off to the left of the screen leaving a horrible white space on the right. If I change playlist items at this point to another TV stream, one that is in 16:9, the new content gets squeezed into the 4:3 box and does not resize.

I have some pictures to highlight what I'm talking about:
1) This is the content playing normally in 4:3 mode: http://imgur.com/Ebh51.jpg
2) This is a 16:9 advert kicking in: http://imgur.com/kQWBp.jpg
3) This is what happens the aspect ratio goes back from 16:9 to 4:3: http://imgur.com/qhuo0.jpg
4) This is when the playlist item is changed to another channel: http://imgur.com/wcS02.jpg

This bug was not a problem in the 1.0 branch. It is only since I have upgraded to 1.1 that the bug has manifested. Does anyone know if there is a workaround for it?

PS: I have a raw dump of an DVB-T stream that reproduces the bug reliably. The file is 20MB and I can post it somewhere if anyone is interested in recreating the problem.

EDIT: Could this bug be a variation on this one already reported? https://trac.videolan.org/vlc/ticket/3848

Ok, so obviously I'm posting this bug in the wrong place. Either that or nobody is concerned that the 1.1 branch has a huge problem with the Mozilla plugin. Can someone please direct me to the correct place for reporting this bug?

Are you using Mozilla on Linux or Windows ?

From a quick look at the source code, this problem described in the trac system should only occur on the Linux port.

Hi erwan10. I'm using it on Linux that's right. I noticed that you've submitted a patch to the Trac bug above. I've tried this on my system and it seems to have done the trick! There is an error that gets logged "Failed to resize window", but I presume that is the desired result.

Thank you very much.

nobody is concerned that the 1.1 branch has a huge problem with the Mozilla plugin.

That's mostly correct. The maintainer of the two web browser plugins has left about two years ago. Nobody stepped up since then.
