I have a DVD that have three different camera view angles.
Is VLC able to switch the view ? I was not able to find this menu item.

Yeah, I've been looking for that as well. I only have one DVD that uses it, so it's not really much of a problem at all, but it would be nice to have that functionality.

Camera Angle in VLC

Can't seem to find a proper camera angle feature anywhere in VLC - running 0.85 under Mac OX . Surely the VLC geniuses have put it somewhere - are there any hotkeys?

Did you look in the Video menu ? I don't have any multiangle video here but i'm 99% sure that we have such an option (at least in the wxWidgets interface)

I just checked for that,
There is an option in the context menu under Navigation/DVD Menu/Angle
but when i click that it just jumps back to the main menu

Oh, so the option is there ... but it's just broken ?

If that so, please fill a bug report on http://trac.videolan.org/vlc/

It's Preferences, Input / Codecs, Access modules, DVD with menus and DVD without menus "Angle"

I have referred users here to change angle for what is played for their language so that a proper transcode could be obtained. In this particular case no option was offered within the DVD Menus for angle selection, it was automatic with the language. But I would suspect that if such an option were to exist, it would also work.

@ DJ:
PowerDVD has a button for that in (on?) the main interface and even a hotkey (a)... so your solution appears to be way too complicated.

@ dionoea
I tried to write a bug report but the "register" button seems to be broken, too :D
i'll try again tomorrow

There is always a selection in the DVD menu if it was intended that the user have this control. But if a angle selection is available you can right click in the screen and choose Chapter, Angle. If there is an angle menu or the feature is available it will appear.

well, 2 1/2 years later this feature is still broken... what's going on?

do I have to install a plug in or something to get the camera angles?

it's so frustrating, Windows Media Player gives the camera angles on the dvd but you get no sound, as if for some reason MS don't want you to play dvds on your computer...

VLC always works great, plays anything, with sound... but I can't get any camera angles on this dvd (which is a legit disc of 'McCoy Tyner, Guitars' jazz recording)

I have the same issue.
I own a "Remembering how to drum" DVD that has dual angle feature. It works in the home theater DVD player, but not with VLC.

To be clear, I wrote my post above because this just isn't true... there is no option in the DVD menu for this disc, and there are no options under Chapter > Angle.

However the DVD definitely has multiple camera angles because they work fine in WMP.

Yes there is. Navigation / Chapter / Angle. I don't know if it works as I have no such DVDs, but the menu is definitely there.

An "Angle" position is there under Chapter menu, but it seems a nonsense to me (what has this to do with a "chapter" ?) and further I don't know where to select the desired angle (stream, in fact).

I have at least two DVDs, one with main + 2 separate camera view (Phil Collins – Serious Hits... Live!) and another one with main + 1 separate camera view (NIN – Live, Halo seventeen).
Let's take the first one; how do I switch to camera #2 when at song The West Side, for example ?
Or – ok, I can select "Angle" (and it remains selected); so what ? I want to choose which angle.

(tested with VLC 1.0.0-pre2-20090429-2204 Goldeneye, Windows XP, opening a DVD with menu (opening a DVD with no menu crashes VLC instantly))

Try with another dvdnav based player. If it works, then it's a VLC bug. If it does not, then send a patch to the dvdnav guys.

I don't know what "dvdnav based" player means. I play the different angles of my Phil Collins DVD since years with Cyberlink Power DVD and also with my home physical (hardware) DVD player.

As for the crash when opening the DVD with no menus, it plays fine with VLC 0.8.6.

The DVD specifications are confidential. Open-source players are pretty much all using libdvdnav which is a reverse-engineering effort. Because of this, there are a certain number of bugs. Blame the DVD forum stupid licensing terms.

oh that's a shame, I didn't realise it all had to be reverse engineered, sorry! I guess this is why you have to pay for most dvd software. this also explains why I can't get sound in WMP. Microsoft's advice is to buy a 3rd party codec pack. amazing that it is such a successful format in spite of all this crapness! I guess people must really like watching movies

if I have time I will try on another libdvdnav player. the only one I could find for windows seems to be a special build of MPlayer. it all seems a bit hacky

What I can tell you is, that it works with xine, which is, afaik, dvdnav based.

It also works with mplayer, both using libdvdread and libdvdnav, but there seem to be issues. It switches to Angle -1 and then switching doesn't work anymore. That might be a mplayer problem, though.

Haven't found any possibility in vlc to switch the angle, so I guess it is not supported within the Qt4, at least.

It's supposed to be in Playback menu -> Navigation -> Angle -> ... but it is not tested for lack of content.

Well, just wanted to clear up the question, if it may be a libdvdnav bug instead of a vlc bug.

The menu you suggest doesn't exist, at least in the Qt4 interface. There is Playback -> Navigation -> DVD menu -> Angle, but that just drops back to the main menu and I guess should rather bring up the angles menu, if there is such a dvd menu for that dvd.

If someone knows one, yes.

According to Wikipedia, multiple angles are correlated to pornographic content. This may be (a large part of) the problem :!: As a developer, I would rather test with work-safe material.

I have seen some F1 race DVD with multi-angle, but I couldn't get a copy.
