Problem with Button Over Video and Multi-Angle

[Crazyjoe]

Hi Folks!

Currently I'm working on a project where I implement a "white rabbit" feature, but I'm encountering some problems. I'm working with Scenarist.

Before the main movie plays I display a short clip (4 seconds) with either the german or the english title (depending on user selection) and with the white rabbit feature either turned on or off.

Both, the "title clip" and the main movie are in the same PGC, but different tracks in track editor.

The layout in track editor is as follows:

Track 1: "title clip" with 4 Angles ->
Angle 1: english title, "white rabbit" subs (forced start),highlight layer
Angle 2: english title, dummy subtitle (shouldn't display white rabbit in this angle), not forced start
Angle 3: german title, "white rabbit" subs (forced start), highlight layer
Angle 4: german title, dummy subtitle, not forced start

Track 2: main movie, dummy subtitle track

Track 1 lasts exactly 4 seconds. Depending on the subtitle and highlight display times I tried both, same duration as the video and start short after beginning/stop short before end.

In scenario editor I combine these two into on PGC. No problem so far. Simulation in Scenarist works (but which simulation wouldn't do that in Scenarist ;) ). The problems start when testing the disc outside Scenarist:

PowerDVD: no "white rabbit" sub is displayed; button is usable only in the first second of the clip, after that impossible to activate.

WinDVD: no "white rabbit" sub is displayed; button is usable during the whole clip (4 seconds).

Standalone Player (Pioneer 525): "white rabbit" sub is displayed, but no button is useable.

Can someone please tell me what is going wrong? :confused: :(

EDIT:

Two more things:

First, what exactly do UOP0 (Time_Play()) and UOP2 (TitlePlay()) prevent?
And second, in the PGC properties of that PGC I can't see any subpicture streams listed in the "subpicture attributes" section, altough both the multi-angle part and the main movie have a subtitle track (see above). :confused:

I think your dummy subpictures need to have forced start too. Also, it sounds like you've set the angles to non-seamless, right? So far I have only reauthored one multiangle title with button over video (seamless angles) and it worked out just fine.

Hm....that might be. I will try that today and post my results.

Last night I came to a weired behavior. For testing purposes I deactivated the subpictures availability flag in that title - completely forgot about that. After adjusting the maximum number of streams again, the subpicture finally was displayed on PowerDVD and WinDVD.

But the odd thing is, that the standalone displayed them already. And I always thought, that the availability flag only "hided" certain streams from the user, but wouldn't make them actually invisible for the player (see the behavior of PowerDVD and WinDVD).

And still there is the problem, that the button is normally useable in WinDVD, but shows only up for the first second in PowerDVD.

I haven't tested it so far on the standalone, but will do so today.

Thanks for the help so far. :)

Finally everything is working!

It wasn't a problem with the dummy subs (they were already forced start). It seems that disabling the subtitle stream with the availability flag forced this strange behavior. So I learned something new. :)
