The first poll has finished, with some clever chap sniping at the last second to propel the screen rotation category passed the dvd2daph category. Here are the details of what I am going to work on.

I am adding support to VLDP for OpenGL surfaces. This will not only make rotation easy, but it also means that the mpeg video does not have to be the same resolution as the computer graphics overlay. How does this benefit Freedom Fighter and Star Rider? Both of these games use some kind of video enlarger which seems to zoom in the video (without affecting the computer graphics apparently). Using the current VLDP method of YUV surfaces, this kind of zooming is impossible. But with OpenGL, this becomes very easy to do. So OpenGL surfaces will make emulating Freedom Fighter and Star Rider more possible.

I have already implemented some simple OpenGL surfaces "in software" (ie with no hardware acceleration) and while they seem to work fine, they are also extremely slow. My next stop is to optimize these surfaces to use OpenGL shaders which I hope will make them extremely fast, possibly even faster than the regular YUV overlays that are currently being used.

The downside is that the fully acceleration OpenGL shaders will probably require fairly new video cards, like a GeForce FX (aka GeForce 5 series) or better (or ATI equivalent), but I am sure that won't be a big deal to those who really need this feature

Boo!!!

I came back and looked at the current voting and it had ended

Oh well, next time. If it wasn't for those damn pesky kids <Walks away muttering>

I got this working this morning. The speed is awesome! I haven't yet tried to optimize the graphics overlay, and I think I can get an additional speed boost when I do.

It will require OpenGL v2.0 capable cards. (I have a geforce 6800 ultra, for reference)

Here's an update.
OpenGL is working, rotation is working, most of the video options are working. I still need to add blending, scanlines, and vertical stretch, and then I should be done.

Screen rotation support should now be fully functional and will be included in the next version of Daphne.

Thanks again Matt

Matt, first Thank you!

lol, second... great timing i spent months on working out an easy way to rotate DL and the day after i figured it out, you came out with the rotation feature! hahahhah, couldnt have been any funnier if it had been planned!

i tried out the version of daphne that i d/l'ed yesterday, and it rotates the screen nicely. That being said, it also shrinks the video quite a bit. i am using a 26" tv monted on its side and there are quite large black bars on either side of the screen. about 2" on either side of the video, so i have a small pictrure centered in the screen, i understand that there will be on the top and bottom but, is there any setting i should be configureing, to eleminate the space on the sides?

again. i don't want to sound like a whiner. i love the new feature and think you are doing an awesome job!

I don't see how you would be getting black bars on the sides. What is your command-line (from daphne_log.txt) ?

C:\Emulators\Daphne\daphne.exe dle2 vldp -framefile D:\emulator_files\Laserdisc\DLDVDROM\lair_dvdrom.txt -fullscreen

all i have done with the config is point it to my DL Rip

the bars on the side are 1.75" (i measured it) i'll attach a picture so you can see what i am talking about.

you know what, never mind... it seems to be my screwy computer. i installed an older version of Daphne, and well, it did the same thing already rotated and in a tiny little screen.

anyways i'll have to figure this out myself, as it seems not to be a daphne issue.

Thanks anyways.

It looks like you aren't using any of the rotation stuff I added to Daphne at all. Since your video seems to be pre-rotated, you will want to reverse the X and Y resolutions with DaphneLoader (so 640x480 becomes 480x640). I added the ability to do this in the beta build of DaphneLoader v2, which I am assuming you are using (but now am thinking maybe you aren't?). You can try it out here.

Another poster has alerted me that Daphne won't allow X resolutions of anything less than 640, so 480 won't currently work, but I plan to fix this soon. You could always try 768x1024 for now

I was actually using V2.1.21 but it is on a machine without internet access so it wasnt auto updating. Now i have re-run it on a machine with internet access and have the new 2.1.25 with the rotation feature. I am going to experiment on it and i'll let you know if i find anything important!

thanks again for all your help!

The new DL kicks A@@!

Matt, when will you migrate key mapping from .99 to 2.x?

Oops, I mean, to the newer version you're working on?

That is a voting choice. I will add key mapping when it wins a poll.

What i did was, run Daphne .997 remap the keys, then copy the resulting "dainput.ini" to the directory with the newer Daphne and volia... remapped keys.

You wouldnt really even have to add key remapping into daphne. Perhaps just a small standalone program included to generate the input INI. And if you did add key remapping it would be nice if instead of a pulldown menu, just a box to type a key would be alot nicer. That way us people with non mame standard controler could just select the box and push the joystick up for up etc...

Just my $0.02...

Thanks for the cool workaround tba!
