So I've been asking for certain plugins that would help improve creativity in VDJ for quite a while and thought well I do have some knowledge of C++ however limited so I thought I would undertake it.
This is basically the scratch plugin with a revision it is going to apply alpha when the timecode speed goes below 50% that gradually fades to zero
Now the code for allot of part is boll*cks as I'm not a seasoned C++ programmer and I am goin to some help getting this cookie going
First of all though I need to know whether I can calculate speed from angulation to do this if say CEL could give me a little more info on how it works please!!!
Here is the code so far
#include <windows.h>

Hello mate...
Good on you for giving it a go, you've started out with the hardest type of plugin too!! I can't yet advise on the timecode side of things I'm afraid - I've not done any development there. I've done a few video plugins now though :)
Looking through your code, I'm not sure where you've got your samples from or what version of SDK you are using? For example, I'm not sure where you've got those other public class functions from...
HRESULT __stdcall OnProvidedInterfaceInit(TProvidedInterfaceInit *Init);
HRESULT __stdcall OnCalculateOpacityInit(TCalculateOpacityInit *Init); // Calls for final Opacity calculations
HRESULT __stdcall OnRenderOrderInit(TRenderOrderInit *Init); // Calls for Render Order
HRESULT __stdcall OnRenderInit(TRenderInit *Init); // Calls for render
For a video transition, the rendering is done in:
HRESULT __stdcall Compose(int crossfader,HRESULT(__stdcall *RenderSurface[2])(),TVertex *vertices[2]);
...and those functions you listed about aren't anywhere in the latest SDK?
Nice idea for a plugin though, will be happy to hook my TC up and help you out where needed.
One question though - as you are going to Alpha based on speed, is this plugin designed to show one video, fade it out to black by killing one deck effectively revealing the other video underneath?
Regards,
Scott

Thats exactly what I'm trying to do... (these conditions)
The slower the deck goes the alpha channel drops revealing the layer underneath or other video
Exceptions when the videofader is either extreme left-right when just one channel is rendered.
It also means that if just one deck stopped either slowly or abrutly the channel will fade to black corrispondingly which i think would be advantagous in terms of the music being fused with audio.
It also means when your scratching and doing flare or tear type scrathes (anything that has a fake click), the click would regiester and visually react in time (one clicker flares still look horrible becasue of the syncapation used)
My end goal is to tie in a GetInfo() for video fx param (say 5 & 6) which can be controlled by midi and then VDJ has an Answer to V-SL's fade to black on the channel fader... (I think this could be very benifical to VDJ) Also because of the render order it could be useful for plain mixing i.e. The channel thats playing is the back layer because the crossfaders has been over that side last and the channel that you are bringing in would fadeout the underlying video... Hey Presto... You've got a video trainsition with upfaders. No extra video fading need (you can't say thats not worth somthing).
I apreciate any advice on this I havn't touched C++ in along time. I hav'nt even got the header files in the right place (using VS2008) any help just getting it working would be help (I have installed windows SDK and DX SDK) + what setting in VS2008 should I be using for a DLL... Hence why I was asking on a previous thread.
Some of the code I worte I tested in little console apps to make sure I got facts right and the code is skelital structure of the plugin. Kinda rough guide (I basically know how the plugin should work but I'm getting caught up in syntax and code) But I know the variable manipulation is sound.
So can anyone help with estimationg time code speed per deck and representing it as say a percentage... (thats one problem)
Anyone help to properly compile DLL's (thats my second)
Also if I asign a variable at the start of the code in private and give it a value does that code get reinitialised and the value reset if so do I do it in the onload section....
Cheers for help scott... Ignore the public class boll*cks I think I made half of them up to get my chain of thought right.

Apparently it was an UNICODE problem (change it in your project or adapt your C++ code)

Cheers guys,
I actually getting stuff working now so onwards and upwards
CEL
if you could tell me exactly what Angle() relates to... dont want to have to do a timer and position record to calc speed of deck if I dont have too!

I see what you want to do but it can't work like that: it's either a dsp plugin either a video plugin but not both at the same time.
Because you will have a problem in DllGetClassObject() for *ppObject=new MyPlugin();

Do you intend to use the old SDK of VirtualDJ?
If you use the new one, you have to write:
HRESULT __stdcall MyPlugin::OnGetPluginInfo(TVdjPluginInfo *infos)
{
infos->Author="iKutZ";
infos->PluginName="Ultimate Transition";
infos->Flag=0;
return S_OK;
}
