话题: FAO CELL - Using GetInfo Queiries

由于该帖子已年深日久，可能包含陈旧过时或描述错误的信息。

Hello wise guru of all things that look matrixy lol

So how exactly do you use the GetInfo query (in transitions). I have tried it in this way with no success...

In the private: part of the class, I have defined an integer

int CurrentPosA; // Current position of track A

And then in the render section I have tried calling a value using get info

int CurrentPosA = GetInfo("action 1",&PlayPos);

The dll builds but no success, I know my other code is OK so how do I actually use this. I know from experience that this will actually be completely different

Can you rewrite that line as I'm nearing completion of a whole set of plugins for turntablists which when I'm finished I will submit for release.

Thanks again for advice,

IK

No, it doesn't work like that. GetInfo() is: 
HRESULT (__stdcall *GetInfo)(char *query,void *result); // get infos from VirtualDJ


So it's: 
HRESULT hr;

int CurrentPosA;



hr=GetInfo("PlayPos 1",&CurrentPosA);

if(FAILED(hr)) return hr;

Also Cel,

Is there a way of using GetInfo for video_fx_param_4 and 5, didnt see that on the list but would like to use these!

Do not forget that you can use GetInfo("Status")

More complicated (maybe for the future):
You can also work with the sound too with GetInfo("VideoSound") which returns a sound buffer of 512 samplesthat you can analyse then (or using with FFT)

I'm not sure to understand the goal

I can see where your going with that. e.g. volume of the audio could control elements of the video...

I just want to be able to use a midi function other than level as that effects the sound aswell as the video. I thought video_fx_param would be good but I dont know its exact name within VDJ.

have you seen my little video demo in General Discussion?...

I just want an otherwise redundant function that I can assign midi too and a plugin can read to connect the upfaders to withought using level... If you watch the video it fades on the upfaders but the audio is processed twice.
