GetSetMediaItemInfo()

void * GetSetMediaItemInfo(MediaItem *item, const char *parmname, void *setNewValue)

get (or set) different media item parameters:

• "P_TRACK" : MediaTrack * (read only)
• "B_MUTE" : bool * to "muted" state
• "B_LOOPSRC" : bool * to "loop source"
• "B_ALLTAKESPLAY" : bool * to "all takes play"
• "B_UISEL" : bool * to "ui selected"
• "C_BEATATTACHMODE" : char * to one char of "beat attached mode", -1=def, 0=time, 1=allbeats, 2=beatsposonly
• "C_LOCK" : char * to one char of "lock flags" (&1 is locked, currently)
• "D_VOL" : double * of item volume (volume bar)
• "D_POSITION" : double * of item position (seconds)
• "D_LENGTH" : double * of item length (seconds)
• "D_SNAPOFFSET" : double * of item snap offset (seconds)
• "D_FADEINLEN" : double * of item fade in length (manual, seconds)
• "D_FADEOUTLEN" : double * of item fade out length (manual, seconds)
• "D_FADEINLEN_AUTO" : double * of item autofade in length (seconds, -1 for "no autofade set")
• "D_FADEOUTLEN_AUTO" : double * of item autofade out length (seconds, -1 for "no autofade set")
• "C_FADEINSHAPE" : int * to fadein shape, 0=linear, ...
• "C_FADEOUTSHAPE" : int * to fadeout shape
• "I_GROUPID" : int * to group ID (0 = no group)
• "I_LASTY" : int * to last y position in track (readonly)
• "I_LASTH" : int * to last height in track (readonly)
• "I_CUSTOMCOLOR" : int * : custom color, windows standard color order (i.e. RGB(r,g,b)|0x100000). if you do not |0x100000, then it will not be used (though will store the color anyway)
• "I_CURTAKE" : int * to active take
• "F_FREEMODE_Y" : float * to free mode y position (0..1)
• "F_FREEMODE_H" : float * to free mode height (0..1)

Parameters

MediaItem *item,
const char *parmname,
void *setNewValue

Returns

void *

		MediaItem *NewItem=AddMediaItemToTrack(TheTracks[0]);
		MediaItem_Take *NewTake=AddTakeToMediaItem(NewItem);
		double TimeSelStart=0.0;

		GetSetMediaItemTakeInfo(NewTake,"P_SOURCE",NewPCM);
		GetSetMediaItemTakeInfo(NewTake,"D_STARTOFFS",&MediaOffset);
 
		GetSetMediaItemInfo(NewItem,"D_POSITION",&ItemPos);		GetSetMediaItemInfo(NewItem,"D_LENGTH",&ItemLen);		Main_OnCommand(40047,0); // build any missing peaks
		SetEditCurPos(ItemPos+ItemLen,false,false);
