And I get an error

Is this a coding error or I'm missing something? Please help

Thanks

Re: Qimage trouble mlt revision 1218

In the file

https://mlt.svn.sourceforge.net/svnroot ... rapper.cpp

I found this code, please check if this is correct

#ifdef USE_QT4
		// Note - the original qimage is already safe and ready for destruction
		QImage scaled = interp == 0 ? qimage->scaled( QSize( width, height)) : qimage->scaled( QSize(width, height), Qt::IgnoreAspectRatio, Qt::SmoothTransformation);
		QImage temp;
		bool hasAlpha = scaled.hasAlphaChannel();
		if (hasAlpha)
		    temp = scaled.convertToFormat(QImage::Format_ARGB32);
		else 
		    temp = scaled.convertToFormat(QImage::Format_RGB888);
#endif

I've also checked the qimage.h file on my system and it does not have any reference to RGB888 

public:
    enum InvertMode { InvertRgb, InvertRgba };
    enum Format {
        Format_Invalid,
        Format_Mono,
        Format_MonoLSB,
        Format_Indexed8,
        Format_RGB32,
        Format_ARGB32,
        Format_ARGB32_Premultiplied,
        Format_RGB16,

I modified the original file and changed the RGB888 to RGB32 and it worked all right.
