How to get pointer to a gstBuffer with QtGSTreamer

[pfarmer]

Sorry. Strange. Here again: 


Thanks

I actualy would like to have the data from the buffer. So that would be
ideal:
bufferptr->data().  

And it works. This was what I was searching for. Simple enough.

So the newBuffer() function looks like this:

    virtual QGst::FlowReturn newBuffer()
    {
		bufferPtr = pullBuffer();
		unsigned char* imageData = static_cast<unsigned char*>(bufferPtr->data());
		m_image->image.setValue(SbVec2s(resX,resY), bytesPerPixel, imageData );        
        return QGst::FlowOk;
    }



Is this good to use?

Is it garanteed that the data in the Buffer stayes untouched during the copy
process in the image.setValue() function? Or do I have to take special care?

data() function returns a pointer to quint8. So I have to assume that quint8
is the same as uchar on the machine. Is there a better way for the
conversion?
