Sample groups for SVC/MVC about mp4ra.github.io

[podborski]

Found one more vipr. There is a sample group and an additional box defined with the same 4CC. Any reason why this can not just be inside the sample group definition? Was the idea to re-use it somewhere?

class ViewPriorityBox extends Box ('vipr') {
	for (i=0; i++) {		// To end of box
		unsigned int(6)	reserved = 0;
		unsigned int(10)	view_id;
		unsigned int(32)	content_priority_id;
	}
}

class ViewPriorityEntry() extends VisualSampleGroupEntry ('vipr')
{
	ViewPriorityBox();
}
