[gdal-dev] Which ONE image in a .vrt is currently being displayed?

[Even Rouault]

You can't. Because of the meaning of the 'A' in GDAL, a VRT is seen as a 
single raster for any user of GDAL API. A dedicated function should be 
created in QGIS to parse the VRT XML and make sense of it for what you wish.
