Image footprint in Landsat mosaic using GDAL

I need to produce a Landsat mosaic over part of Indonesia and an extra shape file containing the dates of each part of the mosaic.

The steps I used are:


  1. Stack 3 bands to produce RGB image
  2. Project images into WGS84 (gdalwarp)
  3. Build a virtual stack (mosaic, in this case) using gdalbuildvrt.
How can I produce polygons shapefile that contains the the footprint of each Landsat image within the mosaic (hence the date)?

Any help is highly appreciated
