Error gap-filling Landsat 7 SLC-off with QGIS 2.18.3 on Windows 10

Question

I am trying to gap-fill Landsat 7 SLC-off images with open-source software as explained in the comment below this post.

I'm new to QGIS and have almost no knowledge with Python (I'm a GIS novice normally working with ArcGIS 10/Pro).

GdalTools is installed and checked and I am using the Band 1 mask (from USGS download) on Band 1. When I run FillNoData, it returns Band 1 with the gaps remaining.

Ok, I've gotten it to work! Executing from commandline seems to be irrelevant, temp file seems to have been irrelevant.

What did work is I changed pixel search distance to 10 (just for the test), and then unchecked "band to operate on" and "do not use default validity mask". Only loaded 1 band at a time into QGIS. Now I'll tweak from here.

It may not matter but it appears you're output file is going straight into a tarball. You could try outputting (and reading from) elsewhere.

You could also try executing the the gdal_fillnodata command directly in GDAL commandline/shell (e.g. copy and paste the command from QGIS window, start the OSGEO4W shell, paste and execute).
