Pedro,

The default output format is GeoTIFF.  There is no autodetection of output
format based on filename extensions.  If you want to produce another output
format you need to specify it with the -of flag.  The ECW format does not
support simple creation (only CreateCopy()) and is not a selectable output
format for gdalwarp.

Best regards,
