I used this docker image successfully on a SID file and it claims support for ECW format also: https://hub.docker.com/r/klokantech/gdal/ And then, as Richard Duivenvoorde suggested, convert your ECW to a geotiff. A geotiff with YCbCr JPEG compression and overviews can be nearly as small as a SID or ECW and in my experience is better performing.
