Use lavfi-showfiltfmts for checking the format supported by the scale filter instead. The advantage is that the scale filter may support formats which are not supported by libswscale (namely: the pal8 format). The new implementation is also a bit cleaner, because it doesn't depend on the ffmpeg output.
