Hmmm, 'yuvscaler' has never (that I recall) performed chroma resamping.
Perhaps you meant 'y4mscaler' ;)

For reasons known only by the author permission to integrate
'y4mscaler' into mjpegtools has been not been granted.
Second, yuvscaler does not understand the above syntax.
Quite so - wrong program :)

If you're using the cvs version of mjpegtools you'll want y4mscaler 8.1
kit. It's necessary to edit the Makefile to set the compiler options
and manually 'mv' the executable and manpage where you want them.
