Hi Herbie,

> Does that mean it is impossible to use "libffmpeg.dylib" with ImageJ 1.x?

Unlikely "impossible", but I do not know how difficult it would be, and I
do not have time to experiment right now. Wayne probably has a better idea.

> Where does "FFMPEG_IO.jar" (which works) expect "libffmpeg.dylib" on a
Mac?

Check the java.library.path system property.

Curtis
