Sorry, again I am lack of studying. I just find out libschroedinger at http://evermeet.cx/ffmpeg/ Do you mean current ffmpeg does not need libschroedinger? > >> When I configure ffmpeg with the following command: >> >> $ ./configure --prefix=${TARGET} --pkg-config-flags=--static >> --disable-ffserver --enable-gpl --enable-version3 >> --enable-nonfree --enable-libschroedinger > > (note that --enable-nonfree only has unwanted effects in this > configure line.)
