While running jb-alvarado's media-autobuild_suite, sources were updated between building 32 and 64 bit binaries, just after the 32 bit ffmpeg build finished, so the 64 bit build failed, because: "--enable-libschroedinger" is unsupported now.

>Schrödinger's codec is dead now
Came for the cat joke, but decided to be serious instead.

libschroedinger is indeed dead -- that is certain -- but it turns out libschroedinger was only one implementation of the Dirac (https://en.wikipedia.org/wiki/Dirac_(video_compression_format)) codec; vc2 (https://www.ffmpeg.org/ffmpeg-codecs.html#vc2) continues on.

Fom an old ffmpeg -codecs listing: DEV.LS dirac Dirac (decoders: dirac libschroedinger ) (encoders: vc2 libschroedinger )

And a new one: DEV.LS dirac Dirac (encoders: vc2 )

Ah, so it was mainly a naming decision, less a project getting abandoned.
