Comment (by xtemp09):

 I'm sorry, of course it's a mistake; I thought that ffmpeg uses libflac. I
 meant flaCCL have better compression in comparison with libflac. Besides
 better compression, it's ~7 times faster than libflac, since both openCL
 and CUDA increases encoding considerably.

 gjdfgh, I started converting a large WAV file (of 1 hour duration) into
 FLAC last Saturday on 12-core Xeon cluster at maximum compression level.
 It's about 80% done. The thing that makes me sad is that only 100% is used
 and my kick-ass videocard is no use here. :(

 If I could write a patch, I wouldn't make the feature request; I would
 have done it by myself. :)
