[FFmpeg-devel] [PATCH 0/3] Direct Stream Digital (DSD) decoder and demuxers

[Peter Ross]

based on dsd2pcm: https://code.google.com/p/dsd2pcm/

samples: http://www.2l.no/hires/

the DSDIFF format is 64-bit IFF. I have added this to the current IFF demuxer
(that uses 32-bit chunk sizes). Does this make sense?

dsd2pcm is flaot based, and uses doubles in the intermediate summation.

  DSD Stream File (DSF) demuxer
