To quote the first few lines of the output:

  D..... = Decoding supported
  .E.... = Encoding supported
  ..V... = Video codec
  ..A... = Audio codec
  ..S... = Subtitle codec
  ...S.. = Supports draw_horiz_band
  ....D. = Supports direct rendering method 1
  .....T = Supports weird frame truncation

So that line of your output I quote indicates that FFMPEG can
*decode* Bluray PCM, but it can't *encode* it, which is what you
want.  If you figure out how and want to submit a patch to do it,
as Carl said, you are very welcome!
