OTOH, as a developer of a DTS encoder (which, sadly, still has no gstreamer
plugin), I would like to advise that you drop the libdca-based gstreamer plugin
completely and switch to ffmpeg for DTS decoding if possible, thus maybe fixing
(or, rather, hiding) this bug. Reason: all versions of libdca incorrectly
decode all DTS streams that use the "perfect-reconstruction 32-band
interpolation FIR" feature (not common on DVDs, but seen on some BluRays) due
to a table that has been incorrectly copied from the specification. The
corresponding fix in ffmpeg is
http://git.videolan.org/?p=ffmpeg.git;a=commit;h=3fc45bdcf0031be526b5c1d66a9bbd386f816841
. Besides, there were some fixes for crashers in dcaenc SVN that never made it
into any released version, and support for the XCH and XXCH extensions is only
in ffmpeg, but not in libdca.
