           Summary: [typefind/dcaparse] fix DTS frame size for 14-bits
                    packed streams
    Classification: Platform

DTS frame size is scaled by 16/14 when parsing 14-bits packed streams, but the
header raw value should be used instead. The patches should make DTS SYNC word
detection more reliable and should also allow passthrough of DTS audio CDs to
work for 14-bits packed stream. Unfortunately I don't have an SPDIF output so I
can't test.

I've verified the right frame size is extracted with DTS certication files,
I've uploaded one here:
