DV serial devices support for DSD demod

DSD demod update

DV serial devices such as the ThumbDV are now supported to decode AMBE frames. Such devices expose the serial interface of the official DVSI AMBE3000 chip. This lifts possible patent issues with mbelib as already mentioned and offers a slightly better audio. However bear in mind that it uses a serial interface at 460 kb/s which is fairly fast but not as fast as a software codec. This limits the possibility of running decodes in parallel. To circumvent this you can add as many DV serial devices to your system as you wish and all will contribute to the global throughput.

Please note that this does not work in Windows.
