While splitting core is not directly supported (we need a new bitstream
filter), you can still achieve it with a trick, by passing the stream
through the S/PDIF IEC 61937 muxer and then demuxer, with HD disabled, e.g.:
ffmpeg -i DTS-HD_MA.dts -f spdif -dtshd_rate 0 -acodec copy - | \
ffmpeg -i - -acodec copy DTS-Core.dts
