Yes, there is a libdv function to compute the number of samples per
frame along a "locked audio" sequence: dv_get_num_samples(). The reason
dubdv (and all utilities in encodedv) do not use this and the encoder
interface of the library is due to historical reasons. These utilities
are not necssaruly the best tools and rarely maintaiined, but remain for
historical value and to honor the developer who originally contributed
them as well as the libdv encoder.
