Fixing very little bug for blu ray pcm in .mts files:

The encoder was reverse engineered from binary library and from
EP0398973B1 patent (long expired).
The decoder was simply deduced from the encoder.

With there being two hwaccels that use the CUDA pix_fmt now, just
relying on the pix_fmt to identify the selected hwaccel is not enough
anymore.
So this checks if the user explicitly selected a hwaccel, and only
accepts that one.
