[emms-help] No mpv support for now

[Yoni Rabkin]

Today I had a look at adding mpv as a player to Emms.

According to the mpv developers, the right way to use mpv would be via
it's IPC communication mechanism using JSON. However, the version of mpv
which comes on my system is too old (0.3.4), the version with the stable
command-line option to do the communication (--input-ipc-server) was
introduced in 0.17.0, and on my system I can't even compile that version
since my libavcodec is too old.

In other words, I can't add mpv support at this time.

Too bad.
