Tagging: follow the Free Media Player Specification

[Seirdy]

Players such as Clementine, Yarock, XMMS2, and VLC parse/write rating tags by looking for the "Fmps Rating" tag in accordance with the XDG FMPS specification; however, clerk_rating_client uses the "Rating" tag. Using the "Fmps Rating" tag would improve compatibility with other players.

Cantata, for instance, writes MPD rating stickers to the "Fmps Rating" tag.

If I knew that specification when I did my script (here) I would have payed attention...

Do you have an idea on how to do that @Seirdy ?

[Seirdy]

@Tonus1 you'd just have to rename the tag from "Rating" to "Fmps Rating".

@Seirdy Thanks, in my todolist !

@Tonus1 Full info is in Section 2.2 of the specification. Ratings should be a float value between 0.0 and 1.0, inclusive. You can just divide the standard 0-10 ratings by 10 and write to the FMPS_RATING tag.

For instance, here's the output of of metaflac --list --block-type=VORBIS_COMMENT for one of my tracks that I rated a 9/10 in the MPD sticker database (using this alias) after using Cantata's "Write Ratings To File" feature:

METADATA block #3
  type: 4 (VORBIS_COMMENT)
  is last: false
  length: 257
  vendor string: reference libFLAC 1.2.1 20070917
