Hello,
I am working on a project related to an open source dance game (StepMania).=
I have some licensed music, and one of the requirements is that the files=
not be distributed in an easy-to-access manner (basically, DRM).
I'm considering using Matroska as a basis for this project, and was wonderi=
ng if anyone had comments on the idea or suggestions for the best way to do=
the integration with the specification.
The data I'm trying to represent is relatively simple. In-game songs are p=
ackaged into a folder containing the audio, a background video, and the ste=
p chart (metadata). These are put into parent folders to organize. They l=
ook something like this:
Pack_A/
Song_A/
Song_A.aac
Song_A.mp4
Song_A.sm
Song_B/
Song_B.aac
Song_B.mp4
Song_B.sm
Pack_B/
Song_A/
...
I'm considering having each "Song" be it's own Track, and the packs each th=
eir own segment. The step data would be attached to the track. A control =
track would be used to contain the rest of the information for licensing (E=
ncryption Metadata). ContentEncodings would be used to provide decryption =
information for the tracks themselves.
If there was a way to make any of what I'm working on useful to the Matrosk=
a team, I'd be glad to contribute code.
