* Initial playlist-based custom soundtracks support
This is the initial implementation of playlist-based (cellSearch) custom soundtracks support.
It is based on the initial work by @Megamouse and currently uses a directory-based approach to manage albums and utilizes FFMPEG to read audio metadata.
Background: The real PS3 can import music in XMB from USB into its internal storage (/dev_hdd0/music) and additionally stores metadata (artist, trackname, tracknumber, ...) in a database (/dev_hdd0/mms/db/metadata_db_hdd). Games can make use of imported music via cellSearch.
For the time being, this implementation does NOT make use of metadata_db_hdd as the db-format is not well understood and a folder-based approch is easier to use. Users only have to create folders inside /dev_hdd0/music and add music to it to create a "playlist". This playlists contents will be sorted alphabetically. As a result, users could prefix numbers to the audio-files to force a specific order.
The only really supported audio format is MP3. I also added support for AAC, AC3, WMA, ATRAC3 and ATRAC3 plus, however, non of these formats were successfully tested for several reasons. AC3 and WMA are not enabled in the current FFMPEG build which makes reading codec-specific data impossible. We could enable these later if we want to. AAC actually could work but I was not able to get it working in WipeOut HD Fury. My guess is that the game does not support AAC. Finally, I could not find any ATRAC3 (or Plus) music to test with.
This implementation currently only implements parts of cellSearchStartListSearch() and cellSearchStartContentSearchInList(). There are several other functions which are still completely unimplemented and will probably be needed by other games. However, this implementation is a starting-point and is enough for WipeOut and maybe a few other games.
A video which showcases this custom soundtrack support is available here: https://www.youtube.com/watch?v=4nu1OCtONTY
Next steps:
- Utilize sortKey in cellSearchStartContentSearchInList()
- Eliminate TODOs
- Implement the missing other functions
- Test on more games - I do not own many that support custom soundtracks
