Прошу реализовать Кэш. Поясню зачем и почему. Во-первых, не всегда получается находиться в интернете, а именно это - главное условие скробблинга. Во-вторых, хотелось бы, чтобы был некий кэш треков который при отсутствии интернет-соединения использовался бы для хранения треков с последующей отправкой. Такой механизм реализован в плагине для foobar2000 - foo_audioscrobbler.dll

last.fm plugin умеет класть это в очередь-отдельный файл и дрейнит её по-возможности.

That would be great. I stay with other player actually, wanted move to Deadbeef but due to my poor internet connection I can lost some scrobbles without cache mechanism :P

Присоединяюсь. Без кэша у скробблера очень неудобно.

I started a bounty for this issue https://www.bountysource.com/issues/24188373-last-fm-store-tracks-on-disk-for-later-submission

If someone decides to work on this, because of bounty or whatever, this is the suggested design:

• A separate JSON file, stored in the configuration folder obtained via deadbeef->get_system_dir (DDB_SYS_DIR_CONFIG)
• The file should clearly identify itself with type and version, e.g. via the following fields:

"type": "ddb_lastfm_queue",
"version": "1.0",

• The tracks for submission should be stored as a list of object, where each object contains the necessary information for submission (album/artist/title/playtime/...)
• The file update must be an atomic operation, i.e. write to a temp file, then rename.
• Please use jansson for JSON parsing, as this library is already used by deadbeef.
• Please make sure that this feature can be completely disabled at compile time via #define
• Example json file:

{
    "type": "ddb_lastfm_queue",
    "version": "1.0",
    "entries": [
        { "title": "...", "album": "...", ...},
        ...
    ]
}
