Now implements streaming download+decryption entirely in Rust:
- Added reqwest/tokio/futures-util dependencies
- Created StreamingDecryptor for chunk-by-chunk decryption
- New download_and_decrypt_track command streams to disk directly
- Frontend simplified to single invoke() call
Cover art lookup was constructing paths from raw metadata without
sanitization, causing "No such file or directory" errors for artists
with special characters (e.g. "Au/Ra" looked for "Au/Ra/" but files
were saved to "Au_Ra/"). Now uses sanitizeFilename() to match the
actual on-disk folder structure created during downloads.
Playlist downloads were not fetching album cover URLs, causing both
embedded cover art and folder cover.jpg files to be skipped. Queue
manager now fetches album data on-demand (only when cover art is
enabled) to get cover URLs, reusing the same logic as individual track
downloads. Fetches track data first if albumId is missing.
("Track token has
no sufficient rights on requested media").
Previous behavior:
- Only tried format fallback (FLAC → MP3_320 → MP3_128)
- Used same track token for all format attempts
- Failed when error 2002 occurred even if alternative tracks existed
New behavior:
- When error 2002 occurs, fetches FALLBACK.SNG_ID and gets fresh token
- Retries with same format but different track ID
- Loops through all alternative track IDs before trying format fallback
- Only after exhausting alternatives does it fall back to lower quality formats
Add support for selecting a fallback audio format if the requested
track format is unavailable. Users can now choose to fall back
to MP3_320, MP3_128, or the highest available format, or opt to fail
if the requested format is not found. The queue manager and downloader
now fetch fresh track data just-in-time, handle dz fallback
parameters, and ensure the correct track ID is used for decryption.
Settings UI and store are updated to allow configuring the fallback format.
Add logic to find and use album cover art as a fallback when playlist
cover art is missing, both for local and online playlists. Update
database schema and upsert logic to store album picture URLs for
online tracks. Improve UI to display fallback cover art when needed.
