Queue shows 0:00: YouTubeEngine passes duration in seconds but SpotubeAudioSourceMatchObject expects microseconds

Current Behavior

Related

• Possibly same UI symptom as Media Duration #782 (0:00 in queue), but this report is a different root cause (audio-source match JSON units, not queue/track JSON persistence).

Summary

Plugin audio source receives duration from MetadataPlugin.create() → YouTubeEngine callbacks. That value is passed through Hetu plugins as SpotubeAudioSourceMatchObject JSON.
SpotubeAudioSourceMatchObject.fromJson interprets duration as microseconds (Duration(microseconds: json['duration'])).
The engine currently sets 'duration': video.duration?.inSeconds, i.e. seconds (e.g. 210 for 3:30). That becomes Duration(microseconds: 210) ≈ 0 → displayed as 0:00 in the queue when UI uses sourced match duration.

Where

lib/services/metadata/metadata.dart — inside createYoutubeEngine / YouTubeEngine callbacks:

• search map: 'duration': video.duration?.inSeconds
• getVideo map: 'duration': video.duration?.inSeconds

Suggested fix

Use microseconds to match JSON contract:

'duration': video.duration?.inMicroseconds,

### Expected Behavior

// metadata.dart — both search() and getVideo() callbacks:
'duration': video.duration?.inMicroseconds,  // ✓ microseconds
Affected: All audio source plugins using yt.search() / yt.getVideo() (YouTube Audio, NewPipe, etc.) — TrackTile duration in PlayerQueue always shows 0:00 for sourced tracks.

### Steps to reproduce

1. Install / launch Spotube (Windows is fine).
2. Set the audio source to the YouTube plugin or NewPipe (any engine backed by YouTubeEngine).
3. Sign in to metadata (e.g. Spotify plugin) and enqueue a playlist/album, or use tracks where the UI relies on sourced duration / shows missing duration.
4. Open the playback queue (queued tracks list).
5. Observe: the duration column for tracks shows 0:00 (or effectively zero), even though playback works and the matched video has a real length.

Great bug report! The root cause analysis is spot on. I traced this through the codebase and the fix is straightforward.

The SpotubeAudioSourceMatchObject.fromJson deserializes duration as microseconds:

Duration(microseconds: json['duration'])

But YouTubeEngine sets it as seconds:

'duration': video.duration?.inSeconds  // ❌ wrong unit

The one-line fix:

'duration': video.duration?.inMicroseconds  // ✅ correct unit

This should be applied in both the search() and getVideo() callbacks inside lib/services/metadata/metadata.dart to be consistent.

Also worth checking: if video.duration is null for a live stream or an age-restricted video, inMicroseconds will throw since it's called on a nullable. A null-safe version:

'duration': video.duration?.inMicroseconds ?? 0,

Happy to raise a PR for this if the maintainer confirms the fix direction! 🚀
