npaw_forge_media_kit 9.6.1

NPAW Forge adapter for the media_kit Flutter player: reports typed playback lifecycle plus mpv-level QoS (bitrate, fps, dropped frames) to the Forge core.

npaw_forge_media_kit

NPAW Forge analytics adapter for the media_kit Flutter player. Reports the typed playback lifecycle and the richest Dart-level QoS available in the Flutter ecosystem to the Forge core.

Usage

import 'package:media_kit/media_kit.dart';
import 'package:npaw_forge/npaw_forge.dart';
import 'package:npaw_forge_media_kit/npaw_forge_media_kit.dart';

final forge = await NpawForge.start(
  const ForgeConfig(accountCode: 'yourAccount', appName: 'yourApp'),
);
final player = Player();
final attachment = await attachMediaKitPlayer(
  forge,
  player,
  metadata: const ContentMetadata(title: 'Big Buck Bunny'),
);
await player.open(Media('https://example.com/stream.m3u8'));
// when playback ends for good:
await attachment.dispose();

QoS scope

Fact	Native (libmpv)	Web backend
Playhead, duration, live flag, playrate	yes	yes
Rendition (display WxH)	yes	yes
Bitrate (video track + audio)	yes	track-dependent
Video/audio codec, language	yes	track-dependent
Frames per second	yes	track-dependent
Dropped frames (frame-drop-count + decoder)	yes	no (null)
Throughput (cache-speed)	yes	no (null)
Engine version (mpv-version)	yes	no (null)

Engine facts come from a polled mpv property probe (2 s period). Polling is used instead of observeProperty because media_kit allows a single observer per property and throws on collisions with its internal observers.

Errors before the first join are reported fatal (startup failure); errors after join are non-fatal and deduplicated by message.
