@@ -69,6 +73,32 @@ HLS matching preserves the old case-insensitive `.m3u8` suffix/query/hash rule.
|
||||
One explicit InputOptions assertion leaves unsupported values to SDK validation, preserving
|
||||
the old error owner rather than silently converting arbitrary inputs.
|
||||
|
||||
## Playback and readiness ownership
|
||||
|
||||
Playback intent is separate from the temporary paused state during seek. Explicit pause
|
||||
cancels pending play and prevents automatic resume; a newer seek settles the old operation
|
||||
without allowing its completion or rejection to overwrite current state. Pending play waits
|
||||
for the seek completion signal, resolved before optional resume to avoid a cycle.
|
||||
A pending AudioContext resume is shared across play-pause-play; only the current operation
|
||||
starts video and emits play/playing. Source change and destroy invalidate both operations.
|
||||
Cancellation settles the public operation while observing the underlying late result;
|
||||
actual late decoder work still belongs to MB-05/06.
|
||||
|
||||
Normal play, pause, seek/resume and HLS replacement event order is retained. Before each
|
||||
event the coordinator rechecks ownership, since a listener may synchronously pause, seek,
|
||||
load another source or destroy. Active play errors reject their Promise and restore paused
|
||||
state; active seek errors additionally publish one media error. The synchronous currentTime
|
||||
setter observes its otherwise unreturnable rejection; direct engine.seek still rejects.
|
||||
Active replacement errors remain visible even after the media object changes. Stale HLS query
|
||||
errors are ignored only when their captured source no longer owns the result.
|
||||
|
||||
Metadata publishes once after both audio/video participants report; repeated or obsolete
|
||||
callbacks cannot ready the current source. A parsed container with neither track fails with
|
||||
code 4 and message `Input has no audio or video tracks.` before decoder/AudioContext setup.
|
||||
This corrects the old false-ready state; normal valid input event order is preserved.
|
||||
Existing-track unsupported-codec handling remains a decoder capability task, not evidence
|
||||
that every capability failure has been fixed.

# PKG-MB-04：VideoShim、事件与主协调器
|
||||
|
||||
任务通过完整CI后标记done，并立即以专用本地提交交付。前置shim检查点为9af253a5；本轮将
|
||||
MediaBunnyEngine.js实际迁移为严格TS，删除其临时声明桥。包内现在16个生产TS模块，
|
||||
AudioEngine/VideoEngine两个显式临时声明桥不计作实现迁移，分别留给MB-06/05。
|
||||
文件职责、状态归属、错误传播和继续维护入口见包内ARCHITECTURE.md。
|
||||
|
||||
## 行为修复与兼容性
|
||||
|
||||
- playback.ts独立管理播放意图和操作完成信号；pause能够阻止pending play或seek恢复，
|
||||
新操作使旧结果失效。取消可先结束公开Promise，底层晚结果仍被观察。
|
||||
- seek完成信号先于可选恢复播放，避免play等待seek而seek又等待play的死锁。
|
||||
play-pause-play共享尚未结束的audio resume，只有当前操作启动video和发送play/playing。
|
||||
- 每次就绪/播放事件前重新检查归属，允许用户在回调中同步切源、销毁或改变播放状态。
|
||||
正常play/pause、seek/resume和HLS replacement事件顺序由对照测试保持。
|
||||
- 两个metadata参与者均完成才发布一次metadata；无轨道容器提前报code 4，信息为
|
||||
`Input has no audio or video tracks.`，不再错误地readyState 4。有效媒体行为保持。
|
||||
- 活动play失败保留原始Promise拒绝并恢复paused；活动seek失败报告一次error并拒绝。
|
||||
currentTime同步setter观察无法返回的拒绝，直接调用engine.seek仍能捕获错误。
|
||||
- HLS旧source查询失败不污染新source，当前查询失败继续拒绝；replacement改变media对象
|
||||
后的活动错误也不能被误认为旧查询并吞掉。
|
||||
- destroy尽力执行所有input/audio/video释放步骤，之后保留首个异常；shim仍以finally
|
||||
清理事件和synthetic RAF。事件安静不等于底层解码器晚操作已完全停止。
|
||||
|
||||
工厂签名、公开声明、canvas描述符和同步/Promise接口保持。正常事件顺序、方法转发及
|
||||
描述符对照继续纳入验证。非正常行为差异是以上明确的竞态/错误修复，不宣称逐字节行为不变。
|
||||
旧createTimeout帮助方法保持原样，受管理的load路径不使用它；不要称所有手动调用的内部
|
||||
帮助方法也都具备自动取消。
|
||||
|
||||
## 验证
|
||||
|
||||
新增40项协调器测试，使用实际构建代理、受控异步音视频操作和实际SDK解析输入。
|
||||
同一断言对adba8a3d冻结main为8通过/32失败，候选全部通过。包专项108项通过。
|
||||
main与legacy各72项通过，其中68候选产物断言、4冻结正常事件对照。三格式构建通过。
|
||||
|
||||
初轮main产物测试有一条断言把新source合法waiting/loadstart误当作旧replacement事件。
|
||||
已缩小到旧seek/readiness结果并保留完整禁止列表，重新运行main/legacy均72通过；未修改
|
||||
生产代码来消除新来源合法事件。历史同断言仍32失败，修复回归证据没有被放宽掉。
|
||||
|
||||
浏览器报告及整个results归档后记录到mb-coordination-validation.json。39项候选检查区分
|
||||
