FFmpegAudioDecoder 是否应该在附加新的初始化段时重新初始化

问：

我正在尝试切换音轨，但在切换时，FFmpegAudioDecoder 永远不会像处理不同分辨率的视频轨道那样重新初始化。我不确定这是否是 FFmpegAudioDecoder 的预期行为，并希望了解有关预期行为的更多信息。

切换音轨时，我最终会调用以下操作：

if sourceBuffer.getIsUpdate() {sourceBuffer.abort()}
sourceBuffer.remove(0-videoDuration)
initSegmentDataStream = fetch init segment of new audio representation
sourceBuffer.appendBuffer(initSegmentDataStream)

这些是初始视频加载中的“媒体”选项卡消息

相比之下，这是我在附加不同视频分辨率/轨道的初始化段时得到的

video decoder config changed midstream, new config: codec: av1, profile: av1 profile main, level: not available, alpha_mode: is_opaque, coded size: [1920,1080], visible rect: [0,0,1920,1080], natural size: [1920,1080], has extra data: false, encryption scheme: Unencrypted, rotation: 0°, flipped: 0, color space: {primaries:BT709, transfer:BT709, matrix:BT709, range:LIMITED}

在附加音频轨道的新 init 段时，我希望 FFmpegAudioDecoder 能够像 Dav1dVideoDecoder 对视频轨道所做的那样重新初始化
