NetStream 信息返回 0（Icecast 流）

Question

我已经四处寻找解决此问题的方法，但找不到任何关于为什么几乎所有属性都返回为 0 的信息。

我正在使用 FLV 包装从 Icecast 中提取实时音频流（自 Adob​​e 以来，15 年后） ，仍然没有解决他们的实时音频内存泄漏问题）。它工作得很好，一切都很完美。

但是，我想创建一个带宽监视器（用于我的 iPhone 端口和我的普通 Flash 播放器）...但是每当我检索 netStreamInfo 时，它都会返回 0 ！对于 dataBytesPerSecond、audioBytesPerSecond、byteCount、dataByteCount，几乎每个属性都返回 0 。我在 1 秒计时器上运行了这个。

以下是总信息输出：

currentBytesPerSecond=0 
byteCount=0 
maxBytesPerSecond=0 
audioBytesPerSecond=0 
audioByteCount=0 
videoBytesPerSecond=0 
videoByteCount=0 
dataBytesPerSecond=0
dataByteCount=0 
playbackBytesPerSecond=16296.296296296296 
droppedFrames=0 
audioBufferLength=0.072
videoBufferLength=0 
dataBufferLength=0 
audioBufferByteLength=1540 
videoBufferByteLength=0
dataBufferByteLength=0 
srtt=0 
audioLossRate=0 
videoLossRate=0 Data Bytes Per Second

该输出大约持续 5 分钟。我注意到 playBackBytesPerSecond 从未改变，并且 audioBufferByteLength 喜欢在 1540 和 23xx 之间随机切换。

有人可以帮我吗？
