iPhone 中的直播
ALAC 格式是否支持 iPhone 中的直播？ ALAC 音频录制格式是否流式传输到服务器计算机？那么我能够播放音频块数据吗？ALAC 格式支持吗？
谢谢。
Will the ALAC format support live streaming in iPhone ? the ALAC audio recording format is streamed to Server machine? so will i be able to play the audio chunk data, does ALAC format support?
Thank You.

假设你的意思是“Apple Lossless”音频......
我不明白为什么它不会，但我不知道细节。您可能需要将其嵌入传输流而不是 MPEG 4 容器中（但是，我也不知道 HTTP 直播流是如何工作的）。
不过，我认为传输无损音频并不明智。
Assuming you mean "Apple Lossless" audio...
I don't see why it wouldn't, but I don't know the details. You'll probably need to embed it in a transport stream instead of a MPEG 4 container (but then, I don't know how the HTTP live streaming works either).
I don't think streaming lossless audio is sensible, though.
流式传输无损音频是可能的，我们使用 Icecast 进行 flac 流式传输，效果非常好。然而，我们并没有使用 HTTP Live Stream (HLS) 来做到这一点。我们将 flac 从源生成器流式传输到许多服务器，然后它们从那里创建 HLS。
从技术上讲，可以将 alac 混合到 mpegt 中（ffmpeg 可以做到这一点）并播放它（使用 ffmpeg），但没有其他客户端的格式标识符。将此功能添加到 HLS 与致电/写信 Apple 并要求他们将 ALAC 添加到此列表一样简单：

并相应更新其产品。如果您购买 Apple 产品的时间不足 90 天，或者您有 AppleCare：请致电他们。如果您受到承保，他们必须为您解决这个问题。向工程师提出的请求越多，他们就越有可能在 HLS 中添加对 alac 的支持。
Streaming lossless audio is possible, we have flac streaming using icecast and it works beautifully. However, we are not using HTTP Live Stream (HLS) to do it. We stream flac from the source generator to a number of servers and they create HLS's from there.
It is technically possible to mux alac into mpegts (ffmpeg can do this) as well as play it back (using ffmpeg), but there isn't a format identifier for other clients. Adding this feature to HLS will be as easy as calling/writing Apple and asking them to add ALAC to this list:
http://www.smpte-ra.org/mpegreg/mpegreg.html
and update their products accordingly. If you've purchased an Apple product less than 90 days ago, or you have AppleCare: give them a call. They have to work on the issue for you if you are covered. The more requests that get elevated to their engineers, the more likely they are to add support for alac in HLS.
