有没有办法用 Quartz Composer 播放 MP3 或 aac .pls 文件？
我想在 Quartz Composer 中播放广播流。这将是开发一种新型广播播放器的第一步，该播放器具有（我希望）有趣的视觉效果来伴随音频。
给定这样的 URL：
http://provisioning.streamtheworld.com/pls/KKCM.pls
我希望作品能够播放音频。
Quicktime Player 将流式传输该电台，因此我希望有一种方法可以让 Quartz Composer 来完成此操作，但我一直无法弄清楚。
更新：我自己的研究仍在继续，我认为如果不使用 Objective-C 编写新的 Quartz Composer 插件，就没有办法做到这一点。我发现最有前途的质量控制补丁是电影导入器，但我无法使其工作。如果有人知道现有插件，请加入。
I would like to play a radio stream in Quartz Composer. This would be the first step in developing a new kind of radio player with (i hope) interesting visuals to accompany the audio.
Given a URL like this:
http://provisioning.streamtheworld.com/pls/KKCM.pls
I would like the composition to play the audio.
Quicktime Player will stream the station, so I'm hopeful there is a way to get Quartz Composer to do it, but I've been unable to figure it out.
update: My own research has continued and I don't think there is a way to do this without writing a new Quartz Composer plug-in in objective-c. The most promising QC patch I found was the movie importer, but I could not make that work. If anyone knows of an existing plug-in, please chime in.

没有内置的方法来检索任意网络数据 - 内置的，您只能检索图像（
Image Importer补丁）和 XML（XML Importer补丁）。尝试一下 http://kineme.net/product/NetworkTools — 它的
HTTP 查询 补丁将让您下载.pls文件；然后（因为它是一种非常简单的格式）您可以使用内置String补丁或内置JavaScript补丁来解析它。There's no built-in way to retrieve arbitrary network data — built-in, you can only retrieve images (
Image Importerpatch) and XML (XML Importerpatch).Give http://kineme.net/product/NetworkTools a try — its
HTTP Querypatch will let you download the.plsfile; then (since it's a pretty simple format) you can parse it using either the built-inStringpatches or the built-inJavaScriptpatch.
