api - 有没有办法通过SoundCloud javascript流API强制使用MP3 block ？

Question

据我所知，SoundCloud现在以10秒的MP3块发送“流” ...然后将整个内容作为单个MP3文件加入，以某种方式在浏览器端播放。

他们还使用带有时间限制链接的Amazon Meastro Player。两者结合起来，可以防止音频被盗(主要是“另存为”问题)。

但是，当使用javascript流API(SC.stream)时，它会退回到旧方法(将整个文件下载为“正常”而非块)。有办法强制采用这种新方法吗？

并且，在这里，是否有一种方法可以强制使用Opus Codec文件？

Answer 1

当您说“MP3块”时，我假设您指的是HLS。该API将返回HLS mp3和Opus URL。

请求:
HTTP GET: https://api.soundcloud.com/tracks/90787841/streams&client_id{CLIENT_ID}

JS API中未提供此功能，您将需要使用HTTP REST API并将这些URL加载到其他播放器中。
