问题
I am currently working in using the HTML5 audio player to provide a audio stream (24/7 radio stream) via the (mobile) browser. Loading in the stream and playing it works fine.
The major problem is that the HTML5 <audio> tag will keep downloading (buffering) content even when its not active. This could be a major issue for mobile users since most of them pay for data use. So far I have not been able to find a decent solutions that works cross browser to prevent this.
I tried so far:
- Unload the source when pause is pressed. < This does not work cross browser
- Remove the audio player element and load a new one. This works but lets be honest, this is a very hacky way of performing an extremely simple task.
I was simply wondering if there is something I'm overlooking in this whole issue since I am convinced I'm not the only one with this issue.
回答1:
The <audio> element includes a preload attribute. This can be set to "none" or "metadata" which should prevent the audio preloading.

I found a workable solution for the problem described above. A detail description can be found here: https://stackoverflow.com/a/13302599/1580615

You can do the following to stop buffering load without errors:
var blob = new Blob([], {type: "audio/mp3"});
var url = URL.createObjectURL(blob);
audio.src = _url;
or, shortened up:
audio.src = URL.createObjectURL(new Blob([], {type:"audio/mp3"});
Now you're not loading a "" which is a bad url for the audio tag to try and load. You're instead loading an actual url made from a Blob that just contains no data for the audio to playback.
