seek does not work on ios 13.5 for live audio streaming #1379

Open anleodev opened 4 years ago

anleodev commented 4 years ago

When I run a stream on ios and want to rewind back it does not rewind anything though the method works

this.activeStation.player = new Howl({ src: 'http://online.kissfm.ua/KissFM', html5: true, preload: 'metadata', }); await this.activeStation.player.pause(); await this.activeStation.player.seek(30); await this.activeStation.player.play();

I got a similar issue. Does it work if you set html5 property to false?

Assuming that you are not trying to seek into the future (your code example could be read that way), instead doing something like: play → pause for 30s → seek forward 30s
...i still see almost no chance to do this reliably.

What I have found dealing with similar problems is that HTML5 audio seemingly wasn't built with a focus on live streams, plus every browser adds idiosyncrasies on top. E.g. there is no way to specify buffers - usually these are more important as pre-buffers. What you are looking for is a kind of post-buffer, which assumes that the browser keeps any amount of media stored & accessible. (On a related note: there is no way to specify how long you can reliably pause a live stream...) Even if rewinding a stream works in other browsers/OSs I would not count on it. For live streams I would consider this behavior undefined.

(Oh and, conceptually: live streams, especially radio, usually weren't meant to be paused. AFAIK this is more in the domain of TiVo/DVR/PVR...)

@jchristin -- live streams only work with html5=true IIRC.
