Demo not working

Hi thought you might like to know that the demo doesn't appear to be working. I'm on Chrome 62.

on iphone this doesn't work...

I was trying to replicate this behaviour and i succeed in getting it work on Android and pc, but on iphone when it swich the source buffer the sound just stops playing... no error no console warning... probable it wait an explicit user click of every sourcebuffer ?
Any idea on how to solve this ?

Live stream

Is it possible to modify the code to support a live stream instead of a file?
In a live stream, we won't need to keep buffers after they were played and decode everything on each incoming frame.

I tried to decode and play each buffer separately with a new audioSource instead of appending everything to a single buffer but I have timing issues. Sometimes new chunks are cut or plays too fast.

Can you please explain the following?

• Why there are single digit milliseconds overlaps and how scheduledTime helps?
• Why do you add 0.010 to current time and decrease 0.05 from start time?

Not an issue just a thank

Thanks for publishing this. Going to try to use it with a socket.io stream instead of an XHR
