Thanks Massimo, this is working!
What I am not able to get is the time-slider to work in the audio element.
I guess that since I am streaming the audio file, the browser has no way of
knowing the size.
Is there a way to solve this problem? Is it possible to send the size of
the audio file in the response headers? I am dealing with mp3 files mainly.
I am not sure if it is possible to know beforehand (without
reading/decoding the full mp3 file) the length of the audio track. I would
say that the mp3 format (and other audio formats) must have some metadata
at the beginning of the file specifying things like duration, volume, ...
but I am not familiar with these details.
And as a more general problem: is it possible at all to randomly access a
streaming audio file? I would say that this is not possible.
Any ideas / workarounds to get the slider working?
Thanks,
Daniel
