Re: [android-developers] Re: HLS audio and getDuration / seekTo strangeness

Because downloading a 12 hour audiobook is not exactly a good user experience.

Hls allows them to have the experience of having it locally without the massive download.

Why are you using HTTP Live Streaming for pre-recorded audio?

This doesn't sound like the best tool for the job.

Thanks.

Yes, I call prepareAsync after I register a OnPreparedListenter - this
is happening after that gets triggered (as a test, in the onPrepared
method, I log the duration: It's zero there, too).

What's really strange to me (here's a snippet) is that it takes a few
seconds to determine the duration.

---
mediaPlayer.start();
mediaPlayer.pause();
Log.d(TAG, "waiting 10 seconds for duration to be known...");
long waitForIt = System.currentTimeMillis() + 10000;
while (System.currentTimeMillis() < waitForIt) {
  if (mediaPlayer.getDuration() > 0) break;
}
Log.d(TAG, "now:       " + System.currentTimeMillis());
Log.d(TAG, "waitForIt: " + waitForIt);
Log.d(TAG, "duration:  " + mediaPlayer.getDuration());

Log.d(TAG, "seeking to: " + milliseconds);
Log.d(TAG, "playing:    " + mediaPlayer.isPlaying());
mediaPlayer.seekTo(milliseconds);

This hideous mess takes anywhere from 2-6 seconds to break out of the
while loop. Once it does, I get a duration and can call seekTo().

Also, even though the start() and pause() calls are executed that
close together, they still cause the player to play 1-2 seconds of
audio.

Without those calls, the full 10 seconds elapse and I *still* don't
get a duration and seekTo doesn't work. :-/
