[android-developers] Re: MediaPlayer seek on startup
I can't think of any alternative solution at this time. The code that handles this is in the OpenCore engine and not something you can address with a Java API. Perhaps this is something we can address in a future release. On Nov 28, 1:22 pm, David Given [EMAIL PROTECTED] wrote: David Given wrote: I'm trying to play streaming music.

Dave Sparks wrote: You must always call prepare() before seekTo(). The player engine needs to read the first part of the stream to identify the stream type and required codecs and read the content index (if it exists). Well, yes, I'm aware of that. However, it doesn't just read the stream header, it spends 10-15 seconds buffering the initial stream. This is leading to a really poor user experience, as the user has to wait (and pay) for the first part of the stream to be buffered --- then the seek happens, it all gets thrown away, and the user has to wait (and pay) for *another* 10-15 seconds while the buffer gets filled from the correct location. Is there any way of streamlining this? Can I tell MediaPlayer to *just* read the metadata and not to try and fill the buffer, for example? -- David Given [EMAIL PROTECTED] --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

What I'm finding is that if I do: mediaplayer.setDataSource(...); mediaplayer.prepare(); mediaplayer.seekTo(...); ...then the seek happens *after* the initial buffer is read, which of course is a waste [*]. But if I do: mediaplayer.setDataSource(...); mediaplayer.seekTo(...); mediaplayer.prepare(); ...then of course I get an IllegalStateException because the MediaPlayer hasn't been prepared yet! Has anyone managed to make anything like this work? [*] Actually, of course, I'm using prepareAsync(). In fact, what I'm observing is that calling seekTo() from the onPrepared() callback tends to confuse MediaPlayer and it hands me a -38 error and I have to reset and start again. It seems to only want to seek after the playback has had a chance to settle for a few moments. -- ┌─── ｄｇ＠ｃｏｗｌａｒｋ．ｃｏｍ ─http://www.cowlark.com─ │ │ ⍎'⎕',∊N⍴⊂S←'←⎕←(3=T)⋎M⋏2=T←⊃+/(V⌽⊂M),(V⊝M),(V,⌽V)⌽(V,V←1⎺1)⊝⊂M)' │ --- Conway's Game Of Life, in one line of APL signature.asc 1KViewDownload --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.
