Hi, I was able to reproduce the problem, and it is definitely timing dependent. For the eclair codebase, I found a problem in OpenCORE's mp3 parser node. That, however, has been fixed on the latest codebase available at kernel.org.
Now, for applications that are being written for existing Android SDK releases, I don't have a way out yet. -Ravi On May 12, 12:47 pm, SDS <[email protected]> wrote: > I’m experiencing an intermittent and very frustrating issue with > MediaPlayer on Android when streaming MP3 over HTTP.
