Background service to add support for variable speed or pitch for playback of MP3 and Ogg Vorbis files. AAC is not supported due to existing patents.

If you sent me an e-mail from Google Checkout, e-mail responses are bouncing as undeliverable. Please e-mail me directly at aocate@gmail.com

I have been informed that the following apps have added support for Presto:
- BeyondPod
- DoggCatcher
- PodTrapper
- Pocket Casts

The Presto developer is a different developer from those applications. Those developers are not responsible for Presto's implementation, bugs, or cost.

Presto is still in beta. Bugs are listed at the end of this description. Please e-mail me if you find new bugs. I apologize for the lack of updates; I bit off way more than I can chew this semester. Work is ongoing, but I can only spare a few hours at a time on some Mondays. Please be patient.

Apps using Presto must be restarted after upgrading Presto.

Download problems are a problem with the Android Market, not with Presto. See these pages for potential solutions:

http://code.google.com/p/android/issues/detail?id=1996#makechanges

For developers: See the home page for nearly drop-in code that replaces android.media.MediaPlayer, using Presto when available, or gracefully degrading to use the default Android MediaPlayer when not.

Known bugs (please e-mail me if you find any new ones or any of these impact you too severely; I have no means to respond to Market comments). Asterisks (*) indicate bugs that have not been observed in a while; please e-mail me if you encounter them so I can confirm they are not fixed.

#18 - ANR In BeyondPod

Remember that sending an e-mail is a lot more likely to get a problem fixed than anything else (such as posting a comment).

Internet access is necessary to play files from the Internet; before ICS, this was inherited from the calling app, but ICS changed this.

Recently changed in this version

Adjust permissions to explicitly request those required to be explicitly requested by Nexus 7. The upshot is Presto should appear on Google Play for Nexus 7 devices. This is not a permissions creep: The only new permissions are ones that were implicitly requested before.

    Downloaded for use with beyondpod but crashes frequently; about once every 2-3 days.

    Fails to move onto the next track. BeyondPod pauses with a "!" indication. Typically nine seconds shows as remaining, even though the audio has played right to the end. This doesn't always happen, but often it does.

    Get Pocket Podcasts. It has speed control built in.

    It keeps giving me a validation error, even though I bought this months ago. I contracted the developer, but I never heard back

    Using Presto with Doggcatcher introduces unresponsive controls, fails to start podcasts, and randomly opens settings menu instead of Doggcatcher. None of these problems exist with Doggcatcher alone or with a different variable speed audio library.
