Precorder - Version: Alpha 0.2.0
(23 Nov 2009)


Precorder has been developed to bridge the gap between the current revision of WebOS and a future release that will enable video recording. It is capable of recording in multiple combinations of audio and video and includes support for using the built-in LED for lumination while recording in dark areas. Video recorded with Precorder is viewable through Palms built in video application.

Operating notes

When precorder is first launched you will see the main screen. Only one button is currently functional. Tapping the 'Record Now' button will begin recording video to the /media/internal location on the pre making these videos available to be copied via USB. They will be located in the root of the USB drive when connected to your computer.

When you tap the 'Record Now' button the screen will change to notify you that Precorder is currently capturing audio and video. There is a 'Stop recording' button located on the screen. Tapping this button stops the audio/video capture and returns you to the main view.

Recent enhancements

Precorder has just been released for Alpha testing.

Known bugs

Precorder is currently in Alpha stages and as such is in a constant state of flux with new features being added and old functionality being modified. Please use this software at your own risk.

First run on any phone will cause a blank output. Simply start recording, wait a moment, and stop recording, wait a moment. After that, it should be fine. Getting the video light to work may cause 2 starts. Should be a 1-time-only process.
