I tested my code with 3gpp audio files, but didn't work. We decided to download and preprocess all the media resources in the meeting on June 27.

Two major issues are: hyperlinkable online storage for the media files and streamlining (automated processing).

The team decided to use Dropbox as the media storage for two reasons: REST API and hyperlink reference support. Also, the media file should be converted into web-friendly format, such as mp3 or ogg, during the existing data streamline.

I put off this task until apiprocess branch is merged.
