    Question VOD MP4 files with multiple audio tracks - Delivery and web playback

    We have an archive of MP4 h264 multi-track videos.

    When a user visits our site and requests to see a video through our site, we would like to send parameters such as filename or fileID and audio track ID to WOWZA.
    Then WOWZA delivers the specified file and corresponding audio track.

    Example:
    a video has 3 audio tracks: track 1 = English, track 2 = French, track 3 = Spanish
    The website visitor selects their preferred language and the player sends WOWZA the file ID and track ID to use. WOWZA then delivers the desired video and audio track.

    Is this possible?

    For Flash RTMP clients, you can override play:

    To deal with other clients also, you will need to use IMediaStreamNameAliasProvider2

    excellent

    what about selecting a single audio channel from a track?

    example: i want to play only the left audio channel from track 1

    I'm not sure if that is possible, I don't so. You can select one of many tracks:

    what would the cost be to get WOWZA to build the functionality for us either in the wowza core or as a module?
    can you provide a quote?

    I might be wrong, but I dug around the server-side API and haven't found anything. You can get a list of independent Wowza consultants by sending request to support@wowza.com.

    I confirmed: it is not possible to select one channel from a stereo audio track.

    Richard, is it possible to build a custom MediaReaderH264? The class is in wms-mediareader-h264.jar, but I don't know if it's possible to extend this class. I'd love to explore the possibility of selecting the channel within a track.

    Robert,

    Yes, take a look at the bottom of the midroll example that shows an example that extends MediaReaderH264.

    Also take a look at the IMediaReaderActionNotify interface:
