    VP9 is a proprietary codec that was developed by On2Technologies in May 2003. It is also called the TrueMotion video codec. VP9 is a lossy video compression format and is often used by JavaFX, Adobe Flash and Flash Video Files.

    Dacast does NOT recommend using VP9.

    If you plan to do All Device (HTML5) live streaming it is recommended to use the H.264 video codec instead.

    If the H.264 codec isnt an option for you, Dacast also supports the x264 codec.

    It is possible to live stream with VP9, but it has known playback issues in certain digital environments. Use it at your own risk.

    What is an Encoder?

    The VP9 codec has to do with your live stream encoder.

    Encoding is a process used to convert the RAW video files captured by a camera into digital files suitable for live streaming over the internet.

    This process uses either a hardware or software encoder.

    Required Live Encoder Settings

    The following live encoder settings are required for live streaming with Dacast, regardless of your selected resolution and bitrate:

    VIDEO CODECH.264 (x264 may work)
    FRAME RATE25 or 30
    KEYFRAME INTERVAL2 secs (or 2x frame rate)
    SCANNINGProgressive
    ENCODING BITRATEConstant (CBR)
    AUDIO CODECAAC
    AUDIO BITRATE128 kbps
    AUDIO CHANNELS2 (Stereo)
    AUDIO SAMPLE RATE48 kHz (48,000 Hz)

    If you have any questions about video encoding or need help with this Dacast feature, feel free to contact us directly.
