    SettingDescription
    Decryption KeyFor playback of encrypted streams, enter the key provided by your administrator (see
    ‘Playing
    Playing an Encrypted Zixi Stream).
    Zixi Log ModeThis integer value sets the log entry level mode for Zixi stream messages. Available Options
    are
    : Disabled (-1)
    ,
    Debug (0 or 1)
    ,
    Info (2)
    ,
    Warning (3)
    ,
    Error (4)
    and
    Fatal (5). Note: Set only as disable unless debugging. Additional disk writes can
    effect
    affect memory and performance.
    Max Latency [ms]The maximum latency in milliseconds of the Zixi stream over your local connection between the source Zixi Broadcaster and the VLC player.  Increasing latency will add additional buffer space to compensate for network burst loss.
    Player
    Cache
    Caching [ms]The length, in milliseconds, of the VLC player cache. Using skip controls may cause the player to re-buffer
    Automatically Detect Open Ports

    The VLC Plugin will auto-detect default or common open ports at the Zixi Broadcaster

    Non-default source ports can be specified explicitly in the playback URL (supplied by you administrator)
    .
    Drop Frames
    With
    with Missing DataIn the case of data loss, when this
    potion
    option is turned on, any partial frames are removed by the Zixi Plug-In prior to forwarding to the player. This option can improve VLC stability.
    Fixed Latency‘On’ is recommended. Uses Max Latency specified when off, dynamically increases to Max Latency when on.
    Allow Latency to Decrease‘Off’ is recommended. Can dynamically lower latency when ‘On’ but may re-buffer if an increase is needed.
    Fixed end-to-end delayWhen selected, this setting guarantees synchronization of all players having the same latency settings, regardless of their location. The latency settings sets the duration of the buffer size. This means that when enabling fixed end-to-end delay, the buffer will be slightly shorter, taking into account the propagation delay from the source, because the latency is from source to destination, instead of a local delay at the destination
    FEC Overhead [%] and FEC Blocksize [ms]Do *not* alter. FEC settings are set automatically. These entries will be removed in future versions.


  6. Once you have updated the preferences, click Save and close the VLC player. Restart VLC for your changes to take effect.
