[campcaster-dev] Questions about the XML-RPC API

    Hi,

    we made some progress with our daemons for Radio Orange. The one daemon
    listens on a sound card over alsalib and if no sound is available, it
    talks to a perl daemon which switches a Matrix Switch and talks via
    XML-RPC to the Campcaster scheduler (and restores the Switch if sound is
    available again).

    I have two questions:

    1.) Scheduler/gstreamer reactivity
    I noticed, that when I schedule a playlist for now() it will be played
    by the scheduler immediately, but I do not hear any sound. If increment
    now() by 15 seconds, I hear the sound. Anything below 10 seconds will
    for sure not work in terms of hearing any sound. Is this delay
    normal/planned?

    2.) Removing currently playing playlists
    Is it possible to stop and remove a running playlist? I have used
    stopCurrentlyPlaying and it actually stops sound output. By using
    removeFromSchedule the scheduler says it can't remove it because it is
    playing. Is there a XML-RPC method for stopping and removing a currently
    playing playlist? Or is this simply not possible by design?

    Mic

    PS: Thanks for this amazing software, the new release and the great
    support on IRC.

    Hi!
    Take a look here. Some of these are known bugs.

    Hi Michael -
    Yes, this is a known bug. It only happens with playlists - they take
    about 10 seconds to load per hour of songs. The scheduler and the GUI
    interface deal with this by pre-loading the playlists 10 seconds before
    they start playing. We hope to speed this up in the 1.2 release.

    Hopefully Tomas can answer this one...

    Thank you for reporting this bug; it has been filed as
    http://code.campware.org/projects/campcaster/ticket/2095
    and it will be fixed in the next release.

    The timeframe of 10 seconds should be ok. If this will be less in the
    next release the better Smile

    This is very important for the implementation at Radio Orange. The
    running playlist should be stopable and removeable in order to upload a
    new playlist which matches the current studio audio output.

    Can anybody help me with this?

    We're going to implement this for our next release, due out at the
    beginning of January. If you would like to help us out, let us know and
    also stop by in the IRC channel: irc.freenode.net/#campcaster
