"No next track ready yet" after three track in a show
  • I've a strange problem with Airtime.
    When I put more than 3 tracks in a show, liquidsoap plays only the first 3 track. This is affected part in the liquidsoap log.
    [cross_5473:3] No next track ready yet.
    [dummy(dot)2:3] Source failed (no more tracks) stopping output...
    [dummy(dot)3:3] Source failed (no more tracks) stopping output...
    In fact is scheduled more track and in the web interface seems everything ok (except that alsa don't play any sound).
    I've hacked my lq_script adding a alsa_input when nothing is scheduled.
    I've also modify permission in tmp folder, maybe the problem is there.
    actually the /var/tmp/airtime/pypo/scheduler has permission:
    drwxr-xr-x 2 root root 4096 nov  4 09:33 scheduler
    and the file in the scheduler folder are
    -r--r--r-- 1 root root 116676515 nov  4 09:33 1122.mp3
    -r--r--r-- 1 root root   4166706 nov  4 09:33 1310.mp3
    -r--r--r-- 1 root root   3009594 nov  4 09:33 1338.mp3
    as you can see, only three.

    try airtime-check-system but yesterday my static IP address was changed
    so appears only AIRTIME_STATUS_URL with the old DNS (probably I have to
    open a new discussion for this). But the topic problem happens before

    Thanks a lot!

    and airtime-check-system
  • This is my airtime-check-system. I've solve the problem (just to set new IP address).
    What log do you need? Cause is one week that I have no show with more than 3 songs so there is no problem
  • I mean, I've solve the problem that you can see in airtime-check-system but I still have the main problem (no next track ready yet) on my airtime installation

    into /var/log/airtime
  • my var/log/airtime folder contains this file
    installation-errors.log  pypo          zendphp.log
    media-monitor         pypo-liquidsoap  zendphp.log.1.gz

  • this is the playout file when I've made some test four days ago...
  • You will have to send your  alsa input hack  or  some more information.

    but I have said this a lot of times to person wishing to use alsa input that you will encounter a number of problem if you try to use both. read this


    and this


    Use either the outputs or the inputs but not both

    There are a number of things people have done and seems to get both to work like

    • Use Alsa only on your system
    • Do not fill in the first stream tab of the stream input
    • Use a stream client rather than line input

    The key to remember is that liquidsoap is not develop based on realtime priority but on buffers and clocks.

    If you are using both the inputs and outputs then make sure your script do not have conflicts with clocks that concerns crossfades ,fallback and rotations.

    you will want to read this


    Here is a solution



    Here is some references
