Description LEE 2015-12-01 05:49:10 UTC 
Hello. i'm working in audiofw.
I have a question about prebuf in pulsesink.
i set prebuf to -1 like this.

  wanted.tlength = spec->segtotal * spec->segsize;
  wanted.maxlength = -1;
  wanted.prebuf = -1; <-------------- here
  wanted.minreq = spec->segsize;

after that, pulsesink can't handle EOS message. it made it lockup.
we are using audio-clock for that. if i follow system clock, lockup wouldn't be happened but we have to use audio-clock.

i have attached callstack, it seems to wait for something.
please check this problems..
Thank you.

Do I understand you correctly that you are modifying the pulsesink/src source code and then you run into this problem, but it doesn't happen with the original unmodified code as it is upstream? If so, I would suggest you post your question on the gstreamer-devel mailing list, as this is a bug tracker and not a support forum and you will reach many more people on that list.
