Description Jean-Yves Lefort 2004-04-12 17:28:55 UTC 
Compile the attached test case. If the usleep() delay is increased, the audio
output starts to drop. Similarly, "gst-launch { filesrc location=foo ! spider !
osssink } doesn't work unless the gst-launch process is kept alive by regularly
sending it some signal.

Comment 2 David Schleef 2004-04-13 22:52:06 UTC 
This works perfectly for me on Linux, even with usleep(2000000000).  This
appears more likely to be a problem with FreeBSD's threading implementation.  Or
possibly, with GLib's usage of it.

You should also try with different schedulers.  I'd be surprised if it caused a
difference, but if it does, it might point to the cause.

jylefort, ping
Comment 4 Jean-Yves Lefort 2004-07-06 14:20:22 UTC 
Pong.
Comment 5 Thomas Vander Stichele 2004-07-06 15:04:09 UTC 
funny :) could you try David's suggestions and reply ?
Comment 6 Jean-Yves Lefort 2004-07-07 10:54:30 UTC 
All the tested schedulers exhibit the same problem.
Comment 7 Christian Fredrik Kalager Schaller 2004-12-07 23:54:39 UTC 
Ok, adding myself to cc. Going to mail the freeBSD porter and ask them to try
and give some input.
Comment 8 Jean-Yves Lefort 2004-12-08 00:01:17 UTC 
I think you can close this one. It does not happen anymore on FreeBSD 5.x.
Moreover, I've found out that some other sound libraries exhibited the same problem.
Comment 9 Christian Fredrik Kalager Schaller 2004-12-08 10:21:48 UTC 
ok, thanks for the update. Closing.
