[maemo-developers] [maemo-developers] gstreamer audio unstable on the N770

Mon Sep 25 23:46:03 EEST 2006

Has anyone had any luck with more complicated N770 gstreamer apps?  I'm
playing with a custom streaming media app and it's unstable to say the
least.  With dsppcmsrc open multiple times the N770 is liable to throw
gstreamer errors and/or spontaneously reboot.  Dsppcmsink is acting
slighly better and I'm only getting tons of GST_MESSAGE_ERRORS "dsp
error cmd: 3, status: 10".  Throw in some glib warnings:
  GLIB WARNING ** default - WAIT_BUFFER: CMD: 1, ERROR: 4
  GLIB WARNING ** default - WAIT_BUFFER: CMD: 1, ERROR: 81
  GLIB WARNING ** default - WAIT_BUFFER: CMD: 3, ERROR: 10
  GLIB WARNING ** default - WAIT_BUFFER: CMD: 37, ERROR: 0
  GLIB WARNING ** default - WAIT_BUFFER: CMD: 37, ERROR: 38
  GLIB WARNING ** default - SET_PARAMS FAILED WITH STATUS 16534
  GLIB WARNING ** default - WAIT_BUFFER: CMD: 37, ERROR: 512
  GLIB WARNING ** default - Entered wait_buffer in error
After a few successful pipelines I'll see gstreamer errors about either
the dsppcmsrc or the dsppcmsink about "Could not open resource for
reading and writing."

The process also locks up for about two seconds when a dsppcmsrc
pipeline transitions to the GST_STATE_READY state which is rather
annoying as well.
