Description W. Michael Petullo 2010-11-24 15:18:38 UTC 
I am using the following MacPorts packages on Mac OS X 10.6.5:

gst-plugins-bad                @0.10.20        gnome/gst-plugins-bad
gst-plugins-base               @0.10.30        gnome/gst-plugins-base
gst-plugins-good               @0.10.25        gnome/gst-plugins-good
gst-plugins-ugly               @0.10.16        gnome/gst-plugins-ugly
gstreamer                      @0.10.30        gnome/gstreamer

Running the following pipeline crashes:

gst-launch filesrc location=/tmp/in.mp3 ! decodebin ! audioconvert ! flacenc ! filesink location=/tmp/out.flac

with:

Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
Caught SIGSEGV accessing address 0x728f1e

+ Trace 224814

Thread 2 (process 82420)

  • #0 __semwait_signal
  • #1 nanosleep
  • #2 g_usleep
  • #3 find_highest_version
  • #4 <signal handler called> 

Replacing flacenc with lame crashes in the same manner.

The following pipeline does not crash (just decode and convert, don't encode):

gst-launch filesrc location=/tmp/in.mp3 ! decodebin ! audioconvert ! filesink location=/tmp/out.flac
Comment 1 W. Michael Petullo 2010-11-29 04:26:41 UTC 
However, "gst-launch filesrc location=/tmp/in.mp3 ! decodebin ! audioconvert ! vorbisenc ! oggmux !
filesink location=/tmp/out.ogg" works fine.
Comment 2 Sebastian Dröge (slomo) 2010-12-12 15:54:21 UTC 
Could you get a backtrace of all currently running threads? Use the following in gdb for this
thread apply all bt

Hey,

i'm trying to test the x264 encoder with one of the examples command that is provided on the plugins page:
gst-launch -v videotestsrc num-buffers=1000 ! x264enc pass=quant ! matroskamux ! filesink location=videotestsrc.avi

and i get the same error. Here's the gdb output for 'thread apply all bt' in gdb:

0x00007fff86777e92 in select$DARWIN_EXTSN ()
(gdb) thread apply all bt

+ Trace 226311

Thread 2 (process 54030)

  • #0 __semwait_signal
  • #1 nanosleep
  • #2 g_usleep
  • #3 main 

i'm using the gstreamer + plugins that are available in macports, i.e. 
  gst-plugins-bad @0.10.21_0 (active)
  gst-plugins-base @0.10.32_0 (active)
  gst-plugins-gl @0.10.2_1 (active)
  gst-plugins-good @0.10.27_0 (active)
  gst-plugins-ugly @0.10.17_0 (active)
  gstreamer @0.10.32_1 (active)
  x264 @20100603_0

Setting the environment variable "ORC_CODE=backup" fixes this issue. See also bug #628415.
