GStreamer | gst-plugins-base | Ver: 0.10.12
Summary: audioresample seems to be causing segfaults
Product: GStreamer
Version: 0.10.12
Platform: Other
OS/Version: All
Status: UNCONFIRMED
Severity: critical
Priority: Normal
Component: gst-plugins-base
AssignedTo: gstreamer-bugs at lists.sourceforge.net
ReportedBy: szuk at telusplanet.net
QAContact: gstreamer-bugs at lists.sourceforge.net
GNOME version: Unspecified
GNOME milestone: Unspecified
Steps to reproduce:
I have a pipeline that uses an alsasrc to read audio from the mic and pass it
through an audioconvert and audioresample element and then into an adder. I
have a second bin that consists of filesrc, decodebin, audioconvert and
audioresample elements and that feeds into another sink of the adder. The
adder src outputs to an alsasink. I use this pipline to be able to play an
audio file at any time and have it mixed with the microphone data. I will
attach a test program that repeatedly plays a file while mixing it with the
mic. When I use any audio file (wav or vorbis tested), the program will
eventually cause a segfault that seems to always be related to
audioresample_buffer_queue_pull in audioresample.
