Description Christian Kirbach 2008-12-27 10:46:19 UTC

gst pipe used for encoding

audio/x-raw-int,rate=44100,channels=2 ! lame name=enc quality=0 vbr=4 vbr-mean-bitrate=320 vbr-min-bitrate=256 ! xingmux ! id3mux

can you confirm that this crash is caused by libid3tag and not by invalid usage of libid3tag by gstreamer?

Comment 1 Tim-Philipp Müller 2008-12-27 18:03:51 UTC

Hard to say what's going on here with the information provided.

Could you install the debug packages for gstreamer0.10-plugins-ugly/libgstmad and libgstid3tag?

Could you make a debug log (GST_DEBUG=*:5 whateverapp 2>dbg.log) and attach it here, bzip2'ed?

PS: you should use id3v2mux.

Comment 2 Christian Kirbach 2009-01-04 23:23:46 UTC

Ironically it does only crash with debugging disabled

Comment 3 Edward Hervey 2009-03-06 08:47:31 UTC

looking closer at the backtrace... the bug seems to be in mad (see #3, #7, #8).

The code of mad has changed a bit recently, can you try with latest releases (0.10.10) of ugly ?
