Description j^ 2006-06-23 14:31:26 UTC 
trying to convert a dv file to theora with this command:
gst-launch-0.10 
 filesrc location=input.dv ! decodebin name=decode decode. ! \
 queue max-size-buffers=100 max-size-time=0 max-size-bytes=0 ! \
 ffmpegcolorspace ! ffdeinterlace ! ffmpegcolorspace ! \
 videobox top=8 bottom=8 left=4 right=16 ! videoscale method=1 ! \
 video/x-raw-yuv,width=320,height=240,pixel-aspect-ratio=(fraction)1/1 ! \
 videorate ! video/x-raw-yuv,framerate=(fraction)25/2 ! \
 theoraenc quality=16 sharpness=2 ! oggmux name=mux ! \
 filesink location=output.ogg \
 decode. ! queue max-size-buffers=100 max-size-bytes=0 max-size-time=0 ! \
 audioconvert ! audio/x-raw-float ! audioresample ! \
 audio/x-raw-float,rate=22500,channels=1 ! vorbisenc quality=-0.1 ! mux.

i get a segmentation fault after about 4 minutes. 

here is a backtrace on the core file:
(gdb) bt

Any chance you could get a stack trace with debugging symbols (for GStreamer at least)?

Would also be great if you could run this through valgrind (with debugging symbols).

does the file play without segfaulting with:

 gst-launch playbin uri=input.dv

just to figure out if there is no mem corruption somewhere else.

looks like with my current dv files this no longer happens with the pipeline that caused the segfault,
i will close the bug and test gst-launch playbin uri=input.dv if i encounter the problem again...
