<div dir="ltr">Hi Mark, Thanks to GEtrans I can now easily extract a sub part of a movie so that 's cool for my needs. ** This cammand works fine to cut a sub part of 15 sec of a movie. :P entrans.py --ignore-prop '.*sink*.' -s seek-key -c 25-40 --dam -- --raw filesrc location=movie.avi ! avidemux name=demux avimux name=mux ! filesink location=sub.avi demux.video_00 ! queue ! dam ! queue ! mux.video_0 demux.audio_00 ! queue ! dam ! queue ! mux.audio_00 ** The following seems to work but I cannot play the result sub2.avi: entrans.py --ignore-prop '.*sink.*' -s seek-key -c 25-40 --dam -- --raw filesrc location=movie.avi ! avidemux ! queue ! dam ! queue ! avimux ! filesink location=sub2.avi ** And the following causes a seg fault: entrans.py --ignore-prop '.*sink.*' -s seek-key -c 25-40 --dam -- --raw filesrc location=movie.avi ! avidemux ! dam ! avimux ! filesink location=sub3.avi I am sure I am not using correctly entrans in the 2 last pipelines :P (Also it was cool to see an element "detectinter" ...) Sincerely J.I. <div class="gmail_quote">2008/9/11 Mark Nauwelaerts <<a href="mailto:manauw@skynet.be">manauw@skynet.be</a>> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> The exception is most likely an effect of bug <a href="http://bugzilla.gnome.org/show_bug.cgi?id=540221" target="_blank">http://bugzilla.gnome.org/show_bug.cgi?id=540221</a>, the fix for which may not be present in your gst-python (or otherwise another bug very much like it :) ) It can be worked around (IIRC) by adding the option --ignore-prop '.*sink.*' (so it does not access the sink's property leading to the crash). I also have some doubts about the chances for success of the pipeline (e.g. no dam in it, entrans uses this element to direct the seek to ...) Using a more "conventional" pipeline as exampled in the link mentioned below may be advisable.
