thanks that works great!

i start off with a gst_parse_launch()
videotestsrc
! video/x-raw-yuv,format=(fourcc)I420,width=480,heigh...
! fakesink name=mysink

If I want to replace the videtestsrc by some file, I need to specify
the whole decoder chain: eg.

 filesrc location=%s ! avidemux ! ffdec_mjpeg ! video/x-raw-yuv ...

this works as well - if the file is a mjpeg-avi :)

Can I use "playbin" or sth. to set up the demux/decoder?

I've tried to create the fake-sink with gst_element_factory_make() and
set the "video-sink" Property of playbin to it - but I do not get any
data when I probe on that pad! I also would prefer to the set up the
whole chain with gst_parse_launch(). (rather than messing with
g_object_set and gst_element_link_pads myself)

something like:
gst-launch playbin uri=file://... video-sink=fake-sink,name=mysink


TIA,
robin
