It seems to me that there are two identical command lines in the upstream bug report. Or did I misunderstand something? I tried with $ gst-launch-1.0 filesrc location=wave_anim.avi \! avidemux \! avdec_mjpeg \! autovideosink $ gst-launch-1.0 filesrc location=wave_anim.avi \! avdec_mjpeg \! autovideosink to no avail. Both pipelines abort with errors (although they spit different error messages). I apologize, but I am totally clueless about the meaning of GStreamer pipelines...

Which is the one corresponding to jpegdec? Please let me know: thanks a lot for your time and patience! -- http://www.inventati.org/frx/ There's not a second to spare!
