           Summary: libgstplay is *WAY* too slow
           Product: GStreamer
           Version: HEAD CVS
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins
        AssignedTo: gstreamer-maint at bugzilla.gnome.org

examples/gstplay/player file.avi

Take, e.g., a half-PAL [384x288 at 25fps] DivX 5 movie with mp3 audio and watch CPU
usage during playback in player. This takes >100% and playback stutters. On
gst-launch (gst-launch filesrc location=file.avi ! avidemux name=d .video_00 ! {
queue ! ffdec_mpeg4 ! ffcolorspace ! ximagesink } d.audio_00 ! { queue ! mad !
osssink }), it takes +/- 50%. I don't know or care what takes more than half of
my CPU during this file playback, but this is really far too much.

Summary: someone needs to heavily optimize and simplify libgstplay.
