           Summary: GStreamer performance issues
           Product: GStreamer
           Version: 0.10.x
          Platform: Other
        OS/Version: All
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: Normal
         Component: gstreamer (core)
        AssignedTo: gstreamer-bugs at lists.sourceforge.net

     GNOME version: Unversioned Enhancement
   GNOME milestone: Unspecified


The performance of GStreamer-based applications seem to lag behind other
(potentially less flexible) media frameworks.  I am hoping this bug may be used
to discuss these perceived performance issues.

In 2003, I was using the Xine application and libraries to play DVD's.  The
system in question was a G3-based iBook.  I was able to watch entire movies
with
no lag.

Today, I have replaced my old G3 with a G4-based iBook.  Playing DVD's using
gst-launch does not work well.  The video immediately starts to lag behind the
audio.

I am using the following command to play DVD's:

gst-launch dvdreadsrc title=1 ! decodebin name=dvd dvd. ! queue !
ffmpegcolorspace ! xvimagesink dvd. ! audioconvert ! queue ! alsasink

The command top shows that gst-launch is maxing out the system's CPU and
appears
to be dropping frames.
