<DIV>Hi all,</DIV>
<DIV> Recently,I noticed that my gstreamer application
take a lot of CPU resource, my platform is Ti
dm644X(arm9+dsp), and I have used oprofile to get the
following reports when playing a D1 mpeg2 ts file:</DIV>

<DIV>and I have used a 320x240 mpeg2 ts file and a D1 mpeg2 ts file as the
source, when use the former,the gstreamer application take 50% of CPU while
the later take almost total CPU, so I guses the bottleneck maybe be caused by
the flutsdemux....</DIV>
<DIV> Is there way to trace into .so file to located the
detailed code section? or any other ideas? thank you</DIV>
