how to check the gstreamer plugins' performance bottleneck

Hi all,

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:

[hidden email]# opreport
CPU: CPU with timer interrupt, speed 0 MHz (estimated)
Profiling through timer interrupt
          TIMER:0|

      187 0.2244 ld-linux.so.3
      175 0.2100 libgthread-2.0.so.0

       39 0.0468 sh
       27 0.0324 libgstossaudio.so
        3 0.0036 sleep
        3 0.0036 librt.so.1
        2 0.0024 bash

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....

Is there way to trace into .so file to located the detailed code section? or any other ideas? thank you

Best regards

Re: how to check the gstreamer plugins' performancebottleneck

you can see which thread took much cpu by "ps", and locate the modules by log.

Hi Zhao Liang,

I use ps command to get the following results:

[hidden email]# ps -ma
PID TTY          TIME CMD
601 pts/0    00:06:35 mpegavdectest07
    - -        00:00:02 -

it would not display the object library at all,thus I still cannot locate the modules, is there any optional parameters I forgot? thank you

Hi zhaoLiang,

thank you help. I use the -L option and gdb ,now I can trace into the desired codes.
