CPU Usage excessive. TSDemux->MPEG2->resize->mpeg4->tsmux->send

[Richard]

Hi All,

I am running a DVB->Transcode->MPEG4->stream solution and I am getting
really bad CPU usage.

 3659 root      20   0  386m  37m 9220 S  134  1.4   0:27.47 DVBStream
According to top, its using 134% !... when no transcode is taking
place (DVB->IP SEND) top reports 5% CPU usage.

Is there a way to profile what is sucking the life out of the CPU ?
(The machine is a Dual Core Athlon X2 when using VLC I can
trancode/stream using 20% CPU)


How can I profile the pipeline?
Richard
