[Gstreamer-openmax] Gstreamer Pipeline Optimisations ?

[Nitin P. <nit...@gm...>]

Hi,

Currently, a typical gstreamer pipeline looks like

>gst-launch  filesrc location=XYZ ! demuxer !  decodebin ! ffmpegcolorspace
! videobalance ! videoscale ! ximagesink.

The movement of data accross is enormous for a D1 or HD resolution as the
pipeline passes YUV/RGB data which is very huge.

Is there any optimization possible or used which uses *pointers* to pass
rather than the huge mem-copies involved?


Thanks,
Nitin
