[gst-devel] Some questions on dv1394src

[Yann Klis]

Hi,

Thanks for your example ! It works well here.
However, it eats 100% of my CPU which is a Pentium4 1,6 GHz (with or without
deinterlacing) and the video is very jerky ! :(

Is that normal ?
Is there any tweaks to improve the performance of gstreamer ?

I use the dv1394src from the gstreamer-dv debien package version 0.6.2-1

Thanks in advance !
