Bad Jpeg quality

Hi all,

I'm using gstreamer to display rtsp stream from IP camera. The stream is
jpeg encoded. I use this pipeline:

> *gst-launch-0.10 rtspsrc location=rtsp:// ! rtpjpegdepay ! jpegdec idct-method=islow ! autovideosink
> *

But the quality is very bad. It's look like a lazy mode for decoding the
jpeg stream, I tried different parameter for idct-method property but
nothing changes.
The stream has better quality rendering with VLC or Qt+Live555.

Is there a way to improve the visual quality?
