I just installed mirror 1.0-2 and it installed libspeex1 gstreamer0.10-plugins-good-extra, but when I run it I get:

/usr/bin/mirror: line 2: gst-launch-0.10: not found

something is missing?

EDIT: forgot to say that I've installed it via apt-get install mirror

How about swapping out v4l2src for v4l2camsrc.

Or use one N900, but have it plugged in to an external monitor.

Does /dev/video0 have this problem?

Also, please try v4l2camsrc. I just looked at the source, it's plenty different than v4l2src.

Ok, last pipeline. This one crops the top and the bottom so it fills the whole mirror window:

gst-launch-0.10 v4l2src device=/dev/video1 ! "video/x-raw-yuv,pixel-aspect-ratio=(fraction)1/1" ! ffmpegcolorspace ! videoflip method=4 ! videocrop top=60 bottom=160 right=122 ! xvimagesink force-aspect-ratio=true

EDIT: v4l2camsrc looks identical to v4l2src

Can we add a zoom feature so you can dial into that pimple? (Perhaps the swirly zoom from the browser

)

yep, you're missing gstreamer-tools (fixed in 1.0-3)

No, video0 works just fine (and has a lot better quality)

Thanks, some other update installed it, as it was already installed when I ran (now) apt-get install gstreamer-tools...

Anyway, it's working fine.
It's quite fast, but yes, the aspect ratio is to be fixed.

No way to take snapshots?

The zoom feature wouldn't be too hard, just crop the picture more and the remaining area will be hardware scaled to fill the screen.
