I am capturing an image using gstreamer:

gst-launch-0.10 v4l2src ! ffmpegcolorspace ! pngenc ! filesink location=$date.png

I am then scping the file to a remote server:

scp $date.png remote:pics

What I would like to do is skip the file on the local filesystem step. Can I do something like

gst-launch-0.10 v4l2src ! ffmpegcolorspace ! pngenc | ssh remote "cat > pics/$date.png"

I am reading that

cat file | ssh uid@remotehost 'cat > /full/path/file'

should do what you need (replace cat file with your plumbing), but I am not sure how much of a hack is it (how will it perform on decently sized streams.

Alternative is to somehow mount the remote point - sshfs, cifs, nfs and then no magic is necessary.

The trick is getting the file contents to come out on stdout (thay is what I don't know, this is more of a gstreamer question than a how does ssh work question). The sshfs idea has merit though, that should be easy enough to setup –  Chas. Owens Sep 24 '10 at 17:41
