At your rooted command line:
(make sure FS is rw) mount -o remount,rw / gst-launch camsrc ! palmvideoencoder ! filesink location=/media/internal/downloads/foo.mp4 mount -o remount,ro /
- No GUI - No sound (need a muxer plugin? verify alsasrc works) Frame rate seemed pretty decent too.
other useful gstreamer commands:
gst-inspect (shows list of sources to pipe through, mostly decoders/demuxers)
Additional reference from XO Laptop site:
Currently looking at ways to use the camera preview pipe as a method of video recording through the WebOS GUI by diverting it to the filesystem.
