Hi all!
v4l2loopback is working pretty nice! thanks for the awesome work, Iohannes! I did suceed with the "v4l2sink" element (st-launch videotestsrc ! ffmpegcolorspace ! v4l2sink device=/dev/videox) .Now, the doubts:
. Which apps you know can already write to v4l2 devices ?
All applications using gstreamer and v4l2sink ? You can find some application using gstreamer here : http://gstreamer.freedesktop.org/apps/
. What's the name of the gem object for the v4l2loopback ?
There is no such object in GEM but in pdgst. And the name of this object is [v4l2sink].
that is one possibility.
I 'm using pd-extended from yesterday auto-build (GEM: ver: 0.93.SVN rev3703 GEM: compiled: Feb 11 2011) and get no valid object for "recordV4L2" .
For example, you can use [pix_video] with [pix_writer] or [pix_write] or [pix_record]. But what do you want to do exactly ?
you should be able to use [pix_record] with v4l2loopback. just do:
- create [pix_record]
- check at the console whether it prints something like "[pix_record]:
backend #1='V4L2'" (this will only happen the first time you create a [pix_record] object for hygienic reasons)
Good to know. But i don't have this in the console when i create [pix_record] (even after to have created the gemwin and with a gemhead). GEM: Graphics Environment for Multimedia GEM: ver: 0.93.SVN rev3578M GEM: compiled: Jan 3 2011 I need an other version of GEM ? ++

- if so, continue
- set the codec to "v4l2" and the output filename to /dev/video1 (or
whatever your loopback-device is). something like [codec v4l2, filename /dev/video1, record 1( should do the trick.
