I finally got it to work with gst-1.0 with great performance (about 100 ms latency) (I have to remove gstreamer-vaapi module) but gst-1.0 doesn't seem to work with v4l2loopback
so I'll try to make a gst-0.10 pipeline to do the same and use v4l2loopback or pdgst or maybe it's time to dig into pdgst and build it with gst-1.0... I'll let you know what works + a -- do it yourself http://antoine.villeret.free.fr 2014-12-27 8:38 GMT+01:00 IOhannes zmölnig <[email protected]>: > I would use a gstreamer solution that outputs to a v4l2loopback device, > read by gem.
