Hi Robert, As you know its a development camera... I think my camera need some fixing.. my hardware decoder does not work with H.264 stream directly... I added h264parse element before h264 decoder in gstreamer pipeline to make it work.

The latest gstreamer-ffmpeg did not work for me for the FaceVsion Touchcam E1.
