Hello, thanks for your answer, but it keeps crashing. However, the logs are showing some interesting messages:
[...] org.opencastproject.capture.pipeline.bins.UnableToCreateElementException: Epiphan_VGA2USB could not create v4lsrc at [...] If I execute: gst-launch --gst-debug-no-color -e --gst-debug=2 v4lsrc device=/dev/vga2usb0 ! fakesink I get this error: 0:00:00.027119101 2438 0x1aad080 ERROR GST_PIPELINE ./grammar.y:661:_gst_parse_yyparse: no element "v4lsrc" 0:00:00.027165534 2438 0x1aad080 ERROR GST_PIPELINE ./grammar.y:929:_gst_parse_launch: Unrecoverable syntax error while parsing pipeline v4lsrc device=/dev/vga2usb0 ! fakesink ERROR: pipeline could not be constructed: no element "v4lsrc". I've tried the v4l2src and it says that it isn't a v4l2 driver. I'm thinking that maybe the problem is that I haven't the v4lsrc plugin for the gstreamer. # gstreamer-properties [...] # gstreamer-properties-Message: Skipping unavailable plugin 'v4lsrc' [...] Is there any easy way to install the v4lsrc plugin for the gstreamer 0.10 in a Ubuntu 10.10 x86_64?
