However, I haven't seen any change in the behaviour I described above. To be sure, I downloaded ivtv-utils-1.3.0 directly from http://dl.ivtvdriver.org/ivtv/archive/1.3.x/ivtv-utils-1.3.0.tar.gz and compiled a v4l2-ctl binary. Here are three consecutive commands and their outputs. # ./v4l2-ctl -b cc --verbose VIDIOC_QUERYCAP: ok VIDIOC_S_FMT: ok # ./v4l2-ctl -c stream_vbi_format=1 --verbose VIDIOC_QUERYCAP: ok VIDIOC_S_EXT_CTRLS: ok # ./v4l2-ctl --get-sliced-vbi-out-cap --verbose VIDIOC_QUERYCAP: ok VIDIOC_G_SLICED_VBI_CAP: failed: Invalid argument modinfo ivtv shows that the version is 1.4.0. Is there something I can do to diagnose this problem? -- Christopher Neufeld Home page: http://www.cneufeld.ca/neufeld "Don't edit reality for the sake of simplicity" _______________________________________________ ivtv-devel mailing list [email protected] http://ivtvdriver.org/mailman/listinfo/ivtv-devel
