Hi!
Xvidcap is great. I've been trying to use it to record screencasts, and have hit a problem on several Ubuntu machines (compiled the latest version from svn) where the GUI just locks up a few seconds after I start recording.

Is there any kind of debug information I can provide?

    what version of ubuntu? Hardy?
    I'm on gutsy with no such problems. Have heard about Fedora 8, though where such problems were related to bugs in libX11 and libxcb.
    Please provide the output of "ldd <path-to-xvidcap>/xvidcap"

    Hi,

    I had the same problem in Fedora 8, and it was related to this bug:

    Bugzilla Bug #254144 (not thread-safe?), which made me
    to downgrade to the libX11 from F7.

    https://bugzilla.redhat.com/show_bug.cgi?id=254144

    I packaged xvidcap-1.1.7 rc1 for F8, but I did not test it yet
    with an updated libX11. But it is working fine with the downgraded
    libX11.

    Can reproduce this behaviour on hardy now (that I have a hardy machine).
    It can be solved by the following before starting xvidcap:
    export LIBXCB_ALLOW_SLOPPY_LOCK=1
    This also confirms that the underlying issue is the known xcb issue, not an xvidcap issue. Fedora e. g. has sloppy lock on by default, now.
