    EffecTV problems

    I try running effectv and I get the following error:
    Code:
    v4lsetchannel:VIDIOCSCHAN: Invalid argument
    Video initialization failed.
    My Webcam seems to work fine, I found a Debian bug report that seems similar. http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=513883
    i'm using uvcvideo,videodev,v4l2_compat_ioctl32,v4l1_compat, vloopback as kernel modules
    I'm on Lucid, 10.04 64 bit
    any help would be nice.
    Is this a bug?

    I have seen this problem with kdenlive, the solution was:
    LD_PRELOAD="/usr/lib/libv4l/v4l2convert.so" kdenlive
    try
    LD_PRELOAD="/usr/lib/libv4l/v4l2convert.so" effectv

    didn't seem to work(e.g. the effectv). also kdenlive has some minor glitches but seems to work fine. would it make a difference that I use 64bit?
