EffecTV problems

[duke.tim]

I try running effectv and I get the following error:

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

[duke.tim]

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?

[xc3RnbFO8P]

would it make a difference that I use 64bit?
Yes :

LD_PRELOAD="/usr/lib32/libv4l/v4l2convert.so" effectv

[duke.tim]

ERROR: ld.so: object '/usr/lib32/libv4l/v4l2convert.so' from LD_PRELOAD cannot be preloaded: ignored.

so I moved it to /usr/lib/ didn't work so i've removed them now. any ideas...

[xc3RnbFO8P]

Try this:

LD_PRELOAD="/usr/lib/libv4l/v4l1compat.so" effectv


rob@ubuntu:~$ LD_PRELOAD="/usr/lib/libv4l/v4l1compat.so" effectv

I've tried the v4l1compat solution in UBuntu GNU/Linux 11.04 (Natty Narwhal), and doesn't work:


effectv

v4lopen:VIDIOCGCAP: Invalid argument
Video initialization failed.


LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so effectv

v4lsetchannel:VIDIOCSCHAN: Invalid argument
Video initialization failed.
