webcam-server returns the error "No supported colour palette found." - needs v4l2 support

[whitepixel]

Binary package hint: webcam-server

I'm trying to get webcam-server working on my Lenovo T61 laptop with an attached usb webcam running Ubuntu 8.10 amd64. lspci reports the following on my webcam:

Bus 002 Device 003: ID 041e:4036 Creative Technology, Ltd Webcam Live!/Live! Pro

My webcam works fine in cheese, camorama, xawtv; however, running "webcam-server" or "webcam-server -d /dev/video0" returns the error "No supported colour palette found.".

Running "mplayer tv:// -fps 15 -tv driver=v4l2" works great too, just not webcam-server.

I can repro this 100%.

Note that webcam-sever does not support v4l2:

I am experiencing the same problem, but only since the upgrade to intrepid. Webcam-server used to work without problems before (graphics card: ProSavage S3). What has intrepid changed? Does anyone know a good alternative to webcam-server?

[Oxenfrogga (tlatlik)]

Just the solution for people suffering the same problem. Type
export LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so
on the command line to prior to launching webcam-server. That will invoke the compatibility mode and will run webcam-server with intrepid.

Thank,
Harald

Any idea how to get this running with 9.04 desktop but without gnome installed? It works fine with the LD_PRELOAD on a full desktop machine - but when I installed from the alternate CD a commandline only machine, I still get the No Supported Colour Palette error - is it a gnome thing?

@weirdbeardmt
Just got it working for me. It works if i run the export and webcam-server in a bash script (not shell). This seems kind of strange, but it worked. Once i figured that out, i changed the init.d script to use bash and all is well. Here's the script i used.

#!/bin/bash -
export LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so;
webcam-server

webcam-server is no longer available in Ubuntu.
