It might be something different too, it just popped into my mind I read
such a
few weeks ago.
I just checked the code. The message is coming directly from the capture
extension. ::Capture::Open internally uses the set_color_conv function to
select the palette. It tries RBG24 first, then BGR24, and if both fail,
it
will try to find a convertor from 'just what is available' to RGB24. If
none
is found, it will return -1 to indicate failure.
If aMSN is compiled with DEBUG enabled, this function will write a line
to the
console for every converter it tries. so having console output (from aMSN
with DEBUG of course) might be very helpful.

Hi,
I don't think so, v4l-info only reports RGB24... but you think it might
be
that ? so we simply need a foreach palette... ?
