Okay, I looked through all the archives and couldn't find anyone that is
having the problem I am, I checked all the documentation, and have played
with this one for a few hours.
I'm using Debian sid with kernel 2.4.21rc1, afterstep as a window manager.
I have my Radeon connected to a VCR via the composite plug, and am trying
to capture video sent from the VCR to the computer.
I am running the current CVS version of the GATOS km, drm, and
XFree86-4.2.0-16 ATI drivers. I am running XFree86-2.4.1-6 from a debian
package.
I can view video fine with avview or xawtv, although neither is capable of
recording it... avview doesn't compile when I include ffmpeg support and
when I try capture with xawtv from the debian package, it claims grabbing
is not supported. But regardless, the radeon composite input is
definately getting a signal.
I'm not completely sure what options I should be using (at least as far as
which input is appropriate-- the man file doesn't list what the
correlation is), but I've tried all the available input possibilities.
Here's the output for one attempt. I've tried with -tv on:... instead of
the tv://. I've also tried all the input=<foo> options and tried without
channel=<foo>:

--------------------------------
In addition, dmesg tells me the following:
--------------------------------
Purging transfer queue

km: closed stream, 0 buffers captured

--------------------------------
Does anyone know how to make mplayer and the GATOS drivers happy? What
is ioctl get channel? The errors seem to be identical regardless of what
arguments I give mplayer.
Thanks for any advice,
-Brian
