[MPlayer-users] TV-in on the Radeon 7500 QW

[Brian T Neltner]

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:

--------------------------------

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,
