[MPlayer-users] How to use overlay mode with MPlayer?

[Jouni.Lohikoski@iki.fi]

1)
As DMA access in rivatv driver (for nVidia based capture/video cards)
does not work, only way in the slow(ish) machine to show video-input
is to use overlay mode. xawtv uses this automaticly.

How an overlay mode can be used with mplayer?

Command line:
mplayer -vo xv -tv driver=v4l:norm=PAL:input=0:outfmt=uyvy:width=704:height=576:fps=25:device=/dev/video0 -vf pp=fd tv://

Mplayer says:
"

Selected driver: v4l
 name: Video 4 Linux input
 author: Alex Beregszaszi
 comment: under development
Selected device: rivatv video
 Capabilites: capture overlay chromakey
 Device type: 25
 Supported sizes: 64x32 => 704x576
 Inputs: 2
  0: Composite:  (tuner:0, norm:pal)
  1: S-Video:  (tuner:0, norm:pal)
Using input 'Composite'

But it obviously is trying to use capture mode (Capabilities) as nothing
but black window is showed, the same as if xawt would be forced to use
capture mode instead of overlay mode.

2) 
There is a mail archive in < http://mplayerhq.hu/pipermail/mplayer-users/>
Why there is no search capability in there, so one could "easily" find
if something has been asked and answered before? Is there some other
place where the mail archive could be queried? (except asking again on
the list)
