Re: Working setup with two pci-e (ludovic pollet)

[ludovic p. <pl...@nn...>]

No, I have the same with mplayer and xine. XV seems to works fine on seco=
nd=20
head (xvinfo), but it just uses more cpu than when the card is alone.=20

I think it could be related to DMA... I suspect the nvidia drivers to do =
DMA=20
correctly only on first head and not on second...

I had a look at the xv code of the mga driver (the code which send data t=
o=20
video memory) : there is no dma here and it gives arround 35% cpu usage w=
hen=20
playing video. Since i have the same perfs on the pci nvidia, it is possi=
ble=20
that it uses the same method (copying data using cpu, without dma)...

The video I used to test was a capture from dvb-t (mpeg2). So you can get=
 the=20
same by playing a dvb for example... I'd really like to know if you have =
XV=20
working on all you heads with nice cpu usage...

Ludovic

The "cutting edge" is getting rather dull.
