That would be great ! I used to own a DC10 a long time ago, and the
zoran driver was the first one I tried to hack when I moved to Linux.
I'd love to see it getting maintained. Please let us know if you need
any help getting st

Here's a patch which uses __func__ along with %s in the printk's. The debug

faster.

It looks like you haven't configured your kernel tree (make config or make
menuconfig). You should also ru
be nice to use them, as moving the
subtitles off the picture will improve compression, and will allow the user

Any help would be appreciated.

Hi,
Could anyone tell me how yuvscaler handles interlaced material ? Does it
deinterlace it before applying the scaling ? If so, is there a way to turn
that off for progressive input ? And if not, doesn't it have an impact on
quality ?

MPlayer outputs to a file or a named pipe, not to stdout.

If so, you can tell lavrec where your video device is by setting
