Hi all,
I have posted this in the video4linux list as well, so if this is the wrong
place for this, please let me know. Anyway, I have tried to get a KWorld
DVD Maker to work as a video capture device with no luck, but it seems it
should be supported. Following is what I have posted in the v4l list:
I have a Kworld DVD Maker that I don't think is the same as the Kworld
USB 2800 device mentioned in the em28xx.h card list (the one mentioned
has only PAL formats listed). It has an empia2860 chip and a saa7113h
chip inside (I took it apart). So far, I have tried adding this to
em28xx.h:
#define EM2860_BOARD_KWORLD_DVDMAKER 62
and the following to the card list in em28xx-cards.h:
[EM2860_BOARD_KWORLD_DVDMAKER] = {
.name = "Kworld DVDMAKER",
.em_type = EM2860,
.vchannels = 3,
.norm = V4L2_STD_NTSC,
.decoder = EM28XX_SAA7113,
.dev_modes = EM28XX_VIDEO,
.input = {{
.type = EM28XX_VMUX_COMPOSITE1,
.vmux = SAA7115_COMPOSITE0,
.amux = 1,
},{
.type = EM28XX_VMUX_SVIDEO,
.vmux = SAA7115_SVIDEO3,
.amux = 1,
}},
.tvnorms = {
{
.name = "NTSC",
.id = V4L2_STD_NTSC,
}
},
}
I am assuming most of this is right, although I am not sure what
vchannels is - so I left it at 3. I am guessing it is either 3 or
one. Also, it is NTSC and it has a video composite port - for a
picture, see here:

I have been trying to run it using a video input with the following:
mplayer tv:// -tv
width=360:height=288:device=/dev/video0:driver=v4l2:norm=NTSC
The terminal outputs:

and all I get while this is going on is a green screen. Anyone have any
ideas or can anyone point me some pointers so I can figure out how to
get this to work or how to debug it? It seems it should work since I
believe both chips are supported under v4l2. I know the device works
because I have used it under Windows.
Could it have something to do with the following line from above?:
v4l2: ioctl query control failed: Invalid argument
Thanks for any help!
