DVB
Firewire
HDMI
Hauppage Colossus
- still no drivers for linux (only a testing project)
USB
Conceptronics Composite
- lsusb
Bus 001 Device 002: ID 1b80:e34e Afatech
- using em28xx module
- configuration card 9 ('Pinnacle Dazzle DVC 90', which works)
modprobe em28xx card=9
- Insert the device type:
echo 1b80 e34e > /sys/bus/usb/drivers/em28xx/new_id
mplayer tv: //-tv driver=v4l2:width=640:height=480
- If you have multiple devices (for example a webcam), the USB device will not be the default /dev/video0 and you have to explicitly mention the device path when opening the video stream. For example:
mplayer tv:// -tv driver=v4l2:device=/dev/video1:width=640:height=480
Note that if you use the NTSC standard, you will get a green overlay over the image. The composite video must be PAL standard to work properly.
5. Video can be recorded uncompressed by adding the following option:
mplayer tv:// -tv driver=v4l2:width=640:height=480 -vo pnm
The individual frames are then saved as *.pnm files. Deinterlacing options can be viewed by typing:
mplayer -pphelp
An example of a deinterlacing filter when recording raw video:
mplayer tv:// -tv driver=v4l2:width=640:height=480 -vf pp=ci -vo pnm
