USB Video DVD Maker for Linux

Today I borrowed a USB video device, just to see if I can get it working on Linux. And I did! The device's package shows that is supports PAL (720x576@25fps) and NTSC (720x480 @ 30fps), but not much more.

According to lsusb, the device is built by eMPIA Technology, Inc and it has id eb1a:2861. Because I have another webcam attached, the device is connected to /dev/video1 is a character device with major 81 and minor 1. In the /sys filesystem, there's information on the device. I can find the right node using the next command:

cd /sys/dev/char/81:1

This is a symlink to (in my case) /sys/devices/pci0000:00/0000:00:1d.7/usb2/2-5/2-5:1.0/video4linux/video1. In this directory, I find some more useful information. The file name tells me the device is actually a em28xx-based device.

The device has 2 inputs: a serie of RCA connectors with a composite signal and a SVideo connector. This is represented by showing two "sub-devices". The composite signal is /dev/video1, while the SVideo connector is /dev/vbi0.

To display the screen of my Sony* HDR-SR11 camera, I use the command:

mplayer -cache 128 -tv driver=v4l2:device=/dev/video1:input=1:width=720:height=576:outfmt=i420 tv://

* Yes, a Sony. And I'm really sorry. I bought it several years ago. I'm boycotting Sony nowadays.
