EasyCAP002 concurrent inputs

[GoogleCodeExporter]

Screenshots of the windows software for the EasyCAP002 suggest that it's 
possible to capture from all 4 inputs simultaneously, though I assume at 1/4 
the standard NTSC resolution.

It would be super cool if this linux software supported that mode :)

(I have capture from any of the individual inputs working fine from a 
"1c88:003f Somagic, Inc." device)

Windows software does not capture all 4 inputs at the same time. It is only 
able to capture one input at a time, so video will be switching every 1 second 
beween 1-4 inputs

Aah, that makes sense.  In that case, how hard would it be for the 
somagic-capture program to do the same, either on a timer, or every N frames, 
or based on some external signal (keyboard input, SIGUSR1/2, etc)?

IIRC, it switches every frame, so you get 7.5fps (NTSC) 6.25fps (PAL). That'd 
be nice if somagic-capture could do it. If I understand correctly, this would 
require a usb trace from this kind of capture to figure out the sequences of 
i2c commands to write?

I have a Windows 7 installation on this system that can boot natively or in 
vmware, and four video sources handy, so if someone can provide instructions on 
how to capture the trace, I'll happily do it.

I have problems in the video images. Photo in site below. I already tried all 
examples and also use mplay and vlc.

For example:
somagic-capture | mplayer -vf yadif, screenshot -demuxer -rawvideo rawvideo 
"pal: format = UYVY: fps = 25" -aspect 4: 3 -
