need somagic drivers easycap

Mon Jan 07, 2013 10:24 am

hi everyone. i'm new to this forum. need some help.
i've a 1/3'' sony ccd pal camera cxd3142r . it has two wires one for power supply 12V and another BNC.
Now i got bnc to rca male converter cable and connected to easycap D60 v3.1c smi grabber chipset.
now the question is how can i get easycap working with my pi model B???
after lsusb it detects and shows the easycap. i've mplayer installed and as well as ffmpeg.
how do i capture the video????

Yes, I am very interested in how you made it.
So far I've managed to compile the drivers but I have the same error as you :
Unexpected block, expected [aa aa 00 00] found [00 00 00 00]

Definitely very interested. It's my next planned project - if you could save me from reinventing the wheel it'd be awesome! Thanks!

Sorry guys.. misunderstood.. i've compiled the drivers successfully but the unexpected block error comes... its because of USB issue. the kernel doesn't recognize the data from easycap. Have to try with some other kernel. i'm trying with different kernels. will intimate soon if it works.

I said the steps for compiling drivers alone.. the result is when we work with sudo somagic capture, unexpected block error comes. some guys didn't know to compile drivers, thats y i posted like that only for compiling drivers. sorry :idea:

Hello,

I'm trying to do the same thing.

I've tryed with SmiUsbGrabber3C.sys driver and get the same error than you.
With my easycap, i receive a cd and the driver is SmiUsbGrabber3E.sys.
I did a fresh install of last rasbian os, install/compile somagic & somagic tools and install SmiUsbGrabber3E.sys firmware.

When i do a somagic-init, my usb device disapear and no new device appear.

Anyone have an idea ?

P.S. to list my usb devices i used :
ls /dev
lsusb
usb-devices I get

I'm having the same issue. I compiled successfully but just get the unexpected block error.

I've tried somagic and the capture device on a laptop running Mint and all works fine (although I only tested it for a few minutes), so it's not a dud device.

I noticed there was a discussion here:

https://groups.google.com/forum/?fromgr ... 6YOygTXtqs

about running somagic on the Raspberry Pi, which suggests it's a Pi or ARM issue, possibly specific to the Pi kernel.

I have wondered if it's a power issue, perhaps the Pi's USB ports aren't giving enough power. Might be worth trying it with a decent powered hub.

In the mean time I'm looking for other Easycaps, there are at least 4 versions of these all with different chipsets, with different levels of Linux support. More info here:

Thanks. You're true, with a powered usb hub, the device doesn't disaperar anymore.
The somagic-capture --test-only doens't return error message.

Still working on it...

It's a problem with isochronous USB on RPi (see http://www.raspberrypi.org/phpBB3/viewt ... =33&t=9927).

Hey guys, I thought I'd share my experience with a Somagic device too. I have the 4-input model (1c88:003f), all testing was done using a powered hub.
  • Pi model B, using easycap-somagic-linux drivers: Unexpected block errors
  • Pi model B, using kernel driver from drgr33n: getting "select timeout" errors and random freezes
  • BeagleBone Black, using easycap-somagic-linux drivers: I was able to make it work, however, I couldn't get stable image output - whenever I tried to capture a frame using mplayer, I could only get partial / broken frames. The same calls/parameters worked fine on an x86 linux with the device.
I needed this for a project which involves a few cameras (hence the 4-input model) and interval-based static captures (no video stream) only. Anyway, for now I will probably give up as I ran out of time. Does anyone know if the other chipset clones also come in 4-input versions? I think I've seen reference to an STK1160-based device with 4 inputs, but with em28xx ones, the chances of making it work on Pi or BBB would probably be better right? Thanks for any input/ideas.

raspberry pi with composite video input would be awesome.

It would, but useful only to a very small group of Pi users, and thus, it wouldn't justify the cost increase (development / manufacturing) I guess... :|

Does anyone have a copy of SmiUsbGrabber3E.sys or SmiUsbGrabber3F.sys? I can't find my driver disc and have search all over the net but can only find the 3C variant.

The Driver Disk would not inlude ARMv6 Drivers, plug the device into the RPi and post output of lsusb

No but the linux driver requires firmware which you extract from the windows driver (.sys file)

I've got the "F" one in my Projects folder from the time I last played with it - I'll send you a PM with the download link shortly.
