Hi folks,

This is my first post here (I think?) and I'm going to make it an informative one :)

TL/DR:
Can someone please add this to the device ID list for the em28xx module?
Ion "Video Forever" - USB ID EB1A:5124, Card Type 9.
Confirmed as working with Xawtv and VLC, video source PAL composite
from a FLIR camera; S-video and audio untested as I have no suitable source to hand.
Test platform: Ubuntu 13.04 "Raring", kernel 3.8.0-21-generic
#32-Ubuntu SMP x86_64

The longer version:

I found this thing in a local Maplins under stock code A27KJ for the princely sum of £29.99 on special offer. According to the box, it's a "Video Forever VHS-to-Digital Video Converter" by ION (www.ionaudio.com). Strangely they don't list it on their website, so perhaps it's a special for Maplin?

lsusb says:

Bus 001 Device 084: ID eb1a:5124 eMPIA Technology, Inc.

The CD-ROM in the packet is apparently a driver set for an "ezcap" device ("Ezcap Video Grabber"), the INF file suggests it's an EM2860 series chip. For a laugh, I did this:

sudo modprobe em28xx card=9
echo eb1a 5124 | sudo tee /sys/bus/usb/drivers/em28xx/new_id

Which has the effect of loading the EM28xx driver with cardtype forced to 9 (which seems to be a generic EM2860-based device ID), then adding the new device ID (temporarily) to the module.

Re: EM28xx - new device ID - Ion

Thanks a lot. I just bought the same device from my local maplin as well as I felt lucky today! :)
Will try it soon and let you know how thing went.

Hi Philip,

Thank you for sharing this bit of info. I just bought what I think to be the very same device from local maplin too.
I have loaded it using your tweak.
Just like you the composite video input works just great, however I can't get any sound captured using the RCA audio leads.
The S-video doesn't work either :( (only one new v4l2 video source is registred loading the device driver).

I have done all my test using ffmpeg (and arecord to test audio only) but I am quite confident the outcome would be the same with other programs.

When loading the driver with card=9, I can see in the log:

"em2860 #0: Sigmatel audio processor detected(stac 9752)"

I wonder how much "detection" there is here under the hood, as I suspect the module param may have forced this (wrongly perhaps).
So as far as I am concerned, this ion thingy doesn't match exactly, the 9 card. How can I gather more informations about that device?

Regards Alex.

Hi Philip,

Very interesting post!

I also have an unsupported em28xx device, a MSI Digivox Trio (http://linuxtv.org/wiki/index.php/MSI_DigiVox_Trio) which I suspect to be similar to a PCTV QuatroStick nano. If I use the device ID from my stick and card number from the QuatroStick to forceload the em28xx driver, would that be safe? Or would I risk destroying the USB stick? I don't know if it's actually the same, all I know is that it shares many (maybe all) components.

Best regards,

Pim

So latest news... It seems this USB dongle actually has an EM202 audio processor instead of the Sigmatel reported in the logs.
I edited em28xx_audio_setup in em28xx-core.c accordingly and I can now capture audio using the composite interfaces.
However joy didn't last really long as I soon realised audio capture didn't worked as soon as I did open the video device at the same time.

To summarize:

ffmpeg -f v4l2 -i /dev/video1 /tmp/test.avi --> Works
ffmpeg -f alsa -i hw:1 /tmp/test/wav --> Works
ffmpeg -f v4l2 -i /dev/video1 -f alsa -i hw:1 /tmp/test.avi --> video OK but no Audio

Regarding the S-Video that doesn't work I think it's just a matter of card definition in em28xx-cards.c.... I will give a try several combination, nad possibly update the wiki in case I end up to a satisfactory result.

In any case I'd be happy to have any insight regarding the problem when audio doesn't work if video device is accessed at the same time.
