Alf: Add Elgato Video Capture

Elgato is a German based [[List of Device Vendors|vendor]] of DVB devices that are targeted towards Mac OS-X users. Their OS-X based software is quite well-designed, maybe it's worth a look as source of inspiration for other DVB application developers and GUI designers.

Elgato initially provided only [[FireWire]]/[[IEEE1394]] DVB receivers (see [[DVB-T IEEE1394 Devices]]), but have since branched out with more [[interface chipsets|interface options]].

Alf: Add info about Elgato Video Capture V2

This article is about the [[USB]] Video and Broadcast Audio decoder family CX23100/1/2 from [[Conexant]].

==Overview/Features==
The CX23102 has all the features that other chips in the family share. The CX23100/1 are cut-down versions of this chip.

===CX23102===
*USB 1.1/2.0 support
*Video broadcast formats:NTSC/PAL/SECAM
*Audio broadcast formats:BTSC/EIAJ/A2/NICAM/AM
*24 [[GPIO pins]]
*3 I2c master busses
*Inputs:
**Stereo Analog Audio
**Two Chroma/One PrPb/One SIF
**Four CVBS/Luma Inputs
**Tuner
**Serial Transport stream
**Parallel/Serial Transport stream
*Outputs
**I2S 16/24 bit 32/44.1/48kHz
**Audio Master Clock

===Feature comparision chart===
According to Conexant product brief, there are following differences between versions of chipset

==Linux Support==
The CX2310x series of chips is supported in Linux through the cx231xx driver. There are two reference designs by Conexant that are explicity named in the driver. All other cards are listed as 'unknown'

==Boards==
* [[Hauppauge_USB-Live-2]]
* Elgato Video Capture V2 - this board works with the cx231xx driver, using a patch sent to linux-media mailing list on 28/11-2012. Note that Elgato Video Capture V1 uses [[Em28xx_devices]] driver.

Hauppauge USB-Live-2

2012-11-28T18:37:49Z

Alf: The cx231xx driver in linux kernel 3.6 probably works fine with this device

[[Image:Hpg_usb_live2_top.jpg|thumb|200px|Top view of PCB]]
[[Image:Hpg_usb_live2_bot.jpg|thumb|200px|Bottom view of PCB]]

'''Hauppauge USB-Live-2'''

As of 4/29/2010 does not work with cx231xx driver.

KernelLabs has released a driver containing preliminary support for this device. See the [http://www.kernellabs.com/blog/?p=1445 KernelLabs announcement] for more details.

As of 11/28/2012, the cx231xx driver in 3.6 kernel probably works fine with this device. At least the same config as is present in the driver fot the Hauppauge USB-Live-2 has been found to work fine with a Elgato Video Capture V2 board, which uses the same CX 23102 chip and has very similar lsusb output.

==Overview/Features==

* USB Interface
* S-Video and Composite Video Input
* Stereo Audio Input

===Components Used===
* Conexant CX23102 (All in one Video/Audio to USB IC)
* SOIC-8 Marked as ATMEL943 02B 1 Z9G3334B, Use is unclear.

===Identification===

==Attempts to make it Work==
This section will be a bit non-wiki like but hopefully someone will find it useful.

There is a driver in kernel for the cx231xx series chips. Currently there are only board definitions for some reference designs. I added a new board definition for this board with as much information I could trace on from PCB. The driver begins to load but starts spitting out lots of errors pertaining to communication issues.

I managed to get it to the point that the driver loaded and attempted to initialize the board but I was getting intermittent EPIPE errors that caused initialization to fail. To get that far I had to comment out a bunch of the drivers attempts to initialize an external tuner (which this card doesn't have). The board def was set to TUNER_ABSENT however in many places it doesn't appear that there was a check to see if a tuner is there before calling some of the I2C functions to talk to it. Tracing the loading process there also appeared to be sections stubbed out that would be needed for this card's arrangement. I don't have any previous experience with these types of chips and was unable to find a full datasheet for the Conexant chip so am at a road block in trying to get it working alone.

It would appear in general that the cx231xx driver is in a bit of a skeleton state and only was developed to work on the reference designs.
