Is it possible to import a real time video from CCD Camera with BNC cable on Matlab ?

I would like to capture one image per second from a real time video automatically. The video from CCd Camera with BNC cable is on the software AverTV. I wrote a code on Matlab but I didn't find how I can import this video into Matlab in order to do screenshot.

Are you using one of the AverMedia conversion products? If so, which one?

What do you mean by 'AverMedia conversion products' ? I don't understand

[Walter Roberson]

You mentioned AverTV. AverTV is made by AverMedia, which has a number of different products; see https://www.avermedia.com/tv_more/#product

Ok I see. I have AverTV Hybrid Volar HX but there is not in the link so I used AverTV Hybrid Volar HD

The information I find at https://www.cnet.com/products/avermedia-avertv-hybrid-volar-hx-digital-analog-tv-tuner-radio-tuner-video-capture-adapter-usb-2-0/specs/ suggests that the Volar HX does not have a BNC connector. It appears to have an S-Video (mini-Din-4) and two RCA connectors.

Is it possible that you are using a BNC to RCA cable ?

[Flavie]

I think I have a BNC cable with a RCA connector.

Okay, I need to sleep now; it will be some time before I can look at this again. Perhaps someone else will have time to investigate.

Yes I need some help, could you help me please ? That would be really great

I am encountering significant doubts about applicable driver versions. The avermedia pages just do not have any information about the Volar HX A827 product, but the information about driver versions I find elsewhere hint that the A827 used the Driver:2.* series. The avermedia page for the Volar HD A835 suggests driver Driver:2.3.x.28 for that, but the third party sites are offering Driver:2.0.* or older, or at most Driver:2.1.* . Older versions of the driver for the A835 include Driver:8.* series -- why would you go for a lower number range for improvements? The drivers for new devices appear to be mostly Driver:10.* series.

There is a chance that the Driver:2.3.x.28 is the correct driver for the A827 in both 32 bit and 64 bit Windows, but I have no evidence that the Driver:2.3.* was ever supported for the A827 -- and the versions I do find listed for the A827, the Driver:2.0.* series, do not appear to have ever been the appropriate ones for the A835, leaving doubts about compatibility. I would be reluctant to load the driver off of the random sites I am finding it on.

The discussions about creating a Linux driver for the A827 did not get very far. Avermedia stopped supporting it some time ago, and has deleted all of the official drivers from their web site. Support for it was never better than partial.

I can see from the discussion that I can find, that any driver for it would not be "USB Serial" based.

My thought, based upon the information I have found (or not) is that getting this device to work with MATLAB's image system would be a "labour of love" -- that if you are not prepared to work on it over a period of a couple of years "for hack value" then I would advise you to give up on this device.

The more modern A835 (Volar HD) has better prospects, perhaps by hacking the Linux driver for it.

The information I find suggests that even with the newer devices, there is no API or ActiveX control offered by the company.
