| go4iqh1fu | hello
i have this pci card: http://microdream.co.uk/media/catalog/product/cache/1/image/512x512/9df78eab33525d08d6e5fb8d27136e95/p/i/picture_017_8.jpg how can i find out if i can use those 3 analog connectors (yellow, red, white) for video in or if they are only for video out? here i found a better picture: http://i.ebayimg.com/images/g/p~4AAOSwCypWmink/s-l1600.jpg my goal with this hardware: beeing able to connect an old analog output device to a linux pc and use the computer screen as a live video output | [20:01] |
| awalls | those are likely inputs.
that is a cx23416 based card. it may be supported by the ivtv driver. it looks like a conexant reference design card. of the ivtv cards the PVR-150 is the best to have, if you can still find one. conventional PCI slots are pretty rare on modern computers though. | [20:16] |
| go4iqh1fu | awalls: thanks for the answer. Followind drivers start to load: wm8775 and ivtv0. I would have to add the required firmware files. What software did i need after adding the firmware files to be able to simply stream those analog outputs to the monitor? | [20:19] |
| awalls | they are inputs, not outputs | [20:19] |
| go4iqh1fu | yes,i hoped they were inputs. i would like to connect to those an analog device. for example an old nintendo NES and play it on the screen | [20:20] |
| awalls | MPlayer works in a pinch
the ivtv driver will by default give you the MPEG compressed output on the first video device it has a 2 second lag that is no good for gaming there is another device node for uncompressed yuv output which is less lag | [20:21] |
| go4iqh1fu | btw: ivtv0 reports on 4.11 kernel: Unknown card: vendor/device: [4444:0016] , subsystem vendor/device [104d:816d], cx23416 based.
it tells me to report this to the developers | [20:23] |
| awalls | the yuv output is in a weird hm12 format that MPlayer knows how to handle
yeah, that card is some random unlabeled card, probably a Conexant demo/reference card. the driver doesn't know specific information about how chips are wired up on it you could force a card type when loading the driver module and try to find one that works modinfo ivtv for a list of card type numbers | [20:23] |
| go4iqh1fu | i can make detailed pictures of this card. i like helping to make the linux environment better :) | [20:27] |
| awalls | if that's the card with the weird Sony video decoder chip on it, forget it.
Sony never released information on that chip | [20:28] |
| go4iqh1fu | this lag is probably completely fine for watching video from analog output. i hope the 2sec lag is on video and audio side and synchronized | [20:29] |
| awalls | there's no information on how to program it. | [20:29] |
| go4iqh1fu | its the sony karin enx-25 | [20:29] |
| awalls | sorry, no linux support for that card will ever happen.
I asked Sony for the info years ago and they never provided it. | [20:30] |
| go4iqh1fu | you probably know it really good. so none of the chips on this card can be used by myself?
i seem to be talking with the correct person here :) | [20:30] |
| awalls | the video decoder chip is what converts analog video signals to digital
so, nothing useful with video can be done with that card. | [20:31] |
| go4iqh1fu | okay. that information helped a lot. thanks :)
maybe i can find somewhere some other analog card that could maybe be used i am also willing to donate this card on my cost to some developer in europe if that could help adding support for this card :) | [20:32] |
| awalls | just junk the card. Sony isn't ever going to provide the needed information.
try to find a pvr150 on ebay, if you must use conventional PCI | [20:36] |
| go4iqh1fu | i dont have to use pci. i can use probably everything :)
what device should i take for gaming? | [20:40] |
| awalls | ask in #v4l or on the linux-media mailing list | [20:43] |
| go4iqh1fu | thanks :) | [20:53] |
