is is possible by using a RCA Video to 3.5mm audio jack connected to line-in on my computer to get the video on my computer?
Is there some program out there to decode the video signal from the audio??
If you know anything PLEASE reply, telling me to buy a video-in card DONT reply, it's not for saving money just a project i have started!!
The jack you are referring to is not an audio jack, there is a special RCA 3.5mm jack that has four connectors. But, you can never import video throuh a sound card. You need a capture card (sorry, had to say it...)
He said it, there is a special jack for it, and the jist of the matter is is that audio data and video data are 2 totally different theings. Its like expecting to get sprite from a carton of orange juice, it just wont happen uless you can overwrite software and alot of bios, and even then it still might not work depending on hwo your computer handels the data processes it and then simply exports it out fo the jack.
The other guys are right: it is not possible. Why? To put it simple: bandwidth.
Bandwidth of the sound cards is 20 kHz or less. You will never capture a 6,5 MHz signal with it.
Are you talking about the white and red audio cables used in dvd players and playstations etc.
If you are then yes. I even have an adaptor that came with my ATI tv card.
