Analog video input?

Hi Jano,

Welcome to the element14 Community!

So that we can better help you get the answer you’re looking for, can you let us know what device you are working with.

Thanks,

Jason G.

I am talking about Raspberry Pi device, sorry.

In documentation is information about HDMI port that it is output only. I did not find if composite port is both way or not.

Thanks

Hi Jano,

No worries. I don't think so but I do not really know for sure.  So what I am going to do is move this question over to the Raspberry Pi Group. Someone in this group should know for sure.

Sorry I couldn't help out more!

The RasPi HDMI and Composite video jacks are output-only.

For video input, I suggest that you go to raspberrypi.org and enter "Video Input" in the Google search box on the front page.  There is a CSI digital camera header and RasPi is working on a camera module, which I just learned will have composite video input: see this thread chez RasPi: http://www.raspberrypi.org/phpBB3/viewtopic.php?f=63&t=20159

There may also be USB video capture devices -- the "Video Input" search should tell you what (if anything) works.

Hi John,

I think the camera module won't have any analog input (I looked at that thread recently). There was another thread

where someone offered to made a digital input hardware (HDMI I recall) but I think that went nowhere either.

So, I think no video input is planned to be offered on Rasp-Pi, just image or video from the actual camera board.

USB capture devices may be the easiest solution for now, if drivers can be compiled for it.

The unfortunate downside (or I suppose fortunately in some scenarios) is that USB capture devices compress the data.

If your problem is finding a way to send the video to the Pi, you probably need somthing like this: http://www.amazon.com/EasyCAP-DC60-Creator-Capture-High-quality/dp/B002H3BSCM

As for the software to use with it... I guess a throrough search on Google for Linux apps that can fetch analog input from the USB could do the trick.

USB device looks fine but I am afraid about drivers and implementation.

Idea is to use RPi as video streeming device from analog to digital streem. I saw some ELEC XBMC advert to do it but it maybe generic for other platforms or devices.

VLC should do it too.

I read thread referenced by johnbeetem and looks like chance to have analog input on RPi is small. I must wait for somebody who try implement USB device as video input. :-)

Thanks to all of you

I know this thread is almost a year old but for anyone still considering using an Easycap USB device to encode analogue video there is some useful advice on which versions are compatible with linux here:

Easycap - LinuxTVWiki

Hope it helps.

Yes this stuff has been supported by standard Linux for years so there is no reason why not and if there's a problem it shouldn't be too bad to pull that driver and build it your self presuming another 50 folk haven't already done it

Good luck with your project...John
