    Hi,

    just wondering if its possible to make Hyperion support HDMI grabbers? I have no clue about Linux and raspberry, so please dont hate me if I am talking nonsense :D

    But I think this way we could use a digital image with 100% correct colors and the right aspect ratio (I am using a 21:9 screen for example)
    No need anymore for the converter box. Just the splitter is necessary.

    I would be willing to buy one and leave it to the developers until support is implementet (if possible at all)

    hdmi grabbers (legal ones) use hdcp for the signal, if you dont have a license for it, you cant use it :) there is no option for now...sorry :)

    True.. didnt think about hdcp on this one.
    But the splitter disables hdcp anyway, right? So this is more a problem with the laws, not a technically one? Just curious.

    You can use any in linux supported v4l devices with hyperion. If you have an hdmi grabber with linux support it will work with hyperion.
    As pointed out hdcp will be a problem - but there are splitters that solved that prob.

    Btw. You can you use a webcam as input. Its very funny.

    Are you sure about _any_ v4l grabber?
    I tried (briefly) to get my hauppauge hdpvr to work and it wouldn't capture

    did you remove the hdcp with a splitter?

    its capturing from composite/component but /dev/video0 gives you an mpeg4 file

    ya I found out it would work this way without any coding needed. However, only found 1080p grabbers so I decided not to buy one.
