Of course it's possible (I've seen it done). I think its Toshiba who do a HDMI to CSI convertor chip which would be easier to do than the scheme I have seen.rkinch wrote:But HDMI-in itself is not possible. That's why there are never HDMI inputs on video recorders.jamesh wrote:That's only really possible with HDMI in.
The difficulty arises when the incoming datastream is encrypted, when you would need HDCP keys in the convertor chip. I think Toshiba make two variants of the chip, one with encryption ability, one without. I'm presuming HDMI to the Raspi would not support encrypted datastreams.
