Ah, OK, we are talking at cross purposes. You camera is already doing all the hard work, and doesn't use the same camera interface available on the Raspberry Pi. I have no idea how you would connect a camera like that, having looked briefly at the data sheet, I don't think it's possible without extra hardware,Hardware_man wrote:The camera that I want to use is a Sony FCB-EH3150. It is a camera module, more than just the CCD. HD outputs in Analog component or digital LVDS.
I think a lot of the "tuning" is already done in the camera.
I want to use the Pi board to run a high profile H.264 encoder to get data rates down to the write speed of the SD card for a high end DVR implementation.
Does this simplify the process?
Yes, it would need custom GPU code (if it's even possible), so either done by Broadcom or the Foundation (who have access to the code).ghans wrote:But this would still need custom debugged GPU code to work ,
and without this it won't work at all, or am i mistaken ? So this
needs definitely involvment of Broadcom employees.
Done as a project using the VC4 but not involving Raspberry PI. Not sure whether its hit the market yet (or if it ever will!). Not to say it wouldn't be possible on the Pi though, but the main issue is HDMI in needs all sorts of nasty DRM.EdZ wrote:Is this a "we've done it with some other board, so it's theoretically possible", or a "we have a HDMI-in driver in the works for the 'Pi"?We've done something similar with HDMI in - converted the HDMI to CSi-2.
It does sound feasible. It would require a new driver on the GPU, but the pass through needed (no need for the ISP) is in place. I'll have a chat with the guy who did the HDMI version and see what he thinks - that'll be Monday at the earliest.Hardware_man wrote:Jamesh,
This was my thought. I do an analog component video to CSI-2 adapter / converter board. You grab the CSI-2 data and make several H.264 encoding algorithms available (high quality / not much SD card record time to low quality / lots of SD card record time). Put the SD card video file into a container file like AVI or WMP and play the SD card on any computer.
Like I said, then the Pi becomes a "plug and play" DVR for any video in analog component format. I'm certain at that point, somebody will expand it so you could record hours on a USB hard drive.
What do you think?
