"self" made HD video camera

Recommended Posts

Hi,

Anyone has attempted to make their own HD camera using for example, a HD webcam + a gumstix overo ?

Or a leopardboard + a 5Mp camera ?

I'm interested in the video quality results (i'm not sure the overo can compress HD due to the small OMAP3530)

Probably Kilrah especially know about this (?)

Thanks

I looked into this, but it's pretty much a dead end from a hobbyist point of view for now.

HD is way too much for a Gumstix. It would take some VERY beefy SOC, like the high end chips from TI, and a LOT of development as these are far from easy to implement both from a hardware and software point of view.

There are easier ways, using the same chipset that is used in most small consumer HD cams (Toshiba S10, Sony Webbie/Bloggie, GoPro et al), which is specifically developed for that, and that's mostly "plug and play". BUT, the manufacturer, Ambarella, won't even talk to you, so even less supply you with comprehensive documentation, samples or a development kit if you're not a big company intending to produce some million of pieces...

Yes I know about Ambarella, their chipsets are actually better for video, but it's not possible to get anything from them.

Some faster TI chips seems to give decent quality on smartphones although no 1080 yet.

The BeagleBoard XM has a pretty "beefy" SOC even if the card is a bit big, it's rumored to achieve nearly 1080p25. It's on preorder so far.

The LeopardBoards are just slightly faster than the Gumstix but apparently allow 720p30. I'm unaware of the bitrate however...

What would be interesting is getting our hands on a Ambarella SDK unofficially or have someone who has it :P

I'm pretty sure we can boot those Camileos and friends and modify them (well at least the ones with the A5, I'm not sure if the A2 runs linux). (no DMCA in my country)

Actually, in theory we should be able to force them to release the source code parts that is GPL which already gives a lot of hints, but I'm sure they'll refuse without a trial.
