Re: USB packet loss.

No, I'm not going to expand. I made my point very clear. If you don't want to understand, that's your problem. USB working properly is not an unreasonable expectation, the SD driver not slowing down the pi to a halt is not an unreasonable expectation, and so on. But please let's stop polluting this ...

Re: Autofocus

I'd say all they're doing is focusing at the hyperfocal distance . The postprocessing looks like just some regular (over)sharpening. You can't really recover the lost information from a blurred image. (edit) ok I was mistaken, the thing is they use a special lens: EDoF stands for Extended Depth of F...

It should have worked perfectly, if it was expected not to work properly nobody at the foundation would be trying to fix the issues it has. Not at all true.

Re: USB packet loss.

There is a reason why the pi costs $35 and a quad core Intel processor costs $350 or more... People's expectations are absolutely not absurd. The reason de Pi costs $35 is because it's non-profit. Not because it's kind of expected to be crippled. It should have worked perfectly, if it was expected ...

Re: gstreamer openmax

In that case I wonder if the transfer rate from the webcam in H264 mode is too much for the USB? The artifacts are present even when capturing at a low resolution with a low framerate On the contrary, h264 data is compressed and the amount of data will be much less than using yuv directly (or even ...

Re: 720p from USB camera + hardware h.264

It should be possible, in theory. But I'm having frames dropped and lock-ups at much lower resolutions so I'd say the pi's USB is screwed up (I'm also having half the packets dropped in a usb wifi adapter). So the correct answer is actually "no way in hell". (see http://www.raspberrypi.org/phpBB3/vi...

[offtopic] just look at the pastebin. You'd waste 10-15mA with the circuit I posted, with 0-1.5mA going through the LED. Perfectly usable to keep an eye on voltage (not voltage spikes of course).[/offtopic]
