No software method, just both cameras aimed at the same high-speed binary counter.

Re: Stereoscopic camera capture - now implemented.

Thanks, removing the errant -3d has got the modified raspistill working as intended. The modified raspivid only appears to be capturing from a single camera though, so I'm going over the code to check the diff applied correctly.
::EDIT:: Yup, diff misapplied.

Re: Stereoscopic camera capture - now implemented.

Please note that my diffs will NOT provide those command options. My diffs hard code the stereoscopic mode as I was just testing things. Adding them as options isn't difficult so had been left as an exercise for others whilst I had been looking at firmware issues - no one seems to have stepped up t...

Re: Stereoscopic camera capture - now implemented.

Even after cd'ing into the build directory, you will need to execute it with ./raspivid which is the correct path to the named file contained in the current directory. Equally, without cd'ing, you could have started it with bin/raspivid If you don't specify the full path explicitly, linux will look...

Re: Stereoscopic camera capture - now implemented.

I cloned git://github.com/raspberrypi/userland.git, modified the code, and used cmake and make to build it. I made sure I was in the /bin subdirectory to make sure I was using the newly built executables.
Not sure what the buildme script is (new to Linux), where would I find it?

Having some trouble getting this running. Cloned the git repo, applied the diff (had to remove the mmal_parameters_camera.h portion as that would not patch, and appears to have already been implemented as a v2?) and ran make.

Tolerance of camera board to other packages (and sensors)

Does the board (and the we-cant-see-the-source part of the GPU-side gubbins) do any sort of checking as to which sensor module is attached, or will it only work with the P5V04A? e.g: 1) Could an alternate camera module using the OV5647 ( for example ) work, assuming the connector pinout is the same?...

It will only work if your GPU can output a DP signal from a HDMI port, or (more common...

Re: Camera module! (And a picture of JamesH)

I was thinking more long the lines of disconnecting the camera module entirely from the MIPI interface, and just hooking up the I2C header (or directly to the pins with some fine wire, if the camera board doesn't have am appropriate header) directly to the Pi's on-board I2C. post processing of the i...

Re: Camera module! (And a picture of JamesH)

Point. Would it be easier (or even possible) to have anyone who wants more control fiddle with lens compensation and the like directly (by hooking the camera module up via I2C and flipping bits in the register) without any modifications to the driver? Can you even do that via I2C?

<t>A BD image is typically DRM free, as is the plain folder structure.

You either have a plain disc image or a image without any video data at all (or just an error m...

Re: HDTV Box

Standard VESA spacings (100mmx100mm) are quite a bit larger than the intended size of the RaspberryPi. You'd either need to find something else to cram into the case, or waste quite a bit of space.

Re: Raspberry Pi - the smallest gamestation ?

The RaspberriPi has a much gruntier ARM and GPU than the OpenPandora, and that can emulate the PSX, N64, and plenty of 16 bit and 8 bit consoles. The RPi shouldn't have any issues doing so as long as someone is willing to port the emulators over.
