Re: New raspividyuv app

This diff fixes the issue and makes -save-pts work as expected. Caveats: The output file for timestamps is not exactly the same as for raspivid. A buffer timestamp of MMAL_TIME_UNKNOWN is silently dropped in raspivid, and here it is output as a separate line. Also the timestamps are output as-is and...

Re: New raspividyuv app

I'm having slight problems with raspividyuv. The -save-pts option just creates a file with a single comment line and no timestamps. I've also tried the newest compiled version from the repository with the same results. The same option works for raspivid and outputs timestamps in ms as expected. Conc...

Two cameras + I2C?

I was just trying to connect an I2C device (servo controller) in addition to my two cameras but noted that the necessary camera pin connections occupy both I2C-0 and I2C-1 SDA/SCL connections (default settings). Strangely while dt-blob.bin is active and without settings i2c=arm I am not able to quer...

USB slave connector as USB host using OTG cable?

C.f. the Compute Module evaluation board... Is it possible to attach an USB peripheral device (e.g. WLAN card, keyboard, ...) by attaching an OTG cable to the USB slave port? I've read somewhere that the USB controller can switch between USB A connector and the slave port but can it 1) connect both ...

Re: Kinect - Would it ever work with a Raspberry Pi?

I'm using the Kinect-for-Windows which outputs 1280x960 color images (@ 12fps), and AFAIK (did not test yet) the Kinect-for-XBOX can output up to 1280x720 color images (@ 15 fps). It's true that depth information is available at most 640x480 @ 30fps (where not every pixel is sampled at every frame, ...

Re: Kinect - Would it ever work with a Raspberry Pi?

Hi all, I am currently working on a commercial project involving the Kinect without skeleton tracking... so the RPi only needs to capture depth and image frames, at reasonable rates (about 4fps) and store them on the SD card as raw frames. I've installed OpenKinect / libfreenect from the git tree an...
