Raw Frame Recording
In some cases one might want to check that a Cell is working as expected. For this purpose there is a possibility to record the video stream from the camera directly to the computer hard-disk. This raw frame data can then be analyzed to identify and fix issues with the Cell hardware and tracking algorithms.
The process for recording the video stream is as follows:
- Launch ViewBasic
- Press the 'f' key once. This will start recording data (you should see dots ... appearing in the console)
- Wait for 4 seconds and then put you hand on the display
- Move your hand around the touch-screen (try to cover the entire screen area, including areas that both work and don't work).
- Once you've have done this (around 15 seconds should be enough) press 'f' again to stop the recording.
- Exit ViewBasic
- In the directory from where you launched ViewBasic you should now have a directory called 'raw-frames-XXXX...' with lots of
.TGAimages inside it.
To transfer the image data, you will need to compress the directory, using some compression utility, such as zip, 7-zip, tar, or other tools.
For example on Linux/OS X, you can run the following on the command line:
tar cvfz frames.tgz <raw-frames> (press enter)
To deliver the frame data, it is easiest to upload it to some web server, or use some on-line data exchange services (yousendit etc.).
If sending the frame data to MultiTouch for analysis, you should include your config.txt file, so that we can identify any issues related to the configuration.
