AR.Drone live onboard video – “height record”

Trying to reach new heights with the AR.Drone out in a field. It does go quite high for a toy quadricopter if you ask me. Flight was reasonably stable but the controls were not very responsive.

The video was shot with Display Recorder, but at the end a lot of frames have been skipped. This video had the following settings: Rotation: Landscape Left, Video Quality: Medium, OpenGL capture: On, Grayscale: Off (obvious), Framerate: 20fps and Lock Framerate: On. I will try to play with the settings and see whether I can improve the quality of the next video. If you have better quality please leave your settings in the comments. Perhaps the lack of responsiveness of the controls is related to Display Recorder.

AR.Drone video recording from onboard cameras test video

Unfortunately it was already dark yesterday when I wrote my previous blog post about how you can use Display Recorder to record the AR.Drone video streams from the onboard cameras. So I had to wait to shoot a demo video. But without further ado I present you the recording of my first emergency landing. (And yes I know, you probably should not fly near those overhead electricity conductors and pylons).

Recording live AR.Drone video with Display Recorder (Cydia)

One of the features that is missing from the FreeFlight software is the ability to take pictures or record the video stream from one of the two onboard cameras. This drone thing was supposed to bring Big Brother surveillance capabilities to the masses, wasn’t it? The video stream for the front and bottom camera is displayed on the iPhone screen but there is no way you can record it. Not unless you jailbreak your iPhone and install Display Recorder by Ryan Petrich ($4.99 in the Cydia store).

With Display Recorder installed you can record everything that is displayed on your iPhone screen. Once installed you start it by pressing the sleep button for 1 second. Display Record will ask you if you want to start recording. It will then record everything to an AVI-file until you press the sleep button again. After recording you can upload the video directly to YouTube from your phone or download the files to your computer through a integrated webserver that you can turn on in Display Recorder.

If you want to record the video from the cameras on the AR.Drone you will have to change Rotation to Landscape Left or Landscape Right in the Display Recorder setting. Display Recorder settings can be found as an option in Settings on your iOS device. Other things you probably want to change are to not Show Taps and perhaps use a higher Video Quality.
