When you run the program, video recording time was selected and checked if there is an internet connection. If the test is positive the video is constructed and transmitted via text/html 2022-09-20T00:08:44+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki2.arcoslab.org/dokuwiki/doku.php?id=teaching:ie0117:proyectos:2012:i:final_2013:camberry_final:intro&rev=1663632524&do=diff Introduction The project involves using a Raspberry Pi computer board to record video with a webcam and then back it up automatically on a remote FTP server with an Internet connection, at the time that such a connection is available. It is intended that the video file has a unique extension defined and remains constant as it extends the recording, eliminating sections of the oldest parts of the video as the system add the latest at the final of the video. text/html 2022-09-20T00:08:44+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki2.arcoslab.org/dokuwiki/doku.php?id=teaching:ie0117:proyectos:2012:i:final_2013:camberry_final:object&rev=1663632524&do=diff Objectives General objective Implement a digital video recorder kind dash cam with a Raspberry Pi and a web cam. Specific objectives * Install and configure Raspbian OS on a Raspberry Pi. * Install and configure the mpeg libraries and packages required (Stremer, FFmpeg) for recording video from a webcam. text/html 2022-09-20T00:08:44+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki2.arcoslab.org/dokuwiki/doku.php?id=teaching:ie0117:proyectos:2012:i:final_2013:camberry_final:res&rev=1663632524&do=diff Results The complete system in operation with the Raspberry Pi and the camera is shown in the following image. To run the program you must place the three files in one folder and with them create a folder called “video”, which will store all necessary temporary files.
