Steps to Setup Proper Camera Streaming Environment on a Fresh SD Card

1. Run MainInstaller.sh as root (found in the installer directory).

2. Run AutobootSetup.sh as root (found in the installer directory).

3. Run "tvservice -d edid" from the terminal followed by "edidparser edid".

4. Find the preferred screen resolution / refresh rate from the list, look for HDMI:EDID DMT or CEA mode.

5. Open /boot/config.txt as root. Uncomment out hdmi_group and hdmi_mode. If the reolution was CEA, write a 1 for group, if it was DMT write 2 Write the number in brackets after the mode for hdmi_mode.

   i.e) if you see:

   HDMI:EDID best score mode is now DMT (27) 1280x800p @ 60 Hz with pixel clock 71 MHz (score 5184320)

   Then write 2 for hdmi_group and 27 for mode for a result of:

   # uncomment to force a specific HDMI mode (this will force VGA)
   hdmi_group=2
   hdmi_mode=27

6. Save the file and reboot the pi.

Compiling and Running the Program

1. After cloning the repository, navigate to the installer directory: cd Installer

2. Run the MainInstaller.sh script as root: sudo ./MainInstaller.sh

3. Generate the executable with make -j4, -j4 will decrease the compile time by using 4 threads, this number can be increased depending on how many threads are adequate

4. The program should now run with ./BackupCamera

   • The program currently takes 6 command line arguments: 2 for window position (x, y), 2 for window size (x, y) and 2 for camera resolution

   • For example try: ./BackupCamera 100 100 100 100 100 100
