Play Video Content from Raspberry Pi

To begin, navigate to the base directory of the DLPDLCR230NPEVM python scripts and initialize the parallel video mode. Assuming that the python scripts have been loaded to:

/home/pi/Documents/dlp

Execute:

$ cd /home/pi/Documents/dlp

$ python3 init_parallel_mode.py

From here, display of any video content or images from the Raspberry Pi is possible. For example, at:

/home/pi/Documents/dlp/media

Navigate to the desired directory. It is recommended to use the list command to see what content is available:

$ ls -l

This folder is empty by default. To display video content, simply execute the following command (replace the file name with the desired video file):

$ omxplayer <filename>.mp4

The video will play in a letterbox by default. To stretch the video to play in fullscreen (regardless of the resolution) use the following command instead:

$ omxplayer --aspect-mode stretch <filename>.mp4

Press CTRL+C to exit the video playback.
