STATUS: PERPETUAL DEVELOPMENT
CURRENT KNOWN MAJOR ISSUES:
Videos with and audio track (even silent) work best and allow more accurate looping/frame tracking

DESCRIPTION:
This is an openFrameworks video player addon for the Raspberry Pi. The video player is hardware accelerated and can provide textures to openFrameworks to be used for shaders, etc.

REQUIREMENTS:
GPU split set to 128 (may need to be higher for larger videos) openFrameworks version 0.8 or higher http://www.openframeworks.cc/setup/raspberrypi/

USAGE:
(NEW) Clone into openFrameworks/addons

There 2 modes of Playback, textured or non-textured.

Non-Textured:

  • By default is played fullscreen video
  • OF is still able to run other processes in the background.
  • 1080p video playback is typically good

Textured:
Allows the use of

  • shaders
  • pixel access
  • drawing overlays
  • 720p video works best here

Audio:

  • Audio can be played back through HDMI or headphone jack
  • May be disabled to save resources
  • initialVolume can be passed

Headphone jack may require this tweak:

To use HDMI Audio you may need to add the below line to /boot/config.txt and reboot. See http://elinux.org/RPiconfig for more details

hdmi_drive=2

EXAMPLES:
example-basic:
Playback of video in texture mode (default)

example-multiple-players:
Simultaneous playback 2 videos in non-texture mode

example-playlist:
Playback of a folder of videos in texture mode

example-pixels:
Example of pixel access that is needed for OpenCv operations/Saving images, etc

example-restartMovie:
restart a movie by pressing "r" + ENTER in ssh session (or "r" on attached keyboard)

example-shader:
Use of shaders, fbos and video

example-multiple-players:
EXPERIMENTAL: shows some of the more "alpha" features

  • Multiple players
  • Usage of a display area to play non-textured video non-fullscreen

COMPRESSION RECOMMENDATIONS:

TODO:

  • Implement better Seeking
  • General cleanup (many properties are public)
  • Possibly have it extend ofBaseVideoPlayer
