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:
- Use MPEGStreamclip (http://www.squared5.com/)
- H.264
- Quality 50%
- PCM Audio (more compatible with HDMI)
TODO:
- Implement better Seeking
- General cleanup (many properties are public)
- Possibly have it extend ofBaseVideoPlayer
