ofxDSHapVideoPlayer

ofxDSHapVideoPlayer is a video player addon for openFrameworks. It plays Hap-encoded videos natively on Windows using Direct Show video playback tools.

Hap is a video codec that is decoded on the GPU. Some of its benefits include fast decompression and low CPU usage. It was written by Tom Butterworth for VidVox/VDMX. For further information on Hap, see http://vdmx.vidvox.net/blog/hap.

Requirements

Before encoding videos using Hap codec, install the Hap codec for Direct Show. An installer is available from http://www.renderheads.com/downloads/2015/HapDirectShowCodecSetup.exe

Usage

In ofApp.h

ofxDSHapVideoPlayer videoPlayer;

In ofApp.cpp

void ofApp::setup(){

	videoPlayer.load("HapVideo.avi");
	videoPlayer.play();
}

void ofApp::update(){

	videoPlayer.update();
}

void ofApp::draw(){

	ofSetColor(255);
	videoPlayer.draw(0, 0);
}

Notes

• ofxDSHapVideoPlayer plays back Hap videos in .avi containers. It will not play back Hap-encoded video files in QuickTime movie containers. Encode Windows .avi files using Adobe Media Encoder, After Effects or other.

• Sample Hap video files are available on http://renderheads.com/product/hap-for-directshow/

• ofxDSHapVideoPlayer now supports snappy compression, but the performance is not as snappy.

• This addon works with openFrameworks 0.9.0. For 0.8.4, use release 1.0.0 (https://github.com/secondstory/ofxDSHapVideoPlayer/releases/tag/v1.0.0)
