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

``c++ 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)
