Depreciation notice

41 | 42 |

43 | This was intended for auto-playing videos on iOS, but as of iOS 10, there is native supported option playsinline, read more here: 44 | 45 | https://webkit.org/blog/6784/new-video-policies-for-ios/ 46 | 47 | (Android works for ages now). 48 |

49 |

50 | So this project is not actively maintained anymore. Use native HTML video instead of it. 51 |

52 |

53 | If anyone wants to take over the maintenance, feel free to open an issue, and I'll add you as contributor. 54 |

HTML canvas video player

58 |

Easy way to play videos inline on iPhones

59 |

60 | This is intended for iPhone only, it can be used on any other browser 61 | which support canvas and video. It doesn't play sound, I have no real 62 | plan of adding audio support. 63 |

64 |

65 | Audio is now supported. Autoplay on iOS is NOT working with 66 | audio (autoplay is disabled in that case). 67 |

68 |

69 | It can be used with any HTML video player, just position canvas over the video. 70 | Intended usage was for background videos and showcases. 71 | Still, if you can, use regular HTML5 video, this was intended to use only on iPhones. 72 | This is plain JavaScript solution, no dependencies, IE9+ and modern browsers. 73 |

74 | 75 |

76 | For IE9 there must be requestAnimationFrame polyfill. 77 | Audio is not tested on IE9. 78 |

79 | 80 |

81 | Please let me know if you are using this player, I would like to make a small showcase, thanks! 82 |

Minimum setup:

99 | 
100 | var canvasVideo = new CanvasVideoPlayer({
101 |     videoSelector: '.js-video',
102 |     canvasSelector: '.js-canvas'
103 | });
104 |
105 | 106 |

Aditional options:

107 | 
108 | var canvasVideo = new CanvasVideoPlayer({
109 |     videoSelector: '.js-video',
110 |     canvasSelector: '.js-canvas',
111 |     timelineSelector: '.js-timeline',
112 |     framesPerSecond: 25,
113 |     hideVideo: true, // should script hide the video element
114 |     autoplay: false,
115 |     // IMPORTANT On iOS can't be used together with autoplay, autoplay will be disabled
116 |     audio: false, // can be true/false (it will use video file for audio), or selector for a separate audio file
117 |     resetOnLastFrame: true, // should video reset back to the first frame after it finishes playing
118 | 		loop: false
119 | });
120 |
121 | 122 |

Methods:

123 | 
124 | // Unbinds all of the events (when you destroy the player)
125 | canvasVideo.unbind()
126 | 
127 | // Plays video
128 | canvasVideo.play()
129 | 
130 | // Pauses video
131 | canvasVideo.pause()
132 | 
133 | // Plays video if paused and vice versa
134 | canvasVideo.playPause()
135 | 
136 | // Draws current frame on canvas, should not be called manually
137 | canvasVideo.drawFrame()
138 |
139 | 140 |

Detecting iPhone:

141 | 
142 | var isIphone = navigator.userAgent.indexOf('iPhone') >= 0;
143 | // Other way to detect iOS
144 | // var isIOS = /iPad|iPhone|iPod/.test(navigator.platform);
145 | 
146 | if (isIphone) {
147 |     // Init CanvasVideoPlayer here
148 |     new CanvasVideoPlayer({
149 |         // Options
150 |     });
151 | }
152 | else {
153 |     // Use HTML5 video
154 | }
