js 打开摄像头方法 (定制摄像头)

时间:2021-10-30 10:50:38

var video = document.getElementById("video");
if (navigator.mediaDevices && navigator.mediaDevices.getUserMedia) {
    navigator.mediaDevices.getUserMedia({
        video: true,
        audio: true
    }).then(function(stream) {
        console.log(stream);
        mediaStreamTrack = typeof stream.stop === 'function' ? stream : stream.getTracks()[1];
    video.src = (window.URL || window.webkitURL).createObjectURL(stream);
        video.play();
    }).catch(function(err) {
        console.log(err);
})
}

  

第二种

//媒体对象
window.navigator.getMedia = window.navigator.getUserMedia ||
window.navigator.webkitGetUserMedia ||
window.navigator.mozGetUserMedia ||
window.navigator.msGetUserMedia;
window.navigator.getMedia({
video: true, //使用摄像头对象
audio: false //不适用音频
}, function(strem){
console.log(strem);
video.src = vendorUrl.createObjectURL(strem);
video.play(); }, function(error) {
console.log(error);
});
