如何通过 访问深度流轨道的属性getUserMedia()
?我试图获得的属性principalPointX, principalPointY, focalLengthX, focalLengthY
来自媒体轨道
文档说我需要设置depth
为 true,所以当我这样做时,我收到一个错误,迫使我设置 a video
:
(index):20 Uncaught TypeError: Failed to execute 'getUserMedia' on 'Navigator': At least one of audio and video must be requested
当我尝试这样做时:
navigator.mediaDevices.getUserMedia({video: true, depth: true})
.then(stream => {
video.srcObject = stream;
console.log(stream);
}).catch(console.error)
stream
不会返回我想要获得的任何属性principalPointX
。任何帮助,将不胜感激。
