我正在使用WebRTC和socket.视频通话的io.
通话正常，但当我运行"关闭摄像头"功能时，视频会停止，但网络摄像头的灯仍亮着.
以下是关闭摄像头的功能:
const mute= ()=>{
setMuteCamera(true)
navigator.mediaDevices
.getUserMedia({ video: false, audio: true })
.then((stream) => {
setStream(stream);
myVideo.current.srcObject = stream;
if (stream!= null) {
stream?.getTracks().forEach((track) => {
track.stop()
})
}
})
}每次你打navigator.mediaDevices.getUserMedia()，就会产生一个new MediaStream和new MediaStreamTracks.关闭这些新的MediaStreamTracks不会关闭以前的MediaStreamTracks.
So what you need is to keep track of your previous MediaStream, and close the VideoTrack from it.
Given your current code it seems that you do set it as myVideo.current.srcObject, if so, you can access it from there:
const muteVideoTrack = () => {
myVideo.current.srcObject.getVideoTracks().forEach((track) => track.stop());
};
Or you could also simply store this MediaStream in any variable accessible to your method.
This will let the MediaStream capture only the microphone. If you wanted to completely stop the whole MediaStream, then call getTracks() instead of getVideoTracks(), and optionally set the srcObject to null.
