视频通话,本地视频正常,远程视频只有声音没有图像

1、获取远程用户成功,然后订阅远程用户音频和视频

async function subscribe(user, mediaType) {

const uid = user.uid;

// subscribe to a remote user

await client.subscribe(user, mediaType);

console.log("subscribe success");

if (mediaType === "video") {

if ($(`#player-${uid}`).length) {

return

}

const player = $(`

uid: ${uid}

`);

$("#remote-playerlist").append(player);

user.videoTrack.play(`player - ${ uid }`);

}

if (mediaType === "audio") {

user.audioTrack.play();

}

}

2、html代码

id为local-player的div

id为remote-playerlist的div

我是参考官方的demo,第一个生成本地视频流正常,第二个div生成远程视频流时,只有声音但没有图像,本人小白,还请各位指点
