在mediasoup-demo-3中开发FlexFEC的部分代码如下所示:
在服务端:
1. 在mediasoup-demo-3/server/config.js文件中的webrtc.router.rtpCapabilities对象中,添加FlexFEC的参数:
```javascript
rtpCapabilities: {
codecs: [
...
],
headerExtensions: [
...
{
kind: 'video',
uri: 'urn:ietf:params:rtp-hdrext:flexfec-03',
preferredId: 1
}
]
}
```
2. 在mediasoup-demo-3/server/lib/Room.js文件中,添加FlexFEC的支持:
```javascript
const router = await worker.createRouter({
mediaCodecs,
routerOptions: {
...,
// Enable FlexFEC
additionalSettings: {
'rtp.enableFlexFEC': true
}
}
});
```
在客户端:
1. 在mediasoup-demo-3/client/src/config.js文件中的webrtc.headerExtensions.video数组中,添加FlexFEC的参数:
```javascript
video: [
...,
{
uri: 'urn:ietf:params:rtp-hdrext:flexfec-03',
id: 1
}
]
```
2. 在mediasoup-demo-3/client/src/hooks/useMediaStreamTrack.js文件中,添加FlexFEC的支持:
```javascript
async function getVideoConstraints(track, device, peerCapabilities) {
const constraints = {
deviceId: { exact: device.deviceId },
width: { ideal: 1280 },
height: { ideal: 720 },
frameRate: { ideal: 30 },
advanced: [
{
// Enable FlexFEC
// Note: This assumes that the FlexFEC extension URI is 1
// and the parameters are the default values.
fec: {
mechanism: 'flexfec-03',
ssrc: track.ssrc,
repairWindow: 10,
maxPacketLost: 5,
maxBitrate: 1000000
}
}
]
};
return constraints;
}
```
这些代码片段展示了如何在mediasoup-demo-3中开发FlexFEC的部分代码。请注意,这些代码只是示例,并且在实际使用中可能需要进行修改和调整。
