At the start of data flow an ack will try to be sent and the remote port of the server will be undefined here: https://github.com/shinyoshiaki/werift-webrtc/blob/develop/packages/sctp/src/sctp.ts#L1111

Probably related to: #141, to make this work I had to "hack" the answer sdp to change "sctpmap" to "sctpMap".

FireFox DTLS issue

I can't recall if I ever tested Firefox before, so I'm unsure if this is a regression in Werift or behavior change in Firefox.

When attempting to connect a peer connection with a Firefox browser, werift fails during dtls handshaking with:
' ContentType.alert [object Object] BadCertificate flight 5 lastFlight [object Object]'

I'll see if I can fix this, but figured I'd give you a heads up first in case you know what the issue is.

Typo: onRecieve

https://github.com/shinyoshiaki/rainy-webrtc/blob/master/src/rtc/transport/sctp.ts#L43

trickle candidates

From what I'm observing, the stun/srflx are not trickled? It seems to hang/timeout the initial create/setLocalDescription if the stun server does not respond in a timely fashion.

How to use MediaStream ？

hi :
I saw that the API can use MediaStream addTrack, I want to combine them to get a stream of audio and video，Can you do an example? I tried to do it myself, but it didn't work
exp:

"throw new Error();"

Some data channel messages seem to cause werift to "throw new Error();" at this line: https://github.com/shinyoshiaki/werift-webrtc/blob/develop/packages/webrtc/src/transport/sctp.ts#L94

Here is the full log:

[ICE] re implementation TURN

Whether it can transfer the raw stream to the Web side

Get the original stream through ffmpeg and add it to the channel for Web-based presentation

I saw the ffmpeg example, which specifies the encoding format, but I need the browser to negotiate the encoding format with it

exp:

    const video= ffmpeg('/dev/video0')
        .size(`480x240`)
        .outputOptions(['-pix_fmt yuv420p'])

    const audio = ffmpeg("plughw:1,0")
        .inputFormat("alsa")
        .audioChannels(1)
        .audioFrequency(48000)
        .audioCodec("pcm_s16le")
        .outputFormat("s16le")

        .format("rawvideo")

useSdesMid causes negotiation with Google Camera to fail

This change introduced a bug in the scrypted google camera plugin.
This likely isn't a bug in werift. removing the extensions allows the webrtc connection to negotiate successfully (google returns 500 error otherwise).

f934e1a#diff-3bc78b20b7ffa3340be89f975e4457f6b8a11a11f67789d5554286e6ab0780caR1549

What are your thoughts on using conservative defaults to prevent issues like this? There are probably various sdp/webrtc consumers out there that will choke on unexpected data.

Here is my workaround in my code:

  const ret = new RTCPeerConnection({
          bundlePolicy: setup.configuration?.bundlePolicy as BundlePolicy,
          codecs: {
              audio: [
                  ...requiredAudioCodecs,
              ],
              video: [
                  requiredVideoCodec,
              ],
          },
          iceServers: getWeriftIceServers(setup.configuration),
      });

      ret.config.headerExtensions = {
          video: [],
          audio: [],
      };

MediaDescription defines property "sctpMap" but when setting a description looks for "sctpmap"

When setting a remote description, we look for the "sctpmap" property:

https://github.com/shinyoshiaki/werift-webrtc/blob/develop/packages/webrtc/src/sdp.ts#L223

But the property on the MediaDescription type is named "sctpMap":

https://github.com/shinyoshiaki/werift-webrtc/blob/develop/packages/webrtc/src/sdp.ts#L356

So if you try to set a remote SDP like so:

[TODO] Add max-bundle e2e test

TypeError: Cannot read property 'rtp' of undefined on `setRemoteDescription`

I'm currently trying to make a weird media server thing as a little experiment, though I keep getting the following error on setRemoteDescription:

    at RTCPeerConnection.remoteRtp (/home/MYUSERNAME/code/JS/project/chat/chat/node_modules/werift/lib/webrtc/src/peerConnection.js:382:26)

    at async WebSocket.<anonymous> (/home/MYUSERNAME/code/JS/project/chat/chat/api/v2/gateway/index.js:169:37)

Here is the serverside handler for getting an offer from the client.

let isNewConnection = true;
if (ws.rtc) {
    isNewConnection = false;
} else {
    ws.rtc = new GatewayRTCConnection(ws, this);
}

if (isNewConnection) {
    ws.rtc.connection.onTransceiver.subscribe(async (transceiver) => {
        const [track] = await transceiver.onTrack.asPromise();
        this.inChannel(channel._id, (otherWs) => {
            if (!this.clientRTCReady(otherWs)) return;
            if (otherWs.session.sessionId === ws.session.sessionId) return; // Don't perform the actions below on ourselves

            otherWs.rtc.addTrack(track);
            otherWs.rtc.renegotiate();
        });
    });
}

ws.send(this.packet("EVENT_VOICE_CONNECTION_ANSWER", {
    answer: await ws.rtc.answer(offer)
}));

if (isNewConnection) {
    this.inChannel(channel._id, (otherWs) => {
        if (!this.clientRTCReady(otherWs)) return;
        if (otherWs.session.sessionId === ws.session.sessionId) return; // Don't perform the actions below on ourselves
        
        const otherReceivers = otherWs.rtc.connection.getReceivers();
        for (let i = 0; i < otherReceivers.length; i++) {
            const otherRecevier = otherReceivers[i];
            ws.rtc.addTrack(otherRecevier.tracks[0]);
        }
    });
    ws.rtc.renegotiate();
}

This is the small GatewayRTCConnection wrapper I made to simplify the code a little:

class GatewayRTCConnection {
    constructor(ws, server) {
        this.ws = ws;
        this.server = server;

        this.connection = new werift.RTCPeerConnection();
        this.connection.onnegotiationneeded.subscribe(() => this.renegotiate);
    }

    async answer(offer) {
        await this.connection.setRemoteDescription(offer);
        await this.connection.setLocalDescription(await this.connection.createAnswer());
        return this.connection.localDescription;
    }

    async addTrack(track) {
        if (!track) return;
        this.connection.addTrack(track);
    }

    async renegotiate() {
        this.ws.send(this.server.packet("EVENT_RENEGOTIATE_REQUIRED", {}));
    }
}

I inspected it a little and found that one of the transceivers just does not have an mLineIndex, which is used in remoteRtp. I assume it's because I'm adding tracks myself to the connection, but I'm not sure what to do.
Note that it works fine with 2 users, as soon as the new user tries to connect, it generates this error.

[WEBM] Todo fix unknownsize Cluster

Probably the cause of the mkvalidator error

Can't work in Raspi debian 64

And we still can't figure out what caused it，Can you give me a hint?

Handling of `remoteIsLite` seems incorrect

iceControlling is set to true in setLocalDescription here if this.iceTransport.connection.remoteIsLite is true
iceControlling is set to true in setRemoteDescription here if media.iceParams?.iceLite is true

The problem is that remoteIsLite seems not to be set in the second case. This means that we end up with no controlling agent if we first setRemoteDescription and then setLocalDescription.

Maybe it is enough to set remoteIsLite = true in the second case?

Sending RTP packets from nodejs client to browser does not work

Hi!

I'm trying to send RTP packets from NodeJS client using werift-webrtc, to browser client using browser webrtc API. My code is basically the same as in sendonly example, the only difference is I spawn ffmpeg process instead of gstreamer.

I was testing the code with Brave (chromium), Firefox and Edge and for none of them sending video worked. I also checked webrtc-internal page and in statistics I noticed that RTP packets were received and all of them were lost.

Sending video worked, when the other client was another NodeJS client and not a browser one.

What do I need to do to send video to browser? Or maybe is it not possible at the moment?

Audio Data but no Video Data

Version: 0.14.2-debug2b
Node: v16.13.1

The following code:

const pc = new RTCPeerConnection({
        codecs: {
            audio: [
                new RTCRtpCodecParameters({
                    mimeType: "audio/opus",
                    clockRate: 48000,
                    channels: 2,
                })
            ],
            video: [
                new RTCRtpCodecParameters({
                    mimeType: "video/VP8",
                    clockRate: 90000,
                    rtcpFeedback: [
                        { type: "ccm", parameter: "fir" },
                        { type: "nack" },
                        { type: "nack", parameter: "pli" },
                        { type: "goog-remb" },
                    ],
                })
            ],
        }
    });

    const audioTransceiver = pc.addTransceiver("audio", {direction: "recvonly"});
    audioTransceiver.onTrack.subscribe((track) => {
        audioTransceiver.sender.replaceTrack(track); //this line will be hit
        track.onReceiveRtp.subscribe((rtp) => {
            console.log('audio data'); //this line will be hit
        });
    });

    const videoTransceiver = pc.addTransceiver("video", {direction: "recvonly"});
    videoTransceiver.onTrack.subscribe((track) => {
        videoTransceiver.sender.replaceTrack(track); //this line will be hit
        track.onReceiveRtp.subscribe((rtp) => {
            console.log('video data'); //this line will not be hit
        });
        track.onReceiveRtcp.subscribe((rtp) => {
            console.log('video data'); //this line will not be hit
        });
        track.onReceiveRtp.once((rtp) => {
            setInterval(() => videoTransceiver.receiver.sendRtcpPLI(track.ssrc!), 2000); //this line will not be hit
        });
    });

    pc.createDataChannel('dataSendChannel', {id: 1});

    let offer = await pc.createOffer();
    await pc.setLocalDescription(offer);

    console.log(offer.sdp);

    let answerSdp = <get answer from remote service>;

    console.log(answerSdp);
    await pc.setRemoteDescription({
            type: 'answer',
            sdp: answerSdp
        });

    console.log('answer applied');

Will result in a successful connection being established and audio data will start being received. However, no video data is ever received. If using a web browser the video comes through perfectly.

I have added the complete output of the program including debug logs. I can definitely see errors like werift-ice:packages/ice/src/stun/transaction.ts retry failed times:7 maxLimit:7 +0ms but have no idea what they mean.

[WEBRTC] RTX with Simulcast not working

Missing peerConnection.close() method

The peerConnection.ts file lacks close() method, which IMHO is a very basic method in RTCPeerConnection.

SDP validation fails if mid values do not match

werift-webrtc/packages/webrtc/src/peerConnection.ts

Line 1034 in 9ca4dab

throw new Error("Media sections in answer do not match offer");

Offer: Werift (mid: 0_srtp)
Answer: Google Camera Gen 2 (mid: 0)

Werift generates mid values that do not match the answer sdp (suffixed with strip). This causes the above failure. This is new behavior in this change:
32a3610#r77415945

For now, I am manually setting the mid values to to force a match (only because I know what the answer sdp will be ahead of time).
I believe the above matching code is incorrect, it should likely do a comparison against mLineIndex.

Datachannel performance

Hi, this looks like a very interesting project!

I was wondering if you have measured the maximum throughput of the data channel? It would be very interesting to know how the performance compares to that of other WebRTC implementations.

no response on second peer connection stun request

I've been having a hard time tracking this issue down, and was wanting to see if you had any insight:

Clients:
Offer: Safari iOS (on cellular)
Answer: Werift on Mac

On first run of connecting the peers, werift will successfully retrieve the srflx candidates from the STUN server. On second or third run, werift will fail to retrieve a response from the STUN server, causing the connection to fail. After a few minutes, the STUN server seems to start responding again.

I have observed this behavior with multiple different stun servers (with no quotas enabled). I only observe this behavior when the peer is on cellular. When the Safari iOS peer is on local network, Werift will successfully receive a STUN response every time.

I'm unsure why the cellular network peer would cause STUN requests to fail in werift. I verified that the requests are being sent, and no response is received on the datagram socket.

Do you have any ideas?

My guess is that werift is somehow sending bad stun requests after the first one.

TWCC regression

The problem occurs in after #95.

`RTCDataChannel` gets stuck as `dataChannelFlush` is never called

I'm testing the RTCDataChannel (version 0.8.3) and if I send multiple messages at the same time it gets stuck and the other channel never receives it. Debugging the code I've noticed RTCSctpTransport.dataChannelFlush() is never called after SCTP.receiveSackChunk(). And checking the reference implementation aiortc it's indeed missing. Check below:

aiortc: https://github.com/aiortc/aiortc/blob/01ff209cc38e887edeb05cba1845cf458b31a0ac/src/aiortc/rtcsctptransport.py#L1222

      self._update_advanced_peer_ack_point()
      await self._data_channel_flush()
      await self._transmit()

werift-webrtc:

werift-webrtc/packages/sctp/src/sctp.ts

Lines 599 to 600 in 6a5af13

this.updateAdvancedPeerAckPoint();

this.transmit();

To get rid of this bug I've monkey-patched RTCDataChannel as below:

    const rtcPeerConnection = new WeriftRTCPeerConnection()

    // Monkey patch missing `sctp.dataChannelFlush()` in `sctp.sctp.receiveSackChunk()`
    const createSctpTransport = rtcPeerConnection['createSctpTransport'].bind(rtcPeerConnection)
    rtcPeerConnection['createSctpTransport'] = () => {
      const sctp = createSctpTransport()
      const receiveSackChunk = sctp.sctp.receiveSackChunk.bind(sctp.sctp)
      const updateAdvancedPeerAckPoint = sctp.sctp.updateAdvancedPeerAckPoint.bind(sctp.sctp)
      let inReceiveSackChunk = false
      sctp.sctp.receiveSackChunk = (chunk: any) => {

Missing ice-lite support

Lack of ice-lite support means that this lib can not be used to establish a ICE+DTLS connection with ICE Lite servers.

If you add support for ice-lite I'll extensively test this lib against mediasoup and will make a handler to use it within mediasoup-client in Node (as we did for Python aiortc lib).

ice transport failures when there are multiple transports (non-bundle)

Here, any ice transport failure fails the whole connection I think:

werift-webrtc/packages/ice/src/ice.ts

Line 700 in a894f4b

this.checkListDone = true;

I believe that all the ice transport results should be iterated to see if anything in the checklist succeeded. Or check to see if nominated is not empty.

werift-webrtc/packages/ice/src/ice.ts

Line 250 in a894f4b

res = await this.checkListState.get();

I have a fix for this, but I wanted to make sure I am understanding this code correctly.

Support fragmentation packets for MediaRecorder

If trying to use MediaRecorder with an H264 stream which contains fragmentation packets, attempts to record will error out with:

Seems to be because here https://github.com/shinyoshiaki/werift-webrtc/blob/develop/packages/rtp/src/codec/h264.ts#L77 if the unit type is 28/29 it will return a packet with an undefined payload.

`rolloverCounter` can get negative

I noticed that during some long-running stream I end up getting an exception which originates here because the value of rolloverCounter gets -1 at some point.
Probably there is something wrong with the update rule.

Specify server port/port range

@shinyoshiaki First of all, thanks for this awesome library.

I would like to use this library to start webrtc server for comunicating over datachannels. I looked at the examples and managed to do so on my local computer. Now I would like to host this on server. But my hosting provider supports listening to only limited number of udp ports and that too only in a specific range.
So where should I specify the port/port range? Would be very grateful to you if you could provide the answer with respect to this example https://github.com/shinyoshiaki/werift-webrtc/blob/develop/examples/datachannel/answer.ts and the corresponding client side https://github.com/shinyoshiaki/werift-webrtc/blob/develop/examples/datachannel/offer.html
I am looking for something similar to that provided by another nodejs webrtc library https://github.com/geckosio/geckos.io#new-in-version-170

In some cases, video does not play after event ontrack is triggered on the client

Hello! I moved my project from wrtc to werift. Due to the fact that 1 has different results between the first and subsequent server launches - apparently wrtc has some dependencies that store variables in memory bound to the process, so the server on wrtc does not work stably, the same happens if you use webdriver through puppeteer or playwright. But at werift this moment works stably, but I ran into a problem with reconnecting werift.

Description of the problem

When two or more room clients connect to the server at the same time, the video is played, but if you first connect one user, and then reconnect again, then his video is never played. Also, this problem occurs when about 5 users are connected and several users reload the page at the same time, but this moment is more difficult to track, so I temporarily set the disconnect from the client when clicking on the button to close the full screen video. And the listener then connects the disconnected but active user in the room.

Problem reproduction

In my project, you can make sure that the moment with a single reconnect worked with wrtc but does not work with werift.
I have checked all possible options, but everything suggests that the problem may be at a lower level of code than my application. That's why I'm writing this question because perhaps my project example will help you find a hard-to-find problem.

Result of reconnection to wrtc:

Result of reconnection to werift:

To reproduce this examples need:

Install master (werift) or wrtc (wrtc) branch of https://github.com/kolserdav/werift-sfu-react project by instruction https://github.com/kolserdav/werift-sfu-react/blob/master/docs/CONTRIBUTING.md
Create room and click to copy button with room id and unique user id url:
Open room as new user in new tab and split by difference pages.
Click by second video and while opened full video screen to ckick by close button:

Add-ons

I don't see any difference between normal and non-playable video streams:

Perhaps you will have some ideas.

[WEBRTC] Implement MediaPlayer

I am very happy to see that you implemented the MediaRecorder interface to save streams to webm files. I am probably going to replace my own implementation and try yours.

Are you also planning to create an interface which make streaming from webm files possible, i.e., something like a MediaPlayer (which is not part of the standard WebRTC infrastructure)?

dataChannel bug

hi! testing stuff I came across a max stack overflow error caused by this line:

`dataChannelFlush()` starves sending only one data buffer per entire event loop

The problem is in the following loop of RTCSctpTransport.dataChannelFlush() function:

werift-webrtc/packages/webrtc/src/transport/sctp.ts

Lines 250 to 286 in ac1328f

    
           while ( 
        
             this.dataChannelQueue.length > 0 && 
        
             this.sctp.outboundQueue.length === 0 
        
           ) { 
        
             const [channel, protocol, userData] = this.dataChannelQueue.shift()!; 
        
             let streamId = channel.id; 
        
             if (streamId === undefined) { 
        
               streamId = this.dataChannelId!; 
        
               while (Object.keys(this.dataChannels).includes(streamId.toString())) { 
        
                 streamId += 2; 
        
               } 
        
               this.dataChannels[streamId] = channel; 
        
               channel.setId(streamId); 
        
             } 
        
             if (protocol === WEBRTC_DCEP) { 
        
               this.sctp.send(streamId, protocol, userData); 
        
             } else { 
        
               if (channel.maxPacketLifeTime) { 
        
                 expiry = Date.now() + channel.maxPacketLifeTime / 1000; 
        
               } else { 
        
                 expiry = undefined; 
        
               } 
        
               this.sctp 
        
                 .send( 
        
                   streamId, 
        
                   protocol, 
        
                   userData, 
        
                   expiry, 
        
                   channel.maxRetransmits, 
        
                   channel.ordered 
        
                 ) 
        
                 .then(() => this.dataChannelFlush()); 
        
               channel.addBufferedAmount(-userData.length); 
        
             } 
        
           }

My use case is that I call send every time the user changes a text in a text-editor. And when I use Werift instead of the native wrtc package the other side gets the changes really slowly until the user stops typing. Upon investigating it I've found out that the this.dataChannelQueue in this loop increases a lot because this.sctp.outboundQueue is always with one item to be sent.

As it turns out, every time a this.sctp.send is called inside this loop chunks are immediately added to this.sctp.outboundQueue and the loop ends right away. So, it's only going to execute in the next event loop but once again this repeats one by one until the this.dataChannelQueue gets empty.

Comparing this function with the reference implementation in aiortc they look like the same but there is a fundamental difference between Python AsyncIO and JavaScript Promises. Python AsyncIO enqueue awaitable functions to be run on the next event loop, but JavaScript Promises runs its executor function synchronously. So, even though the SCTP.send() is an async function the code is going to execute synchronously and this function adds chunks to outboundQueue and makes the former loop to stop. The loop logic is then flawed in JavaScript as it's going to always dequeue only one item from dataChannelQueue and then it stops (Having this while loop or just a if is the same in JavaScript).

Upon investigating a solution for it the easiest one is to wrap the SCTP.send() in a Promise.resolve.then() as JavaScript always enqueue then executor functions. Below is the mokey-patch I've made to make it work.

    const rtcPeerConnection = new WeriftRTCPeerConnection({ iceServers })

    // Monkey patch `sctp.sctp.send()` to be queued on next event loop otherwise `sctp.dataChannelFlush()` "starves"
    // sending only one buffered data on each event loop
    const createSctpTransport = rtcPeerConnection['createSctpTransport'].bind(rtcPeerConnection)
    rtcPeerConnection['createSctpTransport'] = () => {
      const sctp = createSctpTransport()
      const send = sctp.sctp.send
      sctp.sctp.send = (...args: any[]) => Promise.resolve().then(() => send(...args))
      return sctp
    }

With this solution the other side gets the updates much faster but it's not fluid. The other side gets the stream in chunks of text instead of letter by letter. The problem with that solution is that it's going to enqueue everything from this.dataChannelQueue not giving any chance to some finished IO waiting in the event loop. It would be nice to have an async dataChannelFlush with the loop logic fixed so this would never happen. Also, looks like Werift's Transport.send function implementations are not async as well so it always halts the entire event loop until the IO finishes.
