Twilio-video.js: [Urgent] 'Client is unable to apply a remote media description' on Chrome (Windows)

Created on 22 Oct 2020  路  18Comments  路  Source: twilio/twilio-video.js

We've seen thousands of Client is unable to apply a remote media description errors since mid-September.
This results in no video/audio for participants in a peer-to-peer call.

99.5% of affected users are Windows 10, and of those 52.5% are Chrome 85.0.4183 and 46.4% are Chrome 86.0.4240.

Unsure if device compatibility issues between Windows 10 Chrome & other devices, such as Android devices. We're aware that in one specific case, using Firefox resolved the issue.

We have thousands of examples of the following which is logged to Console. Here's two examples:

We have also been experiencing this (already reported here: https://github.com/twilio/twilio-video.js/issues/963), and have also noticed an uptick in occurrences recently.

dambusm picture dambusm on 27 Oct 2020

@anna-vasilko @manjeshbhargav have you been able to see anything at your end from the room SIDs I shared?

mfields3 picture mfields3 on 2 Nov 2020

@mfields3

I took a look at the Rooms you provided, and did not notice anything unusual in the server logs, since this is a client error. Can you let us know exactly what error message is displayed just above the SDP in the javascript console? Also, it would be great if you can let us know if there are any repro steps.

Thanks,

Manjesh

manjeshbhargav picture manjeshbhargav on 10 Nov 2020

@manjeshbhargav

The error just before the SDP is:
Calling setRemoteDescription with an RTCSessionDescription of type "answer" failed with the error "Failed to execute 'setLocalDescription' on 'RTCPeerConnection': Failed to set local offer sdp: Failed to set local video description recv parameters for m-section with mid='1'.".

We've personally been unable to replicate it, although it happens on a daily basis - thousands in the past 7 days.
Is this likely to be caused by specific browser versions/OS's? If so we can look to start capturing logs of what the remote party is using - right now our error reports tell us the browser version/OS of the participant where this error is logged.
Do let me know if there's anything else we should try and log.

mfields3 picture mfields3 on 12 Nov 2020

Thank you for the update @mfields3 -
I am looking at this issue, and so far have not been able to reproduce it. We see that this error comes from this line in chromium's code, but do not see what causes it. I am continuing to investigate.

If its possible to capture the complete console log from the browser where this error happens that could be useful. About the remote party - we can look into our server logs and find the browser/os for the remote party if we know the room sid.
Can you share all room-sids (and participant sid) that encountered this error - I would like to see if there is some pattern in the remote browser/os when this error happens.

Thanks,
Makarand

Hey @makarandp0 we've been experiencing some odd behaviour of a similar description that is also intermittent, and we've not been able to recreate it ourselves. However, our client is reporting one or two issues every other day. I'm afraid we've not been able to capture any logs but I was desparately hoping I could share the Room ID and participant ID in case it's somewhat related as we're a bit stuck with this one!

Room: RM5f81d7c82ff69524962a548ff72cc4e0
Participant: PAbb7935e93bf5aa6eaf18031b8abfd4a6

Apologies if no use, but hope it helps, would be grateful if you could provide any advice if anything from logs appear regarding errors.

JamieBradders picture JamieBradders on 12 Nov 2020

@makarandp0 @manjeshbhargav
We're going to start logging Room SIDs alongside these errors so we can provide you with a large list of affected SIDs - currently it's a manual process to find out Room SIDs for a given error which is surfaced via our JS bug tracking software.

I'm at least aware that one of our customers were experiencing this issue when using AMD Ryzen laptops with integrated graphics where the other party was an Android device. Unsure if this is of any significance.

Thank you @lutetium174 for the update.
Regarding Call to getUserMedia failed that indicates failure to get media - It was logged on FireFox users browser right? Looking at room logs, I do see that participant PA3ad1c1dd8209ae8b382643fc38f4c1ef published two tracks

2020-11-19T17:11:29.562Z: P2 published audio: mic-1605805861047 / MT2cca16a8717d1bbea8e1b9f4b6dbd243 revision: 3 priority: standard

and participant PA1be2bcd56132c3b51f1a1fb2b7263564 published just an audio track

2020-11-19T17:13:30.822Z: P3 published audio: mic-1605805998202 / MTab54ec55975a2b1b027ccbf030e0e76f revision: 2 priority: low

So I guess the getUserMedia was logged when Firefox Participant tried to acquire media during the reconnect attempt. Was the SDP error on Chrome participant seen before or after Firefox user reconnected?
I want to see if there is any correlation between firefox user failing to getUserMedia and Chrome user failing to apply SDP.
can you attach full console logs for these participants ? That could help answer some of these questions.

Hi @makarandp0,

The error on chrome was seen after the firefox user reconnected. As far as I'm aware neither party were able to see nor hear one another at any point during the call, so I'm not sure if the initial 13 second connection was correctly established.

The logged output I've provided is unfortunately all I have at present. If I manage to get more examples and a more detailed log, I will let you know

We're seeing this very often and also have the same symptoms where we are getting users with just audio and not video.

Seems this is error occur when i use npm twilio-video 2.8.0 package (i used vuejs with webpack), when i use src="//media.twiliocdn.com/sdk/js/video/releases/2.8.0/twilio-video.min.js" it works fine

phucduong-ncc picture phucduong-ncc on 28 Nov 2020

Thank you @phucduong-ncc, This is very interesting - Does this issue reproduce consistently when you use npm package? Would it be possible for you to share your package.json + any scripts that you use to generate your application. I am trying to reproduce this issue locally and have not had much luck yet.

Thanks,
Makarand
