attemped to turn on audio_compatible_mode but that wouldn’t work for me ( running without cross origin isolated so maybe thats why )

How To Reproduce

  1. Join session on Safari desktop

Session ids:

Hey @sam9

Thanks for your feedback.

After investigating the session logs, we found that WebRTC audio is not enabled. Could you please check the JWT token again?

It is not affected by SharedArrayBuffer, and you can enable it without cross-origin isolation.

Thanks.

@vic.yang Thanks… it wasn’t working because when I originally tried audio_compatible_mode the mediaSdkChange wasn’t firing “audio” type on Safari but it was firing “share” so I just added “share” for now to accept that as audio encode/decode on safari ready:

onMediaSdkChange = async (payload: MediaSDKEncDecPayload) => {
        if (
            (payload.type === "audio" || payload.type === "share") &&
            payload.result === "success"
        ) {
            if (payload.action === "encode") {
                // encode for sending audio stream (speak)
                this.audioEncode = true;
            } else if (payload.action === "decode") {
                // decode for receiving audio stream (hear)
                this.audioDecode = true;
            }
        }

        if (this.isSafari() && this.audioEncode && this.audioDecode) {
            const { videoRoom } = this.getStateSnapshot();

            videoRoom.off("media-sdk-change", this.onMediaSdkChange);

            this.audioEncode = false;
            this.audioDecode = false;

            this.showSafariAudioPrompt();
        }
    };

1 follow up questions if you could since I am going to push this into production today I think:

Is it okay to only set audio_compatible_mode for Safari users and non-Safari run without that turned on?

Let me know if theres any other things I need to know about

Hey @sam9

Thank you very much for sharing your concerns about usage.

The media-sdk-change was initially introduced to address issues with legacy Safari. We apologize for the delay in updating our documentation. Subsequently, we have introduced a new audio solution (WebRTC audio , enabled via audio_compatible_mode field in JWT token), which does not have these issues and eliminates the need to listen for the media-sdk-change event.

Is it okay to only set audio_compatible_mode for Safari users and non-Safari run without that turned on?

Yes. It’s Okay for the setting.

Thanks
Vic
