Hello Team,

Sample web application is working fine in Chrome, while coming to safari we are getting error messages with remote mixed stream in MCU.

Please find below attached screenshot of console log .

Thanks,

Nikhil

Hi, Nikhil

Could you provide more information, e.g reproduce steps and Safari version etc

Thanks

Yanbin

Nikhil_kumar__Doosar · ‎01-22-2019

Hi Yanbin,

Simply we download the framework, and started MCU server in AWS(GPU is not enabled) with self signed certificates.

Opened index.html from node server with port number 80 in safari browser (v12.0.2). We got issue as "Receive remote stream without subscription".
Our local stream is published successfully, and visible at other end.But at safari user end remote mixed stream is not subscribed.

While compare to chrome browser, its working fine.

Please find below attachment for console log screenshot.

Thanks,

Nikhil

Hi, Nikhil

We also found this issue on our release testing cycle. It seems the safari issue and related to machine hardware. It works fine on some of machines while works abnormally on others during our testing. We will monitor safari related fix closely .

Thanks

Hi Nikhil When the problem arises in January, the MCU version is 4.1. The problem has been solved in 4.2. I tested that Safari can subscribe to mix streams. Please try again. If there is a problem, please send out the specific replication steps. I will follow up. Thank you.

Nikhil_kumar__Doosar · ‎05-06-2019

Hi Zhao,

Simply we download the framework(4.2), started MCU server in AWS(GPU is not enabled) with ssl.

Opened index.html(https://abc.com:3004) in safari browser (v12.0.2). We got issue as "Receive remote stream without subscription".
Our local stream is published successfully, and visible at other end.But at safari user end remote mixed stream is not subscribed.

Can you help me on this.

Thanks,

Hi,

We have some questions about your case:

1. Did the subscription fail on safari every time or sometimes?

2. How about subscribing forward streams? (add /?forward=true)

3. Did you subscribe the stream published from safari or from chrome?

Nikhil_kumar__Doosar · ‎05-22-2019

Hi,

1 subscription fail on safari every time (forward=false)

2 working fine on forward=true

3 we tested for safari to safari and chrome to safari both are not working for forward=false

Thanks,

Nikhil kumar

Li_C_Intel · ‎05-22-2019

Hi, According to your description, the settings of mixed stream may not be suitable for safari. Please check the format of your mixed stream configuration. If the codec is H264, make sure h264 is enabled through ./video_agent/install_deps.sh

Li__Zunlong · ‎05-23-2019

I came across the same issue as Nikhil described.

I have installed h264 deps. I set the view's video format to { "profile" : "CB", "codec" : "h264" }.

Hello,

Any update would be appreciated.

Thanks,

Hi,

We are trying to resolve this issue, but it may be need some time to find the root cause.

Now we find a workaround for this issue.

you can put conference.subscribe operation into a setTimeout scope, and timeout set to 1000 such as follow:

                       setTimeout(function (){
                            conference.subscribe(stream, {
                                audio: {codecs:[{name:'opus'}]},
                                video: true
                            }).then((subscription) => {
                                subscriptionForMixedStream = subscription;
                                
                                let $video = $(`<video controls autoplay id=${stream.id} style='display:block'>this browser does not supported video tag</video>`);
                                $video.get(0).srcObject = stream.mediaStream;
                                $('body').append($video);

                            };},1000);
