Hi @aaronxu33, thanks for the post.

Sorry to hear you’re having issues when subscribing to videos in a custom UI implementation. When you say that there is no response on the 3rd Subscribe call, can you please clarify what you mean (e.g. a callback isn’t triggered, there is no video rendered, etc.)?

Thanks!

the callback isn’t triggered, there is no video rendered.

Hi @aaronxu33,

Can you please confirm which callback(s) you are using?

Thanks!

sorry that I gave a wrong message, we don’t implement the callback on subcribe video.
any advise for further investigate for it?

Hi @aaronxu33,

In order to determine the reason for a video subscription failing, you will need to implement the onSubscribeUserFail callback. If you can get the fail_reason parameter from this callback, we can look into what’s going wrong with your subscription.

Thanks!

Hi Jon,
we add the callback for video subscribe, the SDK didn’t trigger the callback.

Hi @aaronxu33,

Thanks for checking that. I also noticed that you are on an older version of the SDK. Can you please try updating to the latest version and letting me know if the issue is still present?

Thanks!
