Tencent cloud provides a full set of technical documents and source code to help you quickly build an audio and video small program, but no matter how good the source code and documentation also have learning costs, in order to debug as soon as possible, we also provide a free one-key deployment service: With just a few clicks of the mouse, you can get an audio and video applet under your own account. At the same time, a test server with an independent domain name is attached, so that you can quickly build your own test environment in 5 minutes.

At this time, subsequent operations can be carried out.


At this time, checking the status of Tencent cloud through the small program developer tool will not show that it has been opened. The opened status will be synchronized to the wechat developer tool only after the first deployment of the development environment.
