I can use the TRTC web SDK in a local development environment but not after it is deployed online. What should I do?
To ensure data security and protect users’ privacy, browsers allow access to the mic and camera only in secure environments, for example, when https, localhost, or file:// is used for access. Because HTTP is not secure, browsers block access to media devices when HTTP is used.
If you can use the SDK in a local development environment but cannot capture data from the camera or mic after deploying it to the web, check whether your webpage is deployed using HTTP. If so, use HTTPS instead and make sure you have a valid HTTPS certificate.
1. TRTC has a main video stream (main stream) and an sub video stream (sub stream).
2. The camera is published through the main stream, and the screen sharing is published through the sub stream.
3. The main video stream includes: big stream and small stream. By default, TRTC.startRemoteVideo plays the big stream, and the small stream can be played through the small parameter. Refer to: Optimize Multi-Person Video Calls.
If your browser is not listed in the above document, you can open the TRTC compatibility check page with the browser to test whether it fully supports WebRTC.
Can I change the video profile(resolution, frameRate, bitrate)?
What should I do if the error "Permission denied" occurs when I use the TRTC web SDK in iframes?
To use WebRTC in iframes, you need to add the following attribute to the iframe tag to obtain the permissions needed.
Mic, camera, and screen sharing permissions:
It may be because of the browser’s autoplay policy, which causes the “PLAY_NOT_ALLOWED” error. To solve the problem, please see Handle Autoplay Restriction.
What triggers the trtc.on(TRTC.EVENT.KICKED_OUT) event?
The event is triggered when a user is removed from a room, for example, when the same user ID is used to log in from different devices or when the RESTful API RemoveUser is called to remove a user. For more information, see KICKED_OUT。
Note:
Repeated login is not allowed by the SDK (it may cause call exceptions) and should be avoided at the business layer.
Causion for Using Vue 3
When the Vue3 framework is used, it is necessary to use the markRaw interface to mark the trtc instance to avoid the conversion of trtc into the Proxy object by Vue, which may cause some unexpected problems.
import{ markRaw }from'vue';
const trtc =markRaw(TRTC.create());
