Yes, most real-time audio and video SDKs support mirroring functionality. Mirroring allows the video stream to be flipped horizontally, which is commonly used in scenarios like video conferencing, live streaming, or when a user is facing a camera and wants their image to appear correctly on the other side (e.g., a virtual meeting where participants expect to see each other as they would in person).
For example, if a user is using a front-facing camera on a mobile device, the video stream may appear reversed (left becomes right) unless mirroring is enabled. By enabling mirroring, the video stream is flipped to match the user's natural perspective.
In the context of cloud-based real-time communication solutions, Tencent Cloud's TRTC (Tencent Real-Time Communication) SDK supports mirroring. Developers can easily configure mirroring in the SDK settings to ensure the video stream is displayed correctly for end-users. This is particularly useful in applications like online education, remote collaboration, or social live streaming.
Example use case:
A user joins a virtual classroom via a mobile app. The front-facing camera captures their image, but without mirroring, their movements appear reversed (e.g., raising the left hand looks like raising the right hand). By enabling mirroring in the TRTC SDK, the video stream is flipped, making the user's actions appear natural to other participants.
