You need to register the callback when calling the method. After you successfully register the video frame observer, the SDK triggers this callback each time it receives a video frame. You need to set your preferred video data in the return value of this callback.

The default types of pixel format () for the raw video are as follows:

      You can get raw video data collected by the local device through this callback and preprocess it as needed. Once the preprocessing is complete, you can directly modify videoFrame in this callback, and set the return value to to send the modified video data to the SDK.

      If you need to send the preprocessed data to the SDK, you need to call first to set the video processing mode to read and write mode ().
