Syncing Send Video and Send Audio in meeting SDK

To ensure that both the video and audio remain in sync during your Zoom meeting bot’s operation, you need to synchronize their playback. Here are some suggestions to achieve synchronization:

  1. Match Frame Rate and Audio Sampling Rate: Ensure that the frame rate of your video matches the audio sampling rate. In your case, the video is playing at 30fps, and the audio is sampled at 44100Hz. These rates should ideally match for smooth synchronization.
  2. Adjust Sleep Duration Dynamically: Instead of relying on a fixed sleep duration to control frame rate, calculate the actual time taken to process each frame and adjust the sleep duration dynamically to maintain synchronization.
  3. Implement Audio-Video Sync Mechanism: Create a mechanism to synchronize the audio and video streams. You can achieve this by timestamping each audio and video frame and ensuring that they are played back in sync. For example, you can timestamp each audio chunk and match it with the corresponding video frame.
  4. Consider Using Multimedia Frameworks: Instead of manually handling audio and video playback, consider using multimedia frameworks or libraries that provide synchronization features out of the box. These frameworks often handle synchronization intricacies more efficiently.
  5. Monitor and Fine-Tune: Continuously monitor the synchronization during playback and fine-tune your synchronization mechanism as needed. It may require experimentation and adjustments to achieve optimal synchronization.

By implementing these strategies and fine-tuning your synchronization mechanism, you can ensure that both the audio and video streams remain in sync throughout the Zoom meeting.
