Autoplay
Most browsers' autoplay policies require users to perform at least one interaction before playing a video with sound. This is because users generally do not expect a newly opened webpage to produce sound without warning.
Additionally, some browsers do not allow autoplay for videos without sound. For example, iOS Safari in low power mode and the embedded WeChat browser on iOS.
This means that before user interaction, autoplay or manually calling the play interface to play audio/video may fail, resulting in no sound or the video not being visible.
Therefore, the POLYV live streaming player implements autoplay using the following two methods.
Muted Playback, Guide Users to Restore Volume
First, mute the video stream, then play it. After successful playback, guide the user to manually restore the sound.
Listen for Playback Failure Callback, Guide Users to Interact
Listen for the playback failure callback, display a large play button, and guide the user to manually click it. Video playback is triggered by the gesture.
