Course Introduction：To solve the problem of restricting HTML5 video automatic playback, the first thing to do is to clarify the answer: it can be effectively dealt with by mute automatic playback, user interaction playback, checking video format and path, and paying attention to browser policy updates. Specifically: 1. Add muted attributes to the video to achieve muted automatic playback; 2. Call the play() method after the user clicks on the page element to restore the sound or start the playback, which is especially suitable for mobile terminals; 3. Check the video format compatibility, path correctness and server configuration to ensure that the video can load normally; 4. Pay attention to changes in browser policies and capture playback errors through JavaScript to adjust the strategy in time, thereby improving the success rate of automatic playback.

Course Introduction：To handle HTML5 media playback events, you need to listen to play, pause, ended, timeupdate and other events and respond with JavaScript. Pay attention to the browser's automatic playback restrictions when controlling playback behavior, and use timeupdate to synchronize progress. For example: 1) Update the UI or record duration through addEventListener by binding play, pause and other events; 2) When calling .play()/.pause() to control the play state, errors need to be captured to deal with user gestures or mute requirements; 3) Listen to the timeupdate event to realize time display or progress bar update to improve the interactive experience.
