, where we control the playback time primarily with PTS. Use Av_frame_get_best_effort_timestamp for decoded avframe to get pts. Time_baseWe notice that PTS is a shaping data, Time_base is the unit of PTS, and pts times time_base to get the actual time. Only the time_base obtained in Avstream is right, and other places may have problems. Audio and video synchronization strategyThere are generally three ways to sync audio to video, sync video to audio, and sync video to external time. General para
