Abstract

This application discloses a PTS reset processing method for streaming media, a display device and a storage medium, which calculates the first PTS difference between the first injected frame and the second injected frame that are continuously injected; when the first PTS difference When the absolute value of the value is greater than the maximum error tolerance value, obtain the PTS value of the frame to be injected after the second injected frame; calculate respectively the second PTS difference between the frame to be injected and the second injected frame, and the frame to be injected and the second frame to be injected A third PTS difference between injected frames; when the absolute value of the second PTS difference is less than the absolute value of the third PTS difference, based on the first injected frame, the second injected frame and the frame to be injected The transport stream performs reset processing. This application will only perform reset processing if it is ensured that the jump of the PTS value is due to a normal reset, so as to ensure the reliability of the reset processing and avoid playback problems such as out-of-sync audio and video in the transport stream caused by the jump of the PTS value. user experience.

Description

technical field [0001] The present application relates to the technical field of streaming media playback, and in particular to a PTS reset processing method for streaming media, a display device, and a storage medium. Background technique [0002] Streaming media, also known as streaming media, is the current mainstream TV application. In the field of streaming media on-demand and live broadcasting, the HLS (HTTP Live Streaming, Hypertext Live Streaming) protocol is a widely used streaming media transmission protocol. The HLS protocol mainly uses TS (Transport Stream, Transport Stream) as its audio and video encapsulation format. Each frame of TS in the audio and video includes a PTS (Presentation Time Stamp, displaying a timestamp), and the playback progress of the streaming media file is displayed by displaying the timestamp. [0003] In the television system, according to the requirements of the TS encapsulation format, the PTS in the TS has a maximum time that can be ...
