Abstract

The invention discloses a streaming media PTS reset processing method, a display device and a storage medium. The method comprises the following steps: calculating a first PTS difference value betweena first injected frame and a second injected frame which are successively and continuously injected; when the absolute value of the first PTS difference value is greater than the maximum fault-tolerant value, acquiring a PTS value of a to-be-injected frame after the second injected frame; respectively calculating a second PTS difference value between the to-be-injected frame and the second injected frame and a third PTS difference value between the to-be-injected frame and the first injected frame; and when the absolute value of the second PTS difference value is smaller than the absolute value of the third PTS difference value, performing reset processing on the transport stream based on the first injected frame, the second injected frame and the to-be-injected frame. According to the method and the device, the reset processing can be performed only when the PTS value hopping condition is ensured to occur due to normal reset, so that the reliability of the reset processing is ensured, the playing problems of asynchronous audio and video in the transport stream and the like caused by the PTS value hopping condition are avoided, and the user experience is optimized.

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 ...
