Problems solved by technology

Users generally think that the smaller the step size, the faster the response should be, but in fact, the response is slow when skipping a small step forward, which is contrary to user expectations.
It is because skipping a small step forward will clear the code stream in the buffer that will be used immediately, and download it again, which will cause waste and greatly affect the user experience.

[0069] refer to figure 1 , the processing method of streaming media data includes buffering step S1 and playing step S2 executed simultaneously. refer to figure 2 and image 3 , in the first embodiment, the buffering step S1 can adopt the buffering step S11, this embodiment adopts the circular buffer to store the code stream data, the ring buffer stores the code stream that has been played and the code stream to be played, and when the video is played, from the reading position Read the code stream to be played backward step by step, decode and play it, and the code stream that has been played is the played code stream, and the video playback is played in sequence from front to back in time, such as image 3 Playback is read clockwise.

[0070] When executing the caching step S11, first execute step S11 to determine whether the played code stream is greater than the preset threshold, and if the played code stream is greater than the preset threshold, then execute step S112...

[0086] refer to Figure 5 and Image 6 and combine figure 1 , the processing method of streaming media data includes buffering step S1 and playing step S2 executed simultaneously. The cache in this embodiment is implemented in the form of a one-way linked list. The cache stores the played code stream and the code stream to be played sequentially from the head of the linked list. Play, the already played is the played code stream, the video playback is played in sequence from front to back, such as image 3 Read and play from left to right, and the write position is set at the end of the linked list. When writing data, apply for an address and write in order.

[0087] In the second embodiment, the buffering step S1 may adopt the buffering step S12. Specifically, step S121 is first performed to determine whether the amount of data in the cache is less than the preset total threshold. When the amount of data in the cache is less than the preset total threshold, it indicates I...

Abstract

The invention provides a method and device for processing stream media data. The method comprises the steps of storing played code stream and to-be-played code stream through a cache; if the played code stream is greater than a preset threshold, arranging a writing position at the front end of the played code stream and covering the played code stream with a new code stream according to the writing position; if the played code stream is smaller than the preset threshold, not releasing or covering the played code stream; judging whether the new code stream is in the played code stream or the to-be-played code stream or not during jump playing; and if so, arranging a reading position at a target position of jump playing and dividing the played code stream and the to-be-played code stream again according to the new reading position. According to the method and the device, the utilization rate of the played code stream and the to-be-played code stream can be well ensured, meanwhile, a user can be provided with a fast jump playing response and the user experience is improved.

Description

technical field [0001] The invention relates to the field of streaming media data, in particular to a processing method for streaming media data and a processing device for streaming media data. Background technique [0002] There are two main ways to play multimedia information such as audio and video on the network, playing after complete download and streaming, and streaming refers to receiving multimedia data while presenting the content of multimedia data to users, and live programs Only streaming is available. Multimedia files are usually relatively large, and there is a relatively large delay in playing after downloading. [0003] Because streaming transmission has the characteristics of playing while receiving, it is easily affected by network delay and network jitter. In order to ensure smooth playback, it is necessary to add a buffer module to the playback terminal design. When the code stream in the buffer reaches a certain threshold It starts to play, and then ...
