Problems solved by technology

[0003] However, the delay of the first frame of streaming media provided by some operators exceeds 40ms, and the delay time of video frames after a certain period of time is all within 40ms. However, since the first frame is illegal, all video frames are considered illegal. so the user cannot see the video
For example, in the streaming live broadcast of Hong Kong 3HK operator, the first frame of video is delayed by 400ms, which is far more than 40ms, and the delay time of video frames after 2 seconds is all within 40ms, but because the first frame is illegal. The user cannot see the video screen
Therefore, there is a problem with the mechanism by which the NuPlayer player renders video data

Embodiment Construction

[0015] refer to figure 1 As shown, it is an operating environment diagram of a preferred embodiment of the streaming media rendering processing system of the present invention. The streaming media rendering processing system 11 runs in the player 10 of the mobile device 1 , and the mobile device 1 also includes a buffer 20 . In this embodiment, the associated mobile device 1 is a mobile phone, and the player 10 is a NuPlayer player.

[0016] When streaming media playback is required, the mobile device 1 downloads data packets from an operator server (not shown in the figure) and caches them in the buffer 20 . The player 10 acquires the data packets in the buffer 20, parses the data in the data packets to the data queue, renders the audio and video data in the data queue, and finally decodes and plays them. In this embodiment, the associated data packets are RTP (Real-time Transport Protocol, real-time transport protocol) data packets or RTSP (Real-time Streaming Protocol, re...

Abstract

Provided is a streaming media rendering processing method that comprises steps of: acquiring the delay time T of each video frame in the video data of a data packet; comparing the delay time T with a first preset value T1 and a second preset value T2; when the delay time T is less than or equal to the first preset value T1, outputting the video frame and corresponding audio data; when the delay time T is more than the first preset value T1 but less than the second preset value T2, controlling the audio data corresponding to the video frame to be delayed by same delay time T and then outputting the video frame and the corresponding audio data; and when the delay time T is more than or equal to the second preset value T2, discarding the video frame and outputting audio data. The invention also provides a streaming media rendering processing system. The streaming media rendering processing method and system may improve streaming media playing compatibility of mobile devices.

Description

technical field [0001] The present invention relates to a data processing method and system, in particular to a streaming media rendering processing method and system. Background technique [0002] On phones using Android and a Qualcomm solution, streaming uses Qualcomm's NuPlayer player. When NuPlayer player plays streaming media, it mainly includes acquiring data, parsing data to data queue, rendering (Render) data and decoding process. When rendering video data, if the video frame delay exceeds 40ms, the video frame will be discarded, and this frame of video cannot be seen in the user interface. If the first frame of video data is delayed by more than 40ms, all video frames are defined as illegal video, so that the video picture cannot be seen on the user interface. [0003] However, the delay of the first frame of streaming media provided by some operators exceeds 40ms, and the delay time of video frames after a certain period of time is all within 40ms. However, since...
