Problems solved by technology

[0002] The H264 standard is a new generation of video coding standard jointly formulated by the International Telecommunication Union (ITU) and the International Organization for Standardization (ISO). Communication and storage fields are more and more widely used, but the price of superior performance of H264 standard is the increase of computational complexity, which increases the requirements for decoding capabilities of playback devices
With the continuous development of mobile network technology, using mobile phones to watch videos has gradually become a trend, but the highly complex decoding and calculations are a test for mobile phones when playing videos, and video playback is often not smooth due to insufficient computing and decoding capabilities and mosaic
[0003] The current mobile phone platforms basically use ARM (Asynchronous Response Mode, Asynchronous Response Mode) as the computing CPU. ARM has its own characteristics of data reading and output, that is, reading and output in units of 4 bytes. When the read data is less than 4, it will cause a waste of reading or output speed
In addition, under the mobile phone platform, when the client requests H264 encoded video stream, the parsing speed of H264 is slow

Embodiment Construction

[0032] The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are illustrated.

[0033] figure 1 It shows a flow chart of a method for implementing H264 video encoding format playback optimization under the mobile phone platform provided by the embodiment of the present invention.

[0034] Such as figure 1 As shown, the method flow 100 for realizing the playback optimization of the H264 video encoding format under the mobile phone platform includes: steps 102-112; the details are as follows:

[0035] Step 102, the mobile phone client sends an RTSP (Real-Time Streaming Protocol, Real-Time Streaming Protocol) request to the server, requesting the video stream on the server.

[0036] Step 104, the server encodes according to the H264 encoding format, and sends the RTP (Real-time Transport Protocol) data packet in the form of UDP (User Datagram Protocol, User Datagram Protocol). ...

Abstract

The invention discloses a method and system for realizing H264 video coding format play optimization at a cell phone platform. The method comprises the following steps: a cell phone client transmits a real-time streaming media protocol (RTSP) request to request a video stream on the server; the server encodes according to H264 coding format, and transmits a real-time transmit protocol (RTP) data packet in a mode of user data protocol (UDP); the client receives the RTP data packet, resolves the RTP data packet into naked code stream data and decodes the naked code stream; and the decoded stream data is outputted and displayed in videos. According to the invention, the receiving, resolving, decoding and display processes of a cell phone terminal are optimized, so that H264 format file play is improved in speed and quality.
