Method and system for realizing H264 video coding format play optimization

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.

Description

technical field [0001] The present invention relates to the technical field of video playback, in particular to a method and system for realizing H264 video encoding format playback optimization on a mobile phone platform. Background technique [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). The fields of communication and storage are more and more widely used, but the price of the superior performance of the H264 standard is the increase of computational complexity, which increases the requirement for the decoding capability 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 insuffic...

[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
