A method and system for playing local video on mobile platform

Abstract

The invention discloses a method for playing a local video on a mobile platform, and the method comprises the following steps of: S11: notifying a control module when a media file packaged in an F1 format needs to be played; S12: applying the memory of a control module for saving content transcoded and output by a transcoding module, and transmitting the address of the media file packaged in the F1 format to the transcoding module; S13: reading the media file positioned on a disc and packaged in the F1 format, through the transcoding module, transcoding into media file data packaged in an F2 format, and saving in the memory; and S14: transmitting the media file data generated through transcoding and packaged in the F2 format to a system player through a network protocol according to the request of the system player through a customized protocol transmission module to be played by the system player. The method disclosed by the invention saves the time and disk space expenditure caused by video playing in the prior art. Besides, the invention also discloses a system for playing the local video on the mobile platform.

Description

technical field [0001] The invention relates to the technical field of video playback on a mobile platform, in particular to a method for playing local video on a mobile platform. In addition, the invention also relates to a system for playing local video on a mobile platform. Background technique [0002] Viewing multimedia files on mobile devices has become an increasingly popular public demand. However, in order to reduce the cost of storage and transmission, most multimedia files are compressed and encoded before being packaged and stored. To play these files, firstly, they need to be decapsulated and then decompressed. The decompression process generally has a relatively high computational complexity. If software is used to handle this process (in fact, the CPU is used to do complex decompression operations), it will be a test for the computing power of the CPU and the endurance of the battery. The hardware decoder has high decoding efficiency and power saving, so it...

AI Technical Summary

Problems solved by technology

[0004] First, before playing, the method of directly transcoding to generate a new file requires additional disk space and time, but for mobile devices with insufficient disk space, this method is not advisable

[0005] Second, directly calling the system hardware decoder is similar to a cracking method, which is to guess the calling interface of the system hardware decoder. This method has great technical difficulties, and it is even unsolvable on some mobile platforms.
