Embodiment Construction

[0046] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0047] The present invention finds the play list of the same group of multimedia files by the playback device at the beginning of playing the multimedia files, and regards all the multimedia files recorded in the play list as a large virtual audio-visual file. Video files to operate. When actually playing, referring to the play list created before, whenever the content of the first multimedia file is played, the second multimedia file is searched. Accordingly, the purpose of seamless playback can be achieved. Furthermore, after the first multimedia file is finished playing, by aligning the starting point of the second multimedia file with the signal boundary of the TV signal for playing, the goal of seamless playback and video-audio synchronization can...

Abstract

The invention relates to a method for the multimedia file gapless playback, which is applicable to continuously playing a plurality of multimedia files by a playing device. Firstly, a first multimedia file and a second multimedia file are pre-analyzed, so as to produce a play list. Then the multimedia files are played according to the play list. By adopting the method, the gapless playback of a plurality of multimedia files can be realized, and the watching continuity of the multimedia files can be enhanced.

Description

technical field [0001] The invention relates to multimedia file playing technology, in particular to a method for continuously playing multiple multimedia files and seamlessly playing. Background technique [0002] With people's demand for high-quality images, the amount of audio-visual data of the same length of time will become larger and larger. If the common audio and video interleaving (AVI, Audio Video Interleaved) format is used to store, since the file content of the AVI format has a size limit, the audio and video data content needs to be divided into multiple multimedia file segments for storage, which will cause the user to watch files containing When the same video of audio-visual data is used, different multimedia file segments of the video must be played multiple times, thus causing a bad experience to the user. [0003] The traditional multimedia file playing process is to play a selected single multimedia file, first parse the header file and index content o...
