Problems solved by technology

[0005] After the player finishes playing the current video file, it will re-initialize the playback. At this time, the intuitive performance is that the player has a black screen, that is, the video file that the user wants to watch continuously is interrupted during the playback process and cannot be played. Realize seamless playback of multiple files
[0006] The above is an example of video file playback to illustrate the problems existing in the prior art. Of course, there is also the problem that seamless playback cannot be achieved for audio file playback.

[0148] The method of the second embodiment of the present invention includes:

[0149] Obtain the first and second media files with the same decoding parameters, the first media file has a first play time, the start play time is T11, the end play time is T12, and the first play time is between T12 and T11 Difference Δt1; the second media file has a second play time, the start play time is T21, the end play time is T22, the second play time is the difference Δt2 between T22 and T21; the first and second media The total playing time of the file is the third playing time, and the third playing time is the sum of the first playing time and the second playing time, wherein the playing order of the first media file is in the second media before the file;

[0150] According to the third play time and the first play time, the start play time of the second media file is set to: T21 plus Δt1, and the end play time of the second media file is set to: T22 plus Δt1;

Abstract

The invention provides a method and a device for handling file play and a player. The device comprises a parameter processing module used for acquiring the play information of at least two to-be-played files and sending the information to the player; a first acquiring module used for acquiring the first corresponding relation between each of the at least two to-be-played files and the time segment of the total play time and the time migration of each to-be-played file relative to the total play time; a first intercepting module used for intercepting the request of the player and for acquiring data; a first positioning module used for confirming the current played file corresponding to a first time according to the first corresponding relation; a first data reading module used for reading the data corresponding to a second time, namely, the difference between the first time and the first time migration, from the data zone of the current played file; and a first data transmitting module used for transmitting the read data to the player. The invention realizes seamless play.

Description

technical field [0001] The invention relates to the technical field of video file processing, in particular to a file playback processing method, device and player. Background technique [0002] When playing video with a player, for continuous video files (such as several episodes of a series, multiple parts of a movie, etc.), the user hopes that the video files with this property can be played continuously. [0003] In the prior art, generally, the user selects video files to be played continuously, adds them to the playlist, and the player plays them in order by itself. [0004] However, the inventors found in the process of implementing the embodiments of the present invention that at least the following problems exist in the prior art: [0005] After the player finishes playing the current video file, it will re-initialize the playback. At this time, the intuitive performance is that the player has a black screen, that is, the video file that the user wants to watch con...
