Embodiment 1

[0060] Embodiment 1 of the present invention provides a method for playing a media file. It should be noted that the steps shown in the flow chart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although the steps shown in the flow chart Although a logical order is shown, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0061]The method embodiment provided in Embodiment 1 of the present application may be executed in a mobile terminal, a computer terminal, or a similar computing device. figure 1 A block diagram of a hardware structure of a computer terminal (or mobile device) for realizing a method for playing a media file is shown. Such as figure 1 As shown, the computer terminal 10 (or mobile device 10) may include one or more (shown by 102a, 102b, ..., 102n in the figure) processor 102 (the processor 102 may include but not limite...

Embodiment 2

[0096] The execution subject of Embodiment 1 of the present invention is a playback client, that is, a playback terminal. Embodiment 2 of the present invention provides a playback method for another media file. The execution subject is a playback server. The thermal value of the segment is used to obtain the thermal value distribution data of the playback segment, which is used to send to the designated playback terminal, so that the playback terminal adjusts the playback speed of the playback segment according to the thermal value distribution data, and plays the corresponding playback segment according to the playback speed.

[0097] In one embodiment, the server generates the thermal value of the playback segment according to at least one of the following thermal parameter information of the playback segment in the media file:

[0098] Dot marks for playback segments marked during media file editing;

[0099] Pre-collected user's emotional information when watching the broa...

Embodiment 3

[0105] Embodiment 3 of the present invention provides a method for playing a media file. Taking the video playback method as an example, refer to Figure 5 As shown, its specific implementation process may include the following steps:

[0106] Step S51: Obtain the pre-generated heat value distribution data of each playing segment of the video from the server.

[0107] It may be that, for a specified video, the server obtains at least one of the following pieces of information:

[0108] (1) Dot marks for each playback segment marked in the video editing process.

[0109] (2) Pre-collected user's emotional information when watching each broadcast segment.

[0110] (3) Screen change information of each playback segment.

[0111] (4) Audio change information of each playback segment.

[0112] The server generates heat value distribution data of each playback segment of the video according to at least one of the acquired information. After the heat value distribution data is g...

Abstract

The invention discloses a media file playing method, device and system. The playing method of the media file comprises the following steps: acquiring thermodynamic value distribution data of a playing segment in the media file; adjusting the playing speed of the playing segment according to a preset corresponding relation between the thermodynamic value and the playing speed and the thermodynamic value distribution data; and playing the corresponding playing segment according to the playing speed. The playing speed of each playing segment of the media file can be reasonably adjusted, automatic variable-speed playing of the media file is achieved, and the feeling degree of a user is improved.

Description

technical field [0001] The invention relates to the technical field of media files, in particular to a method, device and system for playing media files. Background technique [0002] In the prior art, the playback rate during video playback is basically fixed, and the user actively sets the playback speed. For example, 0.5, 0.8, 1, 1.25, 1.5, 2.0 and 3.0 are commonly used at present. Playing video at a fixed speed allows users to watch video content quickly or slowly, but the mode is relatively single, and the user experience is still not high, and automatic variable speed playback cannot be realized. Contents of the invention [0003] In view of the above problems, the present invention is proposed to provide a method, device and system for playing media files that overcome the above problems or at least partially solve the above problems. [0004] In a first aspect, the embodiment of the present invention provides a method for playing a media file, including: [0005...
