specific Embodiment 1
[0049] In the specific embodiment one, the method for realizing fast response in the multimedia file control process includes the following steps:
[0050] Step 1, the user selects a multimedia file, and the player takes the multimedia file as an operation target;
[0051] Step 2, the player creates a logic control thread, and executes the initialization process of opening the multimedia file;
[0052] Specifically, in the initialization process, a file channel needs to be opened to analyze the format, type, size, duration and other information of the file; in the initialization process, it is also necessary to perform initialization steps in routine operations such as dynamically loading the decoding library, which will not be described in detail here .
[0053] Step 3, create an index creation thread in the initialization process, start the index creation thread to create the playback time index of the multimedia file; the index creation thread and the logic control thread ...
specific Embodiment 2
[0058] In the second specific embodiment, the method for realizing fast response in the multimedia file control process includes the following steps:
[0059] Step 1, the user selects a multimedia file, and the player takes the multimedia file as an operation target;
[0060] Step 2, the player creates a logic control thread, and executes the initialization process of opening the multimedia file;
[0061] Specifically, in the initialization process, a file channel needs to be opened to analyze the format, type, size, duration and other information of the file; in the initialization process, it is also necessary to perform initialization steps in routine operations such as dynamically loading the decoding library, which will not be described in detail here .
[0062] Step 3, according to the audio and / or video type of the parsed file, choose to load the corresponding audio and / or video decodinglibrary, and create a media output thread; so far, the initialization process is co...

Abstract
The invention provides a method for realizing quick response in a multimedia file control process and a play device. The play device comprises a logic control module and a multimedia file resolving module, wherein the logic control module is used for controlling the multimedia file resolving module to create a multimedia file play time index in a parallel mode at the same time of opening a multimedia file; and the multimedia file resolving module is used for creating the multimedia file play time index under the control of the logic control module. Compared with the prior art which adopts a serial mode, the method adopts the parallel processing mode, which finishes the creation of the multimedia file play time index on the premise of not influencing the operational process of opening the file or repositioning the file, quickly opens and repositions the multimedia file, and particularly terminal equipment having relatively lower capacity of a processor, such as a mobile phone, a portable multimedia player and the like, can quickly respond to the file opening operation or the multimedia file repositioning operation of a user.
Description
technical field [0001] The present invention relates to multimedia data processing technology, more specifically, to a method and a playback device for realizing fast response in the process of multimedia file control. Background technique [0002] With the development of electronic technology and software technology, multimedia information technology has penetrated into all aspects of daily life. At the same time, users' requirements for multimedia information experience are also increasing. Multimedia playback devices are gradually changing from large to small, and from household to portable. Small multimedia playback devices such as MP3, MP4, and mobile phones have largely replaced traditional large multimedia devices for household use. However, the computing capability and data processing capability of portable playback devices are relatively limited. When opening or relocating (that is, re-determining the playback start time point during file playback) some larger multi...
