Embodiment 2

[0035] Compared with the method of multimedia decoding provided by Embodiment 1, step 104 is added after step 103: counting the time during which the frame rate decoded by the first decoder is less than the preset playback frame rate, if If the time is greater than the set first time threshold, switch to the second decoder to decode the multimedia file. Optionally, if the above condition is not met, cancel the preloading of the second decoder.

[0036]For example, the first time threshold is 30 seconds, following the example in Embodiment 1, if the frame rate decoded by the first decoder is less than 30 frames / second, and this state lasts for more than 30 seconds, switch to the second decoder for decoding, Otherwise the preloading of the second decoder is canceled.

Embodiment 3

[0037] Compared with the method of multimedia decoding provided by embodiment three, step 105 is added after step 103: since the frame rate decoded by the first decoder is less than the preset playback frame rate, if the decoded predetermined number of frames If the time consumed by the picture is greater than the set second time threshold, switch to the second decoder to decode the multimedia file; otherwise, optionally cancel the preloading of the second decoder. The second time threshold may be set as a quotient obtained by dividing the predetermined number of frames by the preset playback frame rate, or may be set as a value smaller than the quotient, which is not limited here.

[0038] For example, the predetermined number of frames is 600 frames, and the second time threshold is 20 seconds. Using the example in Embodiment 1, since the frame rate decoded by the first decoder is less than 30 frames / second, if decoding 600 frames consumes If the time is greater than 20 seco...

Abstract

The invention discloses a multimedia file decoding method, a multimedia player and playing equipment. The method comprises steps that a preset play frame rate of a to-be-decoded multimedia file is acquired; a first decoder is loaded to decode the multimedia file; a frame rate of the first decoder is monitored; if the frame rate of the first decoder is smaller than the preset play frame rate, a second decoder is pre-loaded. The method is advantaged in that multimedia decoding efficiency can be improved.

Description

technical field [0001] The present invention relates to the field of information technology, more specifically, to a method for decoding multimedia files, a multimedia player and a multimedia player. Background technique [0002] With the development and construction of Internet technology and the improvement of consumer demand, multimedia resources with high resolution are increasingly required in daily applications. In addition, there are differences in operating environments such as hardware systems, operating systems and their versions, resulting in a single Decoders cannot meet all decoding needs. Contents of the invention [0003] The purpose of the present invention is to provide a method for decoding multimedia files to improve decoding efficiency. [0004] According to a first aspect of the present invention, a method for decoding a multimedia file is provided, comprising the following steps: obtaining the preset playback frame rate of the multimedia file to be d...
