Embodiment Construction

[0025] The present invention reduces the total number of picture frames to be decoded without affecting the decoding of other picture frames by discarding non-reference picture frames, which helps to reduce the burden of video decoding and increase the decoding speed, thereby avoiding Video stuttering.

[0026] To further illustrate the present invention, the following examples are provided:

[0027] figure 1 A schematic flowchart of a video decoding method according to an embodiment of the present invention is shown.

[0028] Such as figure 1 As shown, the video decoding method according to one embodiment of the present invention is applied to a terminal device, including:

[0029] Step 102, monitoring the video decoding speed of the terminal device;

[0030] In this embodiment, the video decoding speed can directly reflect the decoding capability and actual decoding status of the terminal device; specifically, the video decoding speed can be determined by various means, ...

Abstract

The invention provides a video decoding method and device which are applied to terminal equipment. The video decoding method includes the steps that the video decoding speed of the terminal equipment is monitored; when the video decoding speed is smaller than a preset decoding speed, the type of a picture frame to be decoded at present is judged; if the picture frame to be decoded at present is a non-reference type picture frame, the picture frame to be decoded at present can be discarded. According to the technical scheme, the non-reference type picture frame is discarded, on the basis that other picture frames cannot be affected to be decoded, the total number of picture frames needing to be decoded is decreased, the video decoding method and device are conducive to lowering the video decoding burden, the decoding speed is increased, and therefore the video blocking phenomenon can be avoided.

Description

technical field [0001] The present invention relates to the technical field of video playback, in particular to a video decoding method and a video decoding device. Background technique [0002] With the continuous development of network technology, the data transmission speed of wired network and mobile communication network is getting faster and faster, so that in the process of video playback, the video decoding capability of the device has become a major bottleneck affecting the quality of video playback. When the video decoding capability of the device is weak, it will directly reflect that the video playback process freezes, affecting the viewer's experience. Contents of the invention [0003] In view of this, the present invention provides a video decoding method and a video decoding device, which can reduce the total number of picture frames to be decoded without affecting video playback, help reduce the burden of video decoding, and improve decoding speed to avoi...
