Abstract

The present invention relates to the field of video playing. Disclosed are a method and apparatus for switching video definitions, which is invented to resolve the problem of playing smoothness of video playing affected during the switching of definitions. The method in the present invention comprises: during the playing of a first video source, determining, according to current network condition, whether a video definition is to be switched; if the video definition is switched, establishing a second decoding library according to the video definition, and loading, by means of the second decoding library, a second video source having a definition level corresponding to a current network speed; and seamlessly switching the first video source to the second video source. The seamless switching from the first video source to the second video source can be implemented by means of corresponding conversions of transparencies. The present invention is mainly used in a process of switching definitions of online videos.

Description

technical field [0001] The invention relates to the field of video playback, in particular to a method and device for switching video definition. Background technique [0002] At present, major video sites will provide videos with different resolutions for online videos, and the more common resolution levels include "standard definition", "high definition", "ultra definition" and so on. When users watch online videos through the web player of the browser or the native player of the APP client, they can choose the appropriate definition level according to network conditions and personal needs. Usually, when the network bandwidth is not limited, the user generally prefers to watch videos with higher definition, and when the network bandwidth cannot support the current definition level, the user needs to lower the video definition level. [0003] In the prior art, switching of video definition is mainly done through manual operation. The user clicks the "sharpness" control in ...
