Embodiment 1

[0063] figure 1 It is a schematic flowchart of a method for switching video definition in Embodiment 1 of the present invention. see figure 1 , this embodiment provides a video definition switching method, including:

[0064] Obtain the switching instruction of the video bit rate, download and parse the switching video stream; locate the switching key frame of the switching video stream and its corresponding switching timestamp based on the delivery time of the switching instruction and the parsing result of the switching video stream; Decapsulation processing is performed to obtain the switching video buffer data; until the current video stream is played to the switching key frame, the switching video buffer data is retrieved and decoded and played from the switching key frame.

[0065] In the video definition switching method provided in this embodiment, when the user performs the switching operation of the video bit rate, the playback control layer of the video player wil...

Embodiment 2

[0082] see figure 1 and image 3 , this embodiment provides a video definition switching device, including:

[0083] A player 1 and a broadcast control layer 2 for controlling the playback operation of the player 1, wherein the player 1 includes a parsing module 11, a positioning search module 12, and a decapsulation module 13, and the broadcast control layer 2 includes an instruction acquisition module 21 and a control module twenty two;

[0084] The instruction acquisition module 21 is used to sense the operation gesture of the user, and acquire the switching instruction of the video bit rate;

[0085] The parsing module 11 is used for downloading and parsing the switching video stream according to the switching instruction;

[0086] The positioning and searching module 12 is used to locate the switching key frame of the switching video stream and its corresponding switching time stamp based on the issuing time of the switching instruction and the parsing result of the sw...

Abstract

The invention discloses a video definition switching method and device, which aims to realize seamless switching of video definition, so that the video playback will not be interrupted when switching the definition, and the viewing experience of users is improved. The method includes: acquiring a switching instruction of the video bit rate, downloading and parsing the switching video stream; based on the delivery time of the switching instruction and the parsing result of the switching video stream, locating the switching key frame of the switching video stream and its corresponding switching timestamp; Decapsulate the switching video stream to obtain the switching video buffer data; until the current video stream is played to the switching key frame, the switching video buffer data is retrieved and decoded and played from the switching key frame. The device includes the method mentioned in the above technical solution.

Description

technical field [0001] The present invention relates to the field of video technology, and in particular, to a method and device for switching video resolution. Background technique [0002] With the explosive growth of online video resources, people's demand for watching videos online is increasing. However, due to limited user bandwidth, experience and other reasons, a video will produce a variety of video sources, such as normal, high-definition and ultra-high-definition, users You can choose to play videos of different resolutions, and when the user changes videos of different resolutions, it can be called video resolution switching. [0003] In the prior art, when a video player performs definition switching, it usually stops the currently playing video first, then loads a video with a new definition and jumps to the video termination time to play, but this switching method causes video playback. The incoherence affects the user's viewing experience. SUMMARY OF THE I...
