Technical Field

The invention belongs to the technical field of players, relates to an optimization method and an optimization system, and particularly relates to an optimization method and an optimization system for switching player channels, a storage medium and a player.

Background

The player is used as a final presentation end of the video stream, and many companies are currently developing the player. The players in the market are not good and bad, and besides smooth playing, another very important standard for judging the quality of one player is the speed of switching channels. The player with slow channel switching speed gives users a bad experience, and directly causes the users to suspect that the video stream has problems, but the player is not well processed when the player processes the channel switching.

Therefore, how to provide an optimization method, a system, a storage medium and a player for switching a player channel to solve the delay feeling often occurring when the existing player switches a channel, and the defect of obvious improvement on playing H L S video stream, etc., has become a technical problem to be solved by those skilled in the art.

Disclosure of Invention

In view of the above drawbacks of the prior art, an object of the present invention is to provide a method, a system, a storage medium, and a player for optimizing player channel switching, which are used to solve the problem that playing an H L S video stream is obviously changed due to the delay often occurring when the existing player switches channels.

To achieve the above and other related objects, an aspect of the present invention provides a method for optimizing channel switching of a player, including: creating a singleton player object; calling a preset video stream parameter setting function to set parameter information of the video stream; and when the first frame played by the video stream is analyzed to be the instant decoding refresh frame, outputting a starting instruction for starting a player to start the player to play the video stream.

In an embodiment of the present invention, before the step of creating the singleton player object, the step of creating the singleton player object further includes: judging whether a singleton player object in the player is empty or not; if yes, switching to the step of creating a singleton player object; and if not, reconstructing the singleton player object.

In an embodiment of the present invention, the step of creating the singleton player object further includes: and when the player is detected to switch channels, multiplexing the created singleton player object.

In an embodiment of the present invention, after the step of multiplexing the singleton player object, the method for optimizing player channel switching further includes: initializing the singleton player object and changing the attribute information of the singleton player object.

In an embodiment of the present invention, the step of calling the preset video stream parameter setting function further includes: and enabling the preset video stream parameter setting function to replace an information analysis function of an audio and video conversion tool of the player.

In an embodiment of the present invention, the parameter information of the video stream is added to a list file for storing audio and video blocks.

In an embodiment of the present invention, the parameter information of the video stream includes a bandwidth, an imaging limit resolution, an encoding format, an audio format, a video height, a video width, and/or an average frame rate.

Another aspect of the present invention provides an optimization system for switching channels of a player, including: the creating module is used for creating a singleton player object; the parameter information setting module is used for calling a preset video stream parameter setting function so as to set the parameter information of the video stream; and the starting module is used for outputting a starting instruction for starting a player to start the player to play the video stream when the first frame played by the video stream is analyzed to be the instant decoding refresh frame.

Yet another aspect of the present invention provides a storage medium having stored thereon a computer program which, when executed by a processor, implements the method for optimizing a channel change of a player.

A final aspect of the invention provides a player comprising: a processor and a memory; the memory is used for storing computer programs, and the processor is used for executing the computer programs stored by the memory so as to enable the player to execute the optimization method for switching the player channels.

As described above, the optimization method, system, storage medium and player for switching player channels according to the present invention have the following advantages:

the optimization method, the optimization system, the storage medium and the player solve the problem of delay feeling of the player frequently occurring when the player switches channels, obviously improve the playing of the H L S video stream, enable a user not to have delay feeling when the user switches channels, and improve the use degree of the user.
