Problems solved by technology

The disadvantage of this traditional method is that in the process of closing the original code stream and loading the new code stream, it will inevitably cause a short black screen on the playback page, and the whole process is executed serially, and the loading of the new code stream may It will cause freezes, and the probability of users waiting again will increase, so that the perception experience presented to app users is poor

Embodiment 1

[0030] figure 1 It is a flow chart of a method for seamless switching of video streams provided by Embodiment 1 of the present invention. figure 2 It is a flow chart of a video stream seamless switching method in a preferred implementation mode provided by Embodiment 1 of the present invention.

[0031] like figure 1 and figure 2 As shown, the video stream seamless switching method provided by the embodiment of the present invention includes the following steps:

[0032] 101. When playing an old video stream, according to a switching request of a new video stream, perform switching preparation and opening operations of a corresponding new video stream, where the switching preparation includes determining a switching condition of the new video stream.

[0033] Specifically, it is judged whether the switching request triggered by the user satisfies the switching conditions including whether the clarity is consistent and / or whether the session ID of the switching transmissio...

Embodiment 2

[0057] Figure 4 It is the video stream seamless switching device provided by Embodiment 2 of the present invention, such as Figure 4 As shown, the video stream seamless switching device provided by the embodiment of the present invention includes a switching preparation module 1 , an acquisition module 2 , a decoding module 3 and a switching module 4 .

[0058] Specifically, the switching preparation module 1 is used to: determine whether the switching request triggered by the user satisfies the switching conditions including whether the clarity is consistent and / or whether the session ID of the switching transmission is still valid; According to the switching request, prepare and open the switching of the corresponding new video stream. If not, the reason for the switching failure will be called back.

[0059] The switching preparation module 1 further includes a switching preparation module 11 and an opening operation module 12, and the switching preparation module 11 and...

Abstract

The invention discloses a video stream seamless switching method and device, and belongs to the technical field of real-time streaming media processing. The method includes the steps: performing switching preparation and an opening operation of a corresponding new video stream according to a switching request of a new video stream during the playing of an old video stream, wherein the switching preparation includes the steps: determining a switching condition of the new video stream; continuously obtaining the play related data of the old video stream and the new video stream after the new video stream is opened; resetting a decoder to obtain the media data of the new video stream; and performing the seamlessly switching at the corresponding switching time point of the new video stream. The method realizes more smooth and seamless switching. Compared with a conventional code stream cutting scheme, the method greatly improves the playing experience of a user, and is good in applicationprospect.

Description

technical field [0001] The invention relates to the technical field of streaming media real-time processing, in particular to a video stream seamless switching method and device. Background technique [0002] In current mainstream video app applications, seamless switching is mostly achieved by dual players. That is, the current player plays the code stream of the original definition. After the user clicks to switch, an additional player instance is launched in the background of the app to load the code stream of the new definition. During playback, the switching strategy (such as switching by frame number, current time point key frame switching), select the appropriate switching point to splice the two players, so as to achieve the effect of seamless switching. [0003] In the online video point live broadcast application, the streaming media server will push the media stream of the corresponding specification according to the app user's request. For example, the user requ...
