Problems solved by technology

[0004] The main purpose of the present invention is to propose a video playback method and device, aiming to solve the following problems: when the source frame rate does not match the screen refresh rate, the terminal has to spend a lot of resources to coordinate the frame rate, which not only increases the The complexity of audio and video synchronization also causes a waste of resources such as network bandwidth and decoding capabilities

[0085] according to Figure 5 As shown, the third embodiment of the present invention provides a video playback device, the device includes:

[0086] The refresh rate obtaining module is used to obtain the screen refresh rate of the terminal device, that is, to obtain the screen refresh rate of the display device.

[0087] Through the refresh rate obtaining module, firstly, the terminal device is connected to the streaming media platform through the network, and then the streaming media platform uses the terminal device to obtain the current screen refresh rate of the display device.

[0088] The determining module is used to determine whether the frame rate of the film source to be played matches the screen refresh rate, that is, compares whether the frame rate of the film source to be played is equal to the screen refresh rate.

[0089] Through the determining module, it is compared whether the difference between the frame rate of the film source to be played and the screen...

Abstract

The invention discloses a video playing method and apparatus, computer equipment, and a computer readable medium. The method includes steps: obtaining a screen refreshing rate of a terminal device; determining whether a film source frame rate of a to-be-played film source is matched with the screen refreshing rate; if not, processing the film source frame rate of the to-be-played film source to generate a medium stream whose the film source frame rate and the screen refreshing rate are matched; and transmitting the medium stream to the terminal device. According to the video method and apparatus, frame loss or frame insertion operation is performed on the film source frame rate of the to-be-played film source in a streaming media platform, and the screen frame rate and the film source refreshing rate of the to-be-played film source are matched so that the frame rate of the output media data is reduced, the transmission code rate is reduced, the bandwidth requirement is reduced, each frame interval of the decoded medium stream is large, the media stream is output and displayed, and the waste of bandwidth resources, decoding resources of set top boxes, and CPU resources due to frameloss is avoided.

Description

technical field [0001] The present invention relates to the technical field of multimedia terminals, in particular to a video playing method, device, computer equipment and computer-readable medium, which completes the self-adaptive dynamic adjustment of data and business processes of media playing applications in real time through a streaming media protocol. Background technique [0002] With the development of the Internet, IPTV / OTT services are becoming more and more popular. Only unicast transmission solutions can be used in IPTV and OTT on-demand services. Even with the support of advanced video compression coding technologies such as HEVC, the transmission of 4K ultra-high-definition media streams It still becomes a contradiction with the limitation of network bandwidth. In order to reduce network bandwidth and improve user experience, various adaptive streaming media transmission technology layers are continuously launched. [0003] On the user terminal side, when th...
