The first image parameters may further include: the first code rate, which is not limited by this disclosure.

In some embodiments, after the video data is parsed to obtain the video parsing data, it is determined whether the first image parameter is valid according to a requirement of the video display module. If the first image parameter is valid, executing step S603; if the first image parameter is invalid, after the video analysis data is decoded to obtain a second image parameter, the video display module is initialized by using the second image parameter.

The embodiment of the present disclosure provides an implementation manner, when decoding video parsing data, it is not necessary to wait for all video frames to be decoded, and after obtaining a start frame in the video parsing data by decoding, a second image parameter corresponding to the start frame is obtained, where the start frame is an image corresponding to a start time of the video parsing data.

As shown in fig. 7, fig. 7 is a time axis schematic diagram of a video display method provided by the embodiment of the present disclosure, where the time T1 of parsing video data, the time T2 of initializing a video display module, and the starting time T3 of decoding video parsing data are shown in the diagram, a time length spent on initializing the video display module is T, the initialization of the video display module is completed at the time T4, and a decoding operation for the video parsing data is also completed at the time T4, so that the video display module can be controlled to display video decoding data at the time T4, and the initialization of the video display module is started in advance to complete the initialization before a first frame of the video decoding data is transmitted to the video display module, so that various display parameters of the video display module are adapted to the video decoding data, a video is played normally, and display abnormalities such as a splash screen, and a splash screen are avoided.

In some embodiments, step S604 may be replaced with the following steps S6041 to S6045, as shown in fig. 8, where fig. 8 is a second flowchart of a video display method provided by the embodiment of the disclosure:

and S6041, decoding the video analysis data to obtain a second image parameter.

Since the first image parameter is an image parameter set during video source encapsulation and may have a difference from an image parameter required for real video display, that is, a difference from a second image parameter obtained after decoding, in the embodiment of the present disclosure, under a condition that the first image parameter and the second image parameter are not matched, the second image parameter is used to reinitialize the video display module, so as to set the display parameter of the video display module to be matched with the video decoding data.

It should be noted that the second image parameter obtained after decoding the video parsing data is not completely different from the first image parameter, and in a normal case, the first image quality type in the first image parameter is different from the second image quality type in the second image, so that, when the video display module is reinitialized by using the second image parameter, the embodiment of the present disclosure reinitializes the video display module by using a part of parameters in the second image parameter that is different from the first image parameter. Compared with the prior art that all the second image parameters are used for initializing the display module, the time required by initialization is effectively reduced, and the video playing speed is further improved.

If the first image parameter is matched with the second image parameter, the initialization of the video display module is already completed by utilizing the first image parameter, and the video display module does not need to be initialized by utilizing the second image parameter. Therefore, the operation of initializing the video display module is advanced to the time before the decoding operation, and enough time is reserved for initializing the video display module, so that it can be understood that the video display module of the display device starts to initialize by using the first image parameter, and the decoding module starts to decode video analysis data, and the video display module can effectively ensure that the initialization is completed before the decoding module decodes to obtain a start frame and transmits the start frame to the video display module, and the video display module is ready to obtain the start frame for starting playing the video. The problem that display equipment is abnormal in display such as screen splash and screen flashing is avoided.

In a case where the first image parameter is matched with the second image parameter, after controlling the initialized video display module to display the video decoding data, an embodiment of the present disclosure provides an implementation manner, where identification information of the video data is determined, where the identification information includes a Uniform Resource Locator (URL) and/or a video name; and then the identification information and the first image parameter are correspondingly stored, so that the video display module is initialized by directly utilizing the first image parameter when the display equipment displays the video data next time, thereby further advancing the initialization operation and effectively shortening the video playing starting time.

In some embodiments, to ensure that the video is played normally, in the case that the decoded video parsing data obtains a start frame, an initialization flag is queried, where the initialization flag is used to indicate whether the initialization of the video display module is completed. And under the condition that the initialization flag bit indicates that the video display module is initialized completely, controlling the initialized video display module to display the video decoding data. The video display module is initialized by inquiring the initialization flag bit before the start frame is transmitted to the video display module, and video decoding data is transmitted to the video display module under the condition that the initialization of the video display module is determined to be completed, so that the display equipment can immediately display the start frame to normally play, the problem of abnormal video display caused by asynchronous transmission of the start frame and initialization of the video display module is avoided, and the video watching experience of a user is improved.

In summary, the present disclosure provides a video display method, in which video data is acquired and analyzed to obtain video analysis data and a first image parameter, a video display module is initialized according to the first image parameter, then the video analysis data is decoded to obtain video decoding data, and the initialized video display module is controlled to display the video decoding data, so that the first image parameter required by initialization is acquired before decoding, thereby accelerating the operation of initializing the video display module, shortening the video broadcast start time, and avoiding the problem of abnormal display such as screen splash and screen splash.

In addition, in the embodiment, the first image parameter or the second image parameter really used for initializing the display module and the identification information of the video data are stored, so that when the same video data corresponding to the identification information is played subsequently, the stored image parameters are directly utilized for initializing, the operation of initializing the video display module is further accelerated, and the viewing experience of a user is favorably improved.
