The system clock may be a clock time of the target operating system, and the playing progress may represent a playing position of the video data in a screen corresponding to the target operating system, and specifically may be a played time of the video data.
Specifically, the system time of the target operating system may be extracted as a system clock, and the time length of the video data that has been played is determined according to the decoded video data, and the time length may be used as a playing progress.
And step 204, taking the system clock and the playing progress as synchronous playing information.
In the embodiment of the present invention, the acquired system clock and the acquired playing progress may be used as the synchronous playing information, and the synchronous playing information may be sent to other screens, may be sent through a general bus, or may be sent through a wireless network, for example, in a vehicle-mounted network, the synchronous playing information may be sent to other screens through a vehicle-mounted ethernet network. Furthermore, except for sending the system clock and the playing progress as synchronous playing information, the system clock and the playing progress can also be used as synchronous playing information for video playing parameters such as the playing speed of a video file or the decoding speed of the video file, and the like, so that accurate synchronous playing of each screen can be further realized.

In the embodiment of the invention, for each screen, the clock difference between the corresponding local clock and the system clock is determined, the clock difference is increased or decreased on the basis of the corresponding time of the playing progress, and the playing progress after the adjustment and compensation can be different because the time of the local clock of each screen is different.
And step 207, playing the video data in each screen according to the compensated playing progress.
Specifically, each screen determines the playing position of the video data according to the compensated playing progress, and displays the video data in the corresponding screen from the playing position.
According to the embodiment of the invention, when a multi-screen synchronous playing instruction is obtained, an operating system which is playing a video file is used as a target operating system, the target operating system is controlled to decode the video file to obtain video data and audio data, the playing progress of the video data and the system clock of the target operating system are determined, the playing progress and the system clock are used as synchronous playing information and are sent to operating systems of other screens by the target operating system, the operating systems of the screens respectively determine local clocks, the playing progress is compensated through the clock difference between the local clocks and the system clock, the video data are played in the screens according to the compensated playing progress, synchronous playing of videos of different screens is realized, accurate determination of the video progress is realized through synchronous playing information, the video playing synchronization rate is improved, and user experience can be improved.
Further, on the basis of the above embodiment of the present invention, the playing the video data in each of the screens according to the compensated playing progress includes: controlling each screen to adjust video data to the position of the playing progress in at least one mode of fast forward, fast backward and dragging progress bar; and respectively sending the audio data to the audio ports corresponding to the screens for output.
The audio port may be an output port of audio data, and may include a headphone, a speaker, and the like.
In the embodiment of the invention, after the playing progress is determined, the playing position corresponding to the playing progress of the video data can be controlled by adopting a mode of fast forward, fast backward or dragging the progress bar, so that the screens can be played at the same playing position. After the playing position of the video data is determined, the audio data at the playing position can be respectively sent to each audio port for output through an audio route. For example, the screen a corresponds to the audio port a, the screen B corresponds to the audio port B, and the audio data is respectively sent to the audio port a and the audio port B through the audio route for output.
Exemplarily, fig. 4 is an exemplary diagram of a video synchronous playing method provided by a second embodiment of the present invention, referring to fig. 4, a video player on a screen a is playing a video, a user triggers a multi-screen synchronous playing instruction by clicking a virtual key or an entity key on the screen a, the video player on the screen a normally decodes a video file, decodes the video to generate video data and audio data, determines operating system information such as a system clock and the like through an operating system of the screen a, determines playing information such as a decoding speed, a playing progress, a playing speed and the like through the video data, and takes the acquired operating system information and playing information as synchronous playing information. The video player of the screen A can send synchronous playing information to the video player of the screen B through the vehicle-mounted Ethernet, the video player of the screen B sends the synchronous playing information through the screen A, the video playing progress of the screen B is adjusted to be the same as that of the screen A on the premise that the video playing of the screen A is not influenced, the operating system information and the playing information of the screen A and the screen B in the synchronous playing information can be continuously judged in the adjusting process, then the playing progress of the screen B is adjusted, and therefore the synchronization of the playing progress is achieved. It can be understood that, in the synchronization process, the video played by the screen a is normally played, only the progress of the video played by the screen B is adjusted, after the screen B is adjusted, the audio data of the screen a can be transmitted to the sound output port corresponding to the screen a, and correspondingly, the audio data of the screen B is sent out through the sound port of the screen B. And when the playing progress of the screen A is changed, the screen B can reselect the synchronous video according to the changed playing progress of the screen A correspondingly, and before the synchronous function is released, the playing progress of the operation screen B can reversely control the playing progress of the screen A.
