Detailed Description
Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus their detailed description will be omitted. Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale.
In the video synchronous playing technology, video synchronous playing between video playing devices such as televisions, computers, and mobile phones can adopt a plurality of modes, and the first video synchronous playing mode is as follows: the mode of adding the playing source is that a DVD player or a computer host is added, then audio and video lines are laid, and the playing content is transmitted to each video playing device, so that each device can play video synchronously.
The second video synchronous playing mode is as follows: the mode of adding the main server is that a main server is added to provide an access interface to transmit the video content currently played by the main server outwards, and the video playing device in the local area network where the main server is located acquires the video information currently played through the interface which is connected with the main server to realize synchronous playing of the video playing device and the main server.
The third video synchronous playing mode is as follows: the mode of using a certain video playing device as a playing host can be regarded as a simplified version of the second mode, and only a main server does not need to be added, one video playing device in a plurality of video playing devices is used as a center to send broadcast to inform other devices of synchronous playing, and the video synchronous playing mode has the same defects as the second playing mode, namely once the main playing device breaks down, the other devices cannot receive synchronous broadcast, the synchronous playing cannot be continued, and the video synchronous function fails.
Therefore, to overcome the disadvantages of the video synchronous playing method, the present disclosure provides a video playing method, which can implement decentralized video synchronous playing, and each playing.
The disclosed embodiment provides a video playing method, as shown in fig. 1, the video playing method is applied to each playing terminal in a playing terminal cluster, and the method includes:
s101: responding to the downloading instruction, downloading the video matched with the downloading instruction, and sending a downloading progress to other playing terminals;
s102: receiving the downloading progress of other playing terminals, playing the video according to the playing node corresponding to the downloading instruction after determining that the downloading between the playing terminal and the other playing terminals is finished, and sending the playing progress to the other playing terminals;
s103: and if the playing progress is asynchronous with the playing progress of other playing terminals, adjusting the playing progress to the target playing progress.
In step S101, in response to the download instruction, the video matched with the download instruction is downloaded, and the download progress is sent to other playback terminals.
Each playing terminal in the playing terminal cluster needs to establish a connection with the cloud platform, and in a general case, each playing terminal and the cloud platform establish a connection with an HTTPS (hypertext Transfer Protocol over secure transport Protocol) as a transmission Protocol.
The cloud platform may provide terminal registration for the playback terminals, and may manage each playback terminal, for example, the cloud platform may select the playback number of the playback terminals according to the needs of the user, or may set one or some of the multiple playback terminal devices as a white list or a black list, so as to facilitate management. The user can upload videos needing to be played synchronously to the cloud platform, the cloud platform can save and send the videos of the user, the cloud platform can issue the videos to the playing terminals and send different video clips to different playing terminals according to different video synchronization modes, wherein the video issuing of the cloud platform to the playing terminals can be achieved by simultaneously issuing one or more videos to different playing terminals or by issuing the videos to different playing terminals at different time points, and the video issuing time and the video issuing sequence of the cloud platform can be determined according to actual use requirements.
In the disclosure, the video synchronization mode of the playing terminal includes a video synchronization mode and a video splicing mode, where the video synchronization mode is that the selected playing terminal simultaneously plays the same video or the same part of the same video, and the playing terminal is ensured to play the same picture of the video; the video splicing mode is that each selected playing terminal plays a part of the same video, which can be the same segment or different segments, and the playing of each playing terminal is different segments in the same video, and the videos played by a plurality of different terminal devices in the same time period can form a complete video, but the synchronous playing of a plurality of playing terminals is also ensured, so that the continuity of video playing in the video splicing mode can be ensured.
The workflow of the cloud platform is described below with reference to fig. 2:
firstly, the cloud platform determines the number of devices in a playing terminal cluster according to the needs of a user, and determines a specific playing terminal;
secondly, the cloud platform determines a playing video according to video playing content required by a user;
thirdly, the cloud platform screens and cuts the video according to the video playing mode selected by the user: if the user selects a video splicing mode, cutting the selected video, and sending the cut video segments to different playing terminals according to the playing sequence; and if the user selects the video synchronization mode, directly transmitting the selected video to different playing terminals.
And finally, the cloud platform issues a downloading instruction to the playing terminal, and the playing terminal can download the video according to the setting of the playing terminal.
According to the work flow of the cloud platform, the uploading and downloading of videos can be flexibly realized through the management of the contents uploaded by the user and the playing terminal, and the use of the user is facilitated.
In step S102, the download progress of other playing terminals is received, and after it is determined that the download between the playing terminal and the other playing terminals is completed, the video is played according to the playing node corresponding to the download instruction, and the play progress is sent to the other playing terminals.
After the cloud platform issues the played video to the playing terminals, the playing terminals start downloading the video corresponding to the downloading instruction, because each playing terminal can be a device with different model, therefore, the video downloading speed of each playing terminal can also be different, thus the video downloading end time points of different playing terminals can also be different, in order to ensure that the subsequent playing start time is the same, it is required to ensure that the selected playing terminals can start playing the video after the downloading is finished, therefore, a plurality of selected playing terminals can be arranged in the same local area network, each playing terminal can carry out butt-joint communication with other playing terminals through an interface carried by the playing terminal, and in the process of downloading the video, each playing terminal can periodically send a User Datagram Protocol (UDP) broadcast to other playing terminals, the downloading progress is sent through broadcasting, each playing terminal can also receive and store the downloading progress sent by other playing terminals, the downloading progress of the playing terminal and the downloading progress of other playing terminals are comprehensively considered, if the downloading progress of the playing terminal is faster than that of other playing terminals, the next step of operation is stopped after the video is downloaded, the downloading of other playing terminals is waited until all the selected playing terminals are downloaded, the video is uniformly played according to the playing node information in the instruction sent by the cloud platform, and meanwhile, each selected playing terminal needs to send the video playing progress to other playing terminals.
In step S103, if the playing progress is not synchronous with the playing progress of other playing terminals, the playing progress is adjusted to the target playing progress.
In the process of video playing, each playing terminal periodically sends playing progress to other playing terminals, meanwhile, each playing terminal also receives the video playing progress of other playing terminals, a target playing progress is determined by combining the playing progress of the playing terminal with the playing progress of other playing terminals, the playing progress is uniformly adjusted to the target playing progress, the target playing progress can be the fastest playing progress in a plurality of playing terminals, the playing progress which a user wants to adjust can also be the playing progress, the target playing progress can be set according to actual needs, and the disclosure does not specifically limit the process.
When the playing progress of the playing terminal is adjusted, the system time of the playing terminal is adjusted, and the playing progress of the audio stream in the video of the playing terminal is adjusted.
The adjustment of the system time of the playing terminal comprises the following steps:
in fig. 3, S201: and in a preset interval time, sending the system time to other playing terminals, receiving the system time of other playing terminals, and performing weighted average calculation on the system time of the player and the system time of other playing terminals to obtain a weighted average value of the system time.
S202: and if the difference value of the weighted average value of the system time and the preset time reference value is within the preset range, determining the system time.
S203: and if the difference value of the weighted average value of the system time and the preset time reference value exceeds the preset range, adjusting the system time to be the preset reference time.
After the playing terminals start playing videos, each playing terminal sends own system time to other playing terminals within a preset time interval, because each terminal device is in the same local area network, each terminal device can send UDP broadcasts through the local area network, system time information is transmitted to a plurality of playing terminal devices, and meanwhile, each playing terminal can also receive and store the system time of other playing terminals.
The preset time interval may be 10 minutes, the smaller the preset time interval is, the smaller the error of the system time is, and of course, the preset time interval may also be less than 10 minutes, for example, 8 minutes, 6 minutes, 4 minutes, and the like, and although the smaller the preset time interval is, the smaller the error of the system time is, due to the shortening of the time interval, the calculation amount of the playing terminal for calculating the average weighted value of the system time may be increased, and the loading speed and the playing speed may be slowed down, and the like.
After the playing terminal receives the system time of other terminal equipment, the system time of the playing terminal and the system time of other playing terminals are weighted and averaged, the system time after weighted averaging is set as the existing system time, each playing terminal is guaranteed to have the same system time, meanwhile, a third-party linear time is taken as a reference value, namely a preset time reference value, for the terminal equipment cluster, and if the difference value of the existing system time and the preset time reference value is in a preset range, the playing terminal can keep the existing system time as the system time; if the difference between the current system time and the preset time reference value exceeds the preset range, the current system time of the playing terminal needs to be further adjusted to the preset reference time to ensure that all the playing terminals have the same system time, which is the basis for video synchronous playing.
The adjustment of the playing progress of the playing terminal comprises the following steps:
in fig. 4, S301: and determining the playing progress of the video stream in the video according to the playing progress of the audio stream in the video.
S302: and receiving the playing time stamps of the audio streams in the videos of other playing terminals within a preset interval time, and performing weighted average calculation on the playing time stamps and the audio stream playing time stamps to obtain a time stamp weighted average value.
S303: and if the difference value of the weighted average value of the time stamps and the reference value of the preset time stamps is within a preset range, determining the playing progress of the video.
S304: and if the difference value between the weighted average value of the time stamps and the reference value of the preset time stamps exceeds the preset range, adjusting the playing progress of the video to the target playing progress.
After the uniform playing time of the playing terminal is determined, the playing progress needs to be adjusted, the playing terminal can send the video playing progress of the playing terminal to other playing terminals within a preset time interval, and meanwhile, the video playing progress sent by other playing terminals can be received, wherein the video playing progress mainly refers to the playing progress of audio streams in videos, the playing terminal can receive audio stream timestamps sent by other playing terminals and audio stream timestamps of the playing terminal to perform weighted average calculation, the weighted average value is obtained, and the existing audio timestamps of the playing terminal are obtained.
The preset time interval may be set to be every m milliseconds, that is, every m seconds is taken as a time interval to periodically send the audio stream time stamp to other playing terminals, and in order to ensure that the video playing progress is kept synchronous, the preset time interval is not too long, so that the playing terminals can be kept updating the audio stream time stamp in real time, the audio stream time stamps of a plurality of playing terminals are kept the same, but in order to ensure the speed of calculating the weighted average value of the playing terminals, the preset time interval is not too short, and therefore, the preset time interval is set at the millisecond level.
After the playing terminal obtains the existing audio stream timestamp, the existing audio stream timestamp is compared with a preset audio stream timestamp, if the difference value between the existing timestamp and a preset timestamp reference value is within a preset range, the existing timestamp is determined to be used as the audio stream timestamp of the playing terminal, the playing progress of the video stream is adjusted to be synchronous with the playing progress of the audio stream, and the playing progress of the video can be determined; and if the difference value between the current timestamp and the preset timestamp reference value exceeds the preset range, adjusting the playing progress of the audio stream to the target playing progress, and simultaneously adjusting the playing progress of the video stream according to the playing progress of the audio stream, namely adjusting the playing progress of the video to the target playing progress.
The target playing progress can be the playing progress with the fastest playing progress in the video stream of the playing terminal, or the playing progress which is set by a user in a user-defined mode according to needs, the target playing progress can be defined according to actual needs, and the method is not specifically limited in the disclosure.
The following describes the playing flow of the playing terminal with reference to fig. 5 and 6:
the method comprises the steps that the playing terminals receive a downloading instruction sent by a cloud platform to start downloading videos, each playing terminal broadcasts video downloading progress to other playing terminals through a local area network, and if the video downloading of all the playing terminals is finished, the video playing is started;
after the playing terminal starts video playing, the playing terminal broadcasts video playing progress to other playing terminals through a local area network, wherein the broadcasted video playing progress comprises: the method comprises the steps that a playing terminal sends equipment system time to other playing terminals every n minutes, receives the system time of other playing terminal equipment, carries out weighted average calculation on the system time of the playing terminal and the system time of other playing terminals to obtain the system time, if the difference value between the obtained system time and preset time is within a certain range, the system time after weighted average calculation is determined to be the system time of the playing terminal, and if the difference value exceeds the preset range, the preset time is set to be the system time of the playing terminal, and the consistency of the system time of a plurality of playing terminals is kept;
meanwhile, the playing terminal sends audio playing progress to other playing terminals every m milliseconds and receives the audio playing progress sent by other playing terminals, the playing terminal performs weighted average calculation on the audio playing progress of the playing terminal and the audio playing progress of other playing terminals to obtain the audio playing progress, if the difference value between the obtained audio playing progress and the preset playing progress is within a preset range, the audio playing progress of the playing terminal is determined, if the difference value exceeds the preset range, the audio playing progress of the playing terminal is adjusted to the target preset audio playing progress, and the corresponding video playing progress can be automatically adjusted according to the audio playing progress; and after the playing progress is finished, the playing terminal finishes playing.
