As shown in fig. 1, fig. 1 is a flowchart of a video synchronization method according to an embodiment of the present disclosure, which includes the following steps.
S100, acquiring information of a video file to be played, and directly or indirectly sending the information to at least one receiving terminal to enable the at least one receiving terminal to play the video file.
Specifically, in the embodiment of the present disclosure, the video file may be stored in a server or a local (sending end), and accordingly, the video file may be obtained by, for example, reading from the server or directly opening from the local. After the video file is obtained or read, the video file can be shared. For example, when a video file is stored locally, the video file may be transmitted to one or more receiving terminals, specifically, the video file may be subjected to audio/video stream separation, the audio stream and the video stream are encoded at a transmitting terminal to form audio data and video data, and then the video data and the audio data are transmitted to the receiving terminals respectively or are transferred to the receiving terminals via a server. The audio data may include an audio clock, where the audio clock refers to a clock corresponding to an audio stream, and is used to represent a rate of the audio stream and control playing of the audio stream; the video data may include a video clock, which refers to a clock corresponding to the video stream, and is used to indicate the rate of the video stream and control the playing of the video stream. The audio clock and the video clock may also be referred to as timestamps. When a video file is stored in the server, the location information of the video file may be shared, for example, through the application app or the sharing address link url. It should be emphasized that the direct sending may be, for example, transmitting data information in a point-to-point streaming (streaming) manner, for example, a sending end streams video frames to other receiving ends, so that screens of other receiving ends synchronously display video images played by the sending end; the indirect sending may be, for example, data information transmitted by a server, for example, a sending end first uploads a data packet to the server, and the server sends the data packet to other receiving ends according to a destination address in the data packet; and other receiving ends can play the video file after receiving the video file.
S200, playing the video file and acquiring the playing progress information of the video file.
Specifically, when a video file is stored locally and other receiving terminals also store the video file, real-time information of video playing of the sending terminal, such as a time stamp of the video information or a time stamp of the audio information, may be obtained to determine the playing progress of the video file of the sending terminal. When the video file is stored on the server, the playing progress of the video file can be uniquely determined by acquiring the coordinates of the time axis of the playing video.
S300, the playing progress information is directly or indirectly synchronized to the at least one receiving terminal, so that the playing progress information is unified by the at least one receiving terminal.
Specifically, in the embodiment of the present disclosure, when the video file is locally stored, the timestamp may be sent to other receiving ends, so that the purpose of synchronous playing is achieved in a manner that the timestamps are aligned. In another embodiment of the present disclosure, the playing progress can be unified in a manner of synchronizing coordinates, that is, the playing time can be unified, and the positioning can be performed according to the time axis coordinates obtained as described above. In addition, the video images can be pushed in a point-to-point streaming manner, and at this time, because the pushed video image frames are video image frames played by the current sending end, a uniform playing progress is achieved between the sending end and at least one receiving end. It can be understood that, when the playing progress information is sent, the playing progress information may still be in a direct or indirect manner as described above, and details are not described here.
In particular, during the process of synchronous video playing, the sending end may adjust the playing progress, such as fast forward, fast backward, pause, etc. At this time, each receiving end also needs to correspondingly adjust the playing progress according to the received playing progress information, so as to synchronize the playing among the sending end, the receiving end and each receiving end. Specifically, when it is detected that the parameter received by the receiving end has a difference with the real-time playing progress, the playing progress of the receiving end is adjusted according to the received playing progress information. For example, after receiving a fast forward instruction, a jump operation may be performed, that is, skipping over the video image frame in the middle segment and directly jumping to the video image frame located at the sending end according to the parameters; or it is also possible to perform a double speed play operation, i.e., shorten the play time of each frame and the interval time between frames. For another example, after receiving the pause instruction, the playing of the video stream and the audio stream is synchronously stopped, that is, the time stamps of the corresponding video data and audio data are fixed. In the above manner, only the instruction of video progress adjustment can be transmitted, video image frames do not need to be transmitted, image quality compression in transmission does not exist, and occupied bandwidth is small, so that the advantages of clear image quality, smooth playing, good real-time performance and the like can be obtained in the embodiment of the disclosure. In addition, embodiments of the present disclosure may also include other synchronization operations, which are not specifically limited herein.
In addition, in addition to synchronizing the play progress, embodiments of the present disclosure may also include synchronizing video editing operations. As shown in fig. 2, fig. 2 is a flowchart of a video synchronization method according to another embodiment of the present disclosure.
S401, editing the video file in playing.
S402, acquiring the editing information, and directly or indirectly synchronizing the editing information to at least one receiving terminal, so that the at least one receiving terminal uniformly executes editing operation according to the editing information.
Specifically, acquiring contact track information generated by adding pictures on video image frames of the video file; and/or acquiring visual element information characters added on a video image frame of the video file and the adding positions of the visual element information; and/or obtaining progressive dummy degradation information for tone scale details of at least a portion of video image frames of the video file. More specifically, for example, if a sending end user performs a circling operation to define a certain area of a video image frame, the starting coordinates (x, y) of the circling operation are obtained, and then the path of the circling operation is synchronously obtained, specifically, a continuous coordinate set (x, y) is obtained1,y1)，(x2,y2)……(xn,yn) And synchronizing the continuous coordinate set to other coordinate sets directly or indirectlyAnd the receiving ends enable the corresponding positions of the corresponding video image frames of other receiving ends to repeat the coordinate forming path so as to present the same circled area. Specifically, the sending end receives the first operation, and locates the coordinate (x)1,y1) The coordinate can be marked as the point A, and the coordinate is sent to other receiving ends at the same time; other receiving ends obtain the coordinate, and the A' point at the same position is positioned according to the coordinate; similarly, the second operation is, for example, positioned at (x)2,y2) If the point is marked as point B, then a straight line from the point A to the point B can be arranged at the transmitting end; correspondingly, the same straight line from the point A 'to the point B' is repeated at the receiving end; it will be appreciated that the above operations may continue to locate C, D and more points, and that the lines formed by these points may be organized into a pattern or text to present various effects. For another example, when the sending-end user performs a mosaic operation, the position information of the mosaic may be first obtained as described above, and after the position information is obtained, the details of the color level of the video image frame in the region are degraded to cause a disturbing effect of the color block. The information of the demarcated area and the information of the color gradation detail deterioration are packaged and sent to other receiving terminals, or the information of the demarcated area, the information of the color gradation detail deterioration and the address information of the destination terminal are sent out through a server, so that the receiving terminals can display the mosaic effect together. In the embodiment of the present disclosure, the editing operation includes adding a drawing, such as graffiti, adding a text, such as a label, adding a subtitle, and the like, to the video image frame, which may be performed separately or together, and is not limited herein.
In the embodiment of the present disclosure, the sending end may be a control end, that is, an authority tag may be set at the sending end, and the synchronization instruction is sent based on the authority tag, and the other ends without the authority tag are receiving ends, and perform corresponding operations according to the synchronization instruction. It is understood that the permission label can be transferred, as shown in fig. 3, and fig. 3 is a flowchart of a video synchronization method according to another embodiment of the disclosure, including the following steps:
s501, setting an authority label, and sending the playing progress information according to the authority label.
S502, transferring the authority label to a first receiving terminal of the at least one receiving terminal, so that the first receiving terminal sends the playing progress information according to the authority label.
S503, receiving the playing progress information, and synchronizing the playing progress according to the playing progress information.
Specifically, the authority of the sending end is determined at first, and an authority tag is set, so that the sending end can control synchronous operation. And after the authority label is transferred from the sending end to one of the receiving ends, the control end is correspondingly changed from the sending end to the receiving end, at this time, the original sending end does not have the control authority any more, and the control authority is transferred to the receiving end along with the authority label, namely, the receiving end is considered as a new control end, and synchronous playing and control are controlled by the receiving end for receiving the authority label, including instruction sending, reference for synchronization and the like. The transfer of the authority label in the embodiment of the present disclosure is not particularly limited, and may be automatically specified by the control end. The issue of the operation instruction of the new control end and the synchronization of other ends after the permission label transfer are as described above, and are not described herein again.
In another embodiment of the present disclosure, the sending end and the receiving ends may be connected in communication while playing synchronously. As shown in fig. 4, fig. 4 is a flowchart of a video synchronization method according to still another embodiment of the present disclosure, which includes the following steps.
S601, playing the video file in the first window.
S602, a call connection with the at least one receiving end is created in a second window.
Specifically, a video file may be played through a first window and a call connection, such as a chat interface, may be displayed through a second window. More specifically, synchronized video file playback may be as previously described; the call connection can take many forms such as text, voice, video chat, etc. Similarly, the push of the content of the second window may also be direct or indirect. For example, the text chat interface (second window) can be directly transmitted to other receiving terminals in a streaming manner, or indirectly transmitted to other receiving terminals through the server; if the chat is a video chat, the encoded video image frame may be pushed to be directly or indirectly transmitted, and the specific manner is as described above, and is not described here again.
The first window and the second window may be arranged in various ways, for example, the first window and the second window may be located in the same display layer, for example, tiled non-overlapping display, as shown in fig. 5, and the first window and the second window are displayed side by side in the display area. It can be understood that the size relationship of the first window and the second window may be the same or different, the tiled arrangement is not limited to being displayed side by side, and the first window and the second window may have different arrangements. In addition, the first window and the second window may also be located on different display layers, as shown in fig. 6, the second window may be suspended above the first window, and it can be understood that, in order to not block the video playing, the area of the second window is smaller than the area of the first window at this time, and the position of the second window is not limited to the upper right corner of the first window, and other overlapping position relationships may also be included in the embodiments of the present disclosure.
The video synchronization method provided by the disclosure can at least realize the synchronous playing of the same video file at multiple ends, and can support the playing operation and editing of the video file at the multiple ends according to one end, and the communication connection is carried out while the video file is played, so that the use efficiency and the use experience of a user are improved.
The embodiment of the present disclosure further provides a device for video synchronization, which may be a sending end, for example. As shown in fig. 7, the apparatus 10 includes an acquisition module 101, a transmission module 103, and a play module 105. The obtaining module 101 may be configured to obtain information of a video file to be played and playing progress information of the video file. The sending module 103 may be configured to send the information and the playing progress information. The play module 105 may be used to play the video file.
As shown in fig. 8, an embodiment of the present disclosure further provides an apparatus for video synchronization. The difference between the present embodiment and the previous embodiment is that the apparatus 20 of the present embodiment further includes an editing module 207 and a setting module 209. The editing module 207 may be configured to edit the video file being played. The setting module 209 may be used to set the permission label. It can be understood that the newly added modules may be added simultaneously or separately, and only need to exert their functions, and the embodiments of the present disclosure are not particularly limited.
As shown in fig. 9, the embodiment of the present disclosure further provides a device for video synchronization, which may be a receiving end, for example. As shown in fig. 9, the apparatus 30 includes a receiving module 302, a playing module 304, and a synchronizing module 306. The receiving module 302 may be configured to receive information of a video file to be played and playing progress information of the video file. The playing module 304 may be configured to play the video file according to the information. The synchronization module 306 may be configured to synchronize the playing progress of the video file according to the playing progress information.
