The multi-channel video synchronization method provided by the embodiment of the present application will be described in detail below with reference to fig. 1 to 5.
Fig. 1 is a schematic flowchart of a multi-channel video synchronization method according to an embodiment of the present disclosure.
As shown in fig. 1, the method of the embodiment of the present application may include the steps of:
s101, monitoring the playing state of each path of video in a plurality of paths of videos;
the multi-channel video refers to a plurality of independent videos which are displayed on the same display screen and collected back through different cameras, and the independent videos can be unrelated to each other in content: the method is characterized by comprising the following steps of (1) acquiring and forming by different cameras under different environments (for example, acquiring one video in a bookstore and a movie hall); also in relation to each other: the method is characterized in that the method is obtained by acquiring different target objects by cameras from different angles in the same environment (for example, acquiring one video for a host, a file presentation and participants in a conference room). Each of the multiple correlated videos corresponds in time, space and content. The embodiments provided in the present application all take the correlated multi-channel video as an example for explanation.
The video playing has a plurality of playing states such as fast forward, pause, reverse, double speed and the like according to the change speed of the progress bar; monitoring is monitoring, and is used for timely knowing whether the playing state of each path of video changes, and the monitoring of the playing state of each path of video in the multi-path video can be real-time monitoring or periodic monitoring (for example, monitoring once every 5s or monitoring once every 8 s).
S102, when the change of the playing state of a first path of video in the multi-path video is monitored, the playing state of the changed first path of video is confirmed;
the user can change the playing state of each path of video in the multiple paths of videos displayed on the same screen through touch operation, and the touch operation aiming at each path of video is mutually independent and does not interfere with each other. For example, under the condition that each path of video in the multiple paths of videos is played normally, the user pulls the progress bar of the first path of video backward through the touch display screen, so that the playing state of the first path of video is changed from normal playing to backward, and the playing states of other paths of videos are not interfered/influenced and are still played normally.
In order to realize the synchronous playing of multiple paths of videos, the playing state of each path of video in the multiple paths of videos needs to be monitored. When it is monitored that the playing state of a certain path of video in the multiple paths of videos changes, the path of video is defined as a first path of video, the playing state of the changed path of video is determined, and step S103 is executed.
The change of the playing state can be, for example, changing from a normal playing state to a pause state, changing from a triple playing speed to a double playing speed, and the like.
S103, based on the changed playing state of the first path of video, the playing state of a second path of video in the multiple paths of video is synchronously adjusted.
In the embodiment of the application, the multiple paths of videos are multiple independent videos which are mutually associated, and synchronous playing is required to achieve the correspondence of each video in time, space and content. Therefore, in the case that the playing state of the first path of video changes, the playing states of the other paths of video should be changed accordingly.
The synchronous adjustment of the playing state of the second path of video in the multi-path video means that the current playing state of the second path of video is controlled to be changed to be consistent with the changed playing state of the first path of video, and the two paths of video keep the same playing progress so as to realize synchronization.
It should be noted that two mutually independent videos may form two paths of videos, and five mutually independent videos may form five paths of videos, where the number of the multiple paths of videos in this embodiment is not limited in this application, and when it is monitored that the playing state of a certain path of video in the multiple paths of videos changes, based on the changed playing state of the path of video, the playing states of the other paths of videos in the multiple paths of videos are synchronously adjusted, including adjusting the playing states of the second path of video and the third path of video …, i.e., the nth path of video.
In the embodiment of the application, a terminal monitors the playing state of each path of video in a plurality of paths of videos, when the playing state of a first path of video in the plurality of paths of videos is monitored to be changed, the playing state of the first path of video after being changed is confirmed, and based on the playing state of the first path of video after being changed, the playing state of a second path of video in the plurality of paths of videos is synchronously adjusted. In the implementation mode, under the condition that the playing state of a first path of video in the multiple paths of videos changes, the playing states of the other paths of videos are changed through control, so that the playing states of the other paths of videos are consistent with the changed playing state of the first path of video, each path of video keeps the same playing progress, and the videos respectively correspond to each other in time, space and content, and therefore synchronous playing is achieved. By applying the embodiment of the application, synchronous playing can be realized without operating the playing progress of each path of video in multiple paths of videos one by one, and the operation is simple and convenient.
Fig. 2 is a schematic flowchart of a multi-channel video synchronization method according to an embodiment of the present disclosure.
As shown in fig. 2, the method of the embodiment of the present application may include the steps of:
s201, monitoring the playing state of each path of video in the multiple paths of videos;
this step can be referred to as S101, and is not described herein.
S202, when the playing states of at least two paths of videos in the multi-path videos are monitored to change, a timestamp of the change of the playing states of the at least two paths of videos is confirmed;
the user can change the playing states of different paths of videos displayed on the same screen through touch operation. For example, different paths of videos are operated by two hands in a "synchronous" mode, or the playing state of the non-target path of videos changes along with the playing state of the target path of videos at the same time due to mistaken collision, and the like.
The playing states of the videos in different paths change at the same time, and the changes can be the same change or different changes. For example, the left hand touches the playing state of the first path of video to reverse, and the right hand touches the playing state of the second path of video to fast forward; and due to the false collision, the playing state of the third path of video (non-target path video) changes to pause and the like along with the playing state of the fourth path of video (target path video).
The above examples are macroscopic "simultaneous" and "synchronous", and each operation actually has a sequence.
The playing state of each video in the multiple videos needs to be monitored, when it is monitored that the playing states of at least two videos in the multiple videos are changed simultaneously, the timestamp of the change of the playing states of the at least two videos needs to be confirmed, and then step S203 is executed.
The time stamp is a group of random numbers generated according to the system time and used for determining the time when the playing state of each path of video changes.
S203, taking the video with the time indicated first in the timestamp as a first video, and confirming the playing state of the first video after the change;
in the embodiment of the application, the multiple paths of videos are multiple independent videos which are mutually associated, and synchronous playing is required to achieve the correspondence of each video in time, space and content. Therefore, when the playing status of a certain path of video changes, the playing status of the other paths of video should also change accordingly.
When the playing states of at least two paths of videos in the multiple paths of videos change, in order to realize synchronous playing, the playing states of other paths of videos need to be synchronously adjusted by taking the playing state of one path of videos after changing as a reference.
According to the embodiment of the application, the synchronous adjustment reference of the playing state is determined according to the time sequence. Specifically, the timestamp is converted into time, a video path indicated by the first time (i.e., the video path with the first changed playing state) is defined as a first video path according to the time sequence, the playing state of the video path after the change is determined, and step S204 is executed.
S204, outputting first prompt information whether to perform synchronous playing;
when the playing state of at least one video in the multiple videos changes, whether the playing states of the other videos need to be synchronously adjusted depends on the situation, and therefore, after the playing state of the first video after changing is determined, whether the multiple videos need to be synchronously played needs to be determined.
The first prompt information is used to confirm whether to perform synchronous playing on multiple channels of videos, the confirmation mode may be to output a prompt whether to perform synchronous playing in a text form, and the prompt information may be, for example: question-whether to do synchronized play? Option-yes, no; and a prompt of whether synchronous playing is carried out or not can be output in a voice mode, and whether synchronous playing is required or not is confirmed according to voice feedback of a user.
The specific process of outputting the first prompt information to the user in the form of characters is as follows: popping up a prompt box/column on a display interface, selecting yes or no input by a user according to prompt information in the prompt box, and when the user inputs negative operation according to first prompt information, synchronously adjusting the playing states of other paths of videos in the multiple paths of videos by the terminal; when the user inputs a determination operation for the first prompt information, step S205 is executed.
The prompt box/column can be displayed on the screen in any dynamic/static display mode, and the prompt box/column bearing prompt information can be in other shapes.
S205, based on the determination operation input aiming at the first prompt information and the changed playing state of the first path of video, synchronously adjusting the playing state of a second path of video in the multiple paths of video.
The multi-channel video which is mutually associated should reach the correspondence of each video in time, space and content when playing synchronously. Therefore, after confirming the reference for synchronously adjusting the playing states of the multiple paths of videos, the terminal changes the synchronous adjustment of the playing states of the other paths of videos of the multiple paths of videos according to the reference based on the determination operation input by the user for the first prompt message.
The synchronous adjustment of the playing state of the second path of video in the multi-path video means that the current playing state of the second path of video is controlled to be changed to be consistent with the changed playing state of the first path of video, and the two paths of video keep the same playing progress so as to realize synchronization.
It should be noted that the number of the multiple paths of videos in the embodiment of the present application is not limited, and the multiple paths of videos may be three paths of videos, six paths of videos, or the like. When the playing states of at least two paths of videos in the multi-path videos are monitored to change, the synchronous playing adjustment reference of the multi-path videos needs to be confirmed, a first path of video is defined, and the playing states of the other paths of videos in the multi-path videos are adjusted synchronously according to the reference. The adjustment of the other paths of videos comprises adjustment of the playing states of the second path of videos and the third path of videos ….
Please refer to fig. 3-4, which are schematic diagrams illustrating a multi-channel video synchronization process according to an embodiment of the present disclosure.
The multi-path video shown in fig. 3-4 is a basketball event commentary video, and the commentary is synchronized with the event. The video is two paths of videos, and one path of video displayed on the left side of the screen is collected and formed for basketball players on a basketball court and is defined as a racing court video; one path of video displayed on the right side of the screen is formed by aiming at the collection of an instructor in a studio and is defined as an explanation video; the left and right videos are independent from each other and do not interfere with each other.
In the process of video production, if a clipping person wants to know the field situation and the corresponding explanation at a certain moment, the field video and the explanation video need to be played synchronously: for example, a progress bar below the field video is dragged to enable the video to fast forward to a target moment (as shown in a position shown by a dotted line in fig. 3), at this time, the terminal monitors that the playing state of one of the two videos (namely, the field video) changes, and pops up an information prompt box on the display screen: whether synchronous playing is to be performed or not (as shown in fig. 4), the clipping personnel makes a determination selection according to the content in the prompt box (i.e. selecting yes), the terminal synchronously adjusts the playing state of the other path of video (i.e. the commentary video) based on the determination operation, controls the commentary video to fast forward to the target moment, and the two paths of video realize synchronous playing.
The terminal in this embodiment includes, but is not limited to, a tablet computer, a palm computer, a Personal Digital Assistant (PAD), an interactive smart tablet, a mobile phone, and other devices.
In the embodiment of the application, a terminal monitors the playing state of each path of video in a plurality of paths of videos, when the playing state of a first path of video in the plurality of paths of videos is monitored to be changed, the playing state of the first path of video after being changed is confirmed, and based on the playing state of the first path of video after being changed, the playing state of a second path of video in the plurality of paths of videos is synchronously adjusted. In the implementation mode, under the condition that the playing state of a first path of video in the multiple paths of videos changes, the playing states of the other paths of videos are changed through control, so that the playing states of the other paths of videos are consistent with the changed playing state of the first path of video, each path of video keeps the same playing progress, and the videos respectively correspond to each other in time, space and content, and therefore synchronous playing is achieved. By applying the embodiment of the application, synchronous playing can be realized without operating the playing progress of each path of video in multiple paths of videos one by one, and the operation is simple and convenient.
Fig. 5 is a schematic flowchart of a multi-channel video synchronization method according to an embodiment of the present disclosure.
As shown in fig. 5, the method of the embodiment of the present application may include the steps of:
s301, sending a video acquisition request to a server, wherein the request carries video information, and the video information comprises at least one of a video name, video generation time and video format information; receiving a plurality of paths of videos issued by the server based on the video information; the multi-channel videos are played on the same screen;
the video data are stored in the server, and the terminal sends a video acquisition request to the server according to the relevant input of the user. The video acquisition request is an instruction for acquiring a video, and the request carries video information, where the video information is used to define the video to be acquired, and may be some information representing video characteristics, such as a video name, a video generation time, a video format, and the like, or may be an identification number composed of numbers and/or letters, such as a video code, and the like, which can distinguish a plurality of videos.
The server selects a plurality of paths of videos according to the video information carried in the video acquisition request, sends the plurality of paths of videos to the terminal, and the terminal plays the plurality of paths of videos on the same screen.
It should be noted that the server may also select a plurality of independent videos according to the video information carried in the video acquisition request, issue the plurality of independent videos to the terminal, and form a plurality of channels of videos and play the videos on the same screen by the terminal side.
S302, monitoring the playing state of each path of video in the multiple paths of videos;
this step can be referred to as S101, and is not described herein.
S303, when the change of the playing state of a first path of video in the multi-path of video is monitored, confirming the changed playing state of the first path of video;
this step can be referred to as S102, and is not described herein.
S304, outputting second prompt information whether to perform directional synchronous playing, wherein the second prompt information also comprises video identifiers of all the videos;
when the playing state of a certain video in the multiple videos changes, it is necessary to determine whether the playing states of the other videos need to be directionally and synchronously adjusted according to the situation, and therefore, after the playing state of the first video after changing is determined, it is also necessary to determine whether the other videos in the multiple videos need to be directionally and synchronously played. And the directional synchronous playing refers to that one or more videos are selected from the other videos and are synchronously played with the first video.
The second prompt information can be output in a text/voice form, the second prompt information is used for confirming whether other paths of videos in the multiple paths of videos need to be directionally and synchronously played, and is used for selecting one/multiple videos directionally and synchronously played with the first path of videos. The video identification can be any combination of letters, numbers, Chinese characters and the like as long as different paths of videos can be distinguished.
When the user inputs negative operation aiming at the second prompt message, the terminal does not display the video identification of each path of video and does not perform directional synchronous adjustment on the playing states of other paths of video in the multi-path of video, and the playing states of other paths of video are maintained as the original state; when the user inputs a determination operation for the second prompt information, step S305 is executed.
It should be noted that, when the user inputs a negation operation for the second prompt information, the terminal may further continue to send third prompt information to the user whether to synchronously play the other videos in the multiple videos, and determine whether to synchronously play the other videos in the multiple videos based on a determination/negation operation of the user for inputting the third prompt information, where the execution process may specifically refer to step S204 and step S205.
S305, acquiring a target video identifier selected aiming at the second prompt message, and determining a second path of video corresponding to the target video identifier;
the video orientation synchronization playing method comprises the steps of mutually related multi-path videos, and the correspondence of two or more than two videos which should be oriented in time, space and content during the oriented synchronization playing. Therefore, under the condition that the playing state of the first path of video changes, the playing state of at least one video which is played synchronously with the first path of video in a directional way should be changed accordingly.
And based on the determination operation of the directional synchronous playing, acquiring a target video identifier selected by the user in each path of video identifier, confirming the video indicated by the target video identifier according to the corresponding relation between the video identifier and each path of video, and defining the video as a second path of video.
The target video identification selected by the user is not limited by the number, and a plurality of videos can be selected to be directionally and synchronously played with the first path of video.
S306, based on the changed playing state of the first path of video, the playing state of a second path of video in the multiple paths of video is synchronously adjusted.
This step can be referred to as S103, and is not described herein.
In the embodiment of the application, a terminal monitors the playing state of each path of video in a plurality of paths of videos, when the playing state of a first path of video in the plurality of paths of videos is monitored to be changed, the playing state of the first path of video after being changed is confirmed, and based on the playing state of the first path of video after being changed, the playing state of a second path of video in the plurality of paths of videos is synchronously adjusted. In the implementation mode, under the condition that the playing state of a first path of video in the multiple paths of videos changes, the playing states of the other paths of videos are changed through control, so that the playing states of the other paths of videos are consistent with the changed playing state of the first path of video, each path of video keeps the same playing progress, and the videos respectively correspond to each other in time, space and content, and therefore synchronous playing is achieved. By applying the embodiment of the application, synchronous playing can be realized without operating the playing progress of each path of video in multiple paths of videos one by one, and the operation is simple and convenient.
