In practical use, for a scene of multiple video streams, the multiple video streams can be combined into one stream by a mixed flow technology, and compared with a scheme of encoding a main picture PPT and audio into one video stream, the scheme can solve the synchronization problem of the multiple video streams of a client to a certain extent. However, for an educational scene, most pictures are mainly PPT with relatively small picture change or low frame rate, a picture-in-picture is a video acquired by a camera with a relatively high frame rate, and if one video stream is synthesized, the capacity of the video stream is increased compared with two video streams, so that more traffic of a user needs to be consumed. The method realizes PPT page turning, animation switching, real-time synchronization of a teacher end painting brush, question insertion and other operations through signaling to realize main picture video playing, can effectively reduce network flow consumption of a user, does not need to consider switching aiming at different network video picture definition, realizes the optimization experience of online and offline main picture quality watching, and is specifically described as follows:
referring to fig. 2, fig. 2 is a schematic flowchart illustrating a method for playing an online video according to an embodiment of the present invention.
The playing method of the online video comprises the following steps:
in step 101, a presentation associated in the online video is obtained, and the presentation is converted into a preset format.
In an embodiment of the application, the online video may be an online education video, where a presentation associated in the online education video is a presentation used in the process of speaking and then performing online education, such as a PPT file, a word file, an excel file, or a pdf file, and the number of the presentations may be one or more. Specifically, when the user clicks and plays the education video, the user terminal automatically generates an acquisition instruction, acquires the presentation associated with the education video from the server, and converts the presentation into a preset format, so that the converted presentation can be displayed and played on the user terminal.
In an embodiment of the application, the initial format of the presentation file may be determined according to a suffix name of the presentation file, where the suffix name of the presentation file includes a file suffix name corresponding to a ppt file, a word file, an excel file, a pdf file, and a file suffix name corresponding to a file in another format supported by the system. When the suffix name of the file belongs to one of the above-mentioned supported document file suffix names, it is judged as a presentation format file. For example, when the file suffix name is. Doc or. Docx, it is judged as a word file, and when the file suffix name is. PPT, it is judged as a PPT file.
For example, a presentation file associated with the acquired online education video may be converted into an SWF format file or an HTML5 format file. The SWF is a Flash animation file based on vectors, is generally created by using FLASH software and generates an SWF file format, and can also convert doc, PPT, PDF and other types of files into the SWF format through corresponding software. SWF format files are widely used to create attractive applications that contain rich video, sound, graphics, and animation. Raw content can be created in Flash or imported from other Adobe applications (such as Photoshop or Illustrator), simple animations can be quickly designed, and advanced interactive projects can be developed using Adobe AcitonScript 3.0. Which designers and developers can use to create presentations, applications, and other content that allows user interaction. Flash may contain simple animations, video content, complex presentations and applications and anything in between. By designing the SWF file format, the addition of user interactive contents can be realized by applications such as online education, video conferences and the like, so that the effects of more intuition, vividness and image are achieved. In the preferred embodiment of the invention, the document file format conversion is carried out by using iSpring software, wherein iSpring is an interactive courseware making tool, so that a presentation document can be easily added into sound, video, test questions, interaction and the like, and simultaneously, the presentation document is converted into a Flash film in an SWF file format by one key, and the original visual and animation effects can be kept while the conversion is carried out.
HTML5, a version of the HTML standard that replaces the HTML4.01 and XHTML1.0 standards made in 1999, is still in the development stage, but most browsers already support some HTML5 technology. HTML5 has two major features: first, the performance of the Web page is enhanced. Next, a function of a Web application such as a local database is added. When referring to HTML5 in a broad sense, we actually refer to a set of combinations of technologies including HTML, CSS, and javascript. It is desirable to reduce browser requirements for rich web application services (RIA) that require plug-ins, such as adobe flash, microsoft silverlight, and oracle java fx, and to provide a more standard set that effectively enhances web applications. Especially, the webpage multimedia characteristic of HTML supports multimedia functions of Audio, video and the like at a webpage end, brings out the best in each other with APPS, camera and Audio-Video functions carried by a website, and has the advantages of supporting multiple devices, crossing platforms and self-adaption. In the preferred embodiment of the present invention, the document file format conversion can also be performed by using the isring software, and the document format file is converted into the HTML5 format for presentation.
In an embodiment of the application, taking the example of converting the PPT file into the HTML5 format file as an example for explanation, the PPT document may be parsed first to obtain the resource file in the PPT file, and converted into the file format supported by the HTML 5. The specific implementation mode can be as follows: and converting various resources (such as pictures, videos, audios, flash animations) and the like used in the whole PPT document into a file format supported by HTML 5. Converting audio and video files used by the document into a standard format of HTML5, for example, all audio is converted into an mp3 format, and all video is converted into an mp4 format of h.264 coding; and converting the shape, rotation and shadow information into a standard format of HTML5 item by item according to the grasped position. And selecting shapes used in the PPT document to be marked by svg vectors according to situations, and generating a corresponding font svg file if external fonts exist. The converted resource file is then loaded to form an HTML page.
In step 102, operation information performed on the presentation in the online video is acquired.
In an embodiment of the application, the operation information performed on the presentation in the online education video may include opening, closing, turning pages, cutting animation, drawing a brush, inserting a white board, and performing exercises, and specifically, the operation information on the presentation may be acquired and stored in the server when the speaker performs online education, and then the user terminal may request the operation information on the presentation in the online education video when requesting the presentation from the server.
In an embodiment of the application, a drawing board may be disposed on an original presentation to record operation information of a speaker on the presentation when performing online education, so that data on the drawing board may be directly extracted after the online education is finished, that is, the operation information of the speaker on the presentation is obtained. Taking an example that a speaker opens a PPT courseware demonstration, the description layer operation data of the PPT courseware is document operation data of the speaker opening or closing the PPT courseware, turning pages and the like, and may also include operation data of text editing (modifying, inserting, thickening or changing fonts and sizes and the like), and the like, and also include description operation data of the speaker drawing, adding labels, drawing lines and the like on the PPT courseware, wherein the description operation data is on a drawing board on the upper layer of the PPT courseware.
In an embodiment of the application, the operation information may further include a time tag, so that an operation corresponding to the speaker may be displayed to the user according to a playing progress of the online education video when the subsequent user terminal plays the presentation, thereby avoiding a time difference.
For example, the following illustrates a process in which a speaker acquires operation information of a PPT file and processes the operation information: when the speaker selects a brush function on the 20 th page of a PPT courseware which is demonstrated in real time at the 20 th minute of a classroom, and presses a mouse at the position of x =10 and y =10 of the selected current page, the initial point position information (10, 10) is recorded in the drawing data; when a speaker moves a held mouse on a page, both the x value and the y value of a moving point are transmitted into the description data to record the position information of each point; when the speaker releases the mouse at the position x =200 and y =200 on the page, the drawing operation is finished, and the drawing data records the end position information (200 ); the speaker generates structured data according to the acquired description operation data, the operation type (painting brush function) and the position information and sends the structured data to the server; and after receiving the structured data sent by the caller, the server analyzes the structured data, adds time information (20 th minute is used as a time tag) to the analyzed data according to the analyzed operation data, and then stores the data in a data storage end, namely a server.
In step 103, signaling is generated according to the operation information, wherein the signaling includes a timestamp corresponding to the operation information.
In an application embodiment, the signaling is generated according to the operation information, and if the online education video includes a plurality of operation information for the presentation, a plurality of corresponding signaling is generated to obtain the signaling data packet. The signaling comprises a timestamp corresponding to the operation information. For example, the time axis for the brush operation in step 102 is 20 minutes.
Specifically, the time axis may be a time schedule corresponding to the operation information in the online education video, for example, when the online education video is played for 20 minutes, the teacher performs a painting operation, and thus the time axis corresponding to the painting operation after being converted into the signaling is 20 minutes. That is, generating a signaling according to the operation information, including:
determining time information of the operation information in the online education video playing process;
and generating the signaling according to the operation information and the time information.
In an application embodiment, a corresponding signaling may also be generated according to an operation type of the operation information, specifically, after the operation information is acquired, the operation type may be determined first, for example, if the operation type is a brush type, the brush operation is generated into the signaling according to a corresponding manner, if the operation type is a page turning type, the page turning operation is generated into the signaling according to a corresponding manner, and the like.
In practical use, the operation information further includes two types of transient operation and continuous operation, for example, a page turning, an opening, a closing and the like for the presentation are transient operations, and for example, a brush operation is a continuous operation, and a certain duration is provided for the continuous operation. Therefore, in one embodiment, if the operation information is an instant operation, the time axis included in the generated signaling is one, that is, the time when the operation occurs. If the operation information is a continuous operation, the number of time axes included in the generated signaling is two, and the two time axes are the start time and the end time of the operation. For example, the time axis of the signaling generated by the operation of turning the PPT from the first page to the second page is 1 minute, and the time axes of the signaling generated by the operation of performing the brush operation on the second page of the PPT may be two, which are 1 minute and 10 seconds, and 1 minute and 15 seconds, respectively.
In step 104, the signaling is loaded during the process of playing the presentation in the preset format according to the timestamp of the signaling.
In one embodiment, if only the main screen including the presentation is included in the online education video, synchronization with the audio or picture-in-picture is not required in this case, and the signaling is displayed according to the playing time of the online education video itself in the case of only one main screen. Because each signaling has a time stamp, the time stamp is displayed according to the playing progress from the beginning of the video.
Compared with the prior art, the embodiment provided by the invention converts the PPT into the HTML5, loads the HTML5 locally, and realizes the operations of PPT page turning, animation switching, real-time synchronization of teacher-side brushes, insertion of exercises and the like through signaling to realize the video playing of the main picture. The scheme can effectively reduce the network flow consumption of the user, does not need to consider the switching of the definition of different network video pictures, and realizes the optimization experience of the definition and stability of the main picture when the main picture is watched on line and off line.
Referring to fig. 3, fig. 3 is a schematic view of a scene for playing a video through a video stream according to an embodiment of the present invention, where the method has a high requirement on the network quality of a user, and needs to provide different image definitions for different network states, and when the network quality of the user is poor, the resolution of the video to be watched is low, and the definition is also poor, which affects the user's watching. With continuing reference to fig. 4, fig. 4 is a scene schematic diagram of a playing method of an online video according to an embodiment of the present invention, which is a method provided by the present application, and since the converted HTML5 page is directly loaded locally without playing through a video stream, and the operation of the speaker is realized through signaling, the image definition is greatly improved.
In addition, the original video streaming scheme is based on H264 video coding, and compression processing is performed after receiving the influence of a network and resolution, and the PPT content in the HTML5 scheme in the application is a vector diagram and is compressed losslessly, so that the definition is obviously improved. Meanwhile, the color of the brush pen is compressed and discolored in the video coding process, and the color and the thickness of the brush pen are reduced by 100% in a signaling scheme, so that the definition is obviously improved.
Furthermore, because the data capacity of the PPT file is much smaller than the capacity of the video itself, the online video playing method provided by the embodiment of the present application can also greatly save the data traffic of the user, and can improve the downloading speed and the playing efficiency. Referring to fig. 5, fig. 5 is a schematic diagram illustrating a comparison of flow consumption according to an embodiment of the present invention. For example, in the period from 16 days at 1 month to 13 days at 2 months, two education video playing methods are respectively used for comparison, and the same online education recorded and broadcast video is played, as can be seen from the figure, in the period when the video stream is used for playing, the flow consumed by the client is 117MB, wherein the flow consumed by the foreground is 115MB, and the flow consumed by the background is 1.76MB. After the playing method provided by the embodiment of the present application is used, the traffic consumed by the client in this period is only 39.59MB, where the traffic consumed by the foreground is 39.36MB, and the traffic consumed by the background is 233KB. Therefore, after the online video playing method provided by the user is used, the definition of the video is improved, and the consumption of data flow is reduced.
In an embodiment, if the online education video further includes audio, the online education video includes audio data. For example, if the speaker outputs an audio signal during the online lecture, the audio data needs to be played during the playing of the converted presentation. In this case, it is necessary to perform sound and picture synchronization first, specifically, an audio time stamp may be used to perform sound and picture synchronization, each signaling has a video time stamp, and all corresponding signaling is displayed according to the current audio time stamp. That is, according to the timestamp of the signaling, the signaling is displayed in the process of playing the presentation in the preset format, including:
synchronizing a timestamp of the signaling with the audio data;
and in the process of playing the presentation in the preset format and the audio data, displaying the signaling according to the playing progress of the audio data.
In another embodiment, if the online education video further includes a picture-in-picture, the online education video includes a picture-in-picture. For example, the speaker captures the picture of the speaker as a picture-in-picture in the education video through the camera in the process of online teaching. The pip is a video content presentation mode, which means that while one video is played in full screen, another video is played on a small area of the screen at the same time. At this time, the pip also needs to be played in the process of playing the converted presentation, wherein in this case, picture synchronization needs to be performed first, and in this case, considering that the main picture is a core part, the important point of attention of the students is the large-picture PPT region, so that the signaling, that is, the large-picture PPT, can be displayed by the video playing time, and the video content of the pip is displayed according to the time of the signaling as a reference. That is, according to the timestamp of the signaling, the signaling is displayed in the process of playing the presentation in the preset format, including:
synchronizing a timestamp of the signaling with the picture-in-picture;
and displaying the signaling in the process of playing the presentation in the preset format according to the timestamp of the signaling, and playing the picture-in-picture according to the timestamp of the signaling.
As can be seen from the above, the method for playing an online video according to the embodiment of the present application can acquire a presentation associated in the online video, convert the presentation into a preset format, detect operation information performed on the presentation in the online video, and generate a signaling according to the operation information, where the signaling includes a timestamp corresponding to the operation information, and load the signaling in a process of playing the presentation in the preset format according to the timestamp of the signaling. The embodiment of the application can convert the presentation into the preset format to be loaded locally at the terminal, and realize the operation in the video process through signaling, so that the scheme can greatly reduce the video capacity, save the user flow, improve the downloading speed and effectively improve the video definition.
The playing method of the online video described in the previous embodiment is described in further detail below by way of example.
In this embodiment, a description will be given by taking an example in which the online video playback device is specifically integrated in a terminal.
Referring to fig. 6, fig. 6 is another schematic flow chart of a playing method of an online video according to an embodiment of the present invention. The method flow can comprise the following steps:
In an embodiment of the application, the online video may be an online education video, and a presentation associated in the online education video is a presentation used in the process of performing online education again by using a lecture, such as a PPT file. The number of the presentations can be one or more. Specifically, when the user clicks and plays the education video, the user terminal automatically generates an acquisition instruction, and acquires the presentation associated with the education video from the server.
Further, in an embodiment of the application, composition information of the presentation and elements included in the presentation may be further extracted, where the composition information of the presentation may include global information of the presentation, such as length and width, powerPoint version used, default style included, font size, and the like. The elements included in the presentation may be various resources used throughout the presentation, such as pictures, video, audio, flash animation, etc.,
