Example two
The present embodiment provides a video playing method under an ios system, as shown in fig. 2 to fig. 6. The pushing method depends on a first application program, wherein the first application program comprises a first window 1 which is positioned in a desktop area and used for displaying pictures or videos, and a first operation interface 3 which responds to clicking on an icon 2 which is not covered by the first window in the desktop area; and the first operation interface 3 which responds covers the first window 1.
The overall flow is shown in fig. 2, and specifically as follows:
and pulling the latest dynamic state, if the latest dynamic state is a picture, stopping the current playing task of the first window 1 on the screen, and updating the display content of the first window 1 into the latest dynamic picture. And if the latest dynamic state is the video, updating the display content of the first window 1 to be a cover page image of the video, and performing video downloading judgment. If the video is not completely downloaded, the first window is always kept to display the cover page of the video, the downloading judgment process is stopped from the polling judgment to the completion of the downloading, and the video is subjected to the photo processing judgment. The process of the picture processing is to extract the video into a form of a picture set according to a specified time interval, and the picture processing mode is further explained in the subsequent paragraphs of the description. The time interval is determined according to the total length of the video and the number of pictures to be obtained after the picture processing. The number of the pictures is determined according to the available internal memory of the mobile terminal before the video is subjected to the picture processing each time. If the picturizing processing is judged to be negative, polling is carried out until the picturizing processing is finished, and a playing task is started.
The mode of determining the number of the pictures obtained after the picture formation according to the memory can be a stage type, and also can be a functional relation of mapping between the memory and the number of the pictures. The correspondence relationship of the specific time period is as follows: under the condition that the video length is 5 seconds, the number of corresponding pictures after being pictured below 2G in the memory is 10, the number of corresponding pictures after being pictured between 2G and 4G in the memory is 20, and the number of corresponding pictures after being pictured above 4G in the memory is 30. Besides the stage-type corresponding relation, the continuous function corresponding relation of the number of the pictures relative to the memory and the video length dual independent variables can also be established. The single variable is preferably that the more the remaining memory is, the larger the number of pictures is, and the larger the number of pictures increases faster as the remaining memory is larger; the longer the video length, the larger the number of pictures, and the slower the number of pictures grows with more memory remaining. More preferably, the method for determining the number of the pictures based on the memory and video length bivariates is that a cross influence between the memory and the video length can be established, and further, the memory loss possibly related to the length in the playing process is taken into account, so that the use condition of the memory and the playing effect of the simulated video after the pictures are made are effectively balanced.
The application program provided by the embodiment can directly display the video dynamically without any trigger in the unlocked screen, and the user can directly see the dynamically updated video dynamic after unlocking. Besides the window directly showing the dynamically updated video in the screen, the application program of the embodiment may also trigger other processes of the application program by clicking an icon of the application program in the screen. Other processes include taking pictures, videos and pushing to buddies, adding buddies, deleting buddies, viewing historical messages, and commenting and agreeing functions on historical messages. The video presented in the first window 1 will also appear in the history message of the application and will be presented in video format rather than as a collection of pictures.
A first operation interface for viewing history messages in the application program entering in response to clicking the icon is shown in fig. 6, in which the application program video playing window 3 plays the history video in the format of video rather than in the form of a picture set, and other videos which are being shown in the first window 1, or have been shown, or are not shown in the first window 1 due to the close entering time of multiple videos all appear in the history messages.
The process flow of the imaging process is shown in fig. 3, and specifically includes the following steps:
and after the imaging processing is started, adding the video into a video queue to be imaged by taking the feed ID as an identifier, and synchronously extracting the images by the thread. And specifically judging whether the video can be added into the queue, if not, stopping the video imaging process, if so, stopping the current video imaging task, and listing the video into the latest imaging task. The judgment method is as follows: if the time node of the video is updated compared with the time nodes of the videos in all the queues, stopping the process of the current video picture and carrying out picture processing on the video; and if the time node of the video is later than that of any video in the queue, the video is not subjected to the picture processing, and only the video queue is added for displaying in the historical message after responding to the application program started after the icon. And (4) finishing the imaging task, if not, judging whether the retry upper limit is reached, if not, trying to add the imaging task into the imaging task queue by taking the feed ID as the identifier again to perform an image extraction process, and meanwhile, adding 1 to the retry number. Because there may be a plurality of videos entering the queue at the same time, if the video is not the latest video, the displayed scene is only the historical message query in the application program, and then the imaging processing is not needed. The scheme design for performing the picture processing only on the video which needs to be displayed in the first window improves the processing efficiency and reduces unnecessary memory consumption. Because the first window can only display one video at the same time, namely, only the latest video in the video queue is subjected to the picture processing. If the video is updated in the processing process, the time of the video is updated, the currently processed video is considered to be no more the latest video, and the video is no longer possible to be displayed in the first window, so that the power consumption and the memory consumption of the application program are stabilized at the same level, excessive resource consumption is avoided, the current video picture processing is stopped, and the newly entered video is subjected to picture processing. If the termination caused by introducing a new video is caused by non-queue updating dynamic in the process of processing the latest video by the pictures, the current video in the queue is continuously processed by the pictures after the termination. For example, although the number of the picture sets subjected to the picture-in-picture processing based on the current memory condition before each video picture-in-picture processing is avoided due to insufficient memory, the memory is still insufficient due to the application programs of other threads, and thus the running of the application program is wrong. And after the error or the abnormality is eliminated, if no updated video enters the queue, increasing a retry chance for the current video, and continuing to perform the picture processing on the current video until the number of the pictures obtained after the picture processing is the number of the picture sets subjected to the picture processing based on the current memory condition before the picture processing, and then stopping. In the embodiment, the video management is performed by adding the queue, and the field recovery measures of unnecessary memory consumption and accidental abnormal conditions brought by the updated video are compatible, so that each video in the queue has the optimal picture processing quantity optimization, the picture extraction task has the retry chance before the specified quantity is reached, and the efficient and accurate completion of the picture extraction task is ensured.
The single picture extraction task adopts a producer-consumer design mode, the production end mainly has the function of extracting pictures in a certain range from the video every time, and every batch of pictures is sent to a channel batch until the extraction of the number of the pictures in the picture set determined according to the memory is finished. And meanwhile, the consumption end task is to store the extracted video pictures on a disk, name the file names in a time sequence or add time sequence labels to the pictures to ensure the subsequent playing sequence.
The video playing process is shown in fig. 4, and specifically as follows:
and the frame folder accesses the extracted pictures, continuously reads the pictures of the plurality of frame folders in an unlimited sequence in parallel, converts the pictures into the round-corner pictures, and transmits the processed round-corner pictures to an input/output channel in an unlimited sequence in parallel. And adding one to the index value corresponding to the file name each time during parallel processing, and ending the task of the current round when the end is reached.
The input and output channel inputs the picture into the screening module, and the screening module maintains an index value corresponding to the file name, and the index value can be used for determining and searching the picture of the next frame to be played. The screening module also maintains a gallery that stores pictures that have arrived unsent. And continuously trying to send the picture corresponding to the current index value, if the picture exists in the gallery, directly removing the picture from the gallery and sending the picture to the updating channel, and if the picture does not exist in the gallery, trying to acquire the index value of the latest arrived picture from the input and output channel until the index value is matched with the current index value to be sent, and sending the picture corresponding to the index value. And sequentially screening and searching the pictures corresponding to the index values until all the pictures with the index values of the video are sent. In the process of picture processing and transmission, due to the problems of networks, pictures or processing programs, delay or time requirements of different degrees exist, in the embodiment, the problem of delay or time requirements is not considered in each previous stage, multiple threads are processed on any picture with the minimum delay in parallel until the picture is input into the screening module and then sequenced, the reliable caching strategy realizes the minimum time occupation of the picture processing and transmission, and the video can be supported to be smoothly played in the subsequent playing process based on the reliable caching strategy.
The playing process after video imaging is as follows:
the first window only plays a latest dynamic video each time, the dynamic ID marks the video dynamic state, and the current playing task is stopped each time a new video triggers updating.
And the updating thread receives the picture from the updating channel, updates the received picture to the first window and withdraws the picture displayed in the first window. And updating the ready-to-control updating speed, if the interval time is less than 40ms, postponing the updating speed of the pictures to 40ms, and if the time interval for receiving the pictures sent by the screening module is greater than 40ms, taking the time interval for receiving the pictures sent by the screening module as the time interval. The setting of the interval time is determined according to the processing time evaluated in advance, so that the fluency of the video is improved, the pause caused by unnecessary delay of a single picture is avoided, and the fluency of video updating is kept. The time interval is not fixed to be 40ms, and optimization determination can be carried out according to the current video length, the number of extracted pictures and the use condition of the memory. Under the application of the video imaging and updating thread, the first window on the screen of the mobile terminal simulates the video playing effect through the playing image set, and the user observation and the video playing have no obvious difference.
In the embodiment, the video dynamics are respectively set in the window directly positioned on the screen, and the history dynamics of the application program popped up corresponding to the clicked icon. The dynamic update provided by the embodiment combines the picture set simulation video with the playing video, overcomes the technical defect that the window for displaying the icon conventionally cannot display the video, improves the user experience, enhances the intimacy and intuition of information transmission among friends capable of sending information mutually related to the application program compared with the technical scheme that the application program can be accessed by clicking and then the dynamic video is seen, and enhances the playability of the application program better by the effect of screen overlocking. The combination of independent and separately arranged dynamic display of an independent window or independent video display of an application program cannot achieve the technical effect of more intuitive user experience obtained by the combination of the above. In the combining process of the two, the two technical schemes are not overlapped, but integrated allocation is performed based on a video queue mode, so that the balance between memory consumption and user experience is realized. Further, compared with other application programs, because the dynamic display of the application program is fixed on the screen desktop, the dynamic display does not act by clicking an icon or other triggering modes, and the technical problem of high power consumption is easily caused by long-term background execution.
EXAMPLE III
