Detailed Description
Embodiments of the present invention will be described in detail below, the embodiments described with reference to the drawings being illustrative, and the embodiments of the present invention will be described in detail below.
In order to optimize the problem of long delivery waiting time in the process of delivering all data frames to a display end at the same time by a decoding end, the embodiment of the invention provides a method for controlling terminal display, which can reduce the time consumed in the process of waiting delivery of the data frames.
A method of controlling a terminal display according to an embodiment of the present invention is described below with reference to fig. 1 to 4.
Fig. 1 is a flowchart of a method of controlling a terminal display according to an embodiment of the present invention. As shown in FIG. 1, the method of the embodiment of the present invention at least includes steps S1-S3, which are described in detail below.
And S1, acquiring the video compressed data.
In the embodiment of the invention, when a user watches live online video, experiences a cloud game or applies real-time media such as cloud office and the like, the terminal firstly needs to acquire corresponding video compressed data, the decoding end decodes and processes the video compressed data to generate a video image, and the video image is displayed to the user by the display end.
S2, the video compressed data is decoded in units of data frames.
In the embodiment of the invention, after the decoding end decodes the video compressed data, the display end can display the decoded video data. In the process of video playing, the played video image is composed of decoded data frames arranged according to time, so that the decoding end decodes the video compressed data into a certain number of data frames.
And S3, obtaining the decoded data frame, and delivering the decoded data frame to the display end until the decoding of the video compression data is completed.
In the embodiment of the invention, the decoding end can directly deliver the decoded data frame to the display end, and the decoding end does not need to wait for all the video compressed data to be completely decoded and then completely deliver the decoded data frame to the display end. Namely, the decoding end decodes the video compressed data, delivers the decoded data frame, and the display end receives the decoded data frame, and after all the video compressed data are decoded, the delivery process of the decoded data frame can be almost completed at the same time, so that the time of playing a link due to time consumption of the decoded data frame in waiting delivery can be reduced, and low delay is realized.
According to the method for controlling the terminal display, the decoding end decodes the video compressed data by taking the data frame as the unit, the obtained decoded data frame is directly delivered to the display end, the decoding end and the display end are in asynchronous working modes, the two parts are independent, and compared with the process that all the data frames are delivered to the display end at the same time after the video compressed data is completely decoded, the time consumed in the process that the data frames wait to be delivered is reduced, the purposes of instantaneity, high efficiency and low time delay are achieved, and the watching experience feeling of a user is guaranteed.
In the embodiment of the present invention, when delivering the decoded data frames to the display end, delivering a preset number of decoded data frames to the display end may be included. The preset number of decoded data frames may be partial data frames obtained by decoding the video compressed data, or may be total data frames obtained by decoding the video compressed data.
In the embodiment of the present invention, the preset number of decoded data frames is N, where N is greater than or equal to 1 and less than or equal to N and is a total data frame of decoded video compressed data.
It can be understood that the terminal obtains the video compression data, and decodes the video compression data to obtain a data frame containing all the video compression data. For example, the data frames containing all the video compressed data are the total data frames of the decoded video compressed data, and the display end acquires and plays the total data frames of the decoded video compressed data, so that a complete video image can be obtained.
According to the method for controlling the display of the terminal, provided by the embodiment of the invention, the decoding end continuously decodes the video compressed data, the decoded data frames can be continuously acquired, and the decoded data frames with the preset number of N can be delivered to the display end. And N is more than or equal to 1 and less than or equal to N, so that the process of decoding the video compressed data by the decoding end and the process of delivering the decoded data frames to the display end can be carried out simultaneously. The problem that the delivery waiting time occupies the playing link time due to excessive total data frames after the video compressed data is decoded when all the data frames after the video compressed data is completely decoded are delivered to the display end at the same time is solved. In the whole decoding process of the decoding end, for example, the configuration may be that after the decoding end acquires a frame of data, the frame of data is delivered to the display end. Or, the delivery can be performed every time the decoding end acquires a corresponding number of data frames, so as to save the time when the data frames wait for delivery.
Fig. 2 is a flowchart of a method for controlling a terminal display according to another embodiment of the present invention, and as shown in fig. 2, the method according to the embodiment of the present invention further includes step S4, which is specifically described below.
And S4, after the video compressed data is decoded, sending a decoding completion notification message to the display terminal.
In the embodiment of the invention, after the decoding end finishes delivering all the decoded data frames to the display end, the display end is still in the state of receiving the data frames, so the display end can send the decoding completion notification information to the frame queue to remind the display end of finishing decoding the video compressed data and delivering the data frames.
In the embodiment of the invention, the decoding end decodes the data frame as a unit to obtain the decoded data frame and directly delivers the decoded data frame to the display end, and the display end needs to process the received decoded data frame so as to realize the function of efficiently and immediately playing the video. Fig. 3 is a flowchart of a method for controlling terminal display according to another embodiment of the present invention, where a process of a display end processing a decoded data frame at least includes steps S301 to S303, which are specifically described as follows.
S301, receiving the decoded data frame.
It can be understood that the decoding end can decode the video compressed data into data frames and deliver the decoded data frames to the display end in advance, and the display end can also receive the decoded data frames.
S302, the time stamp of the data frame is obtained.
It can be understood that, after receiving the decoded data frames, the display end will simultaneously obtain the time stamps of the data frames, so that a certain number of data frames can be displayed according to a predetermined time sequence during video playing. For example, in the process from decoding video images to delivering data frames, the data frames may be out of order or arranged in a wrong order. The display end can arrange the received data frames according to the time sequence according to the acquired time stamp information of the data frames, so that errors are prevented from occurring in the subsequent video display process, and the experience of a user is prevented from being influenced.
And S303, forming a frame queue according to the time stamp of the data frame.
In the embodiment of the invention, the display end firstly arranges the received data frames according to the time sequence, temporarily stores the arranged data frames into the display end and waits for display. The frame queue is used for temporarily storing the arranged data frames.
Compared with the method that the decoded data frames are stored in the decoding end in advance, and the decoded data frames are delivered to the display end for display after the video compression data are completely decoded, the method for controlling the display of the terminal stores the decoded data frames in the frame queue of the display end temporarily, and the decoded data frames are arranged in the frame queue according to the time sequence. When the display end needs to display, the arranged data frames can be directly taken away from the frame queue for display, so that the time for simultaneously delivering all the data frames to the link is saved, the purposes of instantaneity, high efficiency and low time delay are achieved, and the watching experience of a user is ensured.
In an embodiment of the present invention, the method of controlling a terminal display further includes acquiring a data frame from the frame queue for display in response to the decoding completion notification information.
In the embodiment of the invention, as the decoding end can decode the video compressed data and deliver the data frames at the same time, the display end can continuously receive the decoded data frames and form the frame queue according to the time stamps of the data frames. Therefore, when the decoding end completes decoding all the video compression data, the process of delivering the decoded data frames to the display end can be completed almost at the same time. However, the display end is still in a state of receiving the data frame after receiving all the decoded data frames, so the display end can send decoding completion notification information to the frame queue, the display end can identify the decoding completion notification information, determine to receive all the decoded data frames according to the completion notification information, and then execute to acquire all the data frames from the frame queue and display the data frames to a user.
In an embodiment of the present invention, as shown in fig. 4, a schematic diagram of a method for controlling a terminal display according to an embodiment of the present invention is shown. And after the decoding end acquires the video compression data, decoding the video compression data to acquire a decoded data frame, and meanwhile delivering the acquired decoded data frame to the display end to realize the function of delivering the data frame while decoding the video compression data. The display end forms a frame queue with the received data frames according to the time sequence, the decoding end completes the process of delivering all decoded data frames to the display end almost simultaneously after the decoding end completes the decoding of all video compressed data, at the moment, the decoding end sends decoding completion notification information to the frame queue, the display end can identify the decoding completion notification information and determine that all decoded data frames are received, and then all data frames are acquired from the frame queue to be displayed to a user.
According to the method for controlling the terminal display, the decoding end and the display end are in asynchronous working modes by controlling the decoding end to simultaneously realize the functions of decoding the video compressed data and delivering the data frames, so that the link time waiting in the process of simultaneously delivering all the data frames is saved, the video stream can be quickly decoded and immediately displayed to a user, and the method meets the requirement of high-instantaneity application.
