Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Fig. 1 is a schematic flow chart illustrating a video display method according to an embodiment of the present invention; as shown in fig. 1, when applied to a terminal, the video display method specifically includes the following steps:
step S101, acquiring the current tributary video and the previous tributary accumulated time length of the playing video.
It should be noted that, when the server performs long-time network recording on a program at a time T0, as shown in fig. 2, the code stream recorded by the network records a video segment with a time length of P0 for a long time, the time length of the recorded code stream is N × P0+ M, the recording time is greater than T0, that is, N T0+ M (M >0, N >0), and the total recording time is recorded as the total time length of the recorded program. When the terminal plays back the program recorded by the network, the program playing address and the total time length can be obtained. The playing progress of the terminal display is converted into the display time in seconds according to the time unit of a specific system by analyzing the PTS (presentation time) in the network downloading video frames. The playback related operation is normal in the time of T0, but the playing progress always stays in the time period of T0, and the discontinuous time of the video frames needs to be processed continuously in order to make the whole video segment played back normally. The method is that the player determines the playing position of the current media through Vpts (video display time stamp) in the TS packet, and feeds back the current playing time according to the Vpts. The player plays the on-demand program, the network time-shifting program and the Catch-up TV program, and the total time Td of playing the program is obtained from the server; the player analyzes the Vpts from the network packet to calculate the playing time, and feeds back the current playing time according to the requirement of the server, the playing time can display the playing progress in a progress bar mode, and the normal playing can be realized only when the picture performance and the progress bar display are synchronous. The method can well solve the problem that the Vpts is discontinuous in the total time Td of playing the program. The case where Vpts is continuous means that Vpts is continuously increased for the total period Td. The case where Vpts is discontinuous refers to a case where Vpts increases from 0 to the maximum value PO and returns to 0 a plurality of times within the total period Td, and is not continuously incremented. Similarly, the tributaries with the total duration Tx form a stream with the total duration Td after being subjected to head-to-tail compounding for a plurality of times, and Vpts of TS packets is not subjected to continuous compounding processing in the compounding process.
In this embodiment, the currently played video played at the terminal includes a plurality of tributary videos, where timestamps of each frame of video image in the tributary videos are continuously increased, a breakpoint occurs between each tributary video, video frame images before and after the breakpoint are discontinuous, and an image timestamp of a start frame image of the current tributary video is smaller than an image timestamp of a last frame image of a previous tributary video; the terminal analyzes the network packet, the TS packet and the local decoding of the video stream embryo sent by the server to obtain the current tributary video, and the terminal can also calculate the accumulated duration of all the current tributary videos.
Step S102, obtaining an image time stamp of a start frame video image in the current tributary video.
In this embodiment, the image timestamp of the start frame video image is an image timestamp on the first frame video image in the current tributary video.
And step S103, acquiring the current frame video display time of the current frame video image according to the image time stamp.
In this embodiment, the current frame video display time of the current frame video image is equal to the difference between the image time stamp of the current frame video image and the image time stamp of the start frame video image divided by 90000 and in milliseconds; the image timestamp of the current frame video image is a timestamp set when the server transmits the current frame video image to the terminal, the current frame video display time of the current frame video image is the time when the current frame video image appears in the current tributary video, and the video display time of the initial frame video image in the current tributary video is set to be 0.
And step S104, if the current frame video display time is longer than the previous frame video display time, obtaining the progress display time of the current frame video image according to the previous tributary accumulated duration and the current frame video display time.
It should be noted that, when the current frame video display time of the current frame video image is calculated to be greater than the display time of the previous frame video image, it indicates that the currently played video frame is continuous, so the progress display time of the current frame video image is the sum of the previous tributary accumulated duration and the current frame video display time.
Fig. 3 is a schematic flow chart illustrating another video display method according to an embodiment of the present invention; as shown in fig. 3, the video display method further includes the steps of:
step S201, if the display time of the current frame video is less than the display time of the previous frame video, taking the previous frame video image as a current tributary video breakpoint, and taking the current frame video image as a start frame video image of the next tributary video;
step S202, acquiring the current tributary duration of the current tributary video according to the current tributary video breakpoint;
step S203, updating the previous tributary accumulated time length according to the current tributary time length to obtain an updated value of the tributary accumulated time length;
and step S204, taking the updated value of the tributary accumulated time length as the progress display time of the current frame video image and the previous tributary accumulated time length of the next tributary video.
In this embodiment, if the current frame video display time is less than the previous frame video display time, it indicates that a video breakpoint occurs, and the video breakpoint causes discontinuity between the current tributary video and the next tributary video, so that the previous frame video image is used as the current tributary video breakpoint, the current frame video image is used as the start frame video image of the next tributary video, the video display time of the previous frame video image is used as the current tributary duration of the current tributary video, and the sum of the current tributary duration and the previous tributary accumulated duration is used as the progress display time of the current frame video image and the previous tributary accumulated duration of the next tributary video.
Compared with the prior art, the invention has the beneficial effects that:
the video display method calculates the display time of each frame of video image by the image time stamp of each frame of video image in the playing video, obtains whether the current playing is at the breakpoint according to the display time of two adjacent frames of video images, and carries out the calculation method of different progress display times according to the judgment condition of whether the current playing is at the breakpoint, so that the display time of the playing video frame is consistent with the display time of the progress bar, the problem that the display time of the playing progress is not synchronous with the actually played image due to the discontinuous video frame time in the prior art is solved, and smooth video playing experience is provided for users.
In another embodiment of the present invention, obtaining the current tributary duration of the current tributary video according to the current tributary video breakpoint includes: acquiring a current playing multiple; acquiring the time span under the current playing multiple according to the current playing multiple and the current video frame rate; and acquiring the current tributary duration according to the time span and the current tributary video breakpoint.
In this embodiment, obtaining the current tributary duration according to the time span and the current tributary video breakpoint includes: when the time span is larger than the current frame video display time, acquiring a difference value between the time span and the current frame video display time; and acquiring the sum of the difference value and the display time of the previous frame of video to obtain the current tributary duration.
In this embodiment, obtaining the current tributary duration according to the time span and the current tributary video breakpoint, further includes: and when the time span is less than the display time of the current frame video, the current tributary duration is equal to the display time of the last frame video.
It should be noted that the current play multiple includes normal play, fast forward play, and fast reverse play; the terminal can realize fast forward and fast backward according to the practical scheme, the fast forward unit defines the time span as Istep, namely spanning 1 video I frame, then Prate speed multiplying speed spans Prate I frames. If the video frame rate is Y, the time span across the Prate frame is Prate/Y seconds. The relation between the fast-forward speed and the actual time span is Tstep ═ Prate × 1000/Y milliseconds, namely the quotient unit of the fast-forward speed multiplied by 1000 and divided by the frame rate is milliseconds; if the time span corresponding to the current playing multiple is larger than the current obtaining display time, the tributary time length is equal to the sum of the difference value obtained by subtracting the current frame video display time from the time span and adding one frame video display time, and if the time span corresponding to the current playing multiple is smaller than the current obtaining display time, the tributary time length is equal to the previous frame video display time.
In another embodiment of the present invention, when the time length of each tributary is equal, acquiring the accumulated time length of the previous tributaries includes: acquiring the accumulated number of current breakpoints according to the current playing multiple; and the previous tributary accumulated time length is equal to the accumulated quantity of the current break points multiplied by the time length of each tributary.
Further, obtaining the cumulative number of current breakpoints according to the current playing multiple includes: if the current playing multiple is normal playing or fast forward playing and the current frame video display time is less than the previous frame video display time, the current breakpoint cumulative number is the previous breakpoint cumulative number by 1; and if the current playing multiple is fast-backward playing and the current frame video display time is greater than the previous frame video display time, the current breakpoint cumulative number is the cumulative number of the previous breakpoint decreased by 1.
It should be noted that, under the normal play and fast forward conditions, if the display time of the video acquired this time is less than the last display time, it is detected that a discontinuity point occurs under the normal play and fast forward conditions. Recording the number of discontinuous points and accumulating 1; adding the product of the number of discontinuous points such as the display time of the progress bar and the tributary duration to the video display time obtained at this time; under the condition of fast backward, if the display time of the video acquired this time is longer than the last display time, detecting a discontinuous point under the condition of fast backward, and decreasing the number of discontinuous points by 1; the display time of the progress bar is equal to the difference value obtained by subtracting 1 from the number of discontinuous points, multiplied by the tributary duration and added with the video display time acquired this time.
Fig. 4 is a schematic flowchart illustrating a video display method according to another embodiment of the present invention; as shown in fig. 4, the video display method further includes the steps of:
step S301, acquiring the total duration from a server, acquiring a first video timestamp, and acquiring a current playing multiple;
step S302, detecting a first discontinuous point, and if the discontinuous point is not detected, calculating display time according to the information of the video;
step S303, if a first discontinuous point is detected and the current position does not reach the end of the file, calculating the total display duration of the first section of video according to the current playing multiple information;
step S304, detecting the ith discontinuous point, calculating the total display time length of the ith segment, and calculating the total display time length according to the information such as the current playing multiple and the like.
It should be noted that, the terminal plays the code stream after acquiring the playing address, and analyzes and acquires a first time stamp Vpts0 of the video frame of the code stream; and processing and searching the discontinuous point of the first video frame according to the situation of the current playing mode in modes of fast forward, fast backward or normal speed multiplication and the like. And displaying synchronous playing at a time point within the SEEK time-up period (T0, N P0+ M) before the first discontinuous point is not found. According to the requirement of playing time continuity, a first discontinuous point firstly appears in the event of fast forward or normal double speed playing; the two events are classified into a time increment playing mode, and only the playing times are different.
The display time is the time stamp difference multiplied by the unit time and then converted to seconds for display. The unit time of the system refers to the corresponding conversion relation between the clock period of the crystal oscillator of the system and the milliseconds, namely how many milliseconds one clock period corresponds to. Let the current playback speed be Prate, the timestamp of the first played video frame be Vstc0, the timestamp of the current played video frame be Vstcj, and the timestamp of the previous video frame be Vstci. If Vstcj is greater than Vstci, no discontinuity is found, and the display time is Vstcj minus Vstc0 multiplied by the system unit time and converted to a second display.
If Vstcj is less than Vstci, it means that the first video frame timestamp discontinuity is found in this operation. In this case, the video continuous-time period P0 is estimated in cooperation with the Prate value. Vstcj minus Vstc0 to obtain a difference Vtdif, P0 equals Tstep plus Vstci minus Vstcj if time span Tstep corresponding to Prate is greater than Vtdif; otherwise P0 is equal to the difference of Vstci minus Vstc 0. And after the video continuous time duration P0 is obtained, calculating the actual display time according to the fast forward and fast backward conditions.
Under the conditions of normal playing and fast forward, recording as a discontinuous point occurrence when Vstci is smaller than Vstcj, namely the number L of occurrences of the discontinuous point is accumulated to 1, and displaying the difference value of the sum of the product of L × P0 and the sum of Vstcj minus Vstc0 by the progress bar; in the fast backward case, when Vstci is greater than Vstcj, it is recorded as a discontinuity occurrence, i.e., the number of occurrences L minus 1, and the time displayed by the bar is the product of L × P0 plus the difference between Vstcj minus Vstc 0.
In this embodiment, the set-top box in the IPTV system can provide good playing experience by being used as a playing terminal device to normally decode audio and video frames downloaded by a network, and simultaneously cooperating with an interface to control and display a playing progress. The set-top box can normally play the recorded and played code stream with discontinuous video frame time stamps by using the method. The method comprises the steps of detecting the occurrence point of a discontinuous time stamp of a first video frame, estimating the continuous duration of the time stamp of the video frame, and calculating the continuous display time value of fast forward and fast backward by recording the discontinuous point and the continuous duration.
Further, recording a first video frame timestamp, detecting a first video frame discontinuous timestamp occurrence point by calculating a difference value of the previous and next video frame timestamps in a time-increment playing mode, wherein the occurrence of the discontinuous timestamp shows that the next timestamp is smaller than the previous timestamp. And calculating the continuous time length according to the current playing multiple in the time increment playing mode. The difference value of each time stamp minus the first time stamp of the video starting playing is multiplied by the unit time of the system to obtain the corresponding playing relative time of the current video frame.
Further, when the detection of the first video frame discontinuous time stamp occurrence point is that the first discontinuous point is detected, the relationship between the current playing relative time and the playing multiple is compared, and if the current playing multiple is greater than the current playing relative time, the continuous time duration Tx is the difference between the previous playing relative time and the current playing relative time plus the playing multiple speed. Otherwise, the continuous duration Tx is the previous playing relative time.
And the continuous display time during the estimation of fast forward is L of the number of the discontinuous points of synchronous recording. When a discontinuity L plus 1 is encountered, the display time is the relative playing time converted by the product of L multiplied by Tx plus the current time stamp.
Further, the estimated continuous display time during fast backward is the number of the discontinuous points of the synchronous record. A fast-back discontinuity is manifested by a current timestamp that is greater than a previous timestamp. When a discontinuous point is encountered, the discontinuous point count L is reduced by 1; the display time is the relative time of playing converted from the product of L multiplied by Tx and the current time stamp.
