Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. 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 invention.
Fig. 1 is an exemplary division of modules for performing video processing in a terminal, and as shown in fig. 1, the terminal includes a data downloading and caching module, an audio/video separation module, a decoding module, an audio/video synchronization module, and an output module. The data downloading and caching module is used for downloading and caching video data to be played from a network and sending the data to the audio and video separation module, the audio and video separation module is used for carrying out audio and video separation and sending the separated audio data and video data to the decoding module, the decoding module is used for decoding the audio data and the video data respectively and then sending the decoded data to the audio and video synchronization module, and the audio and video synchronization module is used for sending the audio data and the video data to the output module after synchronizing the playing time of the audio data and the video data and outputting the audio data and the video data to the output module and playing the data. In the above video processing process, there may be buffer data amount in a plurality of modules, but the buffer data amount in all the modules may not be directly detected. For example, the data downloading and caching module, the audio/video separation module, and the decoding module may have cached data amounts, where the cached data amounts of the data downloading and caching module and the audio/video separation module may be accurately calculated by determining the playing time, but the cached data amount in the decoding module cannot be calculated, and the cached data amount is not considered in the prior art.
In the prior art, the obtained cache data amount which can be calculated is directly used as the total cache data amount in the terminal, and in this processing mode, the cache data amount used as a basis for judging whether to buffer is smaller than the actual cache data amount in the terminal, so that the situation that buffering is performed when buffering is not needed may occur, the buffering frequency is too much, and the user experience is influenced.
Based on the above problems, the present invention provides a method for determining a video playing state based on a buffering time, which makes the determined total terminal buffering time closer to the actual total terminal buffering time by estimating the decoding module and the buffering time of the subsequent module, thereby reducing the buffering times and improving the user experience.
The invention uses the buffer time to express the buffer data quantity.
Fig. 2 is a schematic flowchart of a first embodiment of a method for determining a video playing status based on a buffering time according to the present invention, as shown in fig. 2, the method includes:
s201, the terminal determines the timestamp information in the plurality of data frames received by the decoding module.
Specifically, the timestamp information includes a Presentation Time Stamp (PTS) and a maximum video PTS.
When the audio and video separation module transmits data to the decoding module, that is, when data frames are transmitted, the terminal can record the PTS of each frame. The PTS of a frame refers to the playing time of the video corresponding to the frame, and the terminal acquires the maximum time among the playing times. This maximum time represents the latest playing time in the video delivered by the audio-video separation module to the decoding module.
Taking the audio PTS as an example, it is assumed that the audio and video separation module transfers 3 data frames to the decoding module, the audio PTS of the first data frame is 1 second, the audio PTS of the second data frame is 5 seconds, and the audio PTS of the third data frame is 10 seconds. The latest playing time corresponding to the video data transmitted from the audio/video separation module to the decoding module is 10 seconds.
S202, the terminal acquires the current video playing time.
The current video playing time refers to the time when the video is currently played, for example, when a video is currently played for 10 seconds, the current video playing time of the video is 10 seconds.
S203, the terminal determines a decoding module and second cache time of the decoding module in a rear module according to the timestamp information and the current video playing time.
The video playing processing of the post module of the decoding module is carried out after the decoding module.
For example, in the module division shown in fig. 1, the following modules of the decoding module refer to an audio and video synchronization module and an output module.
In this step, the terminal may determine the decoding module and its subsequent module, that is, the second buffer time in the module that cannot calculate the buffer time, based on the maximum audio PTS and the maximum video PTS transmitted by the audio/video separation module to the decoding module and the current playing time of the video.
And S204, the terminal judges whether to continue playing the video according to the second cache time and the sum of the first cache time in the previous module of the decoding module.
For example, in the module division shown in fig. 1, the previous modules of the decoding module are an audio/video separation module and a previous module of the audio/video separation module, and the previous module of the audio/video separation module includes a data downloading and buffering module.
Since the buffering time of the audio/video separation module and the previous module thereof can be directly obtained by calculation, the terminal can calculate the buffering time of the audio/video separation module and the previous module thereof in advance before the step. For example, the terminal may determine the buffering time of the data downloading and buffering module by the amount of data stored in the data downloading and buffering module.
In the prior art, the buffering time of the previous module of the decoding module, i.e., the audio/video separation module and the previous module thereof, can be directly read, and the buffering time of the decoding module and the subsequent module thereof cannot be directly read, so that the buffering time is not considered in the prior art, which results in inaccurate total buffering time determined by the terminal. In this embodiment, the terminal may estimate the decoding module and the buffering time of the subsequent module according to the timestamp information and the current video playing time in the plurality of data frames received by the decoding module, that is, based on the timestamp information and the current video playing time of the plurality of data frames received by the decoding module, the buffering time that is not considered in the prior art may be estimated, and further, the buffering time is added to the total buffering time, so that the determined total buffering time of the terminal is closer to the actual total buffering time, thereby reducing the buffering times and improving the user experience.
On the basis of the foregoing embodiment, this embodiment relates to a specific method for determining, by a terminal, a second buffering time in a decoding module and a subsequent module of the decoding module according to timestamp information and a current video playing time, that is, fig. 3 is a schematic flow diagram of a second embodiment of a method for determining a video playing state based on buffering time provided by the present invention, and as shown in fig. 3, the foregoing step S203 specifically includes:
s301, the terminal calculates the difference value between the maximum audio PTS and the current video playing time.
S302, the terminal calculates the difference value between the maximum video PTS and the current video playing time.
S303, the terminal takes the minimum value of the difference value between the maximum audio PTS and the current video playing time and the difference value between the maximum video PTS and the current video playing time as the second buffer time of the decoding module and the subsequent module of the decoding module.
The above formula is explained below by a formula.
Assuming that the maximum audio PTS calculated by the terminal is PTS (maxaudipts), the maximum video PTS is PTS (maxvideo PTS), and the current video playing time is currposition, the decoding module and the second buffer time buffer 2 in the following module can be calculated by using the following formula (1):
buffersize2＝MIN((maxVideoPTS–curPosition),(maxAudioPTS–curPosition))(1)
specifically, taking audio as an example, the maximum audio PTS sent by the audio/video separation module to the decoding module represents the maximum data received by the decoding module and its subsequent module, and the current video playing time represents the data consumed by the decoding module and its subsequent module, and the two are subtracted from each other, so that the obtained result is the second buffering time of the decoding module and its subsequent module. For example, the maximum audio PTS sent by the audio/video separation module to the decoding module is 30 seconds, and the current video playing time is 10 seconds, that is, the video is played to the 10 th second at present, which indicates that the decoding module and the subsequent module buffer the buffering time of 20 seconds at this time.
Further, after the terminal respectively obtains the audio buffering time and the video buffering time, the smaller value is used as the final decoding module and the second buffering time of the subsequent module.
On the basis of the foregoing embodiment, the present embodiment relates to a specific method for the terminal to determine whether to continue playing the video according to the sum of the second buffering time and the first buffering time in the previous module of the decoding module, that is, one specific method of the foregoing step S204 is:
and if the sum of the second cache time and the first cache time in the previous module of the decoding module is greater than or equal to a preset buffer starting threshold value, the terminal determines to continue playing the video, otherwise, the terminal determines to pause playing the video.
Specifically, the sum of the second buffer time of the decoding module and the subsequent module of the decoding module and the first buffer time of the audio/video separation module and the previous module of the audio/video separation module is the current total buffer time of the terminal, the total buffer time of the terminal is compared with a preset buffer start threshold, and if the total buffer time of the terminal is greater than or equal to the preset buffer start threshold, the current total buffer time of the terminal is larger, the terminal does not need to be buffered, and the terminal continues to play.
If the sum of the second cache time of the decoding module and the later module of the decoding module and the first cache time of the audio/video separation module and the earlier module of the audio/video separation module is smaller than the preset buffer starting threshold value, the total cache time of the terminal is smaller, and the terminal stops playing and starts buffering.
Compared with the prior art that only the calculable cache time is compared with the preset cache start threshold value, in the embodiment, the sum of the calculable cache time and the cache time determined by the method is compared with the preset cache start threshold value, obviously, compared with the prior art, the cache time compared by the embodiment is larger, so that the number of times of buffering can be obviously reduced, and the user experience is improved.
Fig. 4 is a schematic flowchart of a first embodiment of a method for determining a video playing status based on a buffering time according to another embodiment of the present invention, as shown in fig. 4, the method includes:
s401, the terminal determines an audio and video separation module and first cache time in a previous module of the audio and video separation module.
And S402, the terminal judges whether the first cache time in the audio and video separation module and the previous module of the audio and video separation module is greater than or equal to a preset buffer starting threshold value, if so, S403 is executed, otherwise, the terminal determines whether to continue playing the video according to the method steps in the first embodiment.
And S403, the terminal determines to continue playing the video.
The above process of determining whether to pause playing of the video by the terminal may be periodically performed according to a certain time interval, and when each period starts, the terminal may first perform steps S401 to S403 in this embodiment, that is, the terminal first determines first buffer times in the audio/video separation module and its previous module, and if the buffer times are greater than or equal to a preset buffer start threshold, the terminal continues playing the video without determining a decoding module and its second buffer time in the subsequent module. And only when the first cache time of the audio and video separation module and the previous module is less than the preset buffer starting threshold value, the terminal further determines whether to pause playing the video according to the decoding module and the second cache time of the subsequent module. The processing mode can ensure that the video is directly continuously played when the cache time of the module capable of calculating the cache time is longer, so that the operation times of the terminal can be reduced, and the processing efficiency of the terminal is improved.
