These terms are only used to distinguish one type of information from another. For example, a first aspect may be termed a second aspect, and, similarly, a second aspect may be termed a first aspect, without departing from the scope of one or more embodiments of the present application. The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination", depending on the context.
First, the noun terms to which one or more embodiments of the present application relate are explained.
Video streaming: a transport stream of audio and video data, the video stream being capable of being transmitted as a steady continuous stream over a network to a viewer so that the viewer can view the video.
Code rate: when video data is transmitted, the higher the code rate is, the clearer the video picture is, and the lower the code rate is, the more fuzzy the video picture is.
Frame rate: the measure for measuring the number of display frames, i.e. the refresh rate, is measured in units of number of display frames per second.
Default sharpness: when a viewer watches a video, the video provider defaults to video streams with different bit rates, i.e., different definitions, assigned to the user.
Original painting: the original video stream pushed by the video provider.
Code stream conversion: the original video stream is optimized by the algorithm for the transcoding system, the same viewing experience is kept as much as possible, and the code rate is reduced.
In the existing video watching system, a video stream is divided into an original stream and a transcoding stream, when a user watches a video through a client, the client pulls the video stream of the video, and a video file of the video is obtained by analyzing the video stream, so that the user watches the video. However, different user clients use different bandwidths, that is, the network speeds are distinguished, so that the video provider transcodes the video stream to produce video streams with different code rates, for example, an original picture video stream is converted into a high-definition video stream with a low code rate, an ultra-definition video stream, and the like, so that the user can select corresponding definition according to the network speed, the live broadcast card of the user can be effectively reduced to make the playing smoother, and the bandwidth cost of the video provider can be reduced.
However, in practical applications, when a user wants to watch a video with higher definition, the user often has a video jam and poor watching experience due to low bandwidth, poor network speed, and the like of the user, and therefore, a video provider needs to actively solve the above problem for the user and provide a better watching environment for the user.
In view of this, in the present application, a video playing method is provided, and the present application simultaneously relates to a video playing apparatus, a computing device, and a computer readable storage medium, which are described in detail in the following embodiments one by one.
Fig. 1 shows a flowchart of a video playing method according to an embodiment of the present application, which specifically includes the following steps:
step 102: receiving a window adjusting instruction of an initial video, wherein the window adjusting instruction is used for adjusting the window size of the initial video.
The initial video may be understood as a video currently being watched by a user, the window adjustment instruction may be understood as an instruction to adjust a window of the initial video, the window adjustment instruction may include window information that is desired to be adjusted, and the window of the initial video may be adjusted to a window size desired by the user according to the window adjustment instruction, for example, when the window of the initial video is 800 × 600, and the user wants to watch 1440 × 900 video, the window adjustment instruction may be issued to the user client, and the user client adjusts the initial video to 1440 × 900 windows after receiving the window adjustment instruction.
In practical application, under the condition that the code rate of the video is the same, that is, the definition is unchanged, the larger the window is, the more blurred the video watched by the user is, and correspondingly, under the condition that the window is unchanged, the higher the code rate of the video is, the clearer the video watched by the user is, but due to the improvement of the code rate of the video, the relative bandwidth requirement on the user is also improved.
Based on the above, the application provides a video playing method, which reduces video code rate and provides a video stream with less bandwidth consumption for a user when the user watches the video in a windowed manner, and switches the video stream to a video stream with higher image quality when the user watches the video in a full screen manner, wherein although the video stream code rate is low when the user watches the video in the windowed manner, the definition impression of the user is not changed due to the windowed playing; when the user watches in a full screen mode, the video stream with higher image quality is provided for the user, and the watching experience of the user is not influenced.
In a specific embodiment of the present application, when a user watches the video a, the user clicks the window adjustment button if the user wants to adjust the window size of the video a, the user client receives the window adjustment instruction at this time, and after receiving the window adjustment instruction, the user client adjusts the window of the video a to a size that the user wants to watch, that is, the window of the video a is adjusted to a size of a watching window desired by the user.
In practical application, when a user watches a video through a webpage, the user clicks the video, a watching instruction for the video to be watched is sent to the user client, and the user client provides the video to be watched for the user after relevant processing.
Specifically, before receiving a window adjustment instruction of an initial video, the method further includes:
receiving a watching instruction corresponding to a video to be watched;
acquiring a default video stream address of the video to be watched according to the watching instruction;
and playing the video to be watched based on the default video stream address.
The video to be watched can be understood as a video to be watched by the user, the watching instruction can be understood as an instruction for watching the video to be watched, the watching instruction may carry identification information of the video, and the user client provides a playing function of the video to be watched for the user after receiving the watching instruction.
The default video stream address can be understood as a video stream address of a default watching video provided by a video provider for a user, and a user client can pull the corresponding video stream according to the video stream address. For example, when a user watches a video through a web page, a high-definition (code rate 1500) video with a window size of 800 × 600 is provided for the user by default, and the user client can acquire a video file of the video to be watched according to the default video stream, so as to play the video file for the user.
In a specific embodiment of the present application, following the above example, when a user prepares to watch a video a through a web page, the user clicks a play button of the video a, at this time, the user client receives a watching instruction for the video to be watched, the user client obtains a default video stream address of the video to be watched according to the watching instruction, and according to the default video stream, the user client plays the video a in a window with a default size, where a bitrate of the video a is 1500 kilobits per second (kbps).
In practical application, a user client obtains a default video stream address through a server, and specifically, obtains the default video stream address of a video to be watched according to the watching instruction, including:
generating a viewing request according to the viewing instruction, and sending the viewing request to a server;
receiving a set of video stream addresses sent by the server in response to the viewing request;
determining a default video stream address in the set of video stream addresses according to the viewing instruction.
The watching request can be understood as a request for the user client to watch the video to be watched, after the user client receives the watching instruction, the watching request is sent to the server, the watching request can carry user client identification information, bandwidth information of the user client, video identification information and the like, and based on the watching request, the server sends a video stream address corresponding to the video to be watched to the client, so that the client can play the video to be watched.
In practical application, a plurality of video stream addresses of a video are available, the code rates corresponding to different video stream addresses are different, and after receiving an original stream of the video, a server transcodes the original stream into a plurality of transcoding streams according to the original stream, for example, a standard definition (code rate 800), a high definition (code rate 1500), an ultra-definition (code rate 2500), and a blue light (code rate 4000), where the transcoding streams can be understood as a one-pressure video stream, so that a user client can select and play a video stream with a proper code rate according to a current bandwidth; in addition, the server can perform secondary compression on each code rate to generate a two-pressure video stream corresponding to each code rate, so that the video stream with less bandwidth consumption is provided for the user client when the video is played in a window mode, the user cannot be jammed when watching the video, and the video quality is not reduced in the sense of the user.
In a specific embodiment of the application, a user client generates a viewing request according to a viewing instruction, and sends the viewing request to a server, after receiving the viewing request, the server sends a video stream address set of a video a to the user client, the video stream address set includes a high-definition, super-definition, original-drawing primary-pressure video stream address and a high-definition, super-definition, original-drawing secondary-pressure video stream address, and the user client determines a default video stream address in the video stream address set according to the viewing instruction, that is, selects a video stream address corresponding to a code rate in a window with a default size, so as to provide a video stream address with the best viewing experience and no pause phenomenon for a user in the window.
Specifically, determining a default video stream address in the set of video stream addresses according to the viewing instruction includes:
acquiring default window information of the video to be watched according to the watching instruction;
and determining a default video stream address according to the default window information.
The default window information may be understood as a default window of a video when a user watches the video, for example, when the user opens a video to be watched, the user client may provide the video with a default window for the user client to play, and may be understood as a default window size provided by the user client for the user client to play.
In practical application, a user client determines a default video stream address according to default window information, the image quality of a video played under a window corresponding to the default video stream address is clear, and the phenomenon of playing blockage cannot occur, so that the user client can be understood as a video stream address with better live broadcast viewing experience provided for a user under the condition that the bandwidth and the window are fixed.
In a specific embodiment of the present application, a user client obtains default window information of a video to be watched according to a watching instruction, where the default window information is 1280 × 1024, and the user client determines a video stream address with a default video stream address of a bitrate 1500 according to the default window information, and the video stream address can be a two-pressure video stream address corresponding to a high definition bitrate due to windowed watching. Compared with a high-definition-code-rate one-pressure video stream address, the code rate of a two-pressure video stream address is reduced, but the watching experience of a user is unchanged under the condition of watching in a windowing mode.
Step 104: and determining target window information and a target video stream address according to the window adjusting instruction.
In the process of watching a video by a user, if the user adjusts the window of the video, the user client needs to determine a video stream address again according to the window expected by the user, so as to provide the video with clearer picture quality for the user, and therefore the watching experience of the user cannot be influenced.
The target window information may be understood as video window information desired by a user, that is, a window of a video after window adjustment, and the target video stream address may be understood as a video stream address corresponding to the video in the target window information.
In practical application, under the condition that a user watches in a windowed manner, a user client determines the image quality of a video according to the size of a window, namely the window determines the code rate of a video stream, so that under the condition of window adjustment, the user client can re-determine a video stream address suitable for the code rate of the current window, and a video stream address without blockage is provided for the user to play under the condition that the image quality watched by the user is not influenced.
In a specific embodiment of the present application, along with the above example, the user client determines that the target window information is 1440 × 900 according to the window adjustment instruction, and the target video stream address is an address of an ultra-clear video stream.
Specifically, determining the target window information and the target video stream address according to the window adjustment instruction includes:
acquiring target window information in the window adjusting instruction;
determining video code rate information corresponding to the target window information according to the target window information;
and determining a target video stream address according to the video code rate information.
In practical application, a user client obtains target window information carried in a window adjustment instruction, determines video code rate information corresponding to the target window information according to the target window information, and can determine a corresponding target video stream address according to the video code rate information.
In a specific embodiment of the present application, along the above example, target window information in the window adjustment instruction is obtained, where the target window information is 1440 × 900, the video bitrate information corresponding to the target window information is determined to be super-resolution (bitrate 2500) according to the target window information, and the video stream address corresponding to the video stream with the target video stream address of bitrate 2500 is determined according to the video bitrate information.
Specifically, determining a target video stream address according to the video bitrate information includes:
determining a target video stream address set corresponding to the video code rate information according to the video code rate information, wherein the target video stream address set comprises at least one video stream address, and the coding strategies of video streams corresponding to the video stream addresses are different;
and determining a target video stream address in the target video stream address set according to the target window information.
The video streams corresponding to the video stream addresses in the target video stream address set have the same corresponding video code rate information, but the coding strategies of the video streams corresponding to the video addresses are different.
In practical application, a server provides a first-pressure video stream address and a second-pressure video stream address for a user client, the user client can select a video stream with a code rate corresponding to a target window, and can also determine whether the first-pressure video stream address or the second-pressure video stream address is used according to target window information, and the second-pressure video stream is compared with the first-pressure video stream.
Specifically, determining a target video stream address in the target video stream address set according to the target window information, further includes:
under the condition that the target window information is the maximum window of the equipment, selecting a video stream pressing address as a target video stream address in the target video stream address set;
and under the condition that the target window information is a non-equipment maximum window, selecting a two-pressure video stream address as a target video stream address from the target video stream address set.
The target window information is the maximum window of the equipment, which can be understood as that a user switches the window to the full screen, and under the condition of full screen watching, a higher-definition one-press video stream address is provided for the user to carry out pull stream playing; the condition that the target window information is a non-equipment maximum window can be understood that the user watches through windowing, and under the condition of windowing watching, the stream is pulled through a two-pressure video stream address, so that a video with no difference in image quality is played for the user.
In practical application, a user can adjust a window of a video, a user client can dynamically adjust the code rate of a video stream according to the window, and select a primary-pressure video stream or a secondary-pressure video stream under the relative code rate according to whether the window is the maximum window of the device, so that the optimal viewing experience is provided for the user by dynamically adjusting the video code rate.
In a specific embodiment of the present application, along with the above example, when the target window is the maximum window of the device, a compressed video stream address of the code rate corresponding to the target window is selected for performing pull stream playing.
In another specific embodiment of the present application, along with the above example, in the case that the target window is a non-device maximum window, the address of the two-pressure video stream with the code rate corresponding to the window is selected for performing pull-stream playing.
Specifically, when the target window information is a non-device maximum window, determining a target video stream address in the target video stream address set according to the target window information, further comprising:
determining at least two compressed video stream addresses in the target video stream address set according to the target window information;
and determining a target video stream address in the at least two compressed video stream addresses according to the attribute information of the user client.
In an actual application, the compressed video stream may be a 264 video stream or a 265 video stream, the 264 video stream is obtained by compressing the video stream through an h.264 coding compression strategy, and the 265 video is obtained by compressing the video stream through an h.265 coding compression strategy, where a specific compression strategy is determined according to an actual situation, and the application is not particularly limited herein.
In practical applications, the compressed video stream is determined according to the video stream that the device can support playing, for example, if a part of the device can only support parsing 264 video stream, the address of the 264 video stream is determined as the target video stream address. In the implementation, it is determined preferentially whether the device can support the analysis of the 265 video stream, and if the device does not support the analysis of the 265 video stream, the 264 video stream is selected for pull-stream playing.
In a specific embodiment of the present application, following the above example, when the target window is not the maximum window of the device, the user client determines two compressed video stream addresses corresponding to the target window in the target video stream address set, which are the 264 video stream address and the 265 video stream address respectively, and determines that the 265 video stream address is the target video stream address according to the attribute information of the user client.
Step 106: and switching the initial video stream address of the initial video to the target video stream address.
After the user client determines the target video stream address, the initial video stream address of the initial video currently being played can be switched to the target video stream address, and the playing is performed according to the target video stream.
In practical application, when the user client switches the video stream address, the playing progress information of the initial video is acquired at the same time, so that after the video stream address is switched to the target video stream address, when the video is played according to the target video stream address, the user can continue to watch the same video progress, and the watching experience of the user is guaranteed.
In a specific embodiment of the present application, along with the above example, the user client determines that the target video stream address is an ultraclear secondary video stream address, and plays the video according to the secondary video stream address.
Step 108: and playing a target video corresponding to the target window information based on the target video stream address, wherein the initial video and the target video have the same playing content and different code rates.
The target video can be understood as a video which is played in a pull stream mode based on a target video stream address, the target video and the initial video are the same video, namely the playing content is the same, but the code rates are different, namely the definition is different.
In practical application, the user client can perform pull-stream playing on the target video based on the target video stream address, and the target video can continue to be played according to the playing progress of the initial video.
In a specific embodiment of the present application, following the above example, the user client plays the target video corresponding to the target window information based on the target video stream address, and the playing contents of the target video and the initial video are both video a, but the code rates of the target video and the initial video are different.
Specifically, playing the target video corresponding to the target window information based on the target video stream address includes:
acquiring and analyzing a target video stream according to the target video stream address;
and playing the target video according to the analysis result and the target window information.
In practical application, a user client can acquire a video stream according to a target video stream address, and play the video stream for a user by analyzing the video stream.
In a specific embodiment of the present application, along with the above example, the user client obtains a target video stream according to a target video stream address, where the target video stream is an ultra-clear video stream, and the user client parses the target video stream and plays the target video stream with a target window, that is, plays the target video stream with a video size adjusted by the user.
The application provides a video playing method, which is characterized in that the method is applied to a user client and comprises the following steps: receiving a window adjusting instruction of an initial video, wherein the window adjusting instruction is used for adjusting the window size of the initial video; determining target window information and a target video stream address according to the window adjusting instruction; switching an initial video stream address of the initial video to the target video stream address; and playing a target video corresponding to the target window information based on the target video stream address, wherein the initial video and the target video have the same playing content and different code rates. By dynamically adjusting the definition of the played video according to the window of the video, the video with proper image quality is provided for the user under the condition of poor network of the user, the watching experience of the user is optimized, and the bandwidth cost of a video provider is reduced.
In the following, with reference to fig. 2, the application of the video playing method provided in the present application in watching live broadcast is taken as an example to further explain the video playing method. Fig. 2 shows a processing flow chart of a video playing method applied to watching live broadcast according to an embodiment of the present application, which specifically includes the following steps:
