In addition, features described with reference to certain examples may be combined in other examples.
As described in the background art, although a video platform in the prior art provides video streams with multiple definitions for the same video content, the video platform does not support a playing effect and playing fluency for previewing each definition in real time, and to solve at least one of the above problems, an embodiment of the present invention provides a video playing method applied to an electronic device, where the electronic device includes but is not limited to a mobile phone, a tablet computer, a notebook computer, a palm computer, a vehicle-mounted terminal, a wearable device, a pedometer, and the like. Referring to fig. 1, a video playing method according to an embodiment of the present invention includes:
step 11, receiving at least two video streams of the same video content with different resolutions, detecting a first transmission bandwidth for transmitting the at least two video streams, and determining the playing fluency of the electronic device when playing each video stream independently according to the first transmission bandwidth and the video bit rate of each video stream.
In this embodiment of the present invention, the electronic device may receive at least two video streams of the same video content, where the video streams are usually video streams of different resolutions for the same video content, and the playing of the video streams is synchronous because of the same video content, that is, the content of the first frame video picture and the content of the subsequent frames video pictures of each video stream are the same, but there is a difference in definition due to different resolutions.
In addition, while receiving the at least two video streams, the embodiment of the present invention detects a first transmission bandwidth for transmitting the at least two video streams, where the first transmission bandwidth is affected by factors such as a total bandwidth of the electronic device (the total bandwidth reflects a bandwidth capability of the device, for example, the total bandwidth of the electronic device having a 100M bandwidth network card is 100 mbits), a transmission link bandwidth between the electronic device and the network (for example, the electronic device having the 100M bandwidth network card is connected to the network through a 10M wired link, and at this time, the transmission link bandwidth is 10 mbits), and a data transmission bandwidth allocated to the electronic device by a video stream end. Typically, the first transmission bandwidth is less than or equal to a total bandwidth of the electronic device. For example, when the transmission link band and the data transmission bandwidth are not considered, if there is other data transmission between the electronic device and the network besides the at least two video streams, the first transmission bandwidth is smaller than the total bandwidth of the electronic device; whereas if there is only data transmission of the at least two video streams between the electronic device and the network, the first transmission bandwidth is typically close to or equal to the total bandwidth of the electronic device. The specific detection method of the bandwidth for transmitting the video stream may refer to implementation of the prior art, for example, the occupied bandwidth of each process may be periodically detected, and then the first transmission bandwidth may be determined according to a total bandwidth of the electronic device, or independent data reception tests may be performed on data transmitting ends corresponding to each video stream, so as to obtain bandwidths from the device to the data transmitting ends.
The embodiment of the invention can simultaneously receive at least two video streams of the same video content, and when a user actually watches videos, the user usually only selects one of the video streams with one definition, so that the problem that the user can be stuck when simultaneously receiving and playing multiple video streams but can not be stuck when only receiving and playing one video stream can exist. In order to reflect the playing fluency when a user actually watches a certain video stream, the embodiment of the present invention may process the playing fluency when the electronic device separately plays each video stream according to the following manner, where the playing stream degree may be represented by a video playing frame rate:
for each video stream:
1) and when the first transmission bandwidth is larger than or equal to the video bit rate of the video stream, determining the playing fluency when the video stream is played independently according to the original frame rate of the video stream.
Specifically, the original frame rate can be directly used as the playing fluency when the video stream is played independently. Of course, the embodiment of the present invention may also fine-tune the original frame rate according to a first difference (the first difference is a positive value) between the first transmission bandwidth and the video bit rate, and use the fine-tuned result as the playing fluency. For example, when the first difference is greater than a preset threshold, the original frame rate is taken as the playing fluency when the video stream is played alone, and when the first difference is less than the preset threshold, an adjustment amount is subtracted from the original frame rate according to the size of the first difference to obtain the playing fluency when the video stream is played alone, where the adjustment amount may be generally positively correlated with the first difference.
2) When the first transmission bandwidth is smaller than the video bit rate of the video stream, determining the playing fluency when the video stream is played independently according to the product of the original frame rate of the video stream and a first ratio, wherein the first ratio is the ratio of the first transmission bandwidth to the video bit rate.
Specifically, the product of the original frame rate and the first ratio can be directly used as the playing fluency when the video stream is played independently. Of course, the embodiment of the present invention may also perform a fine adjustment based on the product according to a second difference (the second difference is a positive value) between the video bit rate and the first transmission bandwidth, and use the fine-adjusted result as the fluency of the playing. For example, according to the magnitude of the second difference, an adjustment amount is subtracted from the product to obtain the fluency of playing the video stream alone, and the adjustment amount may be generally positively correlated with the second difference.
And step 12, playing the at least two paths of video streams in parallel, and displaying the information of the playing fluency of each path of video stream.
Here, the embodiment of the present invention may play the at least two paths of video streams in parallel on a video playing interface of the electronic device, and display information of the playing fluency (e.g., frame rate) of each path of video stream, where a specific display manner may directly display a corresponding frame rate at a preset position on a picture of each path of video stream.
Through the steps, the embodiment of the invention can intuitively display the definition and the difference of the fluency of each video stream to the user by the modes of parallel playing and displaying the playing fluency aiming at the same video content. The video streams are played synchronously, namely, the content of the picture of each video stream is the same when the video streams are played in parallel, so that convenience is brought to a user to compare the definition with the playing fluency on the basis of the content of the same picture.
As shown in fig. 2, another video playing method provided in the embodiment of the present invention includes, in addition to steps 11 to 12 shown in fig. 1, the following steps:
and step 13, receiving a selection instruction of a user for a target video stream in the at least two video streams.
Here, a user may select a desired video stream according to a requirement of the user for definition and fluency, where there are multiple specific selection manners, for example, for an electronic device with a touch screen function, one of the video frames of the multiple video streams may be selected by a touch selection manner, and a video stream corresponding to the selected video frame is a target video stream, which is not specifically limited in the embodiment of the present invention.
In addition, when the at least two video streams are played in parallel in step 12, the embodiment of the present invention may also adaptively recommend a candidate video stream to the user according to the size of the first transmission bandwidth, where the resolution of the candidate video stream is positively correlated with the first transmission bandwidth, so as to prompt the user that the candidate video stream can better adapt to the network environment in the current network environment, thereby achieving the purpose of fully utilizing the bandwidth.
Specifically, when a network is accessed through radio access networks of different Radio Access Technologies (RATs), there is a significant difference between network transmission rates. Therefore, as an implementation manner, the embodiment of the present invention may pre-define that different Radio Access Technologies (RATs) correspond to different first transmission bandwidths, for example:
A) when the electronic equipment is connected to a server corresponding to the video content through a 2G wireless access network, the first transmission bandwidth is usually very small;
B) the first transmission bandwidth is typically smaller when the electronic device is accessed via a 3G radio access network;
C) when the electronic device is accessed through the 4G wireless access network, the first transmission bandwidth is generally better;
D) the first transmission bandwidth is typically very good when the electronic device is accessed via a 5G or WIFI radio access network.
Therefore, in the cases of a) and B) above, the electronic device may select the video stream of the lowest resolution (province traffic mode) as the candidate video stream; in the case of C) above, the electronic device may select a video stream of the resolution of the intermediate gear (e.g., standard definition mode) as the candidate video stream; in the case of D), the electronic device may select a video stream with higher or highest resolution (e.g., high definition, super definition, or blu-ray mode) as a candidate video stream, and prompt the video stream as the candidate video stream in a preset display manner, for example, by highlighting a frame of the video stream or displaying prompt information on a picture of the video stream.
Of course, the user may select the candidate video stream as the target video stream by himself or may select other video streams besides the candidate video stream as the target video stream, which is not specifically limited in this embodiment of the present invention.
And step 14, according to the selection instruction, stopping playing the at least two paths of video streams in parallel, and switching to the target video stream for playing.
Here, after receiving the selection instruction, the electronic device stops playing the at least two video streams in parallel, switches to the target video stream, and receives and plays the target video stream, thereby implementing video playing desired by the user.
Through the steps, the embodiment of the invention can visually display the difference between the definition and the fluency of each video stream, is convenient for a user to select the video stream expected by the user according to the requirements of the user on the definition and the fluency of playing, and improves the use experience of the user.
In the embodiment of the present invention, when a user desires to compare multiple definitions of a certain video content, the user may actively request to acquire at least two video streams of different resolutions of the certain video content, and input a preset instruction (assumed to be a definition preview instruction) for requesting multiple video streams to the electronic device, thereby triggering the process of fig. 1/fig. 2, at this time, before step 11, the electronic device may receive the definition preview instruction input by the user, request at least two video streams of different resolutions of the certain video content according to the definition preview instruction, and then enter step 11.
In addition, in the embodiment of the present invention, the electronic device may also actively trigger the flow of fig. 1/2, for example, in a process that the electronic device plays one of the video streams (assumed as a first video stream) of the video content, if it is detected that a variation amplitude of a second transmission bandwidth for transmitting the first video stream exceeds a preset amplitude, at least two video streams with different resolutions of the video content are requested. For example, when the increasing or decreasing amplitude of the second transmission bandwidth is greater than a predetermined amplitude (e.g., 30%), the electronic device determines that the current network environment has changed greatly, and the originally played video stream may be jammed in a new network environment, or the new network environment may support playing a video stream with higher definition, and at this time, at least two video streams with different resolutions of the video content may be requested from the network, so as to better adapt to the change of the network environment and provide a video stream adapted to the current network environment.
Further, when the variation range of the second transmission bandwidth exceeds a preset range, the electronic device may further select the at least two video streams corresponding to the first transmission bandwidth according to the first transmission bandwidth, where the resolutions of the at least two video streams are positively correlated to the first transmission bandwidth. That is, when the first transmission bandwidth is large, the sum of the resolutions of the selected at least two video streams is also large, and when the first transmission bandwidth is small, the sum of the resolutions of the selected at least two video streams is also small. For example, when the first transmission bandwidth is large, the video stream with the higher resolution may be selected as the at least two video streams from all the supported resolutions, and when the first transmission bandwidth is small, the video stream with the smaller resolution may be selected as the at least two video streams.
The network environment of the electronic device changes significantly, which is usually caused by network handover, and particularly, when the electronic device is handed over to a radio access network of a different RAT, the network transmission rate changes significantly. Therefore, as an implementation manner, the embodiment of the present invention may pre-define different RATs corresponding to different first transmission bandwidths, for example, when an electronic device is connected to a server corresponding to the video content through a 2G radio access network, the first transmission bandwidth is usually small; when the electronic device is accessed through the 3G wireless access network, the first transmission bandwidth is generally smaller; when the electronic device is accessed through a 5G radio access network, the first transmission bandwidth is generally preferred; the first transmission bandwidth is typically very good when the electronic device is accessed via a 5G or WIFI radio access network. Assume that the video content has the following 5 video streams with different resolutions, which respectively correspond to: the system comprises a flow-saving mode, a standard definition mode, a high definition mode, a super definition mode and a blue light mode, wherein the resolution ratio of each mode is increased in sequence. When the electronic device is accessed through a 2G or 3G wireless access network, at this time, because the first transmission bandwidth is small, at least two video streams with small resolution are selected, for example, a traffic-saving mode and a standard definition mode can be selected as the at least two video streams; when the electronic device is accessed through the 4G wireless access network, at the moment, because the first transmission bandwidth is moderate, at least two paths of video streams with moderate resolution are selected, for example, a standard definition mode and a high definition mode can be selected as the at least two paths of video streams; when the electronic device is accessed through the 5G/WIFI wireless access network, at this time, because the first transmission bandwidth is large, at least two video streams with large resolution are selected, for example, an ultra-clear mode and a blue-ray mode may be selected as the at least two video streams. It should be noted that the above is only an example of the specific implementation of the embodiments of the present invention, and is not intended to limit the present invention.
Considering that the first transmission bandwidth may not be sufficient to support the synchronous playing of the at least two video streams, as an implementation manner, the embodiment of the present invention may perform the parallel playing by using a policy of buffering before playing when the first transmission bandwidth does not support the synchronous playing of the at least two video streams.
At this time, in the step 11, the electronic device calculates a sum of video resolutions of the at least two video streams, compares the sum with a current first transmission bandwidth of the electronic device, and determines whether the first transmission bandwidth supports synchronous playing of the at least two video streams (when the sum is greater than or equal to the first transmission bandwidth, it may be considered that synchronous playing of the at least two video streams is supported, otherwise, it is considered that the at least two video streams are not supported). When the first transmission bandwidth supports synchronous playing of the at least two video streams, the electronic device may receive the at least two video streams and perform step 12 to play the at least two video streams in parallel, and when the first transmission bandwidth does not support synchronous playing of the at least two video streams, the electronic device may receive and cache video stream data with a preset playing duration for each video stream, and perform step 12 to play the at least two video streams in parallel after the at least two video streams are cached completely.
In the step 12, the electronic device may divide a video playing interface thereof into a plurality of display areas, and divide a video picture of the video content into a plurality of sub-pictures according to positions of the plurality of display areas, where each display area corresponds to a sub-picture in one video source, and fig. 3 shows an example of a relationship between a sub-picture and a complete video picture, specifically, the video playing interface 300 in fig. 3 includes 4 display areas, which correspond to 4 sub-pictures with different definitions, respectively, a standard-definition sub-picture 301, a high-definition sub-picture 302, an ultra-definition sub-picture 303, and a blue-light sub-picture 304, where the sub-pictures are parts of the complete video picture, and together form a complete video picture. And then, rendering the sub-picture corresponding to the display area in each path of video stream to the display area corresponding to each path of video stream.
Through the steps, when the at least two video streams are played in parallel, the sub-pictures of each video stream form a complete video picture, and the resolution ratio of the sub-pictures is not reduced relative to the original video picture (the sub-pictures are part of the original video picture, and the positions and the sizes of the sub-pictures are consistent with those of the original picture), so that the actual effect of the definition when the video streams are played independently can be well reflected, and in addition, the comparison of the definition with other sub-pictures displayed in parallel is facilitated.
As another implementation manner, in the embodiment of the present invention, when the first transmission bandwidth does not support synchronous playing of the at least two video streams, only the first frame video data of the at least two video streams may be received, and then the first frame picture corresponding to the first frame video data is played in parallel, so as to perform comparison of the multiple video streams, thereby saving the receiving time of the video stream data.
At this time, in step 11, the electronic device may calculate a sum of video resolutions of the at least two video streams, and compare the sum with a current first transmission bandwidth of the electronic device to determine whether the first transmission bandwidth supports synchronous playing of the at least two video streams. And when the first transmission bandwidth supports synchronous playing of the at least two video streams, receiving the at least two video streams, and proceeding to step 12 to play the at least two video streams in parallel, and when the first transmission bandwidth does not support synchronous playing of the at least two video streams, receiving only the first frame video data of the at least two video streams, and proceeding to step 12.
In step 12, the electronic device may divide the video playing interface into a plurality of display areas, and divide the video frame of the video content into a plurality of sub-frames according to the positions of the plurality of display areas, where each display area corresponds to one sub-frame of one video source (similar to fig. 3). Then, when the first transmission bandwidth supports synchronous playing of the at least two video streams, a sub-picture corresponding to the display area in each video stream is rendered to the display area corresponding to each video stream, and when the first transmission bandwidth does not support synchronous playing of the at least two video streams, a sub-picture corresponding to the display area in a first frame picture of each video stream is rendered to the display area corresponding to each video stream, wherein the first frame picture is obtained by decoding according to the first frame data.
In the above two implementation manners, in the embodiment of the present invention, it is necessary to render the sub-picture corresponding to the display area in each video stream to the display area corresponding to each video stream, or render the sub-picture corresponding to the display area in the first frame picture of each video stream to the display area corresponding to each video stream, where specific rendering manners are various, and the following description is briefly made:
the first method comprises the following steps: adopting players with the same number as the at least two sub-pictures, wherein each player corresponds to one path of video stream; and loading and decoding each path of video stream in parallel through each player, and rendering the sub-picture corresponding to the display area in each path of video stream to the display area corresponding to each path of video stream, wherein the position coordinates of each display area are known, so that the sub-picture of each display area can be rendered to the corresponding display area respectively.
And the second method comprises the following steps: rendering and playing by adopting a player, specifically, extracting video data of a sub-picture corresponding to the display area in the video source from each path of video stream, and synthesizing the video data extracted from each path of video stream to obtain a path of new video stream; and loading and decoding the new video stream through a player, and rendering the new video stream to the video playing interface.
It should be noted that, the above is only the parallel playing mode that can be adopted by the embodiment of the present invention, and the present invention can also adopt other playing modes, and for saving space, the detailed description is not repeated here.
In addition, in addition to the parallel playing mode shown in fig. 3, the present invention may also adopt the parallel playing mode shown in fig. 4, as shown in fig. 4, the video playing interface 400 of fig. 4 includes 4 display areas, which are respectively a standard definition display area 401, a high definition display area 402, an ultra-definition display area 403, and a blue light display area 404, different from fig. 4, these display areas all display a complete video picture, and these video pictures are synchronous video streams for the same video content, so these video pictures should be the same when playing is not stuck. Thus, when the at least two video streams are played in parallel in step 12, the video playing interface may be divided into a plurality of display areas, where each display area corresponds to one video stream; and then, loading and decoding each path of video stream in parallel, and rendering to a display area corresponding to each path of video stream. For example, by a plurality of players (each player corresponds to a display area), each video stream is loaded and decoded in parallel by each player, and the video pictures of each video stream are rendered to the corresponding display area.
In addition, the display areas in fig. 3 and 4 are all the same in size and rectangular in shape, but display areas with irregular shapes may be adopted in the embodiment of the present invention, and the sizes and shapes of the display areas may be the same or different. Moreover, each display area may be displayed in a tiled manner as shown in fig. 3 or fig. 4, or may be displayed in a stacked manner (that is, there may be an overlap between the display areas), which is not specifically limited in this embodiment of the present invention.
