Detailed Description
Referring to the drawings, wherein like reference numbers refer to like elements, the principles of the present application are illustrated as being implemented in a suitable computing environment. The following description is based on illustrated embodiments of the application and should not be taken as limiting the application with respect to other embodiments that are not detailed herein.
An execution main body of the video playing method may be the video playing device provided in the embodiment of the present application, or a split electronic device integrated with the video playing device, where the video playing device may be implemented in a hardware or software manner.
Referring to fig. 1, the split electronic device is composed of a host part and a screen part, the screen part and the host part can be spliced together to form a complete electronic device, or can be split apart, but the screen part still has the function of the complete electronic device, and the host part has the function of the electronic device other than the display function, that is, the host part and the screen part cannot be displayed separately when in a split state.
Referring to fig. 2, fig. 2 is a schematic flowchart illustrating a video playing method according to an embodiment of the present disclosure. As shown in fig. 2, a flow of a video playing method provided in the embodiment of the present application may be as follows:
101. the screen portion receives a video play request input by a user and transmits the video play request to the host portion over a first communication connection between the screen portion and the host portion.
As shown in fig. 1, the screen portion and the host portion are in a split state, and the screen portion and the host portion can establish a wireless communication connection therebetween through respective wireless communication modules and/or establish a wired communication connection therebetween through respective wired communication modules. The Wireless communication module includes, but is not limited to, a Wi-Fi (Wireless Fidelity ) module, a bluetooth module, etc., and the wired communication module includes, but is not limited to, a USB (Universal Serial Bus) module, etc.
For the convenience of users, in the embodiment of the application, when the screen part is in a split state with the host part, the wireless communication connection is established through respective wireless communication modules by default. For example, the screen portion and the host portion may establish a Wi-Fi direct connection based on respective Wi-Fi modules, and may also be configured such that one of the two portions operates in an AP (Access Point) mode and the other portion operates in an STA (Station) mode, so that the one portion operating in the STA mode accesses the one portion operating in the AP mode, and so on. Of course, when the screen portion and the host portion are in the split state, the user may also use the data line to connect the wired communication modules at the two ends of the screen portion and the host portion, so that the screen portion and the host portion can establish the wired communication connection.
It should be noted that, in the embodiment of the present application, when the screen portion is in a split state with the host portion, a communication connection is maintained by default between the screen portion and the host portion, wherein the priority of the wired communication connection is higher than that of the wireless communication connection. For example, when the screen part and the host part are in a split state, the wireless communication connection between the screen part and the host part is established through respective wireless communication modules, and if the wired communication modules of the screen part and the host part are connected through the data lines, the wireless communication connection established between the screen part and the host part is disconnected, and the wired communication connection between the screen part and the host part is established through the data lines. For convenience of description, a communication connection which is maintained by default when the screen portion is in a separated state from the host portion is referred to as a first communication connection, and the first communication connection may be a wireless communication connection between the screen portion and the host portion or a wired communication connection between the screen portion and the host portion.
In the embodiment of the application, the screen part is provided with a video browsing interface, the screen part can provide a playing inlet of a video stored locally on the video browsing interface, can also access the host part through a first communication connection between the screen part and the host part, and provides a playing inlet of the video stored by the host part on the video browsing interface. The user may input a video playing request to the screen portion through the playing entry, for example, the user may click any playing entry in the video browsing interface with a finger to input the video playing request to the screen portion, and instruct the screen portion to play the video corresponding to the clicked playing entry.
After receiving a video playing request of a user, the screen part identifies a video required to be played indicated by the video playing request, and for convenience of description, the video required to be played is recorded as a target video. After identifying the target video indicated by the video play request, the screen portion further identifies whether the target video is located in the screen portion or the host portion.
If the target video is identified to be located in the screen portion, the screen portion directly plays the target video, and if the target video is identified to be located in the host portion, the video playing request is transmitted to the host portion through the first communication connection.
For example, referring to fig. 3, in the video browsing interface shown in fig. 3, the play entries 1-8 correspond to the videos locally stored in the screen portion, and the play entries 9-16 correspond to the videos locally stored in the host portion. If the user inputs a video playing request to the screen part by clicking any one of the playing entrances 1-8, the screen part determines a target video to be played from the videos stored in the screen part according to the video playing request and plays the target video on the screen part. If the user inputs a video playing request to the screen portion by clicking any one of the playing entries 9-16, the screen portion recognizes that the target video is located in the host portion according to the video playing request, and transmits the video playing request to the host portion through the first communication connection.
102. The host part determines a target video to be played according to the video playing request.
After receiving a video playing request transmitted by the screen part through the first communication connection, the host part determines a target video to be played from the locally stored videos according to the video playing request.
103. The host portion determines whether the video bitrate of the target video is greater than the available bandwidth of the first communication connection.
After determining a target video to be played, the host part further obtains a video code rate of the target video and an obtained available bandwidth of the first communication connection, wherein the video code rate describes the data volume of the video in unit time length, the unit of the video code rate is usually kbps, namely kilobits per second, and the available bandwidth describes the data volume which can be transmitted in the unit time length of the communication connection, the unit of the available bandwidth is usually Mbps, namely megabits per second. Generally, the higher the video rate of a video, the higher the quality of the video. Referring to fig. 4, the video bitrate of a video is determined by various factors, including video parameters such as the refresh frequency (in Hz, Hz), the color coding (in bit, Hz), and the resolution (located in p, pixel), wherein the video bitrate is higher when the refresh frequency is certain (e.g. 30Hz), the video bitrate is higher when the refresh frequency is higher, the video bitrate is higher when the color coding is certain (e.g. 8bit), and the video bitrate is higher when the refresh frequency is higher and/or the color coding is higher when the resolution is certain (e.g. 4K, 4096 × 2160 p).
Based on the above description, it can be understood by those skilled in the art that when the video bitrate of the target video is greater than the available bandwidth of the first communication connection, it indicates that the screen portion cannot acquire the data of the target video in one unit duration through the first communication connection in one unit duration, that is, the screen portion cannot realize "online playing" of the target video in the host portion, and when the video bitrate of the target video is less than or equal to the available bandwidth of the first communication connection, it indicates that the screen portion can acquire the data of the target video in one unit duration through the first communication connection in one unit duration, that is, the screen portion can realize "online playing" of the target video in the host portion. Therefore, after the host part acquires the video code rate of the target video and the acquired available bandwidth of the first communication connection, whether the video code rate of the target video is larger than the available bandwidth of the first communication connection is judged, and whether the screen part can realize the online playing of the target video in the host part is determined according to the obtained judgment result.
104. If so, the host portion establishes a second communication connection with the screen portion and transmits the target video to the screen portion through the first communication connection and the second communication connection.
In the embodiment of the application, if the judgment result obtained by the host part is yes, that is, the video code rate of the target video is greater than the available bandwidth of the first communication connection, the host part determines that the target video in the host part cannot be played on line on the screen part. At this time, the host portion establishes a second communication connection with the screen portion other than the first communication connection. Wherein the second communication connection is a wireless communication connection if the first communication connection is a wired communication connection, or the second communication connection is a wired communication connection if the first communication connection is a wireless communication connection.
For example, if the first communication connection established by the screen portion and the host portion is a wired communication connection, the host portion and the screen portion establish a wireless communication connection based on the respective wireless communication modules, and the wireless communication connection is taken as a second wireless communication connection.
For another example, if the first communication connection established between the screen portion and the host portion is a wireless communication connection, the host portion transmits a prompt message prompting the user to connect the screen portion and the host portion using the data line to the screen portion via the first communication connection, and instructs the screen portion to display the prompt message. The host portion establishes a wired communication connection with the screen portion based on the respective wired communication modules when the host portion accesses the data line between the host portion and the screen portion, and the wired communication connection is made as a second wireless communication connection.
The host portion transmits data of the target video to the screen portion in parallel through the first communication connection and the second communication connection after establishing the second communication connection with the screen portion.
105. The screen portion plays the target video.
And the screen part receives partial data of the target video in the transmission process of the target video, and plays the partial data until the transmission and the playing of all data of the target video are finished, so that the online playing of the target video is realized.
As can be seen from the above, in the embodiment of the present application, for the split electronic device in which the screen portion and the host portion are in the split state and the first communication connection is established, the video playing request received by the screen portion may be first obtained, and according to the video playing request, the target video to be played is determined from the video stored in the host portion, and then it is determined whether the video bitrate of the target video is greater than the available bandwidth of the first communication connection, if so, the second communication connection is established between the screen portion and the host portion, so that the target video is transmitted to the screen portion through the first communication connection and the second communication connection, and the target video is played through the screen portion.
In one embodiment, "transmitting a target video to a screen portion through a first communication connection and a second communication connection" includes:
(1) the host part acquires the ratio of available bandwidth between the first communication connection and the second communication connection;
(2) the host part determines a distribution proportion for distributing the target video to the first communication connection and the second communication connection for transmission according to the obtained ratio;
(3) and the host part distributes the target video to the first communication connection and the second communication connection for transmission according to the distribution ratio.
In the embodiment of the application, when the host part transmits the target video to the screen part through the first communication connection and the second communication connection, the host part firstly acquires the available bandwidth of the second communication connection, and further acquires the ratio of the available bandwidth between the first communication connection and the second communication connection according to the available bandwidth of the first communication connection acquired before.
After the ratio of the available bandwidth between the first communication connection and the second communication connection is obtained, the host part further determines a distribution ratio for distributing the target video to the first communication connection and the second communication connection for transmission according to the obtained ratio, wherein the distribution ratio is used for describing how much of the total data volume of the target video is distributed to the first communication connection for transmission and how much of the total data volume of the target video is distributed to the second communication connection for transmission.
Where the ratio of the available bandwidth between the first communication connection and the second communication connection is a/B, the allocation ratio may be determined as (a/(a + B) × 100%, B (a + B) × 100%), where the allocation ratio indicates that "a/(a + B)" percent of data in the target video is allocated to the first communication connection for transmission and "B/(a + B)" percent of data in the target video is allocated to the second communication connection for transmission.
For example, assuming that the ratio of available bandwidth between the first communication connection and the second communication connection is 2/3, the allocation ratio may be determined to be (40%, 60%) indicating that 40% of the data in the target video is to be allocated for transmission on the first communication connection and 60% of the data in the target video is to be allocated for transmission on the second communication connection.
The host portion may assign the target video to the first communication connection and the second communication connection for transmission according to the determined assignment ratio after determining the assignment ratio for assigning the target video to the first communication connection and the second communication connection for transmission. For example, assuming that the total amount of data of the target video is 1000MB, and assuming that the determined distribution ratio is (40%, 60%), the host portion distributes 400MB of data in the target video to the first communication connection for transmission, and distributes 600MB of data in the target video, except for the previous 400MB of data, to the second communication connection for transmission.
In one embodiment, the "host part allocates the target video to the first communication connection and the second communication connection for transmission according to the allocation ratio" includes:
(1) the host part divides the target video into a plurality of video segments which are connected in sequence;
(2) and the host part divides each video clip into two sub-video clips in sequence according to the determined distribution proportion according to the sequence of each video clip, and transmits the two sub-video clips through the first communication connection and the second communication connection respectively.
In the embodiment of the application, when the host part allocates the target video to the first communication connection and the second communication connection for transmission, the host part can split the target video into a plurality of video segments according to a preset splitting rule. For the setting of the splitting rule, the embodiment of the present application is not particularly limited, for example, the splitting rule may be configured as: the target video is split into a plurality of video segments which have unit time length (such as 1 second) and are connected in sequence.
After splitting the target video into a plurality of video segments which are sequentially connected, the host part sequentially splits each video segment into two sub-video segments according to the determined distribution proportion according to the sequence of each video segment, and transmits the two sub-video segments through the first communication connection and the second communication connection respectively.
Illustratively, assuming that the target video has a duration of 100 seconds and a determined allocation ratio is (40%, 60%), the target video is split into 100 video segments with a duration of 1 second by the host portion, and then, for a first video segment, the host portion splits the target video into a sub-video segment with a duration of 0.4 second and a sub-video segment with a duration of 0.6 second, and allocates the sub-video segment with a duration of 0.4 second to the first communication connection for transmission, and allocates the sub-video segment with a duration of 0.6 second to the second communication connection for transmission, and accordingly, after the screen portion receives the two sub-video segments through the first communication connection and the second communication connection respectively, the host portion merges the two sub-video segments received by the screen portion into the first video segment for playing, so that the host portion transmits all the video segments obtained by splitting the target video to the screen portion, and the screen part plays the video, so that the screen part can play the target video in the host part on line.
In an embodiment, a video playing method provided in an embodiment of the present application further includes:
(1) the host part acquires a first packet loss rate of the first communication connection and a second packet loss rate of the second communication connection in the process of transmitting the video clip;
(2) and the host part adjusts the distribution proportion according to the acquired first packet loss rate and the acquired second packet loss rate.
In the process of transmitting the target video, the host part performs statistics on the packet loss rate of the first communication connection according to a preset statistical period (which is not specifically limited in the embodiment of the present application and can be set by a person skilled in the art according to actual needs, for example, the statistical period can be set to 5 seconds), obtains the first packet loss rate of the first communication connection, performs statistics on the packet loss rate of the second communication connection, and obtains the second packet loss rate of the second communication connection.
After the first packet loss rate of the first communication connection and the second packet loss rate of the second communication connection are obtained in each statistical period, the host part may compare the first packet loss rate and the second packet loss rate, and if the first packet loss rate is larger, reduce the percentage of the first communication connection in the distribution ratio according to a preset adjustment amount (which is not specifically limited in this embodiment and may be set by a person skilled in the art according to actual needs, for example, may be set to 5%), and correspondingly increase the percentage of the second communication connection in the distribution ratio according to the preset adjustment amount. Accordingly, after the host part completes the adjustment of the distribution proportion, the transmission of the video segments can be controlled according to the adjusted distribution proportion.
For example, assuming that the allocation ratio is (40%, 60%) and the preset adjustment amount is 5%, if the host part determines that the first packet loss rate of the first communication connection is greater than the second packet loss rate of the second communication connection, the allocation ratio is adjusted to (35%, 65%).
By periodically adjusting the allocation ratio, the real-time allocation ratio can be adapted to the network conditions of the first communication connection and the second communication connection, thereby ensuring the stability of data transmission.
In one embodiment, before "transmitting the target video to the screen portion through the first communication connection and the second communication connection", the method further includes:
(1) the host part acquires the sum value of the available bandwidth of the first communication connection and the second communication connection;
(2) the host part judges whether the video code rate of the target video is greater than the sum value;
(3) and if not, the host part transmits the target video to the screen part through the first communication connection and the second communication connection.
In order to ensure that the target video can be transmitted to the screen part through the first communication connection and the second communication connection by the host part, so as to realize the online playing of the target video in the host part by the screen part, the host part firstly acquires the available bandwidth of the second communication connection after completing the establishment of the second communication connection between the screen part and the host part, and further acquires the sum of the available bandwidths of the first communication connection and the second communication connection according to the acquired available bandwidth of the first communication connection.
After acquiring the sum of the available bandwidths of the first communication connection and the second communication connection, the host part further judges whether the video code rate of the target video is larger than the acquired sum, wherein, when the video code rate of the target video is greater than the sum, it means that the screen portion cannot acquire the data of one unit duration of the target video through the first communication connection and the second communication connection within one unit duration, that is, the screen portion cannot realize the "online playing" of the target video in the host portion, when the video code rate of the target video is less than or equal to the sum, it is indicated that the screen portion can acquire data of one unit duration of the target video through the first communication connection and the second communication connection within one unit duration, that is, the screen portion can realize "online playing" of the target video in the host portion.
Further, if the judgment result obtained by the host part is negative, that is, the video code rate of the target video is less than or equal to the sum of the available bandwidths of the first communication connection and the second communication connection, the host part determines that the online playing of the target video in the host part can be realized in the screen part. At this time, the host portion transmits the target video to the screen portion through the first communication connection and the second communication connection, so as to play the target video on line through the screen portion.
In an embodiment, after the "the host part determines whether the video bitrate of the target video is greater than the sum", the method further includes:
(1) if so, the host part re-encodes the target video to obtain a first re-encoded video, wherein the video code rate of the first re-encoded video is less than or equal to the sum;
(2) the host part outputs the first recoded video to the screen part through the first communication connection and the second communication connection;
(3) and the screen part plays the first recoded video.
After the host part judges whether the video code rate of the target video is greater than the sum, if so, that is, when the video code rate of the target video is greater than the sum of the available bandwidths of the first communication connection and the second communication connection, the host part determines that the target video in the host part cannot be played on line on the screen part.
