The embodiment of the invention provides a multimedia file playing method and electronic equipment, which are used for solving the technical problem that a plurality of pieces of electronic equipment cannot play media files synchronously and achieving the technical effect that the plurality of pieces of electronic equipment can play the media files synchronously.
In order to solve the technical problems, the general idea of the embodiment of the present application is as follows:
obtaining a multimedia file;
obtaining a first playing instruction;
based on the first playing instruction, the media player of the first electronic equipment is used for a first compensation time T1Playing the multimedia file after the multimedia file arrives, wherein the first compensation time T1Equal to the delay time D1And the waiting time W is the time for waiting the second electronic equipment to synchronously play the multimedia file.
That is, in the present application, when the electronic device needs to synchronously play the same multimedia file with other electronic devices, the electronic device only needs to wait for the other electronic devices to synchronously play the multimedia file based on the delay time of the electronic device, and the technical effect of synchronously playing the same multimedia file with other electronic devices can be achieved.
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the technical solutions of the present invention. All other embodiments obtained by a person skilled in the art without any inventive work based on the embodiments described in the present application are within the scope of the protection of the technical solution of the present invention.
Example one
Referring to fig. 1, a method for playing a multimedia file according to an embodiment of the present application includes:
s101: obtaining a multimedia file;
s102: obtaining a first playing instruction;
s103: based on the first playing instruction, the media player of the first electronic equipment is used for a first compensation time T1Playing the multimedia file after the multimedia file arrives, wherein the first compensation time T1Equal to the delay time D1And the waiting time W is the time for waiting the second electronic equipment to synchronously play the multimedia file.
In a specific implementation process, the method may be applied to an electronic device provided with a media player, such as an electronic device like a mobile phone and a tablet computer, but not limited thereto, in the embodiment of the present application, a specific implementation process of the method in the embodiment of the present application is described in detail by taking a mobile phone as an example.
When the method in the embodiment of the present application is used for processing, step S101 is executed first, and a multimedia file is obtained.
In the specific implementation process, the above example is continued, and in practical applications, the mobile phone may obtain various types of multimedia files such as music files, video files and the like that need to be played, for example, when the mobile phone needs to be used as a sound of a home theater, the mobile phone may obtain the video files that need to be played from a television device through a data line or a network, when the mobile phone needs to play the music files or the video files on the network, the mobile phone may directly obtain corresponding multimedia files and the like from the network, and when the mobile phone is in network sharing with other electronic devices, the mobile phone may also obtain the multimedia files shared by other electronic devices through the network sharing.
After step S101, the method in the embodiment of the present application performs step S102, that is, obtains a first playing instruction.
In the specific implementation process, continuing with the above example, after the mobile phone obtains the multimedia file to be played, the mobile phone may obtain the playing instruction for playing the multimedia file, in practical applications, when the mobile phone needs to play the obtained multimedia file synchronously with other electronic devices, such as other mobile phones, the playing instruction obtained by the mobile phone is a synchronous playing instruction, and for convenience of description, the other mobile phones are called as second mobile phones, for example, in a situation where the mobile phone and the second mobile phone are in hotspot sharing or other network sharing situations, and the mobile phone needs to play the music file downloaded from the network by the mobile phone in synchronization with the second mobile phone, then after the mobile phone downloads the music file from the network, the mobile phone may obtain the synchronous playing instruction for playing the music file in synchronization with the second mobile phone, and of course, in practical applications, the same application software may be installed in advance on the mobile phone and the second mobile phone that needs to play synchronously with the mobile phone, so that the handset and the second handset can download the multimedia file to be synchronized from the network through the same application software.
Under the situation that the mobile phone is used as a multimedia terminal for playing, if the mobile phone and the second mobile phone are required to be used as a sound of a home theater, the video file obtained by the mobile phone from the television equipment is synchronously played, and then the video file is played by taking the mobile phone and the second mobile phone as different sound channels of the home theater, so that when surround sound is formed, the mobile phone can obtain a synchronous playing instruction for synchronously playing the video file with the second mobile phone; in the instant messaging scenario, if a second mobile phone nearby is selected by the mobile phone and a music file on the local database of the mobile phone needs to be played synchronously with the second mobile phone, the mobile phone will obtain a synchronous playing instruction that the music file needs to be played synchronously with the second mobile phone.
Of course, in practical applications, there are also cases where: when the mobile phone obtains the multimedia file to be played, the mobile phone does not synchronously play the obtained multimedia file with other electronic equipmentThe body file is played according to the conventional playing flow, and at this time, after the mobile phone performs step S101, the mobile phone performs the following steps: for convenience of description, the playing instruction is referred to as a second playing instruction, for example, after the mobile phone downloads a music file from a network, the music file needs to be played separately according to the conventional flow, the mobile phone obtains the second playing instruction that the mobile phone plays the music file separately, and for example, when the mobile phone obtains a video file from the local database, the video file needs to be played separately according to the conventional flow, and the mobile phone obtains the second playing instruction that the mobile phone plays the video file separately. Then, the mobile phone will execute the following steps: based on the second playing instruction, at a second compensation time T2Playing the multimedia file after the multimedia file arrives, wherein the second compensation time T2Is equal to the delay time D1。
In practical applications, when a mobile phone plays a multimedia file, a playing delay exists in the processes of starting system playing, decoding the multimedia file, transmitting multimedia file data to underlying hardware, and the like, and finally, a sound of the multimedia file is played through a microphone of the mobile phone or an image of the multimedia file is displayed through a display screen of the mobile phone, and the playing delay time of different mobile phones is different due to differences of hardware or/and software of the mobile phones.
It is assumed that the delay time from the beginning of system playing, the process of decoding the multimedia file, and transferring the multimedia file data to the underlying hardware, etc. of the mobile phone in this embodiment, to the end of playing the sound of the multimedia file through the mobile phone microphone or displaying the image of the multimedia file through the display screen of the mobile phone is D1Then, after the mobile phone obtains the second playing instruction for the mobile phone to play the music file alone, the media player in the mobile phone will be at the second compensation time T2After the audio signal arrives, the audio signal corresponding to the music file is played through the microphone, that is, the media player in the mobile phone waits for the delay time D1Then, playing out the sound signal corresponding to the music file through the microphone, and the second compensation time T2Is equal to the delay time D1。
Similarly, if the mobile phone obtains the second playing instruction that the mobile phone plays a video file alone, the media player in the mobile phone will delay the time D required for playing the video file in the mobile phone1And then, playing an image signal corresponding to the video file through a display screen of the video file.
After the step S102 is executed, the method in the embodiment of the present application executes the step S103, that is, based on the first playing instruction, the media player of the first electronic device performs the first compensation time T1Playing the multimedia file after the multimedia file arrives, wherein the first compensation time T1Equal to the delay time D1And the waiting time W is the time for waiting the second electronic equipment to synchronously play the multimedia file.
In a specific implementation process, the above example is continued, specifically, when the mobile phone and the second mobile phone are in a hotspot sharing scenario, and after the mobile phone obtains a synchronous playing instruction that the music file downloaded from the network by the mobile phone needs to be played synchronously with the second mobile phone, the mobile phone will use the media player in the mobile phone at a compensation time T according to the obtained synchronous playing instruction1After the music file arrives, the sound information corresponding to the music file is played, and the compensation time T is1The method comprises the steps that the mobile phone starts to play from a mobile phone system, the delay time from the decoding of a multimedia file to the transmission of multimedia file data to bottom layer hardware is D, and finally the sound corresponding to the music file is played through a mobile phone microphone1And the waiting time W for the mobile phone to wait for the second mobile phone to synchronously play the music file.
Specifically, after the mobile phone obtains a synchronous playing instruction of a video file obtained by the mobile phone from the television equipment and synchronously playing the video file, which is required to be used as a sound of the home theater with the second mobile phone, the mobile phone can also play the video file at a compensation time T through a media player in the mobile phone according to the obtained synchronous playing instruction1After the video file arrives, the sound corresponding to the video file is playedInformation, this compensation time T1The method comprises the steps that the delay time from the playing of a mobile phone system by the mobile phone is D, the delay time from the decoding of a multimedia file to the transmission of multimedia file data to bottom layer hardware is D, and finally, an image corresponding to a video file is played through a display screen of the mobile phone1And the waiting time W for the mobile phone to wait for the second mobile phone to synchronously play the video file.
Referring to fig. 2, in practical applications, before step S103, the following steps may be performed:
s201: synchronizing the delay time D of the second electronic device2；
S202: obtaining the delay time D of the first electronic device1；
S203: the wait time W is determined based on a predetermined policy.
In the implementation process, continuing with the above example, in practical applications, steps S201 to S203 executed before step S103 may be specifically executed to perform step S101: before a multimedia file is obtained, the mobile phone can obtain a multimedia file such as a music file played by the mobile phone before the multimedia file which needs to be synchronized with the second electronic device is obtained, when the video file is played, the mobile phone starts playing from a mobile phone system, and finally has a delay time D from playing a sound signal corresponding to the multimedia file through a mobile phone microphone or playing an image signal corresponding to the multimedia file through a mobile phone display screen through the processes of decoding the multimedia file, transmitting multimedia file data to underlying hardware and the like1I.e. the delay time D of playing caused by the hardware or/and software of the mobile phone itself1And obtaining the playing delay time D of the second mobile phone caused by the hardware or/and software of the second mobile phone2And then determining the waiting time W for the mobile phone to wait for the second mobile phone to synchronously play the multimedia file according to a preset strategy.
Of course, in practical applications, steps S201 to S203 executed before step S103 may also be specifically executed after step S102: executing the first playing instruction before obtaining the first playing instruction, namely, the mobile phone obtains a multimedia text which needs to be played synchronously with the second mobile phoneBefore the synchronous playing instruction of the piece such as a music file and a video file, a multimedia file such as a music file played by the mobile phone is acquired, when the video file is played, the mobile phone starts to play from a mobile phone system, and finally has delay time D through the processes of decoding the multimedia file, transmitting multimedia file data to bottom hardware and the like, and finally playing out a sound signal corresponding to the multimedia file through a mobile phone microphone or playing out an image signal corresponding to the multimedia file through a mobile phone display screen1And obtaining the playing delay time D of the second mobile phone caused by the hardware or/and software of the second mobile phone2And then determining the waiting time W for the mobile phone to wait for the second mobile phone to synchronously play the multimedia file according to a preset strategy.
Here, steps S201 to S203 executed before step S103 are specifically executed to perform step S101: the example is performed before obtaining a multimedia file. Specifically, when the mobile phone acquires the music file played by the mobile phone itself before the mobile phone obtains the music file downloaded by the mobile phone from the network and to be played synchronously with the second mobile phone, the mobile phone starts playing from the mobile phone system, and finally plays the sound signal corresponding to the music file through the mobile phone microphone with delay time D after the processes of decoding the multimedia file and transmitting the multimedia file data to the bottom hardware and the like caused by the hardware and/or software of the mobile phone itself1。
Then, the mobile phone will acquire the delay time D of the second mobile phone for playing the music file due to its own hardware or/and software2Of course, in practical application, the mobile phone may also first obtain the delay time D of playing the music file caused by the hardware or/and software of the second mobile phone itself2Then, the delay time D of playing the music file caused by the hardware or/and software of the mobile phone is obtained1The mobile phone can also simultaneously acquire the delay time D of playing the music file caused by the hardware or/and software of the mobile phone1And the delay time D of the second handset for playing the music file due to its own hardware or/and software2。
Referring to fig. 3, in practical applications, the mobile phone may further obtain the delay time D of playing the music file due to the hardware or/and software of the mobile phone itself in the following manner1That is, step S202 may be specifically realized by the following steps:
s301: obtaining a playing operation of playing the test signal at a first time;
s302: determining, based on the play operation, that the media player of the first electronic device plays out the test signal at a second time after the first time;
s303: acquiring a first time difference value between the first time and the second time as a delay time D of the first electronic device1。
In practical application, in order to obtain the delay time D of the mobile phone from the beginning of playing the mobile phone system, through the processes of decoding the multimedia file, transmitting the multimedia file data to the bottom layer hardware, and the like, and finally playing the sound signal corresponding to the music file through the mobile phone microphone, the single-frequency sound signal or the ultrasonic signal can be used as the delay time D for testing the sound signal played by the mobile phone1Specifically, when the ultrasonic wave is used as the test signal, the mobile phone can determine that the playing operation of playing the ultrasonic test signal is obtained at a first time, and then, the mobile phone can determine that the time from the beginning of the playing of the mobile phone system after the first time to the end of playing the sound of the ultrasonic test signal through the mobile phone microphone is a second time after the multimedia file is decoded and the multimedia file data is transmitted to the bottom layer hardware, so that the difference between the first time and the second time is the delay time D when the mobile phone plays the music file1。
Specifically, under the circumstance that the mobile phone and the second mobile phone are used as the audio of the home theater, when the mobile phone acquires the video file played by the mobile phone before the video file acquired by the mobile phone from the television equipment, the mobile phone starts playing from the mobile phone system due to the hardware or/and software of the mobile phone, and the multimedia file is decoded and transmittedThe process from the volume file data to the bottom hardware and the like, and finally the delay time D of the image signal corresponding to the video file is played through the display screen of the mobile phone1。
Then, the mobile phone will acquire the delay time D of the second mobile phone for playing the video file due to its own hardware or/and software2Similarly, the mobile phone may also obtain the delay time D of playing the video file caused by the hardware or/and software of the second mobile phone2Then, the delay time D of playing the video file caused by the hardware or/and software of the mobile phone is obtained1The mobile phone can also simultaneously acquire the delay time D of playing the video file caused by the hardware or/and software of the mobile phone1And the delay time D of the second handset in playing the video file due to its own hardware or/and software2。
Similarly, the mobile phone may also obtain the delay time D of playing the video file caused by the hardware or/and software of the mobile phone itself through the above specific implementation of step S2021If the mobile phone can obtain a playing operation of playing a video test file at the third time, and the fourth time after the third time determines that the video test file starts playing from the mobile phone system, the image information of the video test file is finally played through the mobile phone display screen after the processes of decoding the multimedia file, transmitting the multimedia file data to the bottom layer hardware and the like, then the difference value between the third time and the fourth time is the delay time D when the mobile phone plays the video file1. Similarly, the second mobile phone can be tested to have the delay time D in the manner described in step S301 to step S3032And will not be repeated here.
In the implementation, continuing with the above example, the delay time D of the second handset is obtained at the handset2And delay time D of mobile phone1Then, the mobile phone will execute step S203, and in practical applications, when the number of the second mobile phones is just one, step S203 can be implemented in a first manner as follows:
referring to fig. 4, it is a first implementation manner of step S203:
s401: comparing the delay times D1And the delay time D2The size of (d);
s402: when the delay time D1Is not less than the delay time D2If so, the waiting time W is zero;
s403: when the delay time D1Less than said delay time D2Then the waiting time W is the delay D1And the delay time D2The difference of (a).
In the implementation process, please continue to use the above example, specifically, the delay time D of playing the music file of the second mobile phone is obtained at the mobile phone2And the delay time D of the mobile phone playing the music file1Then, the mobile phone will compare the delay time D of playing music file by the mobile phone1And a delay time D of the second handset playing the music file2The size of the mobile phone, the delay time D when the mobile phone plays the music file1Equal to the delay time D of the second handset2When the mobile phone is started, the delay time required by the mobile phone to play the music file is equal to the delay time required by the second mobile phone to play the music file, at this time, the waiting time W for the second mobile phone to synchronously play the music file downloaded from the network by the mobile phone is zero, at this time, the mobile phone and the second mobile phone only need to execute a synchronous playing instruction at the same time (assuming that the current time of the mobile phone is equal to the current time of the second mobile phone), and the delay time D is set to be equal to the delay time W required by the second mobile phone to play the music file1Or a delay time D2Then, the sound signal corresponding to the music file downloaded from the network by the mobile phone is played synchronously with the second mobile phone.
Delay time D of mobile phone1Greater than the delay time D of the second handset2At this time, the waiting time W of the mobile phone is also zero, and if the mobile phone executes the synchronous playing instruction at the first time, the mobile phone will delay for a time D1Then playing the sound signal corresponding to the music file downloaded from the network by the mobile phone, and then the second mobile phone executes the synchronous playing instruction at the first moment and the delay time D is passed2And the size of the wait is D1And D2After the waiting time of the difference value, the sound signal corresponding to the music file is played, so that the purpose of playing the sound signal corresponding to the music file synchronously with the mobile phone can be realized.
Delay time D of mobile phone1Less than the delay time D of the second handset2Then the waiting time W of the mobile phone is D1And D2The difference between the two signals is the delay time D required for the mobile phone to execute the synchronous play command at the first time1And on the basis, the sound signal corresponding to the music file can be played after waiting for the W time, and the purpose of playing the sound signal corresponding to the music file synchronously with the second hand can be realized.
In practical applications, before the mobile phone performs step S103, the following steps may be further performed to make the current time of the mobile phone consistent with the current time of the second mobile phone:
a: acquiring standard time from a network, and acquiring first current time of the first electronic device and second current time of the second electronic device;
b: based on the standard time, calibrating the first current time and the second current time, obtaining a calibrated first current time and a calibrated second current time, so that the calibrated first current time is consistent with the calibrated second current time.
That is, the mobile phone obtains the standard time of the current time from the network, and obtains the first current time that the mobile phone of the current time has and the second current time that the second mobile phone has, and then the mobile phone calibrates the first current time of the mobile phone and the second current time of the second mobile phone according to the standard time of the current time obtained from the network, so as to make the current time of the mobile phone and the current time of the second mobile phone consistent.
Of course, in practical applications, before the mobile phone performs step S103, the following steps may be performed to make the current time of the mobile phone and the current time of the second mobile phone consistent:
c: acquiring the current time of second electronic equipment from the second electronic equipment;
d: calibrating the current time of the first electronic device based on the current time of the second electronic device, and obtaining the calibrated current time of the first electronic device so that the calibrated current time of the first electronic device is consistent with the current time of the second electronic device.
That is, the mobile phone first obtains the second mobile phone time at the current time, and then calibrates the time of the mobile phone at the current time according to the second mobile phone time at the current time, so that the purpose that the current time of the mobile phone is consistent with the current time of the second mobile phone can be achieved.
In practical applications, when the number of the second handsets is multiple, step S203 may be specifically implemented in the following second manner:
referring to fig. 5, a second implementation manner of step S203 is shown:
s404: obtaining a delay time D of each of the plurality of second electronic devices2；
S405: delay time D based on the first electronic device1And a delay time D of each of the plurality of second electronic devices2Determining the longest delay time;
