s1311, receiving a first disc control command.

The first disc control command is used for adjusting the volume of the multimedia file from the original volume to the second volume.

In this embodiment, the multimedia file volume may be understood as a global multimedia file volume. The global multimedia file volume is the volume of the multimedia file played by all the loudspeakers of the whole vehicle.

It should be noted that the second volume may be greater than the original volume or less than the original volume. For example, the original volume is 30, and the disc control command is received and then the second volume 10 and the second volume 45 can be adjusted. The second volume may be any reasonable volume value, and is not particularly limited herein.

S1312, judging whether the second volume is zero.

If the second volume is not zero, step S1313 is performed. If the second volume is zero, step S1317 is performed.

S1313, judging whether the background has the audio file to play.

If the background has no audio file to play, step S1314 is performed.

S1314, judging whether the media play record list is empty or not, or whether the last played multimedia file of the media play record list is a video file or not.

If the media play record list is empty and the last multimedia file played by the media play record list is a video file, step S1315 is performed.

S1315, judging whether the vehicle-mounted terminal has other media files to hold the audio file focus.

The audio file focus mechanism specifies that only one application can acquire the focus of sound at a time when the application emits sound from the horn.

If the vehicle-mounted terminal is not played by the speaker occupied by the focus of the other audio files, step S1316 is performed.

S1316, playing the last audio file in the media play record list.

If the second volume is zero, step S1317 is performed.

S1317, judging whether the background has the audio file to play.

If the background has audio files to play, step S1318 is performed.

S1318, suspending playing the audio file.

Further, on the basis of the above embodiment, referring to fig. 3, step S13 may be implemented as follows:

s1321, receiving a second disk control command.

The second disc control command is used for adjusting the volume of the multimedia file from the second volume to the original volume.

If the multimedia file type is a video file, step S1323 is performed.

S1323, resuming playing the video file.

If the multimedia file type is not a video file, it is understood that the multimedia file type is an audio file, step S1324 is performed.

S1324, judging whether the media volume of the audio file played in the background is zero.

If the media volume of the audio file is not zero, step S1325 is executed.

S1325, resuming playing the audio file.

Specifically, when the volume of the multimedia file of the audio file is not zero, the audio file is resumed.

If the volume of the multimedia file played in the background is zero, step S1326 is executed.

S1326, canceling to resume playing the audio file.

In one embodiment, an application scenario is: currently playing music using music software, when the global multimedia file volume is adjusted to be smaller than the threshold volume, the playing of the music file of the music software is paused, for example, the threshold volume may be set to 0 or other reasonable value, and no specific limitation is made here; when receiving a global multimedia file volume restoration instruction, judging whether the volume of the media file of music software is zero, and if not, restoring to play music; if it is zero, the music is not resumed. Another application scenario is: currently playing the video file by using the video file software, and suspending playing the video file of the video file software when the volume of the global multimedia file is adjusted to be smaller than the threshold volume; and when receiving the global multimedia file volume restoration instruction, restoring the video file of the playing video file software. It should be noted that, the restoration of playing the video file software does not need to determine whether the media volume of the video file software is zero, because: after the video file software resumes playing, the video file picture can be watched in the mute scene; however, if the volume of the multimedia file of the music software is zero, the passenger cannot hear even if the playback of the music is resumed, so that the playback of the music is not resumed when the volume of the media of the music software is zero.

In one embodiment, referring to fig. 4, when the state of the vehicle-mounted terminal is that the vehicle-mounted terminal cannot respond to the disc control command, step S13 (controlling playing of the multimedia file according to the state of the vehicle-mounted terminal and a preset policy) may be implemented as follows:

specifically, when any scene such as deleting a certain media application program, exiting a play page from a video file media, connecting an earphone to a secondary driving, ending the screen throwing to a central control screen by a secondary driving screen, and the like occurs, the volume of the multimedia file may not be adjusted according to a disk control command. In addition, when the last play record in the media play record list is a video file, the play cannot be started through the disc control after the vehicle wakes up due to dormancy. The vehicle dormancy refers to that when a vehicle dormancy key is pressed, the vehicle stops supplying power to a vehicle-mounted system such as multimedia and the like; sleep wakeup refers to that when a wakeup key is pressed, the vehicle resumes power supply to an in-vehicle system such as multimedia. It should be noted that the disc control command generally operates on the last media played in the media play record list.

S1331, acquiring an application program corresponding to the last playing record in the media playing record list.

S1332, judging whether the application program is a target application program.

The target application program is an application program deleted in the latest time period of the vehicle-mounted terminal.

S1333, if yes, judging the type of the multimedia file of the target application program.

Wherein the multimedia file types include: video files, audio files.

If the target application is a video file, step S1334 is performed.

S1334, acquiring a first application program so that the first application program plays according to a preset disc control command after preset time.

The first application program is an application program corresponding to a previous playing record of the last playing record; the preset disc control command includes: play, pause, last, next.

For example, the application a is deleted, and the application corresponding to the last play record is first obtained from the media play record list; assuming that there are 16 play records, if the application corresponding to the last play record 16 is application a, then it is determined whether application a is audio file software or video file software, if application a is video file software, then application B corresponding to the previous play record 15 of the last play record 16 is obtained, and after a preset time, for example, after receiving the previous instruction, application B may be used to play the play record 15.

If the target application is an audio file, step S1335 is performed.

S1335, acquiring a first application program, so that the first application program plays according to a preset disk control command after a preset time, and displaying playing information of the first application program on a desktop of the vehicle-mounted terminal in a media notification bar mode.

For example, if the application a is audio file software, the application B corresponding to the previous play record 15 of the last play record 16 is obtained, and after a preset time, for example, the last instruction is received, the application B may be used to play the play record 15. The difference from the video file software is that the audio file software can display the playing information of the application program B on any screen desktop in the form of a media notification bar when playing. The video file software can only be displayed on any screen in the form of a play interface, but cannot be displayed on any screen in the form of a media notification bar.

In addition, after step S1335 is performed, that is, after the play information of the first application is displayed on any one of the screen desktops in the form of a media notification bar, the following steps may be further performed:

Judging the screen attribution of the target program;

if the target program belongs to the central control screen, updating a media notification bar of the central control screen, and responding to a touch instruction of the central control screen.

The touch instruction is used for indicating that the target program is played according to the touch operation of the notification bar.

If the target program belongs to the secondary driving screen, updating a media notification bar of the secondary driving screen, and responding to a touch instruction of the secondary driving screen.

If the target program belongs to the rear-row screen, updating a media notification bar of the rear-row screen, and responding to a touch instruction of the rear-row screen.

In one embodiment, when the state of the vehicle-mounted terminal is that the vehicle-mounted terminal accesses the earphone, step S13 (controlling the playing of the multimedia file according to the state of the vehicle-mounted terminal and the preset policy) may be implemented as follows:

The first vehicle terminal is a vehicle terminal corresponding to the auxiliary driving screen; the second vehicle-mounted terminal is a vehicle-mounted terminal corresponding to the rear-row screen. The vehicle-mounted terminal mentioned in the embodiment of the method is a vehicle-mounted terminal corresponding to the central control screen. In addition, the central control screen is a display screen which is opposite to a vehicle driver; the auxiliary driving screen is an auxiliary screen opposite to the auxiliary driving of the vehicle; the rear screen is an entertainment screen which is opposite to the rear passengers.

For example, when the secondary driving screen is connected to the earphone, firstly judging the type of the multimedia file played by the nearest loudspeaker except the secondary driving screen; if the file is the audio file, a disk control instruction is given to the audio file displayed in the notification bar of the central control screen; if the video file is the video file, firstly judging whether the video file exits the playing page, if so, giving a disk control instruction to an audio file displayed in a notification column of a central control screen; if the playing page is not exited, a disk control instruction is given to the video file of the rear row of which the playing page is not exited.

In one embodiment, the multimedia file playing method further includes: and controlling the playing of the multimedia file according to the opening and closing state of the vehicle door and a preset strategy. Referring to fig. 5, the method is specifically implemented by the following steps:

S1341, when any door of the vehicle is in an open state, detecting whether other doors are in an open state.

When any door of the vehicle is in an open state and other doors of the vehicle are in a closed state, step S1342 is performed.

S1342, judging whether the original volume of the multimedia file is larger than the preset volume.

Wherein the original volume is used to represent the volume of the multimedia file before any door is opened.

Specifically, the preset volume can be set according to different usage scenarios or artificial preferences. For example, the preset volume may be 30 or other reasonable value. There is no particular limitation herein.

When the original volume of the multimedia file is greater than the preset volume, step S1343 is performed.

S1343, executing and recording the first operation.

The first operation is used for reducing the volume of the multimedia file from the original volume to a preset volume.

Further, when any door of the vehicle is opened, and the opened door is closed, step S1344 is performed.

S1344, detecting whether other doors are in an open state.

When it is detected that no other door is in the open state, step S1345 is performed.

S1345, detecting whether to execute the first operation.

When it is detected that the first operation has been performed, step S1346 is performed.

S1346, restoring the volume of the multimedia file from the preset volume to the original volume.

For example, before any door is opened when the vehicle stops driving, assuming that the volume of the multimedia file is 50 and the preset volume is 30, it may be first determined that the volume of the multimedia file is greater than the preset volume, and since the volume of the multimedia file 50 is greater than the preset volume 30, the volume of the multimedia file is automatically reduced to 30 when any door is opened, and the operation of reducing the volume of the multimedia file from the original volume to the preset volume after the door is opened is recorded. On the basis, when the opened car door is closed, detecting that if the operation of reducing the volume of the multimedia file to the preset volume exists before, the volume of the multimedia file is restored from 30 to 50; if the multimedia file volume has not been reduced from 50 to 30 before, no action is performed.

Through the steps of the method in the embodiment, the situation that when the vehicle door is opened, the volume of the multimedia file is too high, discomfort is caused to people outside the vehicle-mounted terminal can be avoided, and then the volume of the multimedia file of the vehicle-mounted terminal is intelligently adjusted through the multimedia file playing system.

Further, step S11 (controlling the playing of the multimedia file according to the opening and closing state of the vehicle door and the preset policy) may be further implemented as follows:

a. when any door of the vehicle is in an open state, if the original volume is detected to be adjusted to be the first volume, judging whether the first volume is adjusted by a medium central control volume adjusting button.

Wherein the first volume is greater than the preset volume.

b. And if the first volume is obtained by adjusting a media center control volume adjusting button, when the vehicle door is in a closed state, taking the first volume as the volume of the multimedia file.

Specifically, when any door of the vehicle is in an open state, if it is detected that the original volume is adjusted to a first volume greater than the preset volume, it is indicated that the vehicle-mounted terminal passenger considers that the volume of the multimedia file, which is obtained by reducing the original volume to the preset volume through the first operation, is lower at this time, so that the volume of the multimedia file is increased to the first volume which is considered to be suitable by the vehicle-mounted terminal passenger through the medium-control volume adjustment button.

For example, before the vehicle stops driving and opens any door, assuming that the multimedia file volume is 50, the multimedia file volume is reduced to the preset volume 30 by the first operation when any door is opened, and the vehicle-mounted terminal passenger considers that the multimedia file volume 30 is smaller, so the multimedia file volume is increased to the first volume 35 by the media center volume adjustment button. In this case, any door opened as described above is closed, and the multimedia file volume is not restored to 50 again in the manner of the above-described embodiment, but the first volume 35 is regarded as the multimedia file volume.

It should be understood that, although the steps in the flowcharts of fig. 1-5 are shown in order as indicated by the arrows, these steps are not necessarily performed in order as indicated by the arrows. The steps are not strictly limited to the order of execution unless explicitly recited herein, and the steps may be executed in other orders.
