That is, the multimedia data and the light description file may be obtained in different manners.
S102: and controlling the light source response device to flicker light in the playing process of the multimedia data based on the flicker parameter.
For example, the light source response means may comprise any one or more of: the electronic equipment comprises an internal flash lamp of the electronic equipment, a screen of the electronic equipment and an external flash equipment which is in wired connection or wireless connection with the electronic equipment.
A flash lamp is usually built in electronic equipment such as a mobile phone and a tablet personal computer, and in S102, the flash lamp can be controlled to flash according to flash parameters of a light flash event included in a light description file. In this case, the electronics can directly control the blinking of the light source response means.
Alternatively, the flash lamp may not be a flash lamp built in the electronic device, but may be an external flash device controlled by the electronic device, and the specific type of the external flash device is not limited. In this case, the electronic device may send a control command to the light source response device, and the light source response device controls itself to flash light based on the control command. For example, in some smart home scenes, the electronic device may control some lighting devices installed in the scene to flash light. For example, in a possible intelligent home scene, when a user watches an integrated art video through a mobile phone or an intelligent television, the current intelligent home products in a room, for example, an intelligent sound box (with a flash lamp) and intelligent light can flash in coordination with the music rhythm of the integrated art video, so that light of a lighting device in the current environment can be utilized to create a better playing atmosphere, the watching experience of immersion is provided for the user, and the playing effect is improved.
Or, in S102, the screen of the electronic device may also be controlled to flash according to the flash parameter of the light flash event included in the light description file. The electronic equipment can also generate the flickering effect when the screen is turned on or off.
In one embodiment, S102 may include: determining a light flicker event corresponding to a current frame played in the multimedia data as a target light flicker event in the playing process of the multimedia data; and controlling a light source response device to flicker light according to the flicker parameters of the target light flicker event.
As described above, the flashing parameters of the light flashing event may include the flashing pattern of the light flashing event. The blinking pattern includes any one or more of: flashing frequency, flashing brightness, flashing color and preset flashing grade.
In particular, the flashing pattern may include a flashing frequency, and the flash may be controlled to flash at the flashing frequency of the light flashing event. For example, the light source response device may be a built-in flash lamp of the electronic device, and the flash lamp is controlled to flash at a certain flashing frequency, which may be understood as that the electronic device controls the flash lamp to turn on and off according to the frequency, so as to achieve the flashing effect. For example, if the flashing frequency is 3 times per second, the electronic device controls the flash lamp to be turned on, turned off, turned on, and turned off within one second, so that the effect of flashing 3 times per second is achieved. In the embodiment of the present invention, the interface for controlling the flash lamp by the electronic device and the control mode of the bottom layer are not limited.
The brightness of the light source response device is adjustable, and the flashing mode can comprise flashing brightness. For example, the light source response means comprises a screen of the electronic device, the brightness of the screen being adjustable. In this case, in S102, the screen of the electronic device may be controlled to blink according to the blinking brightness of the light blinking event.
The flashing pattern may comprise a flashing color, and the light color of the light source response device may be controllable, for example, multiple flashing lights of different colors may be configured in the electronic device, in which case, the multiple flashing lights may be controlled to flash in accordance with the flashing pattern of the light flashing event to form various lights of different colors. Or, the screen of the electronic device may emit light of a plurality of colors, and in this case, the screen of the electronic device may be controlled to flash in a flashing manner of the light flashing event to form various light of different colors.
As described above, the flicker parameter may include a preset flicker level, and the preset flicker level is divided based on the flicker mode of the light flicker event. For example, in one case, the flashing manner of the light flashing event may be a flashing frequency, and in this case, the preset flashing level may be a rhythm level divided based on the flashing frequency of the flashing event. For example, 0-5 flashes per second may be classified as a tempo class of 1, 6-10 flashes per second may be classified as a tempo class of 2, 11-15 flashes per second may be classified as a tempo class of 3, and so on. In this example, the higher the flicker frequency, the larger the rhythm level, or in other cases, the higher the flicker frequency, the smaller the rhythm level, and the specific division is not limited.
Alternatively, the brightness of the light source response unit may be adjustable, and the flashing pattern of the light flashing event may include a flashing brightness, in which case the flashing level may be divided based on the flashing brightness.
Or, in another case, the flashing manner of the light flashing event includes flashing frequency, brightness, color, and the like, in this case, a plurality of flashing levels may be preset, and the flashing manner in different flashing levels is different, for example, the flashing manner in the flashing level 1 includes: the flicker frequency is 5 flickers per second, and the flicker brightness is 120cd/m 2 The blinking color includes red, and the blinking manner in the blinking level 2 includes: the flicker frequency is 10 flickers per second and the flicker brightness is 140cd/m 2 The blinking colors include red and yellow, and the blinking manner in the blinking level 3 includes: the flicker frequency is 20 flickers per second, and the flicker brightness is 160cd/m 2 The blinking colors include red and blue, etc., and the specific manner of blinking included in the blinking levels is not limited.
In one embodiment, if a current frame played in the multimedia data is in a flashing time period of any one of the light flashing events corresponding to the multimedia data, the light flashing event is determined as a target light flashing event.
In another embodiment, if a current frame played in the multimedia data is not in a flashing time period of any one of the light flashing events corresponding to the multimedia data, a flashing event which is located after the current frame and has the smallest time interval with the current frame is searched in the light description file and is used as a candidate light flashing event; and when the starting time of the candidate light flicker event is reached, determining the candidate light flicker event as a target light flicker event.
For example, if the user does not perform fast forward, fast backward, or other operations for adjusting the playing progress during the playing of the multimedia data, or if the multimedia data is completely played according to its own progress, the light flicker events may be sequentially executed according to the time sequence of the light flicker events in the light description file.
In this embodiment, searching for the candidate light flicker event may include: and searching a flash event with a starting time later than the current playing time of the multimedia data and a minimum interval between the starting time and the current playing time in the light description file as a candidate light flash event. And when the starting time of the candidate light flicker event is reached, determining the candidate light flicker event as a target light flicker event, and returning to execute the step of searching the light description file for the flicker event with the starting time being later than the current playing time of the multimedia data and the minimum interval between the starting time and the current playing time as the candidate light flicker event.
In this embodiment, after the candidate light flicker event is found, a first timer may be generated and enlightened, and the timing duration of the first timer is the duration between the current playing time of the multimedia data and the starting time of the candidate light flicker event; and after the first timer finishes timing, determining the candidate light flicker event as a target light flicker event, and returning to continuously search the candidate light flicker event.
For example, assume that the current playing time of the multimedia data is T 0 Traversing each light flicker event in the light description file, assuming that the light flicker event comprises n light flicker events, and the starting time of the n light flicker events is T 1 ～T n . Lookup T 1 ～T n Is greater than T 0 And is and T 0 Is the smallest, assuming that the search result is T x ，T x The lamp flashing event is the event x.
Creating a Timer1, wherein the duration of the Timer1 is T x -T 0 When the Timer1 finishes timing, the event x is started to be executed. Executing a light flashing event, namely executing S102, and controlling the light source response device to flash in a flashing mode of the event in a flashing period of the event.
Then returning to execute the searching step: the current playing time of the updated multimedia data is still marked as T 0 Look up T 1 ～T n Is greater than T 0 And is and T 0 Is the smallest one. The subsequent procedures are similar and are not described again.
In one embodiment, the flicker parameter includes a flicker period, and the flicker period includes a start time; if an instruction for adjusting the playing progress is received in the process of playing the multimedia data, re-determining a current frame played in the multimedia data based on the instruction for adjusting the playing progress; judging whether the redetermined current frame is in the flickering time interval of the light flickering event; if so, determining the lamplight flicker event corresponding to the flicker time interval in which the current frame is positioned as the target lamplight flicker event; if not, determining a light flicker event corresponding to the next flicker time interval corresponding to the re-determined current frame as a light flicker event to be executed; and when the starting time of the light flicker event to be executed is reached, determining the light flicker event to be executed as a target light flicker event.
As described above, if the user does not perform fast forward, fast backward, or other operations of adjusting the playing progress during the playing of the multimedia data, the target light flashing events may be determined in sequence according to the time sequence of the light flashing events in the light description file.
In this embodiment, if the user performs fast forward, fast backward, or other operations for adjusting the playing progress, the electronic device receives the instruction for adjusting the playing progress, and the electronic device re-determines the current frame played in the multimedia data based on the instruction for adjusting the playing progress. And on one hand, the electronic equipment starts playing the multimedia data from the redetermined current frame, on the other hand, the light flicker event corresponding to the current frame is redetermined as the target light flicker event, and then the subsequent process is continued.
If the electronic equipment receives the instruction of adjusting the playing progress and the light source response device is flickering, the light source response device can be controlled to stop the light flickering and then the target light flickering event is determined again. When the target light flicker event is determined again, if the current frame is in the flicker time interval of a certain light flicker event, the light flicker event can be directly determined as the target light flicker event, and the target light flicker event is executed; and if the current frame is not in the flashing time interval of a certain light flashing event, waiting for executing the next light flashing event.
As described above, the light description file is consistent with the timing start point in the multimedia data, and therefore, after the current frame played in the multimedia data is determined again, the position in the light description file corresponding to the current frame can be determined, and the light flicker event at the position is the target light flicker event. And determining whether a light flicker event needing to be executed exists at the position, corresponding to the current frame, in the light description file, if so, executing the light flicker event, otherwise, waiting until the next light flicker event needing to be executed is executed, and executing the light flicker event.
In one embodiment, the flicker parameter of the target light flicker event satisfies a flicker parameter condition set by a user.
In one case, a light flicker event with flicker parameters meeting preset flicker parameter conditions may be determined in the light description file as an effective light flicker event; and determining an effective light flicker event corresponding to the current frame played in the multimedia data as a target light flicker event.
Alternatively, the first and second electrodes may be,
in another case, a light flicker event corresponding to a current frame played in the multimedia data may also be determined; if the flicker parameter of the determined light flicker event meets the flicker parameter condition set by the user, taking the determined flicker parameter as a target light flicker event; and if the determined flicker parameter of the light flicker event meets the flicker parameter condition set by the user, not taking the light flicker event as the target light flicker event, namely not executing the light flicker event.
In this case, the user may set the blinking parameter condition in advance, or the blinking parameter condition may be a default value, and the setting of the specific blinking parameter condition is not limited. Assuming that the preset flicker level includes 1-Z, Z representing a positive integer greater than 1, the flicker parameter condition may be that the flicker level is greater than Y, Y representing a positive integer less than Z.
Besides the foregoing manner, the user can also adjust the flicker parameter condition during the process of playing the multimedia data.

Or, if the user feels that the flicker frequency of the currently executed light flicker event is too fast, the user may reduce the flicker frequency of the light flicker event by adjusting the flicker parameter condition. The adjustment modes for the user to specifically adjust the flicker parameter condition are not listed one by one.
In some cases, the blinking patterns may be selected by a user, with each blinking pattern corresponding to a blinking parameter. Continuing the above example, assume that the flicker parameter includes flicker frequency, the flicker level is rhythm level, 0-5 times of flicker per second is divided into rhythm level 1, 6-10 times of flicker per second is divided into rhythm level 2, and 11-15 times of flicker per second is divided into rhythm level 3; if the flicker mode selected by the user is a soft mode, the corresponding flicker parameter condition may be that the rhythm level is not greater than 2, and if the flicker mode selected by the user is a hard-burst mode, the corresponding flicker parameter condition may be that the rhythm level is not less than 3, and the like, and the specific flicker mode is not limited.
For another example, in the above case, a plurality of flashing levels are preset, and the flashing modes in different flashing levels are different, in which case, each flashing mode may correspond to one flashing level. Alternatively, user selection of a blinking pattern may be understood as selection of a qualified blinking level.

After the Timer1 finishes timing, the searching steps can be returned to be executed: updating the current playing time of the multimedia data, still recording as T 0 Searching for a light flicker event having a start time greater than T from among the available light flicker events 0 And its start time with T 0 The interval of (c) is minimal. The subsequent procedures are similar and are not described again. Or, if the user adjusts the flashing parameter condition in the process of playing the multimedia data, the searching step is returned to be executed after the flashing parameter condition is determined again.
When the Timer1 finishes timing, the event x is started to be executed. And when the event x is executed, the Timer2 can be created again, the duration of the Timer2 is the flashing duration of the event x, and when the Timer2 finishes timing, the flash lamp is controlled to stop flashing.
