For a person skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments. The embodiments in the present application shall all belong to the protection scope of the present application.
Some of the terms referred to in this application are briefly described as follows:
dial interface: the main interface is used for displaying time in the intelligent watch.
A crown: the crown is used for adjusting date, time and upper chain, is made of steel, titanium, ceramic or gold, and is divided into a common type or a screw-in type.
Common crown: the calibration time is directly pulled out. In the watch with the calendar, the first gear is used for adjusting the calendar, and the second gear is used for adjusting the time.
Screw-in type is also called spiral crown: the watch handle is locked in a spiral mode, and after the watch handle is rotated anticlockwise, the watch handle is unlocked and can be used normally. The spiral watch handle can effectively improve the waterproof function of the watch, and the watch handle is required to be locked after operation.
Dial plate: the watch is mainly used for displaying time and is related to the design of the watch. It can be designed into different shapes, and can use different materials, and the time scale can also be selected from simple lacquer print or protruding print. The content in the dial plate can be the content of fixed setting, also can change according to the demand, and the dial plate can include picture dial plate or video dial plate.
In wearable products in the market at present, the technical scheme of Huashi and apple is taken as an example for explanation. The product function of the Watch 3 is a video dial function; when the screen is lightened by lifting the hand, the video is automatically played. The Watch series of apple watches has a rainbow editing dial function in the product functions; the rotation of the 3D object in the interface can be controlled by the rotation of the crown. But the prior art has the disadvantage that the video cannot be randomly frozen during the playing process. Also, in another case, a 3D object is controlled.
In the embodiment of the application, the crown controls the interactive mode of the video frame by frame playing, so that a user can randomly position a certain frame of the video, a certain wonderful moment of the video is checked, and the interactive feeling between the user and the video is increased.
The following further describes the technical solution of the present application by way of an embodiment, as shown in fig. 1, a schematic diagram of an embodiment of a method for controlling video playing by a watch crown in the embodiment of the present application may include:
101. in response to a rotation operation of a crown, a direction and a rate of a current rotation of the crown are acquired.
Optionally, the method may further include: under the condition that the watch dial is set as the video dial, the watch is detected to be at a preset angle, or the operation of opening the watch by a response user is responded, the watch is lightened, and the video dial is played.
Optionally, the method may further include: and responding to the operation of playing videos by the user, and playing the videos, wherein the videos comprise videos stored in the local watch or videos sent by other electronic equipment. It will be appreciated that the video stored locally on the watch, or transmitted by other electronic devices, may also be used to set the video dial.
Optionally, the video format referred to in this application is not limiting. Such as Graphics Interchange Format (gif), sequential frame Format, are also included.
Illustratively, if the watch is worn on the hand of a user, the watch is provided with a video dial, and when the user lifts the hand, the watch is lightened to start to automatically play a video; when a user is using the video dial, the video can be automatically played after the user raises the hand and lights the screen. At this time, the user can instantly see the video content.
102. And determining the control information and the playing speed of the video according to the current rotating direction and speed of the crown.
The control information of the video comprises indication information of the video playing direction.
Optionally, the control information of the video further includes indication information of video volume adjustment and indication information of video brightness adjustment. Further, the method can also comprise indication information of the video rotation direction.
Optionally, the current rotation rate of the crown is in direct proportion to the video playing rate, the video volume adjustment rate, the video brightness adjustment rate and the video rotation rate; or, the rate at which the crown is currently rotated is inversely proportional to the rate at which the video is played, the video volume adjustment, the video brightness adjustment, and the video is rotated.
It will be appreciated that, in general, the faster the rate at which the crown is currently rotated, the faster the rate at which video is played; the slower the rate at which the crown is currently spinning, the slower the rate at which the video is played. But it is not excluded that in some cases, the faster the crown is currently rotating, the slower the video playing rate is; the slower the rate at which the crown is currently spinning, the faster the rate at which the video is played.
103. And playing the video according to the control information and the playing speed of the video.
(1) Optionally, the determining, by the watch, the control information and the play rate of the video according to the current direction and rate of rotation of the crown may include:
when the current rotation direction of the crown is clockwise, the watch determines that the video playing direction is indicating information of a forward direction, and when the current rotation direction of the crown is anticlockwise, the watch determines that the video playing direction is indicating information of a reverse direction; or,
when the current rotation direction of the crown is clockwise, the watch determines that the video playing direction is indication information of a reverse direction, and when the current rotation direction of the crown is anticlockwise, the watch determines that the video playing direction is indication information of a forward direction;
the watch determines the playing speed of the forward direction of the video or the playing speed of the reverse direction of the video according to the current rotating speed of the crown;
the playing, by the watch, the video according to the control information and the playing rate of the video may include:
the watch forwards plays the video according to the indication information of the forward direction and the playing speed of the forward direction of the video; or,
and the watch plays the video in a reverse mode according to the indication information of the reverse direction and the playing speed of the video in the reverse direction.
Illustratively, the user turns the watch crown and may control the video forward/backward. For example: when the watch is in a video dial interface and the watch rotates the crown clockwise, the video can be controlled to advance; fig. 2A is a schematic diagram illustrating control of video playing by a crown according to an embodiment of the present application. When the watch is in a video dial interface and the watch rotates the crown anticlockwise, the video can be controlled to back up; fig. 2B is another schematic diagram of controlling video playing through a crown in the embodiment of the present application.
Also for example: in some cases, when the watch is in a video dial interface, the user may control the video to rewind while rotating the crown clockwise; when the watch is in a video dial interface, and a user rotates the crown anticlockwise, the video can be controlled to advance.
Illustratively, the playback speed of the video may be changed when the watch crown is rotated at different speeds. For example: when the watch is in a video dial interface and a user rotates the crown rapidly, the video can be played in an accelerated way; fig. 2C is a schematic diagram illustrating the control of the video playing rate by the crown in the embodiment of the present application. When the watch is in the video dial interface, and a user rotates the crown at a slow speed, the video can be played at a slow speed. Fig. 2D is another schematic diagram illustrating the control of the video playing rate by the crown in the embodiment of the present application.
Also for example: in some cases, when the watch is in the video dial interface, the user rotates the crown quickly, and the video is played slowly; when the watch is in the video dial interface, the user rotates the crown at a slow speed, and the video can be played quickly.
Optionally, the playing, by the watch, the video according to the control information and the playing rate of the video may include: the watch frames the video to obtain a picture after the frame is extracted; and the watch plays the picture after the frame extraction according to the indication information and the playing speed of the video playing direction.
It should be noted that there are two main video playing modes of the conventional watch, as follows:
1) playing through Android native video playing (VideoView)
The method is not very convenient for supporting fast forward/fast backward of the video, can not accurately achieve the effect of fast forward/fast backward, can only fast forward or fast backward to the key frame, and can not achieve the effect of playing any one frame according to the rotation of the crown.
2) Playing through special customized player control
The scheme is universal on the mobile phone, and the customized playing control can support the effect of fast forward and fast backward, but when the scheme is applied to the mobile phone, the bag volume of the application is increased, and the performance of the watch is influenced.
In the embodiment of the application, in order to take performance and product effects into consideration, the watch video playing scheme is as follows: the video is selected to be subjected to frame extraction, and the picture is played after the frame extraction is finished, so that the effect same as that of video playing is achieved. For example, a multimedia extractor (MediaExtractor) or MediaCodec may be created to frame the video, and after the frame is completed, the picture for each frame may be saved to the watch. Fig. 3A is a schematic diagram illustrating a video decimating process performed by a multimedia extractor according to an embodiment of the present application.
The video playing process is divided into three parts as follows:
1. the mediaextrator, namely video parsing, mainly plays a role in audio and video separation, parsing header information and respectively acquiring audio and video streams.
2. MediaCodec, namely decoding the audio and video stream to obtain pcm and yuv data.
3. Render, i.e. Render the audio and video, respectively.
Optionally, the playing, by the watch, the video according to the control information and the playing rate of the video may include: and the watch plays the video frame by frame according to the indication information of the video playing direction and the playing speed.
Optionally, the playing, by the watch, the video frame by frame according to the indication information of the video playing direction and the playing speed may include: and the watch plays the frame-by-frame pictures according to the indication information and the playing speed of the video playing direction and the stored image index after frame extraction.
Illustratively, in the embodiment of the present application, a timed operation is simulated by the Handler, for example, every 1/24s, and the timed refresh display screen (View) displays pictures of corresponding frames. Namely, the watch can refresh a picture display screen (ImageView) to display pictures of corresponding frames every 1/24s according to the direction and the speed of video playing, so that the effect of video playing is achieved. Fig. 3B is a schematic diagram of displaying a picture by controlling a displayed picture index in the embodiment of the present application.
Optionally, the determining, by the watch, the control information and the rate of the video according to the current direction and rate of rotation of the crown may include:
the watch determines the playing speed of the video playing direction according to a first formula;
the first formula is CurrentFreq ═ (MaxFreq-MinFreq) × ate + MinFreq;
CurrentFreq is the refresh frequency of a current display frame, MaxFreq is the refresh frequency of a frame corresponding to the fastest rotation Rate of the crown, MinFreq is the refresh frequency of a frame corresponding to the slowest rotation Rate of the crown, Rate is the current rotation Rate of the crown, and the current rotation Rate range of the crown is (0, 1).
It can be understood that, in the embodiment of the present Application, the watch may monitor the rotation of the crown through an Application Programming Interface (API) provided by the system, and obtain the current rotation direction and the current rotation speed of the dial. Furthermore, whether the video advances or backs can be judged according to the current rotating direction of the dial plate, and the refreshing rate of the picture can be set according to the current rotating rate of the dial plate.
For example: clockwise crown rotation is video forward and counterclockwise crown rotation is video reverse. The speed of rotation is 1s refresh 100 frames of pictures at the fastest speed, 1s refresh 30 frames of pictures at the slowest speed, and the speed is converted into the number of pictures to be refreshed every second. The calculation formula is as follows:
CurrentFreq ═ (MaxFreq-MinFreq) × ate + MinFreq, wherein,
CurrentFreq is the refreshing frequency of the currently displayed picture;
MaxFreq is the refreshing frequency of the picture corresponding to the fastest rotation rate of the crown;
MinFreq is the refreshing frequency of the picture corresponding to the slowest rotation rate of the crown;
the Rate is the current rotation Rate of the crown and ranges from (0 to 1).
It should be noted that there are various mapping relationships between the crown rotation mode and the video control, and this application is intended to protect this interaction concept.
(2) Optionally, the control information of the video further includes indication information of video volume adjustment, and the determining, by the watch, the control information and the play rate of the video according to the current direction and rate of rotation of the crown may include:
when the current rotation direction of the crown is clockwise, the watch determines that the video volume is adjusted to be indicating information for adjusting the volume up, and when the current rotation direction of the crown is anticlockwise, the watch determines that the video volume is adjusted to be indicating information for adjusting the volume down; or,
when the current rotating direction of the crown is clockwise, the watch determines that the video volume is adjusted to be indicating information of turning down the volume, and when the current rotating direction of the crown is anticlockwise, the watch determines that the video volume is adjusted to be indicating information of turning up the volume;
the watch determines the rate of turning up the video volume or the rate of turning down the video volume according to the current rotation rate of the crown;
the playing, by the watch, the video according to the control information and the playing rate of the video may include:
the watch turns up the volume of the video according to the volume turning up indication information and the video volume turning up speed to play the video; or,
and the watch turns down the video volume to play the video according to the volume turning-down indication information and the video volume turning-down speed.
Illustratively, the user turns the watch crown to control the volume of the video to be turned up/down. For example: when the watch is positioned on a video dial interface and the watch rotates the crown clockwise, the volume of the video can be controlled to be increased; when the watch is positioned on a video dial interface and the watch rotates the crown anticlockwise, the volume of the video can be controlled to be reduced. Also for example: in some cases, when the watch is in the video dial interface and the user rotates the crown clockwise, the video volume can be controlled to turn down; when the watch is in a video dial interface and a user rotates the crown anticlockwise, the volume of the video can be controlled to be increased.
(3) Optionally, the control information of the video further includes indication information of video brightness adjustment, and the determining the control information and the play rate of the video according to the current direction and rate of rotation of the crown may include:
when the current rotation direction of the crown is clockwise, determining that the video brightness is adjusted to be indication information with larger brightness, and when the current rotation direction of the crown is anticlockwise, determining that the video brightness is adjusted to be indication information with smaller brightness; or,
when the current rotation direction of the crown is clockwise, determining that the video brightness is adjusted to be indication information with smaller brightness, and when the current rotation direction of the crown is anticlockwise, determining that the video brightness is adjusted to be indication information with larger brightness;
determining the rate of increasing the video brightness or the rate of decreasing the video brightness according to the current rotating rate of the crown;
the watch playing the video according to the control information and the playing rate of the video, which may include:
the watch increases the video brightness according to the indication information of the brightness increase and the speed of the video brightness increase to play the video; or,
and the watch turns down the video brightness to play the video according to the indication information of turning down the brightness and the rate of turning down the video brightness.
Illustratively, the user turns the watch crown to control the video brightness to be turned up/down. For example: when the watch is positioned at the interface of the video dial plate and the watch rotates the crown clockwise, the brightness of the video can be controlled to be increased; when the watch is positioned on a video dial interface and the watch rotates the crown anticlockwise, the video brightness can be controlled to be reduced. Also for example: in some cases, when the watch is in the video dial interface and the user rotates the crown clockwise, the video brightness can be controlled to be reduced; when the watch is in a video dial interface and a user rotates the crown anticlockwise, the video brightness can be controlled to be increased.
