Detailed Description
In order to make the technical solutions of the present invention better understood, those skilled in the art will now describe the present invention in further detail with reference to the accompanying drawings.
Fig. 1 is a block diagram of a video playback controller based on mobile device rotation detection according to an embodiment of the present invention.
The video playback controller based on the rotation detection of the mobile device in this embodiment includes a rotation detection module 10 and a video playback module 20. Wherein,
the video playing system comprises a rotation detection module 10, a video playing module and a video playing module, wherein the rotation detection module is used for collecting attitude data of the rotating mobile equipment in the process of playing a video file and sending the attitude data to the video playing module, and the attitude data comprises a rotating direction and an angle;
the rotation detection module is a sensor built in the mobile device, such as a gyroscope. The rotation method and the rotation angle of the mobile device are detected through the gyroscope. In specific implementation, the mobile device may optionally include a handheld mobile device with built-in gyroscope, acceleration sensor, magnetometer, and the like, such as a mobile phone and a pad.
And the video playing module 20 is configured to receive the gesture data and play the video file according to the gesture data, so as to control the playing progress, direction and speed of the video file.
The invention not only can play the video, but also can control the video playing process, namely, the control (forward or backward) of the video playing progress is achieved by rotating the mobile equipment. The traditional video player needs manual operation for controlling the video playing progress, for example, the control of the video playing is realized through a manual operation mode such as touch control of a progress bar or mouse click, the operation is not needed in the invention, a user only needs to rotate the handheld mobile equipment, the rotating direction of the mobile equipment and the rotating angle of the rotating direction can be detected through a sensor (such as a gyroscope and the like) arranged in the mobile equipment, the rotating direction and the rotating angle of the mobile equipment are detected in real time in the playing process of each video frame, if the rotating direction is consistent with the video playing direction, the video is played forwards (namely, the video is moved forwards) according to the rotating angle of the mobile equipment, and if the rotating direction is not consistent with the video playing direction, the video is played backwards (namely.
Further, the video playing module 20 comprises
The video reading unit 21 is configured to read and decode a video file, obtain a video image and a video frame number thereof, buffer the video image and the video frame number, and obtain a video frame image set through buffering.
The file information is the default information of each video file, which at least includes all parameters of the video file, such as Frame rate, Height, width, Bit rate, NumFrame, and the like.
Conventional video players play pictures sequentially from beginning to end, so that video encoding and decoding technologies are optimized correspondingly for playing continuous pictures sequentially, and video playing can be performed smoothly under the operation capability of the existing equipment. In order to solve the problem, the read and decoded video file is buffered to obtain the video image and the video frame number thereof, so as to control and realize the direct skip from the current video frame to the skip video frame.
The progress calculation unit 22 is used for calculating the corresponding relation between the video frames and the rotation angles according to the video frame numbers;
the invention aims to restore the user recording track to the maximum extent in the video recording process, namely, the user may move from one direction to another direction for recording in the video recording process. In a traditional video player, the video playing process of a user is static, and the user can know the recording direction of a recorder in the recording process only through the analysis of a video frame picture, so that the user lacks recording experience.
In order to meet the fluency of the video playing process, the read video file is decoded before playing, the decoded video frame image is buffered to obtain the video frame number of the whole video file, so that the rotating direction and the angle of the mobile equipment are selected according to the playing process of the video file, and the progress of video playing, namely the forward or backward progress, and the forward video frame number or the backward video frame number are controlled.
The playing progress unit 23 is configured to obtain a rotation direction and an angle of the mobile device according to the posture data, query the video frame image set, calculate a skip direction and a skip video frame of video playing according to the rotation direction and the angle, and control the current video frame to play the skip video frame along the skip direction.
The invention plays the video pictures continuously in sequence, jumps in the video in real time according to the operation of the user (namely the rotation of the mobile phone), and the jumping process is smooth and continuous (at least 30 frames of pictures need to be switched per second), so the user does not feel the incontinuity of the video pictures in the playing process, thereby ensuring the smoothness requirement of the video playing. In specific implementation, when the user selects a video file to play, as shown in fig. 2a, a video frame sequence diagram of the video file selected by the user is shown, and the video file represents a process from jumping from one side of the building in the figure to landing on the other side of the building in the figure. In specific implementation, the user can optionally rotate the mobile phone according to the direction (i.e. left and right directions) shown in fig. 2b, and also can rotate the mobile phone according to the direction (i.e. up and down directions) shown in fig. 2 c. When the user rotates the mobile phone, the mobile phone detects gesture data of the user rotating the mobile phone, and obtains a rotation direction and an angle of the mobile phone according to the gesture data, if the rotation direction of the user is detected to be a left-right direction as shown in fig. 2b, and a played video frame is obtained according to the angle calculation to be an X-th frame in a clockwise direction, when the mobile phone rotates in the left-right direction as shown in fig. 2b, a video frame before the rotation is still to a video frame as shown in a left image in fig. 2c, and a video file after the rotation jumps from the left image video frame of fig. 2c to a video frame as shown in a right image of fig. 2 c. It should be noted that the forward direction of video playing in this embodiment is the rotation direction shown in fig. 2b, so when it is detected that the user rotates in the reverse direction of the direction shown in fig. 2b, the video file is jumped to play (i.e. played in reverse direction) in the direction from the right to the left in fig. 2 c. Similarly, when the user rotates in the direction shown in fig. 2c, the mobile phone calculates the gesture data detected by the user's vertical rotation, and controls the playing of the video frame according to the calculation result.
Fig. 3 is a schematic structural diagram of another embodiment of a video playback controller based on mobile device rotation detection according to the present invention. The video playback controller based on the mobile device rotation detection in this embodiment includes a rotation detection module 10, a video playback module 20, and a video recording unit 30.
Wherein,
the video recording module 30 is configured to start a camera of the mobile device to record a video, acquire gesture data of the mobile device in a video recording process, and generate a video file and corresponding recording parameters thereof, where the recording parameters include a recording direction;
compared with the traditional video player, the method not only generates the recorded video file, but also comprises the attitude data of the recording process, in the embodiment, the default recording direction is a direction, and all the technical schemes that the attitude data of the recording process is collected in the recording process and the rotating shaft of the playing process is determined according to the attitude data are the protection scope of the method.
Further, the video recording module further comprises
The storage unit 31 is configured to store the recorded video file locally and/or upload the recorded video file to the cloud. In the embodiment, the user is set to backup through the keys (the example of the cloud is set in the embodiment, and other styles can be specifically set), and after the video recording is finished, the user only needs to click the storage key.
The video playing module 20 further comprises
And the playing parameter judging unit 24 is configured to acquire a video file, judge whether the video file includes the attitude data of the recording process, determine a rotating shaft according to the attitude data of the recording process if the video file includes the attitude data of the recording process, control the video to be played according to the rotating shaft and the attitude data, and control the video to be played according to a default rotating shaft direction if the video file does not include the attitude data of the recording process.
The video playing controller based on the mobile equipment rotation detection aims at enabling a user to control the playing of a video through rotating and moving a mobile phone, and for achieving the purpose, rotation and displacement data of the equipment need to be collected and calculated in real time. In practice, it is found that when a user moves a mobile phone, the user usually follows with the rotation operation, so that the invention is simplified into a data for collecting and calculating the gesture data. Meanwhile, it is found through observation and analysis of user behaviors that a user is usually used to move and rotate the mobile phone only in one direction of the left and right directions or the up and down directions, so that the video playback controller based on rotation detection of the mobile device described in this embodiment only collects and calculates the rotation angle of the mobile phone on one rotation axis of the x axis (left and right in the case of vertical screen or up and down in the case of horizontal screen) or the y axis (up and down in the case of vertical screen or left and right in the case of horizontal screen) during playback and/or shooting. As shown in fig. 4, the mobile device in this embodiment is described by taking a mobile phone as an example. The method comprises the following steps that original information collected by a built-in gyroscope in the mobile phone is rotation angular velocities of equipment on a rotation plane with three spatial coordinate axes of x, y and z as axes; the original information collected by the acceleration sensor is the acceleration components of the equipment on three spatial coordinate axes of x, y and z respectively; the raw information collected by the magnetometer is the magnetic force component of the equipment on three spatial coordinate axes of x, y and z. The 3 sensors acquire data of 3 coordinate axes, the data are called 9-axis data in a combined mode, and all attitude data such as the rotating angle, the displacement and the orientation of the equipment at any moment can be obtained through analysis and calculation of the 9-axis data.
In specific implementation, the video playing module of the present invention can play not only the video file recorded by the video recording module of the present invention, but also the video file played by other players, that is, the video file is not recorded by the video recording module of the present invention, so the rotation direction is default to the positive direction of the rotation in the terminal y-axis direction, the maximum rotation angle is dynamically set to Rmax according to the video frame number of the video file, and each frame of the video file is uniformly distributed in the interval of 0 to Rmax. If the video file is recorded by the video recording module, the rotation direction determines the positive rotation direction, namely the video playing direction, by the recording parameters.
Meanwhile, the invention can realize seamless intercommunication with the video file recorded by the existing video player, and increases video resources to facilitate system popularization. In addition, the method is convenient to interface with other platforms and technologies, provides a larger application scene for the technology, for example, the application is applied to the display and browsing of E-commerce products, and a user can realize 360-degree browsing of all geometric surfaces of the commodities by rotating the direction of a mobile phone. As shown in fig. 5a, with the schematic diagram of the continuous video frames in the video file of the e-commerce product-handbag displayed by 360 degrees played by the mobile phone, when the user holds the mobile phone and rotates the current video frame picture played in fig. 5b in the direction of the arrow, the picture played by the mobile phone jumps from the current video frame to fig. 5d, otherwise, the picture jumps to the video frame picture shown in fig. 5c in the reverse direction of the arrow, thereby realizing the purpose of controlling the video frame playing according to the direction of the user rotating the mobile phone. It should be noted that, in this embodiment, only the video playing controller based on the mobile device rotation detection according to the present invention is applied to the stereoscopic display and browsing of the e-commerce product, and the user realizes the preview of the handbag by rotating the mobile phone by 360 degrees; in specific implementation, the method can also be applied to other scenes, such as video files of products for realizing content display and browsing of all geometric surfaces of a target object by recording commodities, such as exhibition of museums, three-dimensional display and browsing of animal and human portraits, the category of the target object is not limited, all video files of the target object are decoded according to the method, video images of the target object and video frame numbers of the video images are obtained, and after gesture data of a user rotating a mobile phone (namely mobile equipment applying a video playing controller based on mobile equipment rotation detection disclosed by the invention) is detected, the technical scheme for controlling video frame playing according to the gesture data belongs to the protection scope of the invention.
Further, fig. 6 is a schematic structural diagram of another embodiment of a video playback controller based on mobile device rotation detection according to the present invention. The video playing controller based on the rotation detection of the mobile device in this embodiment includes a rotation detection module 10, a video playing module 20 and a video recording unit 30, wherein the video playing module 30 further includes
And an audio playing unit 25 for playing the background music selected by the user while the user views the video picture.
Whether the video file recorded by the video recording module is recorded by the existing video player or the video file recorded by the existing video player, the recording process of the video file is silent, so that the video is quite quiet during playing, the user is boring to watch the video file, and the user experience of the player is poor. It should be noted that the audio files in the audio library may be pre-stored locally or acquired online. The audio files pre-stored locally can be the audio files stored in the audio software in the mobile phone called through a preset interface, or the audio files pre-downloaded by the user through the audio library list.
Fig. 7 shows a video playing control method based on rotation detection of a mobile device according to the present invention, which includes the following steps:
s101, acquiring attitude data of the mobile equipment, wherein the attitude data comprises a rotating direction and an angle;
and S102, receiving the attitude data, and playing the video file according to the attitude data so as to control the playing progress, direction and speed of the video file.
Further, as shown in fig. 8, S102 specifically includes
S1021, reading and decoding the video file to obtain a video image and the video frame number thereof, caching, and buffering to obtain a video frame image set;
s1022, calculating the corresponding relation between the video frame and the rotation angle according to the length of the video file;
s1023, calculating the rotating direction and distance of the mobile equipment according to the attitude data, acquiring the position of the current video frame, inquiring the corresponding relation between the video frame and the rotating angle, judging the moving direction and the frame number of the video frame corresponding to the rotating direction and distance, and playing along the moving direction and the frame number of the video frame on the basis of the position of the current video frame.
Conventional video players play pictures sequentially from beginning to end, so that video encoding and decoding technologies are optimized correspondingly for playing continuous pictures sequentially, and video playing can be performed smoothly under the operation capability of the existing equipment. In order to reduce the amount of calculation of the mobile device in the process of playing the video file and improve the requirement of the player on the playing fluency, the invention plays the video pictures not sequentially and continuously, and jumps in the video in real time according to the operation of the user (namely the rotation of the mobile device). By using the conventional video playing technology, it is difficult to calculate the frame picture information of any random position in a short time. To achieve the requirement of smooth playing, at least 30 frames of pictures need to be switched every second, and if a conventional decoding technology is used, the corresponding video frames are decoded from the video in real time, which is far from achieving the requirement. Therefore, the invention firstly carries out preprocessing operation on the video file, namely, before the video is played, the video file is firstly decoded by using a conventional decoding mode, all pictures in the video are decoded and restored in advance and are cached in an image form. Therefore, in the playing process, the corresponding image data cached can be directly read, and the corresponding image is not decoded from the video. Meanwhile, aiming at the video file with longer time, the invention can reduce the decoding operation amount and avoid occupying too much running memory through a two-stage cache mechanism of memory and local file.
