All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terms first, second and the like in the description and in the claims of the present invention are used for distinguishing between different objects and not for describing a particular order. Furthermore, the terms "comprises" and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or modules is not limited to the listed steps or modules but may alternatively include other steps or modules not listed or inherent to such process, method, article, or apparatus.

Wherein, it is assumed that the number of image frames obtained in a unit time such as 1 second during shooting is M (i.e. the frame rate is Mfps), and the image frames are played according to N (i.e. the frame rate is Nfps) per unit time during playing, and if M is greater than N, the slow mode is obtained, a slow motion effect is obtained; if M is less than N, the mode is the fast mode, then a fast action effect can be obtained; if M is equal to N, it is the normal mode, then a normal playing effect can be obtained. Wherein M and N are both greater than 0. For example, if the shooting device shoots at a high frame rate (e.g., 120p), a video of 30p is output, i.e., 4x slow motion shooting, and if 1 photo is taken in 1s, a video of 30p is output in 1 second in 30s, i.e., 30x time-lapse shooting.
The embodiment of the invention discloses a video recording method, a video recording device and shooting equipment, which can record a video according to the recording rate required by a user, thereby improving the recording efficiency and flexibility of the video. The details are described below.
Referring to fig. 1, fig. 1 is a schematic flowchart of a video recording method according to an embodiment of the present invention. Specifically, as shown in fig. 1, the video recording method according to the embodiment of the present invention may include the following steps:
101. and acquiring the playing speed of the shooting equipment when playing the video image.
102. And acquiring the recording rate parameter determined based on the user selection instruction.
Specifically, when a video is recorded, the recording rate parameter of the video recording can be determined according to the user requirement. For example, a plurality of speed keys (for example, the speed keys are arranged on the shooting device itself or a pan/tilt head connected to the shooting device) may be provided for the user to select the recording speed parameter, or an interactive interface including a plurality of recording speeds is output for the user to select the recording speed parameter, or a window is output for the user to directly input the recording speed parameter, and so on. Wherein, the recording rate parameter can be a specific rate value, such as 15fps, 30fps, 60fps, 120fps, etc.; alternatively, the recording rate parameter may be a rate change value indicating a slowing down or speeding up of the recording rate, such as speeding up by 3 times (+3x), slowing down by 4 times (-4x), and so on.
103. And recording the video image based on the playing rate and the recording rate parameter.
Specifically, after determining the playing rate when playing the video and the required recording rate parameter, the video image may be recorded based on the playing rate and the recording rate parameter, for example, a writing rate may be calculated based on the playing rate and the recording rate parameter, so as to write the video data based on the writing rate, thereby completing the video recording. The playing rate can be matched with the shooting rate of the shooting equipment, so that the video can be shot and recorded at the same time, the video can be recorded after the shooting is finished, and the flexibility and the efficiency of video recording are high.
In the embodiment of the invention, the video image can be recorded based on the playing rate and the recording rate parameter by acquiring the playing rate of the shooting equipment when the video image is played and the recording rate parameter determined based on the user selection instruction, so that the video can be recorded according to the recording rate required by the user, and the recording efficiency and the flexibility of the video are improved.
Further, referring to fig. 2, fig. 2 is a schematic flowchart of another video recording method according to an embodiment of the present invention. Specifically, as shown in fig. 2, the video recording method according to the embodiment of the present invention may include the following steps:
201. and acquiring the playing speed of the shooting equipment when playing the video image.
202. And acquiring the recording rate parameter determined based on the user selection instruction.
Optionally, the obtaining of the recording rate parameter determined based on the user selection instruction may specifically be: acquiring equipment parameter information of the shooting equipment; determining at least one group of recording rate parameters supported by the shooting equipment based on the equipment parameter information; displaying an interactive interface including the at least one set of recording rate parameters; and receiving a selection instruction input by a user aiming at the at least one group of recording rate parameters, wherein the selection instruction can indicate that the determined recording rate parameters exist. So that the recording rate parameter required by the user can be determined based on the selection instruction.
Specifically, since frame rate ranges supported by different shooting devices may be different, the frame rate that can be supported by the shooting device may be determined by obtaining device parameter information of the shooting device, such as a device model, to determine that the slowest speed or the fastest speed of recording is a multiple of a normal speed, so that video recording can be performed based on the frame rate supported by the shooting device. Optionally, after the frame rate that can be supported by the shooting device is determined, the recording rate corresponding to the supported frame rate may be output for the user to select, so that the user selects one rate from the recording rates to record the video. In other alternative embodiments, the user may also input the recording rate parameter by clicking a preset button, for example, by clicking a rate button disposed on the shooting device or a cradle head connected to the shooting device.
203. And calculating the writing rate of the video data corresponding to the video image based on the playing rate and the recording rate parameter.
204. And recording the video image according to the writing rate.
Optionally, the calculating a writing rate of video data corresponding to the video image based on the playing rate and the recording rate parameter may specifically be: when the recording mode indicated by the recording rate parameter is determined to be a fast mode, determining a first ratio of the recording rate parameter to the playing rate; and calculating a writing rate based on the playing rate, the fast mode and the first ratio, and taking the calculated writing rate as the writing rate of the video data corresponding to the video image. Specifically, when it is detected that the recording rate parameter selected by the user corresponds to the fast mode, a multiple of the recording rate parameter and the playing rate, that is, a first ratio, may be obtained, and the fast action processing may be performed on the recorded video based on the first ratio, and the video may be written into a file for storage. For example, assuming that the obtained playback rate is 30fps, and it is detected that the user clicks the rate button "+ 3 x" set by the user, it is determined that the recording mode corresponding to "+ 3 x" is the fast mode, the first ratio is 3, and the writing rate is 120fps by calculation, and then the video data can be written at the writing rate that the playback rate is increased by 3 times according to the recording rate parameter.
Optionally, the calculating a writing rate of video data corresponding to the video image based on the playing rate and the recording rate parameter may specifically be: when the recording mode indicated by the recording rate parameter is determined to be a slow mode, determining a second ratio of the playing rate to the recording rate parameter; and calculating a writing rate based on the playing rate, the slow mode and the second ratio, and taking the calculated writing rate as the writing rate of the video data corresponding to the video image. Specifically, the slow speed range may be further determined by obtaining a frame rate range supported by the shooting device and a normal play rate, and determining that the supported maximum frame rate is a multiple of the play rate. When detecting that the recording rate selected by the user corresponds to the slow mode, acquiring a multiple of the playing rate and the recording rate parameter, namely a second ratio, and performing slow motion processing on the recorded video based on the second ratio and writing the video into a file for storage. For example, assuming that the obtained playback rate is 60fps, and detecting that the user clicks the set rate key "-2 x", it may be determined that the recording mode corresponding to "-2 x" is the slow mode, the second ratio is 2, and the writing rate is calculated to be 30fps, and then the video data may be written at the writing rate which is 2 times slower than the playback rate according to the recording rate parameter.
Alternatively, the recording parameter may be a specific rate value, and a rate value indicated by a recording rate parameter that can be input by a user operating the shooting device may be used as the writing rate.
205. A rate change instruction based on a user operation input is received.
206. And responding to the speed changing instruction, suspending the recording of the video image, and acquiring a new recording speed parameter corresponding to the speed changing instruction.
207. And recording the video image based on the playing rate and the new recording rate parameter.
In the recording process, whether a speed changing instruction for indicating changing of the recording speed is received or not can be detected, so that the recording speed can be changed when the user changing instruction is confirmed to be received, and the recording speed can be flexibly adjusted. Wherein, the speed changing instruction carries the changed recording speed information, namely the new recording speed parameter. For example, a rate key indicating a recording rate may be added to the shooting device in advance, for example, a rate key for acceleration/deceleration (+/-) may be added to a handheld holder of the shooting device, and by clicking the rate key, the operation mode of the sensor may be switched to 120p, 30p, 1p or more. The user can change the video recording rate of formulation through operating the button on the handheld cloud platform of shooting equipment to realize the combination of intelligent speed governing, fast and slow speed in the video recording process.
Further optionally, in some embodiments, the recording of the video image may also be stopped when the recording rate parameter input is detected or the shooting device stops playing the video image. Further, when the new writing rate is obtained, recording can be continued according to the new writing rate.
Further optionally, in some embodiments, object tracking may also be performed based on the video images. The thread used by the object tracking (tracking), the thread used by the video image playing and the thread used by the video image recording can be independent. The tracking refers to selecting a specific target (such as a person, an animal and the like) in an image, when the target moves, a video recording device can move along with the target so that the target is always in an image or a video shot by the video recording device, and the tracking can be used for the same image as the recorded video image or different images. tracking can acquire an original image for shooting by using the image so as to ensure the tracking efficiency; the recorded video image may be an original image or a processed image.
Specifically, as shown in fig. 3, in the embodiment of the present invention, an independent thread of the video stream is responsible for processing the video stream data, and the video stream can be copied into multiple copies of data. One of the two sets of video recording threads can be used for performing frame rate adjustment through a Central Processing Unit (CPU) and delivering the frame rate adjustment to the video recording thread for video recording; one part can be delivered to a video display thread to be displayed by an image processor (GPU for short); one copy may be given to the racking thread for processing by the GPU. Therefore, simultaneous video display, video recording and tracking can be realized through multi-channel resource scheduling under multithreading, and the rapid and flexible switching of the recording rate and the rapid synthesis of the video are ensured through the reasonable resource allocation processing of the CPU or the GPU.
For example, when recording a stored video image or a video image currently being shot based on a user requirement, the user may select a recording rate and click to start recording, thereby triggering video recording according to the selected recording rate parameter and a playing rate corresponding to the recorded video image. Specifically, a file can be newly created in an appointed directory of a local folder, a write-in thread is newly created for thread round robin, and when a video to be recorded is in a non-suspended state, video data of the recorded video can be written in according to whether a target recording speed set by a user is a slow mode or a fast mode, and the data can be written in the file by modifying the time of video callback data. Further, in the video recording process, if the user needs to modify the recording rate, when a rate modification instruction input by the user is received, for example, the user clicks a rate recording instruction triggered by another recording rate, the recording may be suspended first, and the latest recording rate set by the user, that is, a new recording rate parameter, is obtained. And detecting that the new recording rate parameter is a slow mode or a fast mode, and setting a video call-back frame rate based on the new recording rate parameter, namely determining a new writing rate. Further, the suspend mode may be turned off to ensure that the write thread continues to write data. When the user clicks to stop recording or the video playing is completed, the writing is completed, and the thread can be closed. At this point the recording is complete.
In the embodiment of the invention, the synchronous recording and other operations can be ensured through the control of an independent write-in thread and the change of the write-in video data rate, thereby preferably realizing multi-path operation, for example, video display and speed-regulating video recording can be carried out at the same time, and tracking is supported at the same time, so that the video with alternate speeds and speeds can be obtained at one time, and the waiting time for generating the video is reduced. Meanwhile, through reasonable resource allocation of the GPU and the CPU, multi-channel data operation can still be carried out smoothly at the same time, writing can be carried out through the time of modifying the recalled video data, namely the writing speed of the recorded video is modified, so that the frame loss phenomenon is prevented, and the efficiency, the flexibility and the reliability of video recording are effectively improved.
