The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
The embodiment of the present disclosure provides a screen recording method, as shown in fig. 1, which is applied to a cloud server, a virtual machine and a receiving end module are located on the cloud server, the virtual machine is connected with a cloud terminal device via the receiving end module, and the method includes the following steps:
For example, as shown in fig. 2, the system is a schematic structural diagram of an image transmission system, where the system includes a cloud server and at least one cloud terminal device, at least one virtual machine runs on the cloud server, the cloud server allocates one virtual machine to each cloud terminal device, and the cloud terminal device obtains a corresponding application service by connecting to the corresponding virtual machine. Specifically, after the cloud terminal device obtains a desktop image of a corresponding virtual machine, a user generates a reverse control instruction by operating the desktop image, the cloud terminal device sends the reverse control instruction to the corresponding virtual machine, the virtual machine executes corresponding processing according to the reverse control instruction, and finally sends an image corresponding to a processing result to the cloud terminal device.
For example, a plurality of virtual keys may be arranged in a desktop image displayed on the cloud terminal device, and if a user needs to record a screen, the screen recording key is clicked, so that the cloud terminal device generates a screen recording request after acquiring an instruction corresponding to the screen recording key, and sends the screen recording request to a virtual machine connected with the cloud terminal device; or, the user performs corresponding gesture input through a touch screen of the cloud terminal device, for example, a single finger slides up, a three finger slides down, and the like, to initiate a screen recording request; or the cloud terminal equipment is provided with a camera or a voice recognition module, if the user needs to record the screen, the user can put a preset screen recording gesture or speak a word about the screen recording, so that when the cloud terminal equipment acquires the screen recording gesture or the word about the screen recording and determines the voice to be the screen recording, a screen recording request is generated, and the screen recording request is sent to a virtual machine connected with the cloud terminal equipment.
It should be noted that the cloud terminal device may be a cloud mobile phone, a cloud computer, or may also be an intelligent terminal device equipped with a receiving end module (R end module), such as a mobile phone, a tablet computer, a PC, and the like, which is not limited in this disclosure.
And 102, the virtual machine obtains a screen recording file based on the current playing content acquired by the receiving end equipment.
Specifically, the method for obtaining the screen recording file by the virtual machine based on the current playing content acquired by the receiving end device includes the following two methods:
the first method comprises the following steps: sending a first screen recording instruction to a receiving end module, wherein the first screen recording instruction is used for indicating to acquire a current frame image and/or current audio content in current playing content, so that the receiving end module sends the acquired current frame image and/or current audio content to the virtual machine; the virtual machine encodes the current frame image and/or the current audio content according to a target encoding algorithm to obtain the screen recording file; the target coding algorithm is a preset coding algorithm adopted during screen recording.
Illustratively, the virtual machine enters a screen recording mode when receiving a screen recording request sent by the cloud terminal device, sends a first screen recording instruction for instructing to acquire a current frame image and/or current audio content in currently played content to a receiving end module connected with the virtual machine, the receiving end module acquires the current frame image and/or current audio content currently acquired when receiving the first screen recording instruction, continuously sending the current frame image and/or the current audio content collected at present to the virtual machine, continuously receiving the current frame image and/or the current audio content by the virtual machine, when the current frame image and the current audio content are included, aligning the current frame image and the current audio content in terms of time, and then coding the aligned current frame image and the aligned current audio content according to a target coding algorithm to obtain a corresponding screen recording file; and when only the current frame image or the current audio content is included, directly coding according to a target coding algorithm to obtain a screen recording file. It can be known that the first method is to record a screen by means of the desktop image capturing function and the audio capturing function of the receiving end module.
It should be noted that the target encoding algorithm is an encoding algorithm required by a preset screen recording, for example, the target encoding algorithm may be MP4(Moving Picture Experts Group 4), FLV (Flash Video, streaming media format), AVI (Audio Video Interleaved format), and the like.
It should be noted that, when the virtual machine only encodes the current frame image according to the target encoding algorithm, the obtained screen recording file only includes the image without sound; when the virtual machine simultaneously encodes the current frame image and the current audio content according to a target encoding algorithm, the obtained screen recording file comprises both images and sounds; when the virtual machine only codes the current audio content according to the target coding algorithm, the obtained screen recording file only comprises sound and no image.
It should be noted that the receiving end module may also continuously collect desktop images and/or audio contents of the virtual machine, encode the collected desktop images and/or audio contents, and send a code stream obtained by encoding to the cloud terminal device connected to the receiving end module, thereby implementing real-time display of a video on the cloud terminal device. That is to say, after the receiving end module collects the current frame image and/or the current audio content, on one hand, the current frame image and/or the current audio content are/is returned to the virtual machine according to the first screen recording instruction received from the virtual machine; on the other hand, normal acquisition and encoding of desktop images and/or audio contents are still carried out, and code streams obtained through encoding are sent to cloud terminal equipment connected with the receiving end module.
The second method comprises the following steps: sending a second screen recording instruction to a receiving end module, wherein the second screen recording instruction is used for instructing to acquire the screen recording file, so that the receiving end module encodes the acquired current frame image and/or current audio content according to a target encoding algorithm to obtain the screen recording file, and sends the screen recording file to the virtual machine; and the virtual machine receives the screen recording file.
Illustratively, when receiving a screen recording request sent by cloud terminal equipment, a virtual machine sends a second screen recording instruction for instructing to acquire a screen recording file to a receiving end module connected with the virtual machine, and when receiving the second screen recording instruction, the receiving end module acquires a current frame image and/or current audio content acquired currently, encodes the current frame image and/or the current audio content according to a target encoding algorithm to obtain a corresponding screen recording file, and finally sends the screen recording file to the virtual machine, so that the virtual machine acquires the screen recording file. It can be known that, in the second method, the screen recording is realized by means of the desktop image acquisition function, the audio acquisition function and the encoding function of the receiving end module.
It should be noted that, after the receiving end module collects the current frame image and/or the current audio content, on one hand, according to a second screen recording instruction received from the virtual machine, the current frame image and/or the current audio content are encoded according to a target encoding algorithm, and a screen recording file obtained by encoding is returned to the virtual machine; on the other hand, normal desktop image acquisition is still carried out, the acquired desktop image and/or audio content are/is encoded according to another encoding algorithm, and a code stream obtained through encoding is sent to cloud terminal equipment connected with a receiving end module; wherein, another encoding algorithm is an encoding algorithm that can be recognized by the cloud terminal device, for example, vGTP (real-time image compression transport protocol).
And 103, storing the screen recording file in a preset storage space by the virtual machine.
For example, when the screen recording file is obtained by the virtual machine, the screen recording file is stored in a locally preset storage space, for example, the storage space is stored in a system album, and a user of the cloud terminal device can view and use the screen recording file in the system album through remote operation at any time.
It should be noted that the virtual machine may further receive a screen recording stopping request sent by the cloud terminal device, and when the screen recording stopping request is received, send a screen recording stopping instruction to the receiving end module, so that the receiving end module stops sending the current frame image and/or the current audio content to the virtual machine, thereby ending the screen recording operation.
Further, as shown in fig. 3, before executing step 101, the following step 104 is further included:
and 104, the virtual machine sends a desktop display image to the cloud terminal equipment, so that the cloud terminal equipment obtains a screen recording request based on the desktop display image and sends the screen recording request to the virtual machine.
For example, after the cloud terminal device is connected with the virtual machine, the cloud terminal device may receive a desktop display image sent by the virtual machine, the cloud terminal device displays the desktop display image, and when a user sees the desktop display image, if a screen needs to be recorded, the user clicks a screen recording key, so that after acquiring an instruction corresponding to the screen recording key, the cloud terminal device generates a screen recording request, and sends the screen recording request to the virtual machine.
The embodiment of the disclosure provides a screen recording method, wherein when a virtual machine receives a screen recording request of cloud terminal equipment, a screen recording file is obtained based on current playing content obtained by a receiving end module, and finally the obtained screen recording file is stored in a locally preset storage space.
