And then, encoding the screen recording data to obtain the additional video stream recorded aiming at the WeChat window.
Exemplary method
The application window screen recording method in the embodiment can be applied to terminal equipment, and the terminal equipment can be intelligent terminal products such as mobile phones, computers and tablet computers. In specific implementation, the method for recording the application window in the embodiment includes the following steps:
and step S100, acquiring screen data, and determining an application window to be recorded according to the screen data.
In this embodiment, a plurality of applications are generally installed in the terminal device, for example: mango TV, weChat, QQ music, bean cotyledon, etc. In order to meet the use requirement of users, many terminal devices can realize split-screen display, that is, the display screen is divided into a plurality of areas, and different contents are displayed in each area, so that different application windows can be displayed in different areas. For example, the area a displays a WeChat application window, and the area B displays a mango TV application window, so that a user can chat using the WeChat application while watching television using the mango TV. In the existing screen recording operation, the whole screen of the mobile phone is recorded basically, so that some recorded contents are not required by a user. Therefore, when the screen is recorded, the screen data is obtained first, and then the application window to be recorded, which is required to be recorded at the moment, is determined based on the screen data, so that in the subsequent steps, only the application window to be recorded is recorded, and convenience is brought to the use of a user.
In one implementation manner, when determining the window to be recorded, the embodiment specifically includes the following steps:
step S101, acquiring content on a terminal screen to obtain screen data;
Step S102, acquiring layer data of an application window in the screen data;
And step 103, determining the application window to be recorded according to the layer data.
Specifically, the present embodiment is implemented by means of screen recording when acquiring screen data. For example, a screen recording key is arranged in a terminal device (such as a mobile phone), and when a screen recording operation is required, a user firstly records a screen of a terminal screen of the terminal device through the screen recording key, so that screen data are obtained. All applications present in the terminal screen of the terminal device are reflected in the screen data. And then screening the application programs to obtain the application window to be recorded.
In one implementation manner, when the application windows to be recorded are screened, the embodiment determines the application windows based on layer data corresponding to the application windows. Specifically, in this embodiment, first, layer data corresponding to each application window in the screen data is obtained, then, analysis is performed on the layer data, and which or which layer data corresponding application window needs to be recorded is screened out. Firstly, when layer data is obtained, the layer data needs to be classified first, and the purpose of classification is to determine which layer data is the layer data of the application window, so that the application window to be recorded is screened out in the subsequent step. Further, in this embodiment, when recording the screen and generating the layer data of each application window, an identifier is carried, where the identifiers are classified into two types, including a reserved identifier (Scrapp identifier) and a reject identifier (Desapp identifier), so that the embodiment can screen out the application window to be recorded according to the identifier carried in the layer data of each application window.
In particular, in this embodiment, if the identifier in the acquired layer data of a certain application window is a preset reserved identifier (Scrapp identifier), it may be determined that the application window needs to be reserved, that is, needs to be recorded. In order to confirm further, in this embodiment, the layer packet name in the layer data corresponding to the identifier is obtained, then the layer packet name is compared with the name information of the application window, if the layer packet name is the same as the name information of the preset reserved application window, it is indicated that the application window to be recorded window corresponding to the layer data is obtained at this time, and therefore the application window corresponding to the layer data is used as the window to be recorded. If the identifier is a preset rejection identifier (Desapp identifier), the layer packet name in the layer data corresponding to the identifier is obtained, and then the application window corresponding to the layer data is described as being needed to be rejected, so that in order to confirm further, the embodiment obtains the layer packet name in the layer data corresponding to the identifier, and then compares the layer packet name with the name information of the application window. If the name of the layer packet is different from the name information of the preset reject application window, the application window corresponding to the layer data is not the reject application window, and the application window corresponding to the layer data can be used as the window to be recorded. Therefore, the embodiment can classify the application windows according to the layer data, so as to determine the application windows to be recorded.
After determining the window to be recorded, the embodiment may execute step S200, and perform the recording operation on the window to be recorded, to obtain the recording data.
In this embodiment, after determining the application window to be recorded, the application window to be recorded separately is determined, so that the terminal device in this embodiment may perform the recording operation on the application window to be recorded. In this embodiment, the screen recording operation of the application window to be recorded may be implemented by means of screen recording. For example, a screen recording key is arranged in a terminal device (such as a mobile phone), and when a screen recording operation is required, a user firstly records a screen of the application window to be recorded through the screen recording key, so that the screen recording data are obtained. For example, when the window to be recorded is a WeChat application, any operation in the WeChat application window can be recorded, so that the recording data of the WeChat application window can be obtained.
After the screen recording data is obtained, the embodiment executes step S300 to perform encoding processing on the screen recording data, so as to obtain a video stream.
After the screen recording data are obtained, the screen recording data can be subjected to coding processing, and the purpose of the coding processing is to enable the obtained video stream to be normally played and smoothly played.
In one implementation, the method includes the following steps when encoding the recording data:
step S301, acquiring a file header in the screen recording data;
Step S302, if the file header is an SPS frame, acquiring the SPS frame;
step S303, obtaining all I frames in the screen recording data, and adding the SPS frames before each I frame to obtain the video stream.
Specifically, in this embodiment, a header in the recording data is first obtained, then it is determined whether the header is an SPS frame, and if the header is an SPS frame, the SPS frame is obtained. If the file header is not an SPS frame, it is determined whether the file header is an I frame, and if the file header is an I frame, the embodiment may add an SPS frame before the I frame, so that the embodiment may add the SPS frame before each I frame to obtain the video stream, the generated video stream is a video stream in H264 format, and the generated video stream may avoid the problem that the video stream cannot be played during subsequent playing.
In one implementation manner, a ring buffer area is created in advance in the terminal device of the embodiment to receive the video stream, so that the embodiment can buffer the video stream in the preset buffer area, write the video stream into a file, and store the video stream locally. Or after receiving a pushing instruction input by a user, taking out the video stream from the cache area according to the pushing instruction, and pushing the video stream. For example, after obtaining a video stream of a WeChat application, a user wants to view the recorded video stream, can open a local storage space to find a buffer area, and find the video stream from the buffer area. And then playing the video stream to realize the pushing of the video stream of the WeChat application. Therefore, the embodiment can realize the independent recording of the application window to obtain the video stream of the application window, so as to record and save or push the contents of different application windows according to the requirements of users.
In summary, the embodiment obtains screen data, and determines an application window to be recorded according to the screen data; performing screen recording operation on the window to be screen recorded to obtain screen recording data; and carrying out coding processing on the screen recording data to obtain a video stream. According to the embodiment, the screen recording operation can be carried out on a specified application window, so that different application windows can be recorded according to the requirements of a user, and convenience is brought to the user.
