Example one
In order to solve the technical problem of low image rendering efficiency in the prior art, the embodiment of the present disclosure provides a method for implementing rendering isolation by multiple processes. As shown in fig. 1, the method for implementing rendering isolation by multiple processes mainly includes the following steps S11 to S13.
Step S11: acquiring an initial image through a first process, and sending the initial image to a second process; the first process and the second process are two processes which run independently;
the first process may be a main process, the second process may be a sub-process of the first process, and the second process may run in the background. And sharing the resources of the main process and the sub-process. The first Process and the second Process perform information transfer in an Inter-Process Communication (IPC) manner, that is, the first Process sends the image to the second Process by the IPC manner.
In addition, in order to facilitate the second process to perform special effect processing on the image, after the first process acquires the image, the first process may perform preprocessing on the image, including denoising, feature extraction, target recognition and the like, and then send the preprocessed image to the second process.
Specifically, an initial image is obtained from an image input source through the first process, and the initial image may be a video image input in real time, for example, a live video in a short video application, or a video image stored in the terminal in advance. The image may also be a still image, i.e. a picture. The terminal may be a mobile terminal, such as a smart phone or a tablet computer, or a fixed terminal, such as a desktop computer.
The image input source can be a local storage space or a network storage space, the image is obtained from the local storage space or the network storage space through a first process, no matter where the image is obtained, a storage address of the image is preferably required to be obtained, and then the image is obtained from the storage address.
Wherein, the image input source can also be an image sensor, and the image is collected from the image sensor through the first process. The image sensor may be various devices for acquiring images, and typical image sensors are video cameras, still cameras, and the like. In this embodiment, the image sensor may be a camera on the mobile terminal, such as a front-facing or rear-facing camera on a smart phone, and an image acquired by the camera may be directly displayed on a display screen of the smart phone.
This step can be implemented by a custom function. Specifically, the first process may include the following custom functions or objects: VideoStream: the system comprises a user-defined video stream module, an EMVideoPreviewModel user-defined video preview display object, an EMVideoFilterRunable user-defined video frame preprocessing object and an Effect SDKClient user-defined special effect SDK interface object. Specifically, a video frame is read through a VideoStream as an initial image, the initial image is transmitted to an EMVideoPreviewModel object, an EMVideoPreviewModel is accessed through a QML layer, image data is sent to an EMVideoFilterRunable, the video frame is preprocessed through the EMVideoFilterRunable, image data to be displayed is sent to an effect sdkclient processing module, and the effect sdkclient processing module transmits the image data to an independent sub-process, namely, a second process through inter-process communication for special effect processing.
Step S12: and responding to the special effect editing operation of the user on the initial image, carrying out special effect processing on the initial image through the second process to obtain a special effect image, and sending the special effect image to the first process.
The special effect processing may be, for example, extracting a target object (e.g., a human face), adding a sticker (e.g., a human face sticker), and the like.
Step S13: displaying the special effect image through the first process.
Specifically, the special effect image can be displayed in real time through an Output control of a universal video playing component in the QML.
In the embodiment, the image rendering and the special effect processing are respectively realized through the two processes, so that the time consumption caused by the special effect processing of the second process can be avoided, the image rendering efficiency of the first process can be improved due to the influence on the image rendering of the first process, and the operation of the other process is not influenced when the process is blocked, so that the image processing efficiency is further improved.
In an alternative embodiment, the first process and the second process are implemented based on the ANGLE framework.
Almost Native Graphics Layer Engine (ANGLE) projects implement a Web GL subset interface in a Layer of OpenGL ES 2.0API on the basis of Direct X9.0 c API. Among them, Direct X (DX) is a multimedia Programming Interface created by microsoft corporation, and is an Application Programming Interface (API). Among them, OpenGL ES (OpenGL for Embedded Systems) is a subset of OpenGL three-dimensional graphics API. OpenGL (Open Graphics Library, Open Graphics Library or Open Graphics Library) is a cross-language, cross-platform application programming interface for rendering two-dimensional, three-dimensional vector Graphics.
Specifically, the image rendering and special effect processing processes are respectively extracted and divided into two processes to be realized, namely a first process is used for realizing image rendering, and a second process is used for special effect processing. And, both processes are implemented based on ANGLE.
In an alternative embodiment, the first process is a descriptive scripting language QML rendering thread, and the second process is a special effects software development kit Effect SDK.
In the prior art, in the ANGLE mode, Qt switches the descriptive scripting language Qml rendering thread to the main thread, and OpenGL is also used for calling the Effect SDK, which is a special Effect software development package, in the prior art, the Effect SDK must be called in the main thread due to the limitation of multithreading, but the Effect SDK special Effect processing is very time-consuming, which greatly reduces the rendering frame rate of Qml.
Therefore, in this embodiment, the main thread where QML rendering is located is taken as the first process, and the Effect SDK is isolated from the main thread as an independent sub-process, i.e., the second process. Therefore, the time consumption caused by Effect SDK special Effect processing and the influence on QML image rendering can be avoided, the image rendering efficiency can be improved, and in addition, when the main thread Crash is adopted, the subprocess can still run.
In an optional embodiment, the first process and the second process are implemented based on OpenGL.
The OpenGL may be an original OpenGL. The method can be realized based on the conventional OpenGL, and can be realized by extracting an image rendering function and an image special effect processing function and then respectively adopting different processes. Namely, the first process is used for realizing the image rendering function, the second process is used for realizing the image special effect processing function, and the processing result of the second process is called to render in the executing process of the first process.
It will be appreciated by those skilled in the art that obvious modifications (for example, a superposition of the modes listed) or equivalent substitutions may be made on the basis of the various embodiments described above.
In the above, although the steps in the embodiment of the method for implementing rendering isolation by multiple processes are described in the above sequence, it should be clear to those skilled in the art that the steps in the embodiment of the present disclosure are not necessarily performed in the above sequence, and may also be performed in other sequences such as reverse, parallel, and cross, and further, on the basis of the above steps, those skilled in the art may also add other steps, and these obvious modifications or equivalent alternatives should also be included in the protection scope of the present disclosure, and are not described in detail herein.
For convenience of description, only the relevant parts of the embodiments of the present disclosure are shown, and details of the specific techniques are not disclosed, please refer to the embodiments of the method of the present disclosure.
