Description
Technical Field
The present disclosure relates to the field of image processing technologies, and in particular, to an image overturning method and apparatus, an electronic device, and a storage medium.
Background
Currently, a media processing software platform (Media Process Platform, abbreviated as MPP) can support rapid development of application software. The platform shields the complex bottom layer processing related to the chip from the application software, and directly provides MPI (MPP Programe Interface) interfaces for the application software to complete corresponding functions. The platform supports the application software to rapidly develop the following functions: input video capturing, H.264/MJPEG/JPEG/MPEG4 encoding, H264/H.265/VC1/MPEG4/MPEG2/AVS decoding, video output display, video image preprocessing (including denoising, enhancement, sharpening, decryption), code stream superposition OSD, video detection analysis, intelligent analysis, audio capturing and output, audio encoding and decoding, and the like.
The MPP platform provides a video decoding module (VDEC module), an image processing module (VPSS module), a video rendering module (VOU module), etc.: the VDEC module provides an MPI interface for driving video decoding hardware to work so as to realize a video decoding function; the VPSS module (Video Process Sub-System) supports unified preprocessing of an input image, such as denoising, de-interlacing and the like, then performs scaling, sharpening and the like on each channel respectively, and finally outputs images with different resolutions; the VOU module (Video Output Unit) module actively reads video and graphic data from corresponding positions in the memory and outputs the video and graphic data through corresponding display devices.
In the actual use process, the MPP platform transmits media (i.e. video coding stream) to the VDEC module, and the MPP completes subsequent processing.
In the actual use process, many scenes require video images on demand to be overturned, but the VPSS module of the MPP can only overturn the images according to the fixed overturning angle realized by the VPSS, so that the MPP platform can only overturn the images at the fixed overturning angle. Moreover, the MPP platform in the related art cannot perform other flipping modes beyond those that can be realized by the VPSS in an embedded manner.
Therefore, the technical problem that the media processing software platform cannot be expanded in an embedded manner exists in the related art.

In order to make the present application solution better understood by those skilled in the art, the following description will be made in detail and with reference to the accompanying drawings in the embodiments of the present application, it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, shall fall within the scope of the present application.
It should be noted that the terms "first," "second," and the like in the description and claims of the present application and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that embodiments of the present application described herein may be implemented in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
According to one aspect of the embodiments of the present application, an image flipping method is provided. Alternatively, in the present embodiment, the above-described image flipping method may be applied to a hardware environment constituted by the terminal 1402 and the server 1404 as shown in fig. 4. As shown in fig. 1, the server 1404 is connected to the terminal 1402 via a network, and may be used to provide services (such as game services, application services, etc.) to the terminal or clients installed on the terminal, and a database may be provided on the server or independent of the server, for providing data storage services to the server 1404.
The network may include, but is not limited to, at least one of: wired network, wireless network. The wired network may include, but is not limited to, at least one of: a wide area network, a metropolitan area network, a local area network, and the wireless network may include, but is not limited to, at least one of: WIFI (Wireless Fidelity ), bluetooth. The terminal may not be limited to a PC, a mobile phone, a tablet computer, or the like.
The image flipping method in the embodiment of the present application may be executed by a server, may be executed by a terminal, or may be executed by both the server and the terminal. The terminal may also execute the image flipping method according to the embodiment of the present application by a client installed thereon.
Taking the image flipping method in the present embodiment performed by a server as an example, fig. 1 is a flowchart of an image flipping method provided in the present embodiment, including the following steps:
step S101, a target virtual address is obtained from an image processing channel, and the target virtual address is converted into a target physical address, wherein the image processing channel is a channel for image processing in a target media processing software platform.
The image flipping method in the present embodiment may be applied to a scene where a media processing software platform (e.g., MPP platform (Media Process Platform)) needs to output a flipped image, for example: the scene of outputting the horizontally flipped image, the scene of outputting the vertically flipped image, etc., may be a scene of other image flipping modes.
Specifically, the image processing channels may be channels in a VPSS (Video Process Sub-System, image processing module) for processing images, where the VPSS supports unified preprocessing, such as denoising, de-interlacing, etc., for an input image, and then performs scaling, sharpening, etc. on each channel, and finally outputs images with multiple different resolutions.
That is, different image processing channels may be used to output images of different resolutions and/or degrees of sharpening.
The target virtual address may have a uniquely corresponding target physical address. The interface of the channel acquisition data in the VPSS returns a mapping of the physical memory address of the image data, called virtual memory address, which can be converted to each other by the associated MPI in the media processing software platform.
In this embodiment, the target virtual address may be converted through a preset data conversion interface to be converted into an actually available target physical address, that is, the external world may acquire data through the target physical address.
Step S102, acquiring target image data in a target physical address.
Specifically, after the target physical address is acquired, since the target physical address is truly accessible, target image data can be acquired from the target physical address.
Step S103, the target image data is overturned according to a preset overturned mode, and overturned image data are obtained.
Specifically, after the target image data is acquired, the target image data can be turned over according to a preset turning-over mode.
In general, the preset turning mode is a turning mode which cannot be realized by the media processing software platform where the image processing channel is located, for example, when the media processing software platform can only realize a turning mode which is upside down and the required turning mode is left-right interchanged; the preset turning mode is left-right exchange, and when the turning mode is needed to be turned upside down, the media processing software platform is directly adopted for realizing the turning mode.
In this embodiment, the target image data is obtained in an embedded manner, and after being turned over, the turned-over image data is obtained.
For example, when the preset turning mode is left-right turning, the image data after turning is the image data after left-right exchange with the target image data.
Step S104, writing the turned image data into a data reading module, and rendering and playing the turned image data through the data reading module, wherein the data reading module is a module for reading the image data and rendering and playing in a target media processing software platform.
Specifically, after the flipped image data is acquired, the flipped image data needs to be output.
In this embodiment, the data reading module may actively read the flipped image data by writing the flipped image data into the data reading module, or may perform the action of writing the flipped image data into the data reading module by other modules.
The data reading module can render the overturned image data after acquiring the overturned data and play the overturned image data through corresponding display equipment.
In addition, in this embodiment, the data reading module and the image processing module where the image processing channel is located belong to the same media processing software platform.
Still taking the MPP platform as an example, the data reading module may be a VOU (Video Output Unit) module, and the VOU module may actively read the flipped image data from the corresponding position in the memory, and output the flipped image data through the corresponding display device.
The method in the embodiment comprises the steps of acquiring a target virtual address from an image processing channel, converting the target virtual address into a target physical address, further acquiring target image data in the target physical address, acquiring the target virtual address from the image processing channel, converting the target virtual address into the target physical address, further acquiring the target image data in the target physical address, then overturning the target image data according to a preset overturning mode to obtain overturned image data, and finally rendering and playing through a data reading module, so that the aim of overturning the target image data according to the preset overturning mode is realized between the image processing channel and the data reading module in an embedded mode; because the preset turning mode is a turning mode which can be arbitrarily set according to the requirement, other turning modes besides the turning mode which can be performed by the media processing software platform can be realized; and the technical problem that the media processing software platform cannot be expanded in an embedded manner in the related technology can be effectively solved.
As an optional embodiment, as in the foregoing method, before the step S103 of flipping the target image data according to the preset flipping manner to obtain flipped image data, the method further includes the following steps:
initializing an image overturning library; and configuring the image overturning library according to a preset overturning mode to obtain the configured image overturning library.
Specifically, a turnover module in the image turnover library is initialized, and then the turnover module is configured according to a preset turnover mode, so that the turnover module can be used for turning over the image according to the preset turnover mode.
For example, the image roll-over library may be FFMPEG (a powerful and widely used set of open source multimedia processing tools, providing rich functionality and tools for processing audio, video, and multimedia streams as a cross-platform tool), which may run on a variety of operating systems, including embedded software platforms. Further, the flip module may be an avfilter module in FFMPEG.
The target image data is overturned according to a preset overturned mode to obtain overturned image data, and the method comprises the following steps:
after the configured image overturning library is obtained, overturning the target image data through the configured image overturning library to obtain overturning image data obtained by overturning according to a preset overturning mode.
As an alternative embodiment, as the foregoing method, the step S104 writes the flipped image data into the data reading module, and renders and plays the flipped image data through the data reading module, which includes the following steps:
converting the appointed physical address of the flipped image data into an appointed virtual address; and sending the appointed virtual address to the data reading module so that the data reading module obtains the flipped image data according to the appointed virtual address, and rendering and playing the flipped image data.
After the flipped image data is obtained, that is, the flipped image data needs to be stored, the designated physical address of the flipped image data storage may be the target physical address (that is, the target image data is replaced by the flipped image data), or the designated physical address may be a different target physical address (that is, the flipped image data storage location is different from the target image data).
The data reading module can only read data according to the virtual address, so that the appointed physical address of the flipped image data is converted into the appointed virtual address; and sending the appointed virtual address to the data reading module so that the data reading module obtains the flipped image data according to the appointed virtual address, and rendering and playing the flipped image data.
As an alternative embodiment, as the foregoing method, before the step S101 of obtaining the target virtual address from the image processing channel and converting the target virtual address into the target physical address, the method further includes the following steps:
establishing an association relationship between a data source and an image processing module, wherein the data source is used for sending decoded data to the image processing module, and the image processing module comprises at least one image processing channel;
and transmitting the image data to be processed to the image processing module through the data source.
Specifically, in this embodiment, the data source may be a VDEC module in the MPP platform (an MPI interface for driving the video decoding hardware to work is provided, so as to implement the video decoding function).
The media processing software platform may be initialized in advance, then a data source (VDEC module), an image processing module (VPSS module) and a data reading module (VOU module) are created, and then an association relationship between the data source and the image processing module is established by binding the data source and the image processing module. After the association relation is established, the data generated by the data source is automatically sent to the image processing module.
As an alternative embodiment, as the aforementioned method, before the step of transmitting the image data to be processed to the image processing module via the data source, the method further comprises:
step 201, judging whether the image data to be processed needs to be overturned according to a preset overturned mode;
step 202, after determining that the image data to be processed needs to be flipped according to the preset flipping manner, transmitting the image data to be processed to the image processing module through the data source, performing a jumping operation for jumping to the step to obtain the target virtual address from the image processing channel, and converting the target virtual address into the target physical address.
Step 203, under the condition that the image data to be processed is determined not to need to be overturned according to a preset overturned mode, establishing an association relationship between the image processing module and the data reading module; and after the image processing module processes the image data to be processed to obtain processed image data, outputting the processed image data through the data reading module.
Specifically, after the data source (VDEC module), the image processing module (VPSS module) and the data reading module (VOU module) are created, it may be determined whether the image data to be processed needs to be turned according to a preset turning manner, that is, whether the image data to be processed needs to be processed in an image turning manner which cannot be achieved by the media processing software platform.
In the case that it is determined that the image data to be processed needs to be flipped according to the preset flipping manner, it is indicated that the processing capability of the media processing software platform cannot meet the requirement, so that after the image data to be processed is transmitted to the image processing module through the data source, a skipping operation for skipping to step S101 is performed.
Under the condition that the image data to be processed does not need to be overturned according to a preset overturned mode, the processing capability of the media processing software platform is indicated to meet the requirement, and the association relationship between the image processing module and the data reading module is directly established; and after the image processing module processes the image data to be processed to obtain processed image data, outputting the processed image data through the data reading module. Taking the MPP platform as an example: after the VDEC binds with the VPSS, the decoded image data of the VDEC is automatically sent to the VPSS module, and after image processing, the decoded image data is automatically sent to the VPSS-bound VOU.
As an optional embodiment, after sending the specified virtual address to the data reading module to enable the data reading module to obtain the flipped image data according to the specified virtual address, and render and play the flipped image data, a method as described above further includes:
and releasing the target physical address and the appointed physical address.
That is, after the rendering and playing of the flipped image data are completed, the target physical address and the designated physical address related to the flipped image data can be released, so that the memory can be released, and the occupation of resources can be reduced.
As shown in fig. 2, an application example of applying any of the foregoing embodiments in the MPP platform is as follows:
1. initializing an MPP platform;
2. creating VDEC, creating VPSS, and creating VOU; and binding the VDEC with the VPSS; binding is to establish an association relationship between a data source and a data receiver. After binding, the data generated by the data source will be automatically sent to the recipient. For example, after the VDEC binds to the VPSS, the decoded image data of the VDEC is automatically sent to the VPSS module, and after the image processing, the decoded image data is automatically sent to the VPSS-bound VOU.
3. Under the condition that the image needs to be overturned according to a preset overturned mode, the VPSS acquires image data from the VDEC, and then converts a virtual address for highlighting the data into a physical address; and the image data is overturned through FFMPEG, the overturned image data is obtained, the physical address of the overturned image data is converted into a virtual address, the VOU acquires the overturned image data according to the virtual address of the overturned image data, and finally the overturned image data is output by the VOU.
Further, in the case that the image needs to be turned over according to a preset turning mode, the steps of the main function call flow chart are as follows:
[1]: and initializing an avfilter module of FFMPEG for performing a flipping operation on the image.
[2]: one frame of data (i.e., a virtual address corresponding to one frame of image data) is acquired from the VPSS path.
[3] For initializing the flip mode of the avfilter module.
[4]: the virtual address is translated to a physical address.
[5]: and transmitting the image data to FFMPEG for processing and turning over to obtain turned-over image data.
[6]: and converting the physical address of the flipped image data into a virtual address, and sending the virtual address to the VOU for rendering and playing.
[7]: and sending the flipped image data to the VOU for rendering and playing.
[8]: releasing the physical memory address.
4. Under the condition that the image does not need to be overturned according to a preset overturning mode, the VPSS binds the VOU, and then the image data processed by the VPSS is directly output by the VOU.
