Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. 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.
According to an embodiment of the present invention, there is provided a video watermarking method embodiment, it should be noted that the steps shown in the flowchart of the figure may be executed in a computer system such as a set of computer executable instructions, and that although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in an order different from that here.
In this embodiment, a video watermarking method is provided, which can be used in a scene that needs to be watermarked, as shown in fig. 1, where the video watermarking method includes the following steps:
step S1: and sequentially acquiring the current video frame image and the watermark content to be added to the current video frame image from the target video.
Step S2: and screening second watermark data corresponding to the watermark content from the first watermark data preloaded in the memory.
Step S3: and overlaying the second watermark data on the current video frame image.
Specifically, as the watermarks of each frame of image in the video may be different, in the video playing process, time consumption is long according to the existing method of generating the image and transcoding again, and especially under the condition that the watermark in the video changes rapidly, the processing speed cannot keep up, and the video is blocked.
Through the steps S1 to S3, the video watermark adding method provided in the embodiment of the present invention directly screens the watermark data corresponding to the watermark content and capable of directly covering the video frame image from the memory, so as to omit the process of generating the watermark content into a picture and transcoding the picture, increase the processing speed of the watermark, and effectively avoid the problem that the video is jammed due to long time consumed for watermark processing.
Specifically, in an embodiment, the first watermark data preloaded in the internal memory in the step S2 is obtained as shown in fig. 2 in the following manner:
step S21: and analyzing the target video to obtain the running scene of the target video. Specifically, by performing identification analysis on the scene, for example, the operation scene is related to vehicle speed or time, the watermark content is likely to be the vehicle speed or time.
Step S22: based on the operation scene, first watermark data relevant to the operation scene is called from a watermark database. Specifically, a large amount of watermark data is stored in the watermark database, and the watermark data related to the operation scene can be extracted from the watermark database based on the operation scene.
Step S23: and preloading the first watermark data into the memory. Specifically, the first watermark data is preloaded into the memory, so that subsequent direct calling is facilitated, and the watermark adding efficiency is effectively improved.
Specifically, in an embodiment, as shown in fig. 2, the obtaining of the first watermark data preloaded in the memory further includes the following steps:
step S24: and transcoding the watermark content which needs to be added to the current video frame image to obtain third watermark data which can be directly covered.
Step S25: and storing the third watermark data in a watermark database.
Specifically, the process is to continuously enrich the stock of the watermark database and provide stronger data support for later calling of watermark data.
Specifically, in an embodiment, as shown in fig. 3, the step S25 includes the following steps:
step S251: and classifying the third watermark data according to the operation scene of the watermark content.
Step S252: and storing the classified third watermark data into a watermark database.
Specifically, the third watermark data is classified and then stored, so that the watermark data can be called based on the operation scene conveniently.
Specifically, in an embodiment, as shown in fig. 4, the video watermarking method further includes the following steps:
step S41: and acquiring the use frequency of the first watermark data preloaded in the memory. Specifically, since the first watermark data is called according to the running scene, part of the first watermark data may be unavailable or used less frequently.
Step S42: and deleting the first watermark data with the use frequency lower than the preset frequency threshold from the memory. Specifically, in order to reduce the occupation of the memory and increase the processing speed, the first watermark data pre-loaded in the memory is dynamically updated, and the first watermark data with the use frequency lower than the preset frequency threshold is deleted from the memory.
Specifically, in an embodiment, as shown in fig. 5, the video watermarking method further includes the following steps:
step S51: and acquiring a plurality of watermark contents to which the target video is added.
Step S52: and establishing a watermark prediction model based on the plurality of watermark contents, and predicting the subsequent predicted watermark contents needing to be added according to the watermark prediction model.
Step S53: and judging whether the first watermark data preloaded in the memory has watermark data which is consistent with the predicted watermark content.
Step S54: if the predicted watermark content does not exist, the predicted watermark content is compared with the watermark database, and watermark data corresponding to the predicted watermark content is extracted from the watermark database and loaded into the memory.
Specifically, the watermark data which is possibly needed subsequently is predicted according to the watermark content, and the watermark data which is not preloaded into the memory is loaded into the memory in advance through prediction, so that the processing speed of the watermark is accelerated. For example watermarking vehicle related video:
1. the watermark display content is related to the vehicle speed, and different content is displayed at different vehicle speeds. And predicting the vehicle speed at the next moment according to the characteristic of continuous change of the vehicle speed, predicting the watermark content according to the relation between the vehicle speed and the watermark content, and extracting the required watermark data from the watermark database in advance according to the watermark content and loading the watermark data into the memory.
2. The watermark shows that the content is time dependent, with different time showing different content. Because the time is forward in a single direction, the watermark content at the next moment is calculated according to the relation between the time and the watermark content, and the needed watermark data is extracted from the watermark database in advance according to the watermark content and loaded into the memory.
3. The watermark shows that the content is location dependent and different locations show different content. Since the location is continuously variable for a running vehicle. The location of the next moment can be presumed according to the location movement change rule of the current moment, the watermark content is predicted according to the relation between the location and the watermark content, and the needed watermark data is extracted from the watermark database in advance according to the watermark content and loaded into the memory.
Specifically, in an embodiment, as shown in fig. 5, the video watermarking method further includes the following steps:
step S55: and if the watermark data which is consistent with the predicted watermark content does not exist in the watermark database, generating a watermark picture according to the predicted watermark content.
Step S56: and transcoding the watermark picture to obtain predicted watermark data.
Step S57: and loading the predicted watermark data into a memory, and storing the predicted watermark data into a watermark database.
Specifically, when the watermark database does not have the watermark data which is consistent with the predicted watermark content, the watermark data is obtained through the traditional processing process according to the predicted watermark content and is loaded to the memory and stored in the watermark database, so that when the watermark data needs to be called, the corresponding watermark data is stored in the memory, and the watermark adding speed is effectively improved; and by storing the predicted watermark data into the watermark database, more powerful data support is provided for later watermark data invocation.
