Description

Technical Field

[0001] The present invention relates to information processing technology, and in particular to a video information processing method, device, system, electronic device and storage medium. Background Art

[0002] In the related art, when playing animations, not only are the playback styles becoming increasingly rich, but the visual effects are also becoming increasingly rich. In particular, for software with social information interaction, if a transparent animation can be appropriately played during the communication between the two communicating parties, the user's visual experience can be greatly enhanced without affecting the communication between the two communicating parties in viewing the content of the communication in the chat box. Therefore, a transparent playback style is usually used to play animations. In order to achieve transparent animations, an image file storage format with transparency information (PNGPortable Network Graphic Format) is usually used to achieve this. Among them, a PNG sequence is essentially an animation resource package composed of multiple images, each of which has transparency information. By decoding and playing this animation resource package, a transparent animation is achieved. However, this method of using an animation resource package composed of multiple images is usually very large, so the decoding time will be very long, and it will occupy a large amount of memory, resulting in poor efficiency of this animation playback method, affecting the user's experience.

It can be understood that: Figure 3 The steps shown can be performed by various servers running video information processing devices, such as dedicated terminals, servers, cloud servers or server clusters with video information processing functions. Figure 3 The steps shown are explained.

[0110] Step 301: The video information processing apparatus obtains original image frames of a target video and a corresponding original image frame sequence.

[0111] In some embodiments of the present invention, obtaining the original image frames of the target video and the corresponding original image frame sequence can be achieved by:

[0112] Based on the initialization parameters of the target video, the starting position and the ending position of the target video are determined; the target video is sliced ​​according to the starting position and the ending position to form slices of the target video; the original image frames of the target video are determined according to the slices of the target video, and the corresponding original image frame sequence is determined according to the parameter information of the original image frames of the target video. Furthermore, according to different usage scenarios, the code stream of the target video signal and the code stream of the target video signal can be encapsulated into new multimedia information to form multimedia information to be on demand; or the formed multimedia information can be pushed to the terminal 10 through the network 40.

[0113] In some embodiments of the present invention, when processing the target video, the target video is first initialized, and two consecutive frames of images are extracted from the target video through the processing queue of the image processor GPU, namely the first frame image T-1 and the second frame image T. Since the noise of each frame image in the target video shot under dark light conditions usually satisfies the Gaussian distribution, when removing the noise of the image frame, the extracted first frame image T-1 and the second frame image T are first Gaussian blurred to improve the operating efficiency of the image processor GPU.

[0114] Step 302: The video information processing device performs a first conversion process on the original image frames of the target video according to the original image frame sequence of the target video, and determines the common chromaticity value parameters of adjacent pixel points in the pixel array of the corresponding fused image frame.

[0115] In some embodiments of the present invention, performing a first conversion process on the original image frames of the target video according to the original image frame sequence of the target video and determining the common chromaticity value parameters of adjacent pixels in the pixel array of the corresponding fused image frame can be achieved by:

[0116] According to the original image frame sequence of the target video, the original image frame of the target video is converted from a three-primary color encoding method to a grayscale value encoding method; the chromaticity value parameter of each pixel in the original image frame of the grayscale value encoding method is determined; based on the original image frame sequence of the target video, adjacent pixels in the pixel array of the original image frame are determined, and based on the chromaticity value parameter of each pixel in the original image frame, a common chromaticity value parameter of adjacent pixels in the pixel array of the corresponding fused image frame is determined. The video information processing method provided by the present invention can be applied to various scenarios, especially for use environments with social information interaction functions. During the communication process between the two communicating parties, playing the video at a suitable time can significantly improve the user experience. Video playback can be triggered by certain conditions. The triggering condition for video playback can be that the communication information sent by the two communicating parties during the communication includes a keyword that can trigger an animation effect; or the user activates a function in the software application that has an animation playback effect, such as when the gift sending function is activated, an animation effect about the gift giving process can be played. The embodiment of the present invention does not specifically limit the form of the above triggering condition. Furthermore, currently, in order to avoid affecting the communication between the two parties in viewing the content of the chat box, the animation videos played are usually transparent animation videos. In order to solve the problems of high memory consumption and poor playback performance when playing transparent animations, the embodiment of the present invention proposes a method of using a video file with a specific format as the carrier of the animation and playing the animation through a native player. The specific format can be the fourth version of the Moving Pictures Experts Group (MP4) or the streaming media format (FLV Flash Video), etc., which is not specifically limited in the embodiment of the present invention.

[0117] In some embodiments of the present invention, determining the common chromaticity value parameters of adjacent pixels in the pixel array of the corresponding fused image frame based on the chromaticity value parameters of each pixel in the original image frame can be achieved by:

[0118] Based on the color parameters in the chromaticity value parameters of each pixel point in the original image frame, the common color parameters of adjacent pixel points in the pixel array of the corresponding fused image frame are determined; based on the saturation parameters in the chromaticity value parameters of each pixel point in the original image frame, the common saturation parameters of adjacent pixel points in the pixel array of the corresponding fused image frame are determined.

[0119] In some embodiments of the present invention, performing a second transformation on the first transformation result of the original image frame of the target video based on the common chromaticity value parameter of the adjacent pixels to form a fused image frame can be achieved by:

[0120] Based on a mapping relationship matching the target video, the color parameters of the chromaticity value parameters of each pixel in the original image frame are replaced by the common color parameters of adjacent pixels in the pixel array of the fused image frame; based on a mapping relationship matching the target video, the saturation parameters of the chromaticity value parameters of each pixel in the original image frame are replaced by the common saturation parameters of adjacent pixels in the pixel array of the fused image frame; and transparent channel information matching the original image frame of the target video is filled into the pixel array to form a fused image frame carrying transparent channel information. Since the color parameters of the chromaticity value parameters of each pixel in the original image frame are replaced by the common color parameters of adjacent pixels in the pixel array of the fused image frame, the volume of the pixel array of the fused image frame is significantly smaller than that of the original image frame, thereby maximally filling the transparent channel information matching the original image frame of the target video into the pixel array to form the fused image frame carrying transparent channel information. Thus, by compressing the volume of the fused image frame, the volume of the target video can also be effectively compressed.

[0121] Step 303: The video information processing device performs a second conversion process on the first conversion process result of the original image frame of the target video based on the common chromaticity value parameters of the adjacent pixel points to form a fused image frame.

[0138] Combine Figure 2 The terminal 10-1 shown illustrates the video information processing method provided by the embodiment of the present invention, see Figure 5 , Figure 5 This is an optional flow chart of the video information processing method provided by the embodiment of the present invention. It can be understood that: Figure 5 The steps shown can be performed by various electronic devices running video information processing devices, such as dedicated terminals with video information processing functions, video players. Figure 5 The steps shown are explained.

[0139] Step 501: When the playback process corresponding to the stored video stream information is triggered, the video stream information is obtained, and the video stream information is decoded to determine the corresponding fused image frame.

[0140] The fused image frame carries corresponding transparent channel information.

[0141] Step 502: Perform a third transformation process on the fused image frame to determine the chromaticity value parameter of each pixel in the fused image frame.

[0142] In some embodiments of the present invention, performing the third conversion process on the fused image frame to determine the chromaticity value parameter of each pixel in the fused image frame can be achieved by:

[0143] According to the sequence of the fused image frames, based on the common chromaticity value parameters of adjacent pixels in the fused image frame, the color parameters in the chromaticity value parameters of each pixel in the original image frame are determined; according to the sequence of the fused image frames, based on the common saturation parameters of adjacent pixels in the fused image frame, the saturation parameters in the chromaticity value parameters of each pixel in the original image frame are determined.

[0144] Step 503: Based on the chromaticity value parameters of each pixel in the fused image frame, perform a fourth transformation on the result of the third transformation of the fused image frame to form a corresponding original image frame.

[0145] In some embodiments of the present invention, performing a fourth transformation on the result of the third transformation of the fused image frame based on the chromaticity value parameter of each pixel in the fused image frame to form a corresponding original image frame can be achieved by:

[0146] Based on the color parameters and saturation parameters in the chromaticity value parameters of each pixel point in the original image frame, the third conversion processing result of the fused image frame is converted from the grayscale value encoding method to the three primary color encoding method to form the corresponding original image frame.

[0147] Step 504: Based on the transparent channel information, the transparency of the original image frame is adjusted, and the original image frame is subjected to video encoding processing to form a corresponding target video.

[0148] Combine Figure 2 The terminal 10-1 and the server 200 are shown to illustrate the video information processing method provided by the embodiment of the present invention. Figure 6 , Figure 6 This is an optional flow chart of the video information processing method provided by the embodiment of the present invention.

Figure 6 The steps shown are explained.

[0149] Step 601: Acquire original image frames of a target video and a corresponding original image frame sequence.

[0150] Step 602: performing a first conversion process on the original image frames of the target video according to the original image frame sequence of the target video, and determining common chromaticity value parameters of adjacent pixels in a pixel array of a corresponding fused image frame.

[0151] Among them, for each picture in the PNG sequence, it contains an Alpha channel, wherein the Alpha channel is a special layer for recording transparency information. For example, a picture stored using 16 bits may have 5 bits representing red (R), 5 bits representing green (G), 5 bits representing blue (B), and 1 bit representing transparency. In this case, the picture is either completely transparent or completely opaque. For a picture stored using 32 bits, red, green, blue and transparency can be represented every 8 bits. In this case, in addition to representing complete transparency and complete opacity, the Alpha channel can also represent 256 levels of translucency. The Alpha value ranges from 0 to 1. Among them, 1 represents complete opacity and 0 represents complete transparency. In an embodiment of the present invention, the transparency parameter refers to the above-mentioned Alpha value. Among them, in addition to RGB values, color parameter values ​​can also be represented as YUV values.

[0152] Step 603: Based on the common chromaticity value parameters of the adjacent pixels, a second transformation is performed on the first transformation result of the original image frame of the target video to form a fused image frame, wherein the fused image frame carries transparent channel information that matches the original image frame of the target video.

[0153] Step 604: performing video encoding processing on the fused image frame according to the original image frame sequence to form corresponding video stream information to be stored.

[0154] Step 605: When the playback process corresponding to the stored video stream information is triggered, the video stream information is obtained, and the video stream information is decoded to determine a corresponding fused image frame, wherein the fused image frame carries corresponding transparent channel information.

[0155] Step 606: Perform a third transformation process on the fused image frame to determine the chromaticity value parameter of each pixel in the fused image frame.

[0156] Step 607: Based on the chromaticity value parameters of each pixel in the fused image frame, perform a fourth transformation on the result of the third transformation of the fused image frame to form a corresponding original image frame.

[0157] Step 608: Based on the transparent channel information, adjust the transparency of the original image frame, and perform video encoding processing on the original image frame to form video stream information of corresponding transparency.

[0158] The following uses the target video as an animation as an example to illustrate the video information processing method provided by this application. Figure 1 In the illustrated usage environment, transparent animations can be played using formats such as PNG sequences, APNG images, GIF images, and MP4. PNG sequences and APNG images are large in size, consume significant performance overhead when decoded into bitmaps, and consume significant memory during playback, making them unsuitable for high-resolution and long-duration animations. GIF animations, however, lack transparency information, as they contain only 0s and 1s, and their clarity and frame rate are low after compression, making them unsuitable for large animation playback. While transparent MP4 can support transparent animation playback, it requires expanding the width or height of the image to twice the original size, storing half the RGB information and the other half the transparency information, or expanding the width or height to 4 / 3 of the original size, with the remaining 1 / 3 used for the transparency information. This also requires a larger viewing area for the animation. This increases the size of the animation file, memory usage, and CPU usage during the decoding process on the phone. In scenarios where full-screen animation playback is required, excessive memory usage can impact other terminal processes.

[0159] refer to Figure 7 , Figure 7 An optional flow chart of a video information processing method provided in an embodiment of the present invention is provided. To solve the above-mentioned problem, an embodiment of the present invention provides a video information processing method, comprising the following steps:

[0160] Step 701: Acquire a sequence of image frames of a target video.

[0161] Traditional animation formats (such as MP4) don't support transparent display. The decoded image data only contains the RGB channel triplet. To support transparent playback, the alpha channel (αChannel or Alpha Channel) must be stored in each frame. In existing methods, each image in the data source (PNG sequence) includes an alpha channel, but this information is lost when the animation is synthesized.

[0162] Step 702: Process the image frame of the target video to form a pair of UV values ​​shared by two adjacent pixels.

[0163] Among them, reference Figure 8 , Figure 8 A schematic diagram of video encoding of an original image frame using the video information processing method provided in an embodiment of the present invention. In the process of converting the RGB image frame to YUV, two adjacent pixels can share a pair of UV values, saving exactly 1 / 3 of the space for each pixel. The saved space can be used to store the alpha channel information corresponding to the pixel.

[0164] refer to Figure 9 and Figure 10 , Figure 9 A schematic diagram of the encoding effect of the video information processing method provided by an embodiment of the present invention is provided. Figure 10 A schematic diagram of the encoding effect of the video information processing method provided in an embodiment of the present invention, wherein, since the color parameters in the chromaticity value parameters of each pixel point in the original image frame are replaced by the common color parameters of adjacent pixels in the pixel array of the fused image frame, the volume of the pixel array of the fused image frame is significantly smaller than the volume of the original image frame, thereby achieving the maximum extent of filling transparent channel information matching the original image frame of the target animation into the pixel array, forming a fused image frame carrying transparent channel information. Therefore, by compressing the volume of the fused image frame, the volume of the target animation can also be effectively compressed.

[0165] Step 703: triggering the ffmpeg process to convert the processed image frame sequence into a corresponding mp4 format file.

[0166] Step 704: When the target video is in the playing state, the corresponding MP4 format file is converted to form a transparent animation.

[0167] Among them, reference Figure 11 and Figure 12 , Figure 11 A schematic diagram of video decoding of an original image frame by a video information processing method provided by an embodiment of the present invention is provided. Figure 12 A schematic diagram of the decoding effect of the video information processing method provided in an embodiment of the present invention, wherein, during the animation playback process, the animation file generated in the previous step can be played. Before playback, it is necessary to restore the image obtained from the animation and convert the image frame from YUV format to RGB format to form a transparent animation.

[0168] Furthermore, the preceding steps may be processed by the CPU or GPU of the terminal. In this process, GPU processing is preferably used to reduce the load on the terminal CPU.

[0169] Compared with the transparent video solution used in traditional technology, refer to Table 1,

[0170]

[0171] Table 1

[0172] The technical solution provided by this application can not only effectively reduce the storage space required for animation, but also shorten the decoding time, improve the fluency of user use, and thus effectively improve the user experience.

[0173] Beneficial technical effects:

[0174] The embodiment of the present invention obtains the original image frame of the target video and the corresponding original image frame sequence; performs a first conversion process on the original image frame of the target video according to the original image frame sequence of the target video, and determines the common chromaticity value parameters of adjacent pixels in the pixel array of the corresponding fused image frame; performs a second conversion process on the first conversion process result of the original image frame of the target video based on the common chromaticity value parameters of the adjacent pixels to form a fused image frame, wherein the fused image frame carries transparent channel information that matches the original image frame of the target video; performs video encoding process on the fused image frame according to the original image frame sequence to form corresponding video stream information to be stored. Therefore, since the video stream information to be stored is used as the carrier of the encoding result, compared with the method of using PNG sequence for transparent animation playback, it can not only effectively reduce the storage space required for the animation, but also shorten the decoding time, improve the fluency of user use, and thus effectively improve the user experience.
