Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be described clearly and completely with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, not all of the embodiments. The components of the embodiments of the present disclosure, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present disclosure, presented in the figures, is not intended to limit the scope of the claimed disclosure, but is merely representative of selected embodiments of the disclosure.

In addition, the term "at least one" herein means any one of a plurality or any combination of at least two of a plurality, for example, including at least one of A, B, C, and may mean including any one or more elements selected from the group consisting of A, B and C.
At present, methods for reducing the display duration of the first frame of the online video generally start with the speed of rendering the first frame of the video at the client and the downloading speed of the video resource, for example, the playing flow of the video player at the client can be optimized, the video frame can be quickly rendered, or the downloading node of the video resource can be optimized, so that the data transmission speed is higher. However, when the data transmission technology and the picture rendering technology are both developed to a higher degree, it is difficult to further improve the data transmission and picture rendering rates, so that the display duration of the first frame is difficult to be significantly improved.
Based on the research, the present disclosure provides an online video processing method, which can compress first image group data in an initial resource file of a target video and generate an optimized resource file containing the compressed video file, so that a storage space occupied by the first image group data in the optimized resource file is reduced, when an online video is transmitted, time consumed for transmitting the first image group data is reduced, and a client can receive data required for rendering a first frame of the video earlier, thereby shortening the display duration of the first frame.
To facilitate understanding of the present embodiment, first, an online video processing method disclosed in the embodiments of the present disclosure is described in detail, where an execution subject of the online video processing method provided in the embodiments of the present disclosure is generally a computer device with certain computing capability, and the computer device includes, for example: terminal equipment or servers or other processing devices. In some possible implementations, the online video processing method may be implemented by a processor calling computer readable instructions stored in a memory. The online video processing method provided by the embodiment of the disclosure is described below with an execution subject as a server.
Referring to fig. 1, a flowchart of an online video processing method provided in the embodiment of the present disclosure is shown, where the method includes steps S101 to S103, where:
s101: acquiring an initial resource file of a target video, and dividing the initial resource file into a first video file and a second video file; the first video file comprises first image group data in the initial resource file; the second video file comprises the image group data except the first image group data in the initial resource file.
In this step, the server may obtain an initial resource file of the target video from the database, or obtain the initial resource file through the upload interface, where the target video may be an online video, the initial resource file may be a file containing data corresponding to the target video, and may transmit the target video to the client in the form of a streaming media according to a preset online video transmission protocol, and the client may start playing the target video after receiving part of the initial resource file.
Here, the initial resource file may be in a Flash Video (FLV) format, and the FLV format file has the characteristics of small occupied space and high loading speed, is a streaming media format, and is suitable for playing an online Video.
After receiving a part of an initial resource file, a client can start to render a picture corresponding to the part, because the client usually plays from a first frame picture when playing an online video, in the video, because a large number of same pixel points exist among pictures, in order to reduce the size of the file, picture frames with repeated contents can be simplified, and the picture of the frame is simplified by utilizing the difference between the frame and a key frame, for example, the first frame picture is usually the first key frame of the whole video, namely an inner coding frame (I frame), which is a complete picture frame, each pixel point is complete data, and some subsequent frame pictures can be a forward prediction frame (P frame) and a bidirectional interpolation frame (B frame) until the next I frame, the P frame can determine the data of the pixel point according to the I frame before the frame, and the B frame needs the previous I frame and the next I frame to determine the data of the pixel point, therefore, when a client acquires a P frame or a B frame, the client can render the frame only by acquiring an I frame corresponding to the frame at the same time, and the I frame and the corresponding P frame and B frame thereof can form an image group. Therefore, the client can perform the rendering of the first frame after receiving the data corresponding to the first image group. Further, in order to reduce the display duration of the first frame, the time consumed by the client to download the first image group can be reduced.
In this step, the initial resource file may be divided into a first video file containing first image group data and a second video file containing remaining image group data except the first image group data, where the first video file and the second video file may further include Metadata, which is also called intermediary data and relay data, as data about description data (data about), mainly information about description data attribute (property), and is used to support functions such as indicating storage location, history data, resource search, file record, and the like. In video rendering, it is often necessary to utilize information in the metadata.
In one possible embodiment, the dividing the initial resource file into a first video file and a second video file includes:
intercepting first image group data from the initial resource file;
generating the first video file based on the intercepted first image group data and the first metadata of the initial resource file; and generating the second video file based on the first metadata and the remaining data in the initial resource file except the first image group data.
Referring to fig. 2, a schematic structural diagram of each file in the online video processing method provided by the embodiment of the present disclosure is shown. The initial resource file A comprises first metadata x, image group data a, image group data B, image group data C, … … and image group data h, after the first image group data a and the first metadata x are intercepted from the initial resource file A, the image group data a and the first metadata x can be spliced to obtain a first video file B, and then the remaining data of the intercepted initial resource file A, namely the image group data B, the image group data C, … … and the image group data h, are spliced with the first metadata x to obtain a second video file C, wherein the initial resource file is in an FLV format.
S102: performing video compression on the first video file to obtain a compressed video file corresponding to the first video file; the file size of the compressed video file is smaller than the first video file.
In this step, video compression can be performed by adjusting the resolution of the first video file, reducing the number of frames in the image group, or the like, and the file size of the first video file can be reduced by video compression.
In one possible implementation, video compression may be performed by:
and performing video compression on the first video file based on a preset target transcoding parameter and a preset transcoding tool to obtain the compressed video file.
The target transcoding parameter may be preset, or may be determined based on attribute information of the first video file recorded in the metadata of the first video file, for example, the target resolution in the target transcoding parameter may be determined according to a resolution of the first video file in the metadata, and whether to delete a B frame may be determined according to a frame picture type in the first video file recorded in the metadata.
After the compressed video file is generated, second metadata corresponding to the compressed video file may be generated.
Further, compression rates of respective portions in the compressed video file may be different, and specifically, the compressed video file may be obtained through the following steps:
segmenting the first video file into at least two first video subfiles;
compressing the at least two first video subfiles respectively based on at least two target transcoding parameters and the transcoding tool to obtain at least two first compressed video files;
and splicing the at least two first compressed video files into the compressed video file.
In this step, the first video file may be divided into at least two first video subfiles according to a preset division rule, each first video subfile may include at least one frame of picture, each first video subfile may be deployed with a corresponding target transcoding parameter, the first video file may be compressed by using a transcoding tool according to the corresponding target transcoding parameter, so as to obtain first compressed video files with different resolutions, and then the plurality of first compressed video files are spliced together according to a playing sequence, so as to obtain the compressed video file.
Here, the target transcoding parameters corresponding to each first video subfile may be preset according to requirements, for example, the first frame is compressed to a high-definition resolution, the second frame is compressed to a high-definition resolution, the third frame maintains the high-definition resolution, the fourth frame is compressed to a smooth resolution, and the like; the transcoding parameter may also be determined according to the corresponding position of the first video subfile in the first video file, for example, if the first video file is split into three first video subfiles, the target transcoding parameter of the first video subfile at the first playing position in the first video file may be set to a lower bitrate or resolution, so that the first playing part can be transmitted faster; the target transcoding parameters of the first video sub-file at the last playing position can be set to be higher in bitrate or resolution, and can be closer to the bitrate or resolution of the second video file than the target transcoding parameters corresponding to the first playing position; the target transcoding parameters of the first video subfiles in the middle playing position can be located between the target transcoding parameters of the two first video subfiles, so that the resolution of the compressed video file is increased in a step mode and gradually restored to the normal resolution, and the previous frame pictures can be transmitted to the client side more quickly.
Referring to fig. 2, the compressed video file D includes compressed image group data a ' and second metadata x ' corresponding to the image group data a '.
S103: and splicing the compressed video file and the second video file to obtain the optimized resource file of the target video.
In this step, the compressed video file obtained by transcoding the first video file and the second video file may be spliced, so that the compressed video file and the second video file are merged into an optimized resource file.
Here, in the case where the initial resource file is in the FLV format, the first video file, the second video file, and the optimized resource file may also be in the FLV format.
Here, the second video file may be compressed to obtain a second compressed video file, and then the compressed video file and the second compressed video subfile are spliced, so that a portion corresponding to the second video file in the optimized resource file is also compressed, thereby increasing the transmission speed of the specific frame.
Specifically, the second video file may be first divided into at least two second video subfiles; then, compressing the at least two second video subfiles to obtain at least two second compressed video files; and finally, splicing the compressed video file and the at least two second compressed video files to obtain the optimized resource file of the target video.
The second video file can be segmented and compressed according to a preset segmentation rule and a preset compression strategy, and various play modes such as gradual definition, stage definition and the like can be realized on the optimized resource file according to different requirements of application scenes.
In a possible implementation manner, the splicing the compressed video file and the second video file to obtain the optimized resource file of the target video includes:
splicing the tail part of the image group data of the compressed video file with the head part of the image group data of the second video file to obtain the optimized image group data;
merging second metadata of the compressed video file with the first metadata of the second video file to obtain the optimized metadata;
and combining the optimized image group data and the optimized metadata to obtain the optimized resource file.
As shown in fig. 2, in the optimized resource file E, the tail of the image group data a 'of the compressed video file D is connected to the image group data b in the second video file C, and the second metadata x' of the compressed video file D is merged with the first metadata x of the second video file C to obtain the optimized metadata z of the optimized resource file E.
Wherein the optimization metadata is header information of the optimized resource file. Therefore, when the client side carries out the picture rendering of the video, the client side can directly obtain the optimized metadata without searching, the picture rendering speed can be improved to a certain degree, and the display duration of the first frame is further reduced.
In order to enable the client to download the optimized resource file more quickly, after the optimized resource file is obtained, the optimized resource file can be sent to the client through the following steps:
