Technical Field

Background
In order to improve the storage and transmission efficiency of video, a common method is to compress video data, and the compression process involves encoding video images. Because the content of continuous multi-frame images in the video images has similarity, the video image sequence can be coded by an intra-frame prediction technology and an inter-frame prediction technology, and the video compression efficiency can be greatly improved.
In the related technology, an encoder first performs preprocessing on an input video image sequence, and performs intra-frame prediction coding and inter-frame prediction coding on coding blocks divided in each frame of image after the preprocessing is completed. When performing inter-frame prediction coding, selection of multiple inter modes is usually involved to perform coding using a type of inter mode with the least coding loss. The decision process for different inter modes tends to have a large impact on the efficiency of the encoder. For example, when an encoder performs inter-frame prediction encoding with adaptive motion vector accuracy and advanced motion vector prediction, a large number of operations such as motion estimation, motion compensation, cost calculation, transformation, and quantization processing need to be performed, which significantly increases the encoding complexity and encoding time of the encoder and requires reasonable skipping.

Fig. 1 is a flowchart of a video encoding control method provided in an embodiment of the present invention, which may be implemented by a computing device related to video encoding, such as a server, an intelligent terminal, a notebook, a tablet computer, and the like, and specifically includes the following steps:
step S101, obtaining the intra-frame preprocessing cost and the inter-frame preprocessing cost of the current coding block.
In one embodiment, in encoding video data, the encoding of each frame image is performed for a sequence of input video image frames. Optionally, in the encoding process, the video image frame is first preprocessed, where the preprocessing includes downsampling the video image frame and dividing the video image frame into coding blocks of a preset size, for example, dividing the video image frame into a plurality of coding blocks of 8 × 8 pixel area size. Video encoding, such as inter-prediction encoding or intra-prediction encoding, is performed for each divided encoding block.
In one embodiment, a determination is made as to whether to skip an inter prediction mode for a currently selected coding block, and whether to skip the inter prediction mode or not based on the determination result. In the judgment process, firstly, the intra-frame preprocessing cost and the inter-frame preprocessing cost of the current coding block are obtained. The intra-frame preprocessing cost and the inter-frame preprocessing cost may be calculated and generated in a preprocessing process of an encoder, and are respectively used for representing cost loss conditions when intra-frame prediction encoding and inter-frame prediction encoding of an image are performed, where the higher the cost loss is, the greater the distortion degree when the image is encoded is, and the lower the encoding efficiency is. Conversely, the lower the cost loss, the smaller the degree of distortion in image encoding, and the higher the encoding efficiency.
In an embodiment, for a current coding block, if the obtained intra-frame preprocessing cost and inter-frame preprocessing cost are the intra-frame preprocessing cost and inter-frame preprocessing cost of each sub-coding block included therein, the intra-frame preprocessing cost and the inter-frame preprocessing cost of each internally included sub-coding block are respectively summed to obtain the intra-frame preprocessing cost and the inter-frame preprocessing cost of the current coding block.
And step S102, when the interframe preprocessing cost is larger than the intraframe preprocessing cost, determining an adjacent coding block associated with the current coding block according to the position of the current coding block.
In one embodiment, after the intra-frame preprocessing cost and the inter-frame preprocessing cost of the current coding block are obtained, whether a step of determining an adjacent coding block associated with the current coding block according to the position of the current coding block is further triggered is judged based on the intra-frame preprocessing cost and the inter-frame preprocessing cost. If the inter-frame preprocessing cost of the current coding block is greater than the intra-frame preprocessing cost, judging that the triggering condition is met, namely further determining an adjacent coding block associated with the current coding block according to the position of the current coding block.
In one embodiment, the judgment condition that the inter-frame preprocessing cost is greater than the intra-frame preprocessing cost may be: and the difference value of the interframe preprocessing cost and the intraframe preprocessing cost is greater than a preset value. Illustratively, by using preInterCost to represent inter-frame preprocessing cost, preInterCost to represent intra-frame preprocessing cost, and the preset value is denoted as H, the determination condition may be represented as: preInterCost > preincast + H. Illustratively, the inter-frame preprocessing cost and the intra-frame preprocessing cost are different in different coding standards or results calculated based on different processing algorithms, and taking the value range of the inter-frame preprocessing cost and the intra-frame preprocessing cost as 0 to 1000 as an example, the preset value H is illustratively 300.
In one embodiment, when encoding a video frame image, a frame image is divided into a plurality of encoding blocks of the same size, for example, into a plurality of pixel regions of 16 × 16 size, each pixel region of 16 × 16 size is an encoding block, and the encoding blocks are adjacent in sequence. For the current coding block, adjacent coding blocks are respectively a coding block positioned above the current coding block, a coding block positioned below the current coding block, a coding block positioned on the left side and a coding block positioned on the right side. And determining the coding block which has finished coding as the adjacent coding block associated with the current coding block in the adjacent coding blocks of the current coding block according to the coding sequence of the coding blocks. For example, the coding block above and the coding block on the left side of the current coding block are adjacent to the current coding block and are already coded, and then the coding block above and the coding block on the left side of the current coding block are determined as the adjacent coding block associated with the current coding block.
Step S103, determining whether to skip the inter-frame prediction mode of the current coding block according to the coding information of the adjacent coding blocks, and skipping the inter-frame prediction mode of the current coding block in response to the judgment result of skipping the inter-frame prediction mode of the current coding block.
In one embodiment, after determining the adjacent coding block associated with the current coding block, whether to skip the inter prediction mode of the current coding block is determined based on the coding information of the adjacent coding block. The coding information of adjacent coding blocks records the coding condition used by the adjacent coding blocks, such as whether the adjacent coding blocks are coded by using an intra-frame prediction mode or an inter-frame prediction mode. Optionally, if the adjacent coding blocks are all encoded by using the intra-frame prediction mode, the inter-frame prediction mode of the current coding block is skipped, that is, the inter-frame prediction mode is processed.
According to the scheme, the intra-frame preprocessing cost and the inter-frame preprocessing cost of the current coding block are obtained, when the intra-frame preprocessing cost is larger than the intra-frame preprocessing cost, the adjacent coding block associated with the current coding block is determined according to the position of the current coding block, whether the inter-frame prediction mode of the current coding block is skipped is determined according to the coding condition of the adjacent coding block, and the inter-frame prediction mode of the current coding block is skipped in response to the judgment result of the inter-frame prediction mode of the skipped current coding block, so that the video coding efficiency is guaranteed, the inter-frame prediction mode is reasonably skipped, the coding efficiency of a coder is improved, and the processing time consumption of the coder is remarkably reduced.
Fig. 2 is a flowchart of another video coding control method according to an embodiment of the present invention, which shows a specific method for determining an adjacent coding block associated with a current coding block according to a position of the current coding block, as shown in fig. 2, including:
step S201, obtaining an intra-frame preprocessing cost and an inter-frame preprocessing cost of a current coding block.
Step S202, when the inter-frame preprocessing cost is larger than the intra-frame preprocessing cost, determining an adjacent coding block associated with the current coding block according to the position of the current coding block and the coding sequence of each coding block.
In one embodiment, after the division of the coding blocks is performed, the coding is sequentially performed according to the set coding order. When the adjacent coding block associated with the current coding block is determined, the adjacent coding block associated with the current coding block is determined according to the position of the current coding block and the coding sequence of each coding block. Specifically, as shown in fig. 3, fig. 3 is a schematic diagram of determining adjacent coding blocks associated with a current coding block according to an embodiment of the present invention, an exemplary image is divided into 16 coding blocks with 4 rows and 4 columns, and a coding order of each coding block includes sequentially coding the coding blocks from top to bottom row by row and from left to right, that is, sequentially coding the coding blocks from 1 to 16 according to sequence numbers of each coding block in fig. 3. Of course, other sequences may be used for encoding, and the specific encoding sequence of each encoding block is not limited. In another embodiment, the coding sequence of each coding block may also be that the coding is performed sequentially from top to bottom and from right to left line by line according to the position of each coding block, and then according to the coding sequence, it is determined that the adjacent coding blocks associated with the current coding block are the adjacent upper coding block and the adjacent right coding block. In another embodiment, the coding sequence of each coding block may also be that the coding is performed sequentially from left to right and from top to bottom according to the position of each coding block, and then according to the coding sequence, it is determined that the adjacent coding block associated with the current coding block is the same as the case of performing coding sequentially from left to right and from row to row, and the adjacent upper coding block and the adjacent left coding block of the current coding block are determined as the associated adjacent coding blocks. Similarly, the coding sequence of each coding block may also be that the coding is performed sequentially from right to left and from top to bottom according to the position of each coding block, and then it is determined that the adjacent coding block associated with the current coding block is the same as the case of performing the coding sequentially from row to row and from right to left according to the coding sequence, and the adjacent upper coding block and the adjacent right coding block of the current coding block are determined as the associated adjacent coding blocks.
Taking fig. 3 as an example, assuming that the current coding block is coding block 6, and the coding blocks adjacent to coding block 6 are coding blocks 2, 5, 7 and 10, according to the sequence that each coding block sequentially performs coding from top to bottom row by row and from left to right, the adjacent upper coding block 2 and the adjacent left coding block 5 of the current coding block are selected to be determined as the adjacent coding block associated with the current coding block. Taking the coding block 2 as an example, the coding blocks 1, 3 and 6 adjacent to each other are known to be sequentially coded from left to right line by line according to the sequence in which each coding block is sequentially coded from left to right, and only the coding block 1 on the adjacent left side exists and the coding block above the adjacent left side does not exist.
Step S203, determining whether to skip the inter-frame prediction mode of the current coding block according to the coding information of the adjacent coding block, and skipping the inter-frame prediction mode of the current coding block in response to the judgment result of skipping the inter-frame prediction mode of the current coding block.
As can be seen from the above, by obtaining the intra-frame preprocessing cost and the inter-frame preprocessing cost of the current coding block, when the inter-frame preprocessing cost is greater than the intra-frame preprocessing cost, determining adjacent coding blocks related to the current coding block according to the position of the current coding block and the coding sequence of each coding block, determining whether to skip the inter-frame prediction mode of the current coding block according to the coding condition of the adjacent coding blocks, skipping the inter-frame prediction mode of the current coding block in response to the judgment result of skipping the inter-frame prediction mode of the current coding block, that is, when determining whether a current coding block skips an inter prediction mode, a decision is made with reference to coding information of an adjacent coding block, thereby achieving, and reasonably skipping the inter-frame prediction mode, improving the coding efficiency of the coder and obviously reducing the time consumption of the coder.
Fig. 4 is a flowchart of another video coding control method according to an embodiment of the present invention, which provides a specific manner for determining whether to skip an inter prediction mode of a current coding block according to coding information of adjacent coding blocks, and as shown in fig. 4, the specific manner includes:
step S301, acquiring the intra-frame preprocessing cost and the inter-frame preprocessing cost of the current coding block.
Step S302, when the interframe preprocessing cost is larger than the intraframe preprocessing cost, determining an adjacent coding block associated with the current coding block according to the position of the current coding block.
Step S303, determining whether to skip the inter-frame prediction mode of the current coding block according to the condition of whether the adjacent coding block exists and the coding mode of the adjacent coding block, and skipping the inter-frame prediction mode of the current coding block in response to the judgment result of skipping the inter-frame prediction mode of the current coding block.
In one embodiment, the encoding mode of the adjacent encoding block may be determined by encoding information of the adjacent encoding block, by which the encoding mode of the adjacent encoding block is determined, the encoding mode including an inter prediction mode and an intra prediction mode. Optionally, whether to skip the inter prediction mode of the current coding block is determined according to the presence or absence of the adjacent coding block and the coding mode of the adjacent coding block. Specifically, the set judgment condition may be: and if the adjacent coding blocks do not exist or the coding modes of the adjacent coding blocks are all intra-frame prediction modes, skipping the inter-frame prediction mode of the current coding block and directly carrying out prediction coding of the intra-frame prediction mode.
From the above, by obtaining the intra-frame preprocessing cost and the inter-frame preprocessing cost of the current coding block, when the inter-frame preprocessing cost is greater than the intra-frame preprocessing cost, determining the adjacent coding block associated with the current coding block according to the position of the current coding block, then determining whether to skip the inter-frame prediction mode of the current coding block according to the existence condition of the adjacent coding block and the coding mode of the adjacent coding block, skipping the inter-frame prediction mode of the current coding block in response to the judgment result of the inter-frame prediction mode of skipping the current coding block, and skipping the inter-frame prediction mode of the current coding block by referring to the specific condition of the adjacent coding block of the current coding block if the adjacent coding blocks are the intra-frame prediction modes, thereby realizing reasonable skipping of the inter-frame prediction mode while ensuring the video coding efficiency and improving the coding efficiency of the encoder, the encoder processing time is significantly reduced.
Fig. 5 is a flowchart of another video coding control method according to an embodiment of the present invention, where when obtaining an intra-frame preprocessing cost and an inter-frame preprocessing cost of a current coding block, the method further includes: setting an inter-frame prediction mode of a current coding block to be in an unavailable state; correspondingly, in response to the result of determining that the inter prediction mode of the current coding block is not skipped, setting the inter prediction mode of the current coding block to be in an available state, and performing prediction coding of the intra prediction mode of the current coding block, as shown in fig. 5, specifically including:
step S401, obtaining the intra-frame preprocessing cost and the inter-frame preprocessing cost of the current coding block, and setting the inter-frame prediction mode of the current coding block to be in an unavailable state.
In one embodiment, the skip flag is set to characterize the skip inter prediction mode of the current coding block, for example, the skip flag is set to false, which indicates that the inter prediction mode of the current coding block is unavailable. Illustratively, when determining whether to skip the inter-frame prediction mode for each coding block, the skip flag is initialized to false in the process of obtaining the intra-frame preprocessing cost and the inter-frame preprocessing cost.
Step S402, when the inter-frame preprocessing cost is larger than the intra-frame preprocessing cost, determining an adjacent coding block associated with the current coding block according to the position of the current coding block, and determining whether to skip the inter-frame prediction mode of the current coding block according to the coding information of the adjacent coding block.
And S403, responding to the judgment result of skipping the inter-frame prediction mode of the current coding block, and skipping the inter-frame prediction mode of the current coding block.
Step S404, responding to the judgment result of the inter-frame prediction mode of the current coding block, setting the inter-frame prediction mode of the current coding block to be in an available state, and performing prediction coding of the inter-frame prediction mode of the current coding block.
In one embodiment, if it is determined that the inter prediction mode is not skipped, the inter prediction mode of the current coding block is set to be available, and the intra prediction mode of the current coding block is predicted.
It can be known from the above that, by obtaining the intra-frame preprocessing cost and the inter-frame preprocessing cost of the current coding block, setting the inter-frame prediction mode of the current coding block to be in an unavailable state, when the inter-frame preprocessing cost is greater than the intra-frame preprocessing cost, determining the adjacent coding block associated with the current coding block according to the position of the current coding block, then determining whether to skip the inter-frame prediction mode of the current coding block according to the coding condition of the adjacent coding block, skipping the inter-frame prediction mode of the current coding block in response to the determination result of the inter-frame prediction mode of the current coding block, setting the inter-frame prediction mode of the current coding block to be in an available state in response to the determination result of the inter-frame prediction mode of the current coding block, and performing the prediction coding of the inter-frame prediction mode of the current coding block, thereby making a determination whether to skip the inter-frame prediction mode of the current coding block according to the coding condition of the adjacent coding block of the current coding block, if the skipping condition is met, skipping is carried out, and if the skipping condition is not met, skipping is not carried out, so that reasonable skipping of the inter-frame prediction mode is realized while video coding efficiency is guaranteed, the coding efficiency of the coder is improved, and the time consumption of the coder in processing is obviously reduced.
