Abstract
The invention discloses a video encoding method and relates to the field of encoding. The video encoding method is invented for solving the problem that large storage space is occupied for video storage in the prior art and transmission efficiency is low during direct video transmission. According to the technical scheme, the video encoding method comprises the steps that S10, a video encoding indication input by a user is received; S20, a target encoding mode is selected from a preset encoding library according to the video encoding indication; S30, adopting the target encoding mode to conduct encoding on videos corresponding to the video encoding indication to obtain encoded videos. The video encoding method can be applied to the fields of video conferences, video electronic commerce, online government administration, online shopping, online schools, remote telemedicine, chat online, video consulting and the like.
Description
Technical field
The present invention relates to coding field, particularly relate to a kind of method for video coding.
Background technology
At present, video technique is applied in the fields such as video conferencing, visible electronic commercial affairs, online government affairs, shopping online, online school, tele-medicine, online chat and visual consulting widely.But, because the data volume of video is comparatively large, during video storage, take a large amount of memory spaces, and directly transmission of video time efficiency of transmission lower.
Summary of the invention
The invention provides a kind of method for video coding, system can directly be stored or video after transfer encoding, thus save memory space and improve video transmission efficiency.
Technical solution problem of the present invention adopts following technical scheme: a kind of method for video coding, comprising: the Video coding instruction of S10, reception user input; S20, from pre-arranged code storehouse, choose target code pattern according to the instruction of described Video coding; S30, the video adopting described target code pattern corresponding to described Video coding instruction are encoded, and obtain the video after encoding.
Optionally, pre-arranged code storehouse described in the method for video coding that the embodiment of the present invention provides, comprising: MPEG-1 coding mode, MPEG-2 coding mode, MPEG-4 coding mode, H.261 coding mode, H.262 coding mode, H.263 coding mode and one or more H.264 in coding mode.
Optionally, described in the method for video coding that provides of the embodiment of the present invention, H.263 coding mode adopts the estimation of half-pixel accuracy.
Optionally, described in the method for video coding that provides of the embodiment of the present invention, H.264 coding mode adopts the estimation of 1/4 or 1/8 pixel precision.
Optionally, described in the method for video coding that provides of the embodiment of the present invention, H.264 coding mode also adopts multi-frame prediction and/or Adaptive deblocking filter device.
Optionally, described in the method for video coding that provides of the embodiment of the present invention H.264 coding mode quantization step with 12.5% recombination rate go forward one by one.
Optionally, described in the method for video coding that provides of the embodiment of the present invention, S30 comprises: S301, be at least one macro block by Video segmentation corresponding for described Video coding instruction; S302, adopt described target code pattern to encode at least one macro block described respectively, obtain the video after encoding.
The present invention has following beneficial effect: adopt target code pattern corresponding to the Video coding instruction of user's input to encode to video, store or transmission after obtaining the video after encoding.The technical scheme that the embodiment of the present invention provides, owing to store or the video of transmission is video after coding, therefore, it is possible to save memory space improve video transmission efficiency; To solve in prior art because the data volume of video is comparatively large, during video storage, take a large amount of memory spaces, and directly transmission of video time the lower problem of efficiency of transmission.
Accompanying drawing explanation
The flow chart of the method for video coding that Fig. 1 provides for the embodiment of the present invention 1.
Embodiment
Below in conjunction with embodiment and accompanying drawing, technical scheme of the present invention is further elaborated.
Embodiment 1
As shown in Figure 1, present embodiments provide a kind of method for video coding, comprising:
Step 101, receives the Video coding instruction of user's input.
In the present embodiment, can receive the Video coding instruction that user inputs in the mode of word by step 101, also can receive by step 101 the Video coding instruction that user inputs in the mode of voice, this is not restricted.Especially, when user indicates with phonetic entry Video coding, need that identification is carried out to voice and resolve, to obtain corresponding word.
Step 102, chooses target code pattern according to Video coding instruction from pre-arranged code storehouse.
In the present embodiment, in step 102, pre-arranged code storehouse comprises: MPEG-1 coding mode, MPEG-2 coding mode, MPEG-4 coding mode, H.261 coding mode, H.262 coding mode, H.263 coding mode and one or more H.264 in coding mode.Especially, in order to improve picture quality, this H.263 coding mode adopt the estimation of half-pixel accuracy; This H.264 coding mode adopt the estimation of 1/4 or 1/8 pixel precision; In order to provide error-correcting performance better, reduce blocking artifact, this H.264 coding mode also adopt multi-frame prediction and/or Adaptive deblocking filter device; In order to improve Rate Control ability, this H.264 coding mode quantization step with 12.5% recombination rate go forward one by one.
Step 103, the video adopting this target code pattern corresponding to Video coding instruction is encoded, and obtains the video after encoding.
In the present embodiment, the process of the video after obtaining coding by step 103 can comprise: first indicate corresponding Video segmentation to be at least one macro block Video coding; Secondly adopt target code pattern to encode to this at least one macro block respectively, obtain the video after encoding.
The present invention has following beneficial effect: adopt target code pattern corresponding to the Video coding instruction of user's input to encode to video, store or transmission after obtaining the video after encoding.The technical scheme that the embodiment of the present invention provides, owing to store or the video of transmission is video after coding, therefore, it is possible to save memory space improve video transmission efficiency; To solve in prior art because the data volume of video is comparatively large, during video storage, take a large amount of memory spaces, and directly transmission of video time the lower problem of efficiency of transmission.
The sequencing of above embodiment, only for ease of describing, does not represent the quality of embodiment.
Last it is noted that above embodiment is only in order to illustrate technical scheme of the present invention, be not intended to limit; Although with reference to previous embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
