Embodiment example

[0074] Wasu Cloud broadband business, parallel transcoding system business system, the overall process of transcoding system is as follows:

[0075] Such as Figure 4 As shown, when an end user accesses a web page or a web disk server through a terminal, the web page and web disk server will search the database by judging the end user terminal. If it contains the information requested by the user, it means that the current multimedia server contains the user The multimedia format supported by the terminal will feed back the corresponding multimedia server information to the user terminal, and the user terminal will go to the corresponding multimedia server to watch the video; if there is no video format supported by the user terminal, the webpage and network disk server send a transcoding request For the cloud transcoding system, when the cloud transcoding interface receives the transcoding request sent by the webpage or network disk server, it will analyze the transcoding reques...

Abstract

The invention discloses a video distributed coding format converting method which mainly comprises the following steps: slicing the original video, slicing a complete, big and long-duration video into several small videos, and converting the video code of the small videos to ensure that every piece of the video is an independent video sub-block, the smaller the video blocking is, the less elapsed time the code converting needs, thus the real-time property can be ensured; because the consumption on the computer resource is very high in code conversion, for reducing the characteristic of high consumption of the computer resource, the sliced video is sent to the resource idle code converting server to convert the code, therefore, not only is the code converting efficiency improved, but also the load of a single computer is reduced.

Description

Technical field [0001] The invention relates to a video distributed conversion coding format method. Background technique [0002] At present, in the field of video coding and decoding technology, it is possible to decode and encode videos locally (ie, video code conversion). Supports video encoding conversion from a certain part of the video to a certain segment, but only locally. Video encoding conversion adopts ffmpeg, and the relevant link address is http: / / ffmpeg.org / ffmpeg.html. At present, the video adopts ffmpeg technology as the basis, and three formats are specially converted for video encoding, namely h263, h264, mpeg4, and three The video format is currently existing video format. [0003] MPEG4 / H264 format reference standard document [0004] ISO-IEC-14496Part 1:Systems [0005] ISO-IEC-14496Part 2: Visual [0006] ISO-IEC-14496Part 3: Audio [0007] ISO-IEC-14496Part 4: Conform ance testing [0008] ISO-IEC-14496Part 5: Reference software [0009] ISO-IEC-14496Part 6: Del...
