Embodiment 1

[0033] like figure 1 As shown, it is a method for adaptively specifying transcoding described in Embodiment 1 of this application, which includes:

[0034] Step 101, intercepting the data stream formed by video resource transmission to obtain the intercepted data stream.

[0035] In step 101, the intercepted data stream is a data stream with a first label.

[0036] Specifically, when a video website performs a video transcoding task, it will transfer the video source stored in the video source server for transcoding processing. Under normal circumstances, the video website uses a cloud transcoding system, and users from all over the world can transfer video resources to After uploading to the corresponding source server, after transcoding, users in other regions can access the video website to watch or download corresponding video resources through computer terminals, mobile terminals or TV terminals.

[0037] When video resources are transmitted over the network, it is not ...

Embodiment 2

[0047] like figure 2 As shown, it is a method for adaptively specifying transcoding described in Embodiment 2 of this application, which includes:

[0048] Step 201, intercepting the data stream formed by video resource transmission to obtain the intercepted data stream.

[0049] In step 201, the intercepted data stream is a data stream with a first label.

[0050] In this embodiment, when video resources are transmitted over the network, instead of the entire video file or video source being transmitted cooperatively, the video file or video source is formed into a data sequence in a certain order, that is, transmitted in the form of a data stream. During transmission, the data streams of the video resource all have a first label, and the data stream with the first label corresponds to the starting playback position of the video resource, and at the same time, the data stream with the first label contains the information tag of the video resource, that is, after the video ...

Embodiment 3

[0075] The specific application of the method for adaptively specifying transcoding is described in detail below:

[0076] The background is: there are 3 kinds of video resources (taking film sources as an example) that will be transcoded, namely film sources A, B and C, of ​​which:

[0077] The resolution of source A is 848*480, and its bit rate is 550kbps;

[0078] The resolution of source B is 1280*720, and its code rate is 960kbps;

[0079] The resolution of source C is 1280*720, and its code rate is 1650kbps.

[0080] The above three sources will be played on TV terminals, mobile terminals and computer terminals, and all need to be transcoded into ".flv" and ".mp4" formats.

[0081] The specific steps are:

[0082] First, intercept the data streams formed by the transmission of video resources (sources A, B, and C) to obtain the intercepted data streams.

[0083] Among them, for the transmission of the film source, the user may upload the film source to the correspond...

Abstract

The invention discloses a method and system for self-adaptive appointed transcoding. The method comprises the following steps: intercepting a data stream formed in video resource transmission so as to acquire an intercepted data stream, determining the resolution and code rate of the video resource according to the intercepted data stream, acquiring a target code stream matched with the video resource according to preset transcoding rules, the resolution and the code rate, and transcoding. By adopting the method and the system, the problem that transcoding can not be performed according to the corresponding target code stream matched with the video source resolution self-adaption during transcoding process is solved.

Description

technical field [0001] The present application relates to the field of video transcoding, and more specifically, relates to a method and system for adaptive specified transcoding. Background technique [0002] In the existing technology, with the rapid development of information technology, the form of expression and transmission of information has changed: from traditional text (such as: books, newspapers) and audio (such as: broadcast), and then transformed into a vivid Expressive and more informative video approach. Today's TV and the Internet present and share rich and comprehensive resources such as various film and television programs, news, advertisements, chats, education, and games in the form of video, so that video has become an irreplaceable and important tool for people to learn, socialize, and entertain. Way. [0003] For different video resources, they have different video formats, and not all video formats are suitable for TV or network transmission. Videos...
