Referring to fig. 3, which is a schematic diagram of an overall architecture of the software director system provided in this embodiment, the director system of this scheme mainly includes the following modules in terms of architecture design:
1) UI (user interface): the method comprises the steps of interface main frame, interactive setting and command sending;
2) login: logging in a protocol of YY mainly for uploading channel data;
3) CommandLogic: a command distribution logic layer;
4) input: audio and video acquisition, file decoding and local area network input;
5) engine: synthesizing a plurality of paths of pictures, responding to user scene editing and managing scenes;
6) output: previewing, uploading and recording.
Specifically, the director system of the scheme takes audio and video data as drive, can be regarded as Input data, is synthesized by the Engine and finally Output, and previews, uploads and records through the Output. The Input in fig. 3, which is specifically used for capturing or reading data, may be conveniently read by other modules. For example, different scenes can read data of the same scene at the same time; the main pair is as follows: the camera and the microphone collect signals (Camera Capture/Audio Capure/NetWorkCapture), read video files (VIDeoReader), read still pictures (ImageReader), and render Flash and Gif files (Shockwave Flash off-screen rendering). And encapsulates the signals collected by the Input by the Object, which is convenient for operation and management (VideoObject/ImageObject/TextObject).
The Engine in fig. 3 includes multiple scenes for managing and editing the Scene, such as setting size/location/zOrder of Object; scene manages a plurality of objects. And the scene Mgr is used for selecting and switching scenes. And the RunLoop is used for timing sampling and synthesizing output. The RunLoop collects data from each Object in Scene to synthesize a frame of data; the RunLoop can also collect data from different scenes at the same time, and synthesize a switching animation. And the Command logic is used for receiving the command and executing corresponding logic. The Output in fig. 3 is used to execute operations such as frame data local interface preview (Render), frame data upload to svr (upload), frame data recording and saving to disk (decoder), and the like.
Referring to fig. 4, which is a schematic diagram of a picture synthesis flow provided in this embodiment, first, a signal source needs to be added to different scenes in a director, and a Capture/Reader is started; the Capture/Reader module stores the original data into respective caches: raw Data; if the attribute of the signal source is set, recording the size, location, zorder (hierarchy in the interface) of the source; the RunLoop loop in the Engine may be a thread or a timer, and samples are performed at regular time intervals according to a set frame rate. In a single cycle, all signal sources contained in the current scene are traversed, and Raw Data and attribute values are fetched from the cache of each signal source. Zooming according to the size of the source, determining the drawing position according to the location of the source, determining the hierarchical relation of each source according to the zOrder of the source, and sequentially synthesizing each source picture from the bottom layer to the top layer; completing one circulation, namely completing original drawing of a frame of picture to obtain frame data; and informing a renderer to preview, uploading channel data by the Upload, and encoding and storing the channel data in a hard disk by the decoder.
Referring to fig. 5, a schematic view of a scene editing process provided in this embodiment is shown; in this scheme, taking the position of editing "source" as an example: the director clicks and moves the mouse in the picture in order to adjust the position of the source; the interface converts WM _ LBUTTONDOWN into a command, and sends the command to CommandLogic through CmdSender; after receiving the command, the Command logic analyzes the command and then processes the command by the Engine, and the Engine judges whether a certain 'source' is selected by the command or not; the interface continuously converts WM _ MOUSEMOVE into a command, transmits the new position of the source to the Engine, and the Engine can update the position of the selected source by combining the result of HitTest; the logic of RunLoop is synthesized with the above picture. Since the position of the selected "source" is changed, the position of the "source" screen in the newly synthesized screen is changed accordingly, that is, an editing operation is completed.
In conclusion, the software broadcasting guide system in the scheme is easy to operate, so that the main broadcasting is concentrated on the performance, and the broadcasting guide is concentrated on field control and video production; hardware configuration with high cost performance can be selected, and a studio is built by multiple cameras, multiple microphones, sound control, lamplight and the like and recommended to a user; in addition, the scheme supports real-time monitoring of multi-path audio and video pictures; the method supports the addition of multiple paths of audio and video in the same scene, the synthesis of the video and picture text materials, the scene switching of animation special effects and the uploading of scene pictures to a YY channel for live broadcast; and recording and playing back the pictures. The scheme can also support the microphone to reduce noise, for example, the noise is reduced when the sound source is more and the noise is more aiming at the field environment. A channel to be live video may also be selected.
In practical applications, for example: when a company holds a large online live conference and invites a star to hold online live show activities, after being supported by a director system, the director can show any video signal on site to audiences; the method brings more professionalism to audiences and has the video impression experience of stage impression by adding various means such as real-time interaction effect, third-party sound effect processing, sound control and the like into the star interview program; meanwhile, the station logo, the subtitle and various material guide can be matched according to own ideas.
On the basis of the perfect software function of the director system, a small-scale team organization represented by entertainment guild is popularized, which has certain requirements on the video live broadcast presentation effect and hopes to produce the live broadcast effect different from the traditional anchor personal show level. The guild organizes the guild star to perform online deduction including groups, breaks the mode that the anchor is a performer and a producer at the present stage, and leads the performer to be more concentrated in performing, for example, lyric subtitles can roll on a screen in real time in the singing process of the performer; after a cold joke passes by a plurality of people, the picture is frozen and always appears to fly through the crow; the interest and the appreciation of the whole program are greatly increased, and a more professional video live broadcast effect is brought to audiences. And gradually draw the grades with competitors.
The embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention.
