RDVECore features Overview

RDVECore is a uI-free, highly abstract API video editing SDK launched by Rui Rui. It supports the following functions:

1.1 Rich editing functions

RDVECore contains a wealth of basic functions, for the editing of video, pictures, music has a variety of processing methods, and can be combined according to the actual business needs, all processing can be accurate to the millisecond level, to achieve the most professional requirements, the main functions are as follows: The RDVEUISDK itself provides a variety of filter effects for developers to choose from, while allowing users to extend the filters according to their own needs. According to the Principle of principle, subtitles can be displayed at a certain location during a certain period of time. Soundtrack and dubbing can be added during a specified period of time. Support dubbing, soundtrack and video audio ratio adjustment; Add more music to the local system according to the Bill. Intercept and split video at the millisecond level. Supports quick preview, clip, and segmentation, and adjusts the playing speed of a video by playing it either fast or slow, supporting multiple transitions. Extended Settings such as random transition and specified transition duration are supported. Other editing functions support multiple proportional clipping. Support 90, 180, 270 degree rotation video picture; Supports left and right mirroring and upper and lower mirroring. Support output ratio adjustment;

1.2 Perfect video shooting function

 real-time facial Can real-time facial skin in the process of filming, brighten and whiten skin effect, achieve facial beautification, at the same time, the adjustment of the support degree of beautification  face stickers/hang support face recognition and stickers/widgets display  shooting freedom definition  RDVECore during filming, can according to the specific record demand, for liberalisation of the Settings, Have better and excellent shooting and recording effect. Multiple shooting A video can be divided into multiple shooting sessions. The cameras can switch freely before and after camera switching, and there is no lag in the middle. Multiple ratios 1:1, 9:16 and 16:9 zoom recording and focusing. Filters can also be added in real time, and the RDVEUISDK itself provides a rich selection of filters for developers to choose from, while users can also extend filters to suit their own needs.  Save the current camera screen to the RDVECore architecture diagram:

2.1 Operating Environment

The SDK supports iOS7.0 and later devices, compatible with iPhone, iPad, and iPod touch

2.2 Registering and applying for AppKey and APPSecret 2.2.1 Open www.rdsdk.com/ and choose login or registration on the homepage of Ruizun official website. New users register first and old users log in directly. 
 2.2.2 After login, enter the video cloud management, click “+ Add”, fill in the name you should use, and click “Submit” to complete the application creation. 
 2.2.3 After creating an application, the system automatically jumps to the personal center page and obtains the AppKey and AppSecret of the application.

2.3 Downloading and Importing the SDK

2.3.1 Add static library Librdvcore. a and header file

Add RDVECore 2.3.2. Bundle

2.3.3 Project Setup Scenography TARGETS Deployment Info is selected only for Portrait and unlandscapeleft:
