# FFmpegDemo
A video and audio editor library based on ffmpeg 6.0 api;  
What does it can do?  
    1: Media splis  
    2: Media merge  
    3: Media format convert  
    4: Audio mix  
    5: Recording data from media stream, and generate media file  
    6: Detach video or audio from media file  
    7: Filter video and audio, user can inherit IFilter class and implement what need to do  
    8: Encoding PCM data, and generate media file  

Media files include audio and video files, RTSP and other audio and video streams.  
It also supports hardware acceleration.  

This project is built on visual studio 2022, and the aveditor project is a static library.  
This project is base on FFmpeg 6.0. and SDL 2.30.7

///////////////////////////////////////////////////////////////////////////////////////////  
AVStudio  
    A dll project that implements all functions.
 
Modules:  
    Api: Simple encapsulation of FFmpeg API  
    SDL: Sdl api that support playing  
    IO: Input and output of AVFrame or AVPacket  
    Core: User interface module  
    Filter: Video and audio filter, User can inherit IFilter class to define new filter.  

///////////////////////////////////////////////////////////////////////////////////////////  
Class Description:  
    CEditor: User interface, it will run the tasks in thread. And manage the IO handle and setting module.  
        When open an input file, one CFactory object will be created. Caller can open multiple input file   
    CFactory: Do demuxing, decoding, converting, filtering, encoding. The final data is output from the IO handle.  
        There is a input context object, a pointer points to output context, an IO handle pointer in CFactory.  
    FWorkShop: Input/output context management, including:  
        create codec context, stream.  
        set Filter.   
        manage video/audio pts.  
        manage clipping of input context  
        and so on.  
    FLatheParts: Manage the object pointers that required for file demultiplexing, encoding and decoding, conversion, filtering, and other operations.  
    FSetting: Settings about hardware acceleration on codec
