Merge Video Project Source Code

This merge video project aims to merge multiple videos with ".mp4" file using H264 codec.

Libraries:

• wxWidgets (C++): For developing friendly GUI
• ffmpeg (C): For processing media file and read metadata from media file

Tools (optional - depending on your usage):

CodeBlock - Tutorial for linking with wxWidgets MinGW (Windows version and MSYS2 version) MSYS2

Operating System:

I use Windows as the main environment. I haven't tested Linux yet.

Source code tree simple view:

Note that I do not upload the ffmpeg and wxWidgets source code, so you have to find them)

• merge_video_project/
  • bin/
    • ffmpeg.exe (You can install FFmpeg executable file here)
  • lib/
    • ffmpeg/ (ffmpeg compiled source code, you can install FFmpeg source code here)
  • resource/ (Images file)
  • src/ (Source file for merge video project)
• wxWidgets/ (You can install wxWidgets for C++ here)

Compiling Guide:

1. Compiles wxWidgets (You can use MinGW compiler with MSCVRT environment or use Visual Studio)

2. Compiles FFmpeg (If you use MinGW, you should install MSYS2 to configure FFmpeg source code and install them. Note that you should use MINGW32 or MINGW64 of MSYS2 to match the MSCVRT environment with wxWidgets. Using UCRT might not compile)

3. (Optional if linking failed while compiling) Installs zlib source code, libiconv source code and uses MSYS2 to configure and compile. Then copies libraries (usually ".dll", ".o", ".a" files) to your compiler. (These libraries are not available in Windows and these are required from FFmpeg library)

4. Compiles all sources code from src. Notes that you should have linked all the required libraries and includes files from both wxWidgets and FFmpeg libraries.
