Group 62 — C Music Player (SDL2 + SDL_mixer)

Overview

Console-based music player that supports:

• Add, display, edit, delete songs
• Shuffle playlist
• Play / Pause / Resume / Next / Prev / Stop

Requirements

• SDL2
• SDL2_mixer (built with support for your audio formats, e.g., MP3/OGG/WAV)
• A C compiler (GCC/Clang or MinGW)

Build (Linux/Mac)

gcc -o music_player src/music_player.c -lSDL2 -lSDL2_mixer

If SDL is installed in a non-standard path, add -I and -L flags accordingly.

Build (Windows / MinGW)

gcc -o music_player.exe src\music_player.c -lmingw32 -lSDL2main -lSDL2 -lSDL2_mixer

Ensure SDL2 and SDL2_mixer DLLs are in the same folder as the executable or on PATH.

Run

./music_player   # or music_player.exe

Usage / Expected I/O

Program shows a numbered menu:

1. Add Song — enter Title, Artist, and file path to an audio file (e.g., C:\music\song.mp3)
2. Display Songs — prints the playlist (index, title, artist)
3. Edit Song — choose index; enter new title/artist or press Enter to skip
4. Shuffle Playlist — randomizes the order
5. Player — interactive sub-menu:
   • 1 Play: loads current index and starts playback
   • 2 Pause
   • 3 Resume
   • 4 Next: move to next index and play
   • 5 Prev: move to previous index and play
   • 6 Shuffle: randomize playlist, reset current index
   • 7 Stop: stop playback
   • 8 Back: return to main menu
6. Delete Song — remove by index
7. Exit

Expected Input: integers for menu choices and text for song info.
Expected Output: status lines like "Playing:", "Paused.", "Song deleted.", or any SDL error messages if loading fails.

Notes & Optimizations

• Current shuffle is a simple swap-based approach. For unbiased results, prefer Fisher–Yates:

  for (int i = n - 1; i > 0; --i) {
      int j = rand() % (i + 1);
      swapSongs(i, j);
  }

• Always free Mix_Music before loading a new one to avoid leaks (handled in code).
• Validate file paths exist before attempting to load (can be added with fopen check).
