C++实现显示MP3文件信息的方法_C 语言

本文实例讲述了C++实现显示MP3文件信息的方法。分享给大家供大家参考。具体实现方法如下：

/**
 * This is small example how to use libZPlay library to play files.
 * This example is using OpenFile functions to open disk files and play.

#define WIN32_LEAN_AND_MEAN
#include <windows.h>
#include <olectl.h>
#include <ole2.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>

#include "../include/libzplay.h"
using namespace libZPlay;
ZPlay* player;
int __stdcall CallbackFunc(void* instance, void *user_data, TCallbackMessage message, unsigned int param1, unsigned int param2);
int main(int argc, char **argv)
{
  // clear screen
  system("CLS");
  // create class instance
  player = CreateZPlay();
  // chek if we have class instance
  if(player == 0)
  {
    printf("Error: Can't create class instance !nPress key to exit.n");
    getch();
    return 0;
  }
  // get library version
  int ver = player->GetVersion();
  // check if we have version 2.00 and above
  if(ver < 200)
  {
    printf("Error: Need library version 2.00 and above !nPress key to exit.\r\n");
    getch();
    player->Release();
    return 0;
  }
  // display version info
  printf("libZPlay v.%i.%02i\r\n\r\n", ver / 100, ver % 100);
  if(argc > 1)
  {
    TID3InfoEx id3_info;
    if(player->LoadFileID3Ex(argv[1], sfAutodetect, &id3_info, 1)) // loading ID3v2
    {

      // draw picture on desktop window
      player->DrawBitmapToHWND(NULL, 0, 0, 0, 0, id3_info.Picture.hBitmap);
    }
    else
    {
      printf("No ID3 data\r\n\r\n");
    }
   }
   else
   {
   // no filename in argument
    player->Release(); // delete ZPlay class
    char *end = strrchr(argv[0], '\');
    if(end && *(end + 1) != 0)
      end++;
    else
      end = argv[0];
    printf("Usage: %s filename\r\n\r\nPress key to exit\r\n", end);
    getch();
    return 0;
   }
  getch();
}
