最近看來是跟聲音干上了啊!
音頻轉換的第二種方法,這種方法相對第一種來說,要簡單的多!
首先,你得下載個“ffmpeg.exe” 插件,然後把它放到你的項目中,如下圖:
程序中會調用該文件,以助於轉換音頻格式!
上代碼:
using System; using System.Threading; using System.IO; using System.Diagnostics; using System.Security; public partial class cowala_201512Chritmas_amrtest : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { changedPlay.Visible = false; } } protected void Ffmpeg_Click(object sender, EventArgs e) { if (AmrFileUp.HasFile) { string key = AmrFileUp.FileName; string savepath = Server.MapPath("~/upload/amr/") + key; AmrFileUp.SaveAs(savepath); string mp3SavePth = Server.MapPath("~/upload/mp3/") + key.Split('.')[0].ToString() + ".mp3"; if (!string.IsNullOrEmpty(ConvertToMp3(savepath, mp3SavePth))) { changedPlay.Visible = true; changedPlay.Attributes.Add("src", "upload/mp3/" + key.Split('.')[0].ToString() + ".mp3"); Response.Write("<script>alert('轉換成功!');</script>"); } } } public string ConvertToMp3(string pathBefore, string pathLater) { string c = Server.MapPath("/ffmpeg/") + @"ffmpeg.exe -i " + pathBefore + " " + pathLater; string str = RunCmd(c); return str; } /// <summary> /// 執行Cmd命令 /// </summary> private string RunCmd(string c) { try { ProcessStartInfo info = new ProcessStartInfo("cmd.exe"); info.RedirectStandardOutput = false; info.UseShellExecute = false; Process p = Process.Start(info); p.StartInfo.UseShellExecute = false; p.StartInfo.RedirectStandardInput = true; p.StartInfo.RedirectStandardOutput = true; p.StartInfo.RedirectStandardError = true; p.Start(); p.StandardInput.WriteLine(c); p.StandardInput.AutoFlush = true; Thread.Sleep(1000); p.StandardInput.WriteLine("exit"); p.WaitForExit(); string outStr = p.StandardOutput.ReadToEnd(); p.Close(); return outStr; } catch (Exception ex) { return "error" + ex.Message; } } }
接著來張效果圖:
好了,就這麼簡單,不要不敢不相信你的眼睛,其實就是這麼簡單!
最後,來個問題:你們解完手後,擦時,習慣用左手還是右手?
