Converting Video file to FLV file

string video = @"D:\Projects\TestProject\Uploads\WMVVideos\video.wmv";

string mpg = @"D:\Projects\ TestProject \Uploads\Videos\video.flv";

string cmd = " -i " + "" + video + " " + " " + "" + mpg + "" + "";

System.Diagnostics.Process proc = new System.Diagnostics.Process();

proc.StartInfo.FileName = @"D:\Projects\ TestProject \bin\ffmpeg";

proc.StartInfo.Arguments = cmd;

proc.StartInfo.UseShellExecute = false;

proc.StartInfo.CreateNoWindow = true;

proc.StartInfo.RedirectStandardOutput = false;

proc.Start();

string video = @"D:\Projects\testapp\Uploads\videowmv.wmv";

string mpg = @"D:\Projects\testapp\Uploads\videoflv.flv";

string cmd = " -i " + "" + video + " " + " " + "" + mpg + "" + "";

System.Diagnostics.Process proc = new System.Diagnostics.Process();

proc.StartInfo.FileName = @"D:\Projects\Gastro\bin\ffmpeg";

proc.StartInfo.Arguments = cmd;

proc.StartInfo.UseShellExecute = false;

proc.StartInfo.CreateNoWindow = true;

proc.StartInfo.RedirectStandardOutput = false;

proc.Start();

Once this simple bit of code is working, and you learn how to use the command line and all it's proper variables, you can more finely tune your video encoding to the size and quality you desire. It should also be noted that FFMPEG works with converting MP3, MPG and many other media types, as stated in the FFMEG documentation.

FFMPEG comes with zip format 7z.

You can down load the tool to unzip 7z format from here

You can download FFMPEG from here: http://sourceforge.net/project/showfiles.php?group_id=205275&package_id=248632
