How to Run ffmpeg commands using .Net
-
Hi Friends, I have to run ffmpeg commands(userd to Transcode audio and video) from c#. Actually I'm trying to make one dll with one method which does this transcoding of audio and video. ex: c:\\ffmpeg\\bin\\ffmpeg.exe -i c:\\ffmpeg\\bin\\ish.mp4 -y sample.mp4 The above command generates one sample.mp4 video file by taknig ish.mp4 as input. This is not fixed commands will generate at runtime based on the input file. So I want to run this command from .net. I tried by using
string path = "C:\\ffmpeg\\bin\\ffmpeg.exe"; string fileargs = "ffmpeg -i ish.mp4 -s cif -vcodec h263 -acodec libamr_nb -ar 8000 -ac 1 -ab 12.2k sampleish12.3gp"; Process p = new Process(); p.StartInfo.FileName = path; p.StartInfo.Arguments = fileargs; p.StartInfo.UseShellExecute = false; p.StartInfo.CreateNoWindow = false; p.StartInfo.RedirectStandardOutput = false; p.Start(); p.WaitForExit(50000);but it is not giving any output file Thanks HariBabu -

This is how your command sent in code differs from your example.
