[RESOLVED] Process.Start() => speed-- vs. Console

[gu471]

Hi,

I want to make the process of ffmpeg visible to a progressbar. While caring for it, I mentioned that running ffmpeg via

 strCmdText = "-y -i \"" + path + "\"";
 strCmdText += " -async 1 -vf yadif -c:v libx264 -b:v 1024k -r 30 -bf 1 -an nul.avi";
 Process.Start(new ProcessStartInfo("lib\\ffmpeg.exe", strCmdText));

is about 2/3 slower than running it in console (app: 130 progress fps, console: 400 progress fps).

I already tried to run the Process.Start in an extra thread.

The CPU usage is 75% while running in console, but 100% while running in the app.
RAM usage is the same.

Is there a way to fix this?
