Okay. I figured it out now, thanks guys. But now back to the Progress Bar. I think I might have mentions this, but I am making my own GUI for x264. I want it to have a progress bar for when the video is getting encoded (Audio, Demuxing and Muxing too) , but how do I do that? Right now it just show the command prompt but if there is no index in the video, no time will be displayed on how long it will be. So how do I hide that, as well as make a progress bar in a new window that will show the progress, how much time is left, how fast it is going VIA fps, what frame it is on and out of what frames, and what time position it is on and out of how long.
An example of what I mean bu the last two things ("what frame it is on and out of what frames, and what time position it is on and out of how long") is:
Frame: 107300/140050
Time Position: 00:07:21/01:48:27
