How do I find ffmpeg arguments on the command line what each argument does?

Question

I have this code:

public void Start(string FileName, Bitmap Sample_Bitmap, int BitmapRate ) { p = new NamedPipeServerStream(pipename, PipeDirection.Out, 1, PipeTransmissionMode.Byte); byte[] b = new byte[1280 * 720 * 3]; // some buffer for the rg and b of pixels of an image of size 720p System.Diagnostics.Process process = new System.Diagnostics.Process(); process.StartInfo.FileName = @"D:\pipetest\pipetest\ffmpegx86\ffmpeg.exe"; process.EnableRaisingEvents = false; process.StartInfo.WorkingDirectory = @"D:\pipetest\pipetest\ffmpegx86"; process.StartInfo.Arguments = @"-f rawvideo -pix_fmt rgb24 -video_size 1280x720 -i \\.\pipe\mytestpipe -map 0 -c:v libx264 -r " + BitmapRate + " " + FileName; process.Start(); process.StartInfo.UseShellExecute = false; process.StartInfo.CreateNoWindow = false; p.WaitForConnection(); } 

So, I know what BitmapRate and FileName do, but the rest are arguments.

What does that mean -f ? and rawvideo is that of decoders or encoders ? -i ? -c:v ? libx264 ? -i ? -c:v ? libx264 ? -i ? -c:v ? libx264 is the codec i guess and -r ?

I tried in google for this format of arguments, but did not find it.

I have 4 lists of text files:

encoders.txt decoders.txt In both files, I have rawvideo. I have pixfmts.txt and fileformats.txt .

I want to build an argument string from variables.

So, for example, BitmapRate is an int, and FileName is a string. And the rest of the arguments, what types of variables do I have to put in order to enter a function?

for instance

what rgb24 what type? 1280x720 what type of variable should it be?

Have you seen this link?

It can answer some of your questions on parameters, including 1280x720. Thanks to this, I hope you can match your requirements (using ffmpeg.exe!) And check!
