  hevc : rename hevc.[ch] to hevcdec.[ch]
  This is more consistent with the rest of libav and frees up the hevc.h
  
  name for decoder-independent shared declarations.

• How do i know in the ffmpeg arguments command line what each argument do ?

  24 mai 2013, par Revuen Ben Dror

  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 r g 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 do and the FileName but the rest of the arguments.

  What odes it mean the -f ? and the rawvideo is that from the decoders or encoders ? -i ? -c:v ? libx264 is a codec i guess and -r ?

  Tried to google for this arguments format but didn't find any.

  I have 4 text files lists :

  encoders.txt decoders.txt in both files i have rawvideo too.
  I have pixfmts.txt and fileformats.txt files.

  I want to build the arguments string from variables.

  So for example BitmapRate is int and FileName is string. And the rest of the arguments what types of variables each one i should put to get in the function ?

  For example

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

  lavfi : rename AVFilterFormats.format_count to nb_formats
  This is more consistent with naming in the rest of Libav.
