  ffmpeg -i input.mp4 -vcodec libx264 -vpre libx264-hq -b 1500k output.mp4

  This will create a H.264 stream in a mp4 wrapper at 1500 kbps. It will be at the original image size as -s was not specified.

  You will need libx264 installed and enabled for this line to work. libx264 produces H.264 streams and is highly recommended.

  Thank you for your reply. I want to do MP4 to H.264 conversion using C program in ffmpeg. Do you have any idea/sample code for that?

  Thank you,

  Not too sure about what you mean by “C program”.

  Do you mean writing a program in C++ that uses ffmpeg or simply running ffmpeg in the command line?
