Copying audio stream from a source file to a trancoded video file using ffmpeg

I have built my own video-only transcoder using开发者_StackOverflow ffmpeg without audio. I do not want to transcode the audio. What will be best way to add the audio stream from the source file to the transcoded file using FFMPEG API?

Try -acodec copy, e.g. something like this:

ffmpeg -i your_input.file [your video transcoding options] -acodec copy your_output.file
