how to make mp4 for streaming

Use ffmpeg, FAAC and MPEG4IP to make mp4 for streaming

1. To extract the audio track from the source
   
   ffmpeg -i input_file -vn output_file



2. To encode the raw PCM audio track split by FFmpeg: (use FAAC)
   
   faac -m4 -b64 -r48000 -pLC input_file output_file # for older version
   faac -m 4 -b 123 input_file output_file # for newer version
   
   
3. encoding to ISO MPEG-4 video (bitrate: 300 kbps):
   
   • One pass
     
     ffmpeg -i input_file -an -b 300 -vcodec mpeg4 output_file
   
   
   
   • first pass
     
     ffmpeg -i input_file -an -pass 1 -passlogfile log_file -qscale 2 -vcodec mpeg4 output_file
     
     second pass
     
     ffmpeg -i input_file -an -pass 2 -passlogfile log_file -b 300 -vcodec mpeg4 output_file
     
     
4. Multiplexing: combining the Audio and Video (using MPEG4IP)
   adding a video track
   
   mp4creator -c myvideo.avi -hint mytest.mp4
   
   adding a audio track, -interleave not needed for MP3
   
   mp4creator -c myaudio.aac -hint -interleave mytest.mp4
   
   optimize it
   
   mp4creator -optimize mytest.mp4

After that, you can use Darwin Streaming Server to stream the MPEG-4 clip.
