[FFmpeg-user] Faststart fragmented mp4

Carl, 

I have done a few more tests with some noticeable results. 

(case 1) I was able to get the sidx atom to be inserted by adding [frag_keyframe] and setting [frag_duration] to 0 , but this results in a file that does not playback past the first GOP I believe. (  Let me know if you need me to place it in an ftp) 

(case 2) I then changed the [frag_duration] to 1000 which is the original value, this results in the sidx atom failing to insert. 

Below are both uncut console results:
