h264 mp4 index to front command line

Question

Is there any command line tools to move an h264/mp4 index to the beginning so that flash will start playing the file quicker over the net? I am aware of the tool QTIndexSwapper however it is not command line.

Alternatively is there an ffmpeg command to place the index at the front during an encoding?

Thanks.

After enough poking around I managed to find a python script called qt-faststart that does it. So far so good. qt-faststart
