I think It's possible if we understand the structure of mp4/3gp file.
Actually I'm not expertise about this issue, It need more time work
around to find the solution. Sorry I can't help you.
About my project, I ported ffmpeg library to android successful. and I'm
writing a new application to extract exactly the frame we request using
ffmpeg (using function av_read_input_stream and av_seek_frame). I hope
this will work, right now I'm not sure about the performance of this
library in Android, I think It will not extract all frames, but just
seek to requested frame. I will let you know when I have the result.

I want to ask about the possibility to make an mp4/3gp file streamable
without need of post processing using tools like qt-faststart. I am writing
a tool which needs to be able to stream the data as it is beeing encoded so
post processing solutions are not an option. Another containers except mp4
and 3gp are also not an option. So is there any way in ffmpeg to write the
moov atom on start of the encoding even if the moov atom is not fully
correct and complete. Something like a fake moov atom which just to allow
playng after this even if progress or other metadata is not fully correct?
Is this possible at all even without ffmpeg and using other encoders ?
