I think there is a misunderstanding here. 
In a first approach, i was thinking that it was possible to provide 
a pipe to create subtitles, with a particular picture format.
Hence my sentence, saying that my application will provide the
Subtiles.  In fact, the correct sentence would be ; 
"my application will provide the input pictures 
used to build the subtiltes".

Right now, i stopped using the ffmpeg binary solution, and i am
calling directly from my application the libavcodec/libavformat

I am able to generate a MPTS with H264+subtitles, but when i 
replay it, I am facing issues with the framerate and PTS/DTS.
I will post a separate mail on this.

Regards (and happy new year), SF.
