I already use such a tool.
One home-made, ffmpeg segment and multicat.
All this 3 tools make ts file without cut in a middle of a frame, none 
of them are very good for me (start with a keyframe AND  be accurate 
with the duration).

I'll start another threads to explain/speak about another point with 
these files.
