Could you point me where in the code this is done? Since is not the
behaviour that I can observe. Length (which for your answer I guess is
calculated using file size) is never updated once a file is opened.

But position is currently being updated very often, isn't it? Sorry if I misunderstood what you said.
I'm going to try what you suggest in http://git.videolan.org/gitweb.cgi?p=vlc.git;a=commit;h=3b729128a6e2a0e0018c0f32bcd4ee611850b038 and see how well it works.
