Yes with a movie at 25 fps, but actually i would like to have something
'automatic' :
if my movie has been encoded at 10 fps, i would like to have a [metro
100]. Or, if the movie has been encoded at 30 fps, i would like to have
a [metro 33], etc.
That's why i need to use the value from [pix_film]. The problem is the
value i get from [pix_film] is sometimes wrong (12.5 fps instead 25 fps
for one of my movies). So my movie play very slow.
However, VLC returns the good value with the same movie (25 fps).
I would like to know, is there a method to avoid this problem (install
other libs and compile to manage movies in GEM or something else ?).
