[MEncoder-users] Aspect ratio signaling

[Pierre Catello]

Hello,

Some mpeg2 transport streams change the aspect ratio quite often (movie
review programs, programs with movie + debate, etc.)
The mpeg2 transport stream has proper signaling, but is it possible to
include aspect ratio change signals into an AVI...
If it is not possible, does anyone know a way to map aspect ratio signaling
from mpeg2 program or transport streams to an MP4 container ?

Thanks
