[MEncoder-users] how to split 8gb wmv bluray wmv file (VC-1 codec)

[Valent Turkovic]

Hi,
how can I split large 8GB file to a few smaller ones using mencoder?

As I can see the issue is that wmv uses Variable Frame Rate (VFR) and
that is mainly the issue...

The file I use is 2h long, and I can make the split of the first hour
but I can't make the split from 1st hour till the end...

mencoder -oac copy -ovc copy -o ./Part1.wmv -endpos 01:00:00
./bluray_full_movie.wmv

but when I try this:
mencoder -oac copy -ovc copy -o ./Part2.wmv -ss 01:00:00 ./bluray_full_movie.wmv

it fails :(

Too many audio packets in the buffer: (256 in 8388608 bytes).
Maybe you are playing a non-interleaved stream/file or the codec failed?
For AVI files, try to force non-interleaved mode with the -ni option.
