[MEncoder-users] xvid second pass

[Marco]

Of these two pass commands

$ mencoder dolbycity.vob -oac copy -ovc xvid -xvidencopts pass=1 -o /dev/null
works

$ mencoder dolbycity.vob -oac copy -ovc xvid -xvidencopts pass=2 -o out.avi
gives me

File not found: 'frameno.avi'
Failed to open frameno.avi
Using SSE optimized IMDCT transform
Using MMX optimized resampler
The selected video_out device is incompatible with this codec.
xvid: you must specify one or a valid combination of 'bitrate',
'pass', 'quantizer' settings
FATAL: Cannot initialize video driver.

What's wrong?

Thanks,
Marco
