[MEncoder-users] Help with mencoder

[JD]

I did. And it is failing with continuously repeating error messages of

x264 [error]: This build of x264 requires high depth input. Rebuild to 
support 8-bit input.
x264_encoder_encode failed

I think my x264 libs are compiled with the wrong option and
thus do not support 8-bit input.
