Summary of the enhancement request:
bitand (and bitor) operations function at 8 bit, I'd like to use bitand to
work with the lower bits of some 10 and 16 bit video but it seems that
bitand only finangles the first 8 bits.
Here is a command I would use to solo the 8th bit of the Y plane. I would
like to do similarly with lower bits.
{{{
bit=8
ffplay 10bit_v210.mov -vf
"extractplanes=y,lut=c0=bitand(val\,pow(2\,8-${bit}))*pow(2\,${bit})"
}}}
