Using eq() on floating points is indeed a bad idea because of floating
point rounding.
In the code of the select filter I've found:
#define TS2D(ts) ((ts) == AV_NOPTS_VALUE ? NAN : (double)(ts))
select->var_values[VAR_T ] = TS2D(frame->pts) *

If you want support on this mailing list, do not use -v warning
and post the command line together with the complete, uncut
