A simple example of the bug: ffplay -f lavfi color=c=gray -vf 'tmix=enable=gt(t\,1)'
After one second, the color is wrong (green in my case), not the expected gray. It seems it is due to the fact that parse_weights determines that the weights are all 1 and FAST_TMIX_SLICE should be used instead of MIX_SLICE. But if the filter is not running from the very start with these weights, FAST_TMIX_SLICE will not work properly. Besides, should FAST_TMIX_SLICE not be used with float types either, as addition on floats is not associative and rounding errors will accumulate?
