I have a couple of matters that I thought I would reach out to the 
communiuty for some wisdom.

1 --------------------------------------
FFplay showing "right" color of dpx 10bit log
in the recent cellar ietf.org doc FFV1 and Film   by Joshua Yocum


pg six reads

  Colors in ffplay -- There seems to be some inconsistency with how 10 
bit log videos look in
ffplay compared to other video players (see section on this in Detailed 
Comparison for more

My Q is :  what do you think?

2 ------------------------------------------------------

This also fits squarely in the area of wondering...

does anyone know of - or - might it be possible to

have a test of a dpx seq and Prove that it is log or linear.

presently I just eyeball f.dpx apply a lut

what I might wish i had was something like

ffprobe < test for logness > 0001.dpf

and it returns y or n

I wish for a objective "test"

Thanks much
