On peut sans doute continuer en francais mais on va se faire allumer. 
you are right yuv4mpeg is 420. So scripting in a y4mtoqt with yuv4mpeg is 
pointless.
I will stick to quicktime for linux for my 10 bits files.

It seems to me that yuv4mpeg produces only yuv 4:2:0 video stream. Is that 
correct ?
When I pipe the yuv4mpeg stream to 'ffmpeg -i - -vcodec copy %', the video I 
get is yuv420p.
(Sorry for my bad english).
