I would suggest:
1) Create a producer to open V1 (it does not matter the profile)2) Query V1 for
the size3) Close V1 (delete the producer)4) Create a producer to open V2 (it
does not matter the profile)5) Query V2 for the size6) Close V2(delete the
producer)7) Calculate the profile that you want based on the size you queried
from V1 and V28) Create a profile with the new calculated profile9) Proceed to
create producers, tractors and consumers all using the same profile
I do not understand the use case you are working under. Typically people have a
target profile that is driven by the device, platform, quality or player that
the file will be used on. And then they work everything else to fit within that
profile. But your profile is being calculated from arbitrary sized sources.
Maybe this does not apply to you because any non-standard profile will work for
you. But this is uncommon in my experience.

Right now, when I stack videos vertically, I output the Tractor and the
Profile: "tuple[tr:Tractor; p:Profile] "proc stackVertically*( v1,v2:Producer
):tuple[tr:Tractor; p:Profile]
Later I apply the returned profile to the consumer: # Call the function to
stack vertically two videos. # The tractor and new profile are returned var
(newProducer, profile) = stackVertically( v1, v2 ) # Consumer using the new
calculated profile var sdl = profile.newFactoryConsumer( "sdl2" )
sdl["terminate_on_pause"] = 1
# From tractor to SDL2 newProducer > sdl
What I would like to do is to apply the profile to the tractor. Like moving the
consumer within the stackVertically function and then using that consumer as a
producer.
I see that there is this plugin to use a consumer as a producer:
https://www.mltframework.org/plugins/ProducerConsumer/
but it is not very clear how I should use it and if it is appropriate for this
purpose.
On the other hand, I wonder if I should get the producer from the tractor and
set "width", "height", "aspect_ratio". I am trying this last option without
success.
Any suggestion is welcomed.
