Hi,

I want to pass as much of rescaling/resampling/color conversion tasks
to my consumer as I can. So, when calling, e.g. mlt_frame_get_image()
for image, I want to use parameters that guarantee the least number of implicit
conversions will take place, as I can take care of them in my consumer. What’s
the best way to do that? Is there some way to ask a „loader" producer to produce
„the most native” frame possible?

Example - when I pass „mlt_image_rgb24a” to mlt_frame_get_image(), the MLT
loader producer does its best to produce what I want, so on some video sources
there is an implicit y420->rgba conversion. But my consumer could handle y420
as well, so I could avoid this conversion. Question is, how to know which format
to request, to avoid such conversion?


Best,
Paweł
