There is no such function, the encoding properties that are not necessarily
related to each other are not arguments to anything. These properties are
in parentheses because they are - from FFmpeg's point-of-view - less
important for decoding than resolution, aspect ratio and other properties.
"tff" and "bff" do not necessarily imply interlaced (or telecined) content,
while "progressive" can theoretically be interlaced (or hard telecined) it
is very unlikely.
