> I see you point, but am still confused as to how idet or ffmpeg can tell
me whether the input is telecine
It cannot (directly) because this wasn't implemented, see ticket #3073.

But if it reports both (many) interlaced and (many) progressive frames
with numbers of the same magnitude the only explanations (imo) are that
either the stream changed from interlaced to progressive or progressive to
interlaced half way through (this is very common for long 25fps recordings
where I live due to live content vs commercials) or that the stream is
telecined.
Note that my original comment was not meant to suggest using idet, I just
wanted to make sure that you know that yadif should only be used on
interlaced content (because it damages all other content permanently).
And I wanted to know why you believe idet is unreliable (when all other
methods except visual inspection are known to simply not work, see
http://thread.gmane.org/gmane.comp.video.ffmpeg.user/42613).
