[FFmpeg-user] minterpolate problem

[Mark Filipak (ffmpeg)]

I ask this because I think it can only be answered by looking at the source code. I'm not competent 
to do that.

Is 'mi_mode=dup' or 'mi_mode=blend' or 'mi_mode=mci' the default?

Thank you. It works for me, too. I don't know why it didn't work the 1st time (except maybe because 
I have so many balls in the air).

So, unlike what is shown in the documentation, 'mc_mode' is _not_ an argument of 'mci'.

Apparently, 1, 'mi_mode=mci' is a valid argument and, 2, that 'mc_mode' (and perhaps 'me_mode' & 
'me') are valid solely if mi_mode=mci but are otherwise not arguments of 'mi_mode=mci' but are 
direct options of 'minterpolate'. That kind of scope is probably what the author intended when 
he/she indented them below 'mci', but the indenting is very misleading.

I will try all combinations of minterpolate to resolve all the options and issues and return with a 
new beautified version of the minterpolate documentation. Perhaps that will save people in the 
future because minterpolate is an important and amazing function.
