Output: base profile, level 13, no b frames. 
Input: wmv, 320x240

You can call that zero information I suppose. There's also zero information
in your question. What does settings mean? Samples? (bitrate? Quality?
Container? The amount of sugar in my coffee?)

I am just passing information, not stating the one and only precious x264
encoder should be replaced. 

Your (L-)GLP license statement makes little sense btw (as the IPP encoders
do not need to be compiled into the Libav* dll's. Unless you want to take
"viral" to a new level). "My license" refers to the part one purchases from
Intel (the binaries). 

Sigh. Trying to suggest/state anything on this mailing list that touches the
[zealot] opinions of people is hopeless. 

Lighten up. Go have a smoke or something.
