I cannot reproduce the memory issue, please
test current FFmpeg git head.

It happens on both local machine and server for me. I'm using a pre-built version of ffmpeg from http://johnvansickle.com/ffmpeg/

Unrelated: This options have no effect,
please remove them.

I don't know how to disable these

These should probably also be removed.

The native encoder is of better quality
(I was not allowed to add a warning at runtime.)

How do I enable this with pre-built from link above?
