[MEncoder-users] x264 Encoding problems - Video Driver Initialization

[briaeros007]

Hello

x264 [error]: no ratecontrol method specified

IMHO, you must specify, with the help of -x264encopts the bitrate or any
other options (subq, ...) which will determine the quality of the stream.

More informations on theses options can be found there
http://www.mplayerhq.hu/DOCS/HTML/en/menc-feat-x264.html

I Hope it will help ;)
