[FFmpeg-user] Recording logitech ultra vison,

Right,

So I am still trying to get the best possible video quality, and looking 
at the mencoder command the x264 profile is set to high - but trying to 
use the -vpre setting doesn't work since it refer to x264 --preset, I 
was trying to get the ffmpeg command for x264 --profile without success.

Presets:

       --profile <string>      Force the limits of an H.264 profile
                                   Overrides all settings.
                                   - baseline,main,high,high10
       --preset <string>       Use a preset to select encoding settings 
[medium]
                                   Overridden by user settings.
                                   - 
ultrafast,superfast,veryfast,faster,fast
                                   - medium,slow,slower,veryslow,placebo


So any idea what is the command?
