[FFmpeg-user] Recording logitech ultra vison,

[Sw@g]

Hi again,

Well with " " or ` ` it doesn't work "Unrecognized option 'preset 
medium'" only the -vpre works.

ffmpeg -f video4linux2 -i /dev/video0 -pix_fmt yuv420p -s 800x600 
-vcodec libx264 -vpre medium -crf 18 -r 15 -t 20  cam_`date +%F_%T`.mp4

And sorry to bring it up, but mencoder call the profile high and the 
quality is great, but I do not know the command to call it.


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
       --tune <string>         Tune the settings for a particular type 
of source
                               or situation
                                   Overridden by user settings.
                                   Multiple tunings are separated by commas.
                                   Only one psy tuning can be used at a 
time.
                                   - psy tunings: film,animation,grain,
                                                  stillimage,psnr,ssim
                                   - other tunings: fastdecode,zerolatency
