Re: [MPlayer-users] TV: Red is pink

[Oak]

Hello again,

when I add "hue=-15", colors appears to be almost all right... I.e.:
mplayer tv:// -tv channels=56-RTE2,66-TV3,52-RTE1:driver=v4l2:outfmt=rgb32:norm=PAL:width=768:height=576:brightness=52:contrast=50:saturation=35:hue=-15:volume=80
vf=crop=690:500

I have question to developers: Why options "contrast", "brightness", "hue" and "volume" are not set to some reasonable defaults? I.e. volume=50...
In example, I had bad times figuring out why mplayer doesn't work with my TV card, when everything appears to be all right  - added "brightness=50" and hey! A picture emerged from a black screen!! Other apps have reasonable settings, shouldn't be problem to fix that, isn't it?

Why "hue=-15" works best? Why negative value? Is this for purpose or HW problem?

Thanks in advance for all my wondering questions.

Oak
