I have been playing with direct webcam access via mplayer.
I use this command to view my camera.
mplayer tv:// -tv driver=v4l2:width=1024:height=720: device=/dev/video0 -vf screenshot
I am trying to understand the v4l2 options; how to find which options are available and which manuals , files, or program outputs can tell me which device can use or benifit from each option. so for example I know that to controll the brightness or contrast within this code you add
anywhere, but what other commands/options can be added this way and which manuals should i read, or is there a type of "list all options for device" command? I Have already googled' my problem and came up confused, i dont know what to ask about.
