Hi, I'm using bttv driver for capturing video image and have a problem. I have a video camera and a video capture card made in Japan, so I use XawTV or other application (e.g. EffecTV, my project:) with setting NTSC-JP norm. Then, there is a narrow (about 4 pixels) black column on the right side of captured image. I think that I can eliminate this black column by tuning the parameters of tvnorms[], but I cannot realize the meaning of each parameter. Can anyone advice me how to tune them for getting good image? I hope that those parameters can be configurable from application.
