HI! I am completely lost. I am new to V4L2 (and linux OS). I am trying to acquire video from an ultrasound machine so that I can capture the image on my PC that is running linux (SuSE 7.3). These are my specs: OS: SuSe 7.3 kernal: ver 2.4.9 XFree86: ver 4.1.0 graphics card: ATI XPERT 99 16 MB AGP (1) I've compiled km (obtained from the GATOS project), (2) I think that I've installed km properly (how would I know?). (3) I've installed the ATI drivers (as was described by GATOS). (4) I 've upgraded to XFree86 4.1.0. (5) I've installed VideodevX (5) I've compiled and run AVview I get no video image on my pc. Am I installing the data in the wrong order. Can you please tell me what to do, step by step? Thanks a bunch. Also, did I have to upgrade to V4L2 in order to acquire video on my linux pc? Would the orginal V4L API that comes with the linux OS have been sufficient? Thanks.
