The saa7134 module standardizes on /dev/video0 I believe. Well, the new v4l1-compat module isn't a functional replacement for the 0.1.x (old API) v4l1-compat yet (sorry, Gerd). I'm not familiar with the innards of the module, but it's definitely not behaving identically since mplayer 0.90rc4 works fine with the older API, and not with the newer API. e.g., with the new API, someone just posted that we need to do ''v4lctl volume mute off'' to unmute the sound in mplayer (we get sound finally). This means that some initialization is not done in the new v4l1-compat. I guess this may be an impetus for apps developers to adopt v4l2 correctly instead of relying on the v4l1-compat layer. As to how v4l1-compat *should* work, you'll have to ask Gerd. T.C. ---- Wan Tat Chee (Lecturer) School of Computer Science, Univ. Science Malaysia, 11800 Minden, Penang, Malaysia.
