Well, I had a little time to experiment with the Bt848 driver/fxtv this weekend/yesterday, so, since I understand that fxtv-0.45 and the updated Bt848 driver are in the 2.2.x and 3.0-current source trees, I upgraded to the latest (late Saturday) 2.2 RELENG, soon to be 2.2.5. I wanted to test the soon-to-be-2.2.5 release wrt the Bt848. It appeared to have updated fxtv and bt848 drivers. I did a "make world" overnight, it worked, and fxtv and video in worked. A few complications. [Of course, I ran into the same "TVSetChannel" problem, but, that was easily fixed by the advice on "freebsd-multimedia".] Somewhere in all the upgrades, [I freely admit that during upgrades operator error is a possibility}, I have experienced two new problems. First, the vic 2.8 framegrabber no longer seems to detect the Bt848, as it did before, so, I can't do video input to vic. Was a change to vic required to support the modified driver? It was working Saturday (I checked), before the cvsup and "make world". Are there any modifications to the vic source needed to go with the latest driver? As I said, this was working before the upgrade, and I did not upgrade vic, so the change would have had to have been in cvsup'ed system source or in one of the /usr/ports dependent libraries, some of which may have been updated since vic was last built. Now, fxtv-0.45 works in 8-bit color mode (I was expecting a somewhat different user interface from fxtv-0.44, but it looks the same to me - do I have an X resources problem?), although, fxtv seems to ignore the channel selection X resources that I had set before (but, you can go up and down one-channel-at-a-time) in the channel space. Was there an announcement of new X resources to set/handle the channels? Is there another way to do this now - I saw no menu. In any case, I assume that all this will sort itself out over time and has nothing to do with the driver changes. The other, potentially serious, problem is that in (32-bit) Truecolor (using an ATI Graphics Xpression), a large horizontal band of what appears to be every-other line (e.g. even or odd?) is messed up. I don't have the exact dimensions, but, I would say that this band goes perhaps from lines ~120 to ~300 on the displayed video image. Now, I did see a similar effect before with 2.2.2-RELEASE and fxtv-0.43 or -0.44 (somewhere in the June-August timeframe), and, after recompiling and reinstalling everything in September, it mysteriously went away. But, now the problem is back. I tried cleaning, deleting, and reinstalling from port source, a few things, but, it made no difference. 8-bit color mode still works fine. I also tried running the old fxtv, which I had squirreled away, and, it produced some error messages and wouldn't run. I have not tried reinstalling the old driver, because, I think there is some new ioctl or something the new fxtv needs. But, if I'm wrong about that, I could try putting the old driver back. Environment: 2.2-RELENG as of Saturday, including the now-included Bt848 driver, which appears to have been updated properly (previously, I had the ~June driver hand-installed), fxtv-0.45, ATI Graphics Xpression, XFree86 3.3.1, using the Mach64 X server. So, anyway, has anyone else tried the almost-2.2.5 release with fxtv-0.45 using the X server in truecolor mode, and, if so, anything odd? It may have something to do with the relatively slow ATI card, but, it was working since early September using 2.2.2, fxtv-0.44, and the (June?) driver. -Hugh LaMaster Hugh LaMaster, M/S 258-5, ASCII Email: hlamaster@mail.arc.nasa.gov NASA Ames Research Center Or: lamaster@nas.nasa.gov Moffett Field, CA 94035-1000 No Junkmail: USC 18 section 2701 Phone: 415/604-1056 Disclaimer: Unofficial, personal *opinion*.
