Hi, Following the suggestion at the end of the README included with fxtv, I am reporting some problems in hopes someone can give me ideas where to look. OS = FreeBSD-3.0.0 installed from CD XF86332 with XF86_S3 server Pentium 66mhz processor 48 meg RAM Diamon Stealth 64 Video VRAM PCI fxtv ver 0.47 installed from ports tree mpeg_enocde installed from ports tree Hauppage WinTV model 404 Symptoms: 1) It appears fxtv is working fine when I run it with no options. The tv window appears and displays video (I am using a video camera with the Input menu set to video). When I click on the camera icon, the image stops (which I assume is freeze). When I click on File->Save Image a dialog box pops up that says "No frozen image to save." The same thing happens with Save Image As. In other words, I cannot find a way to save an image. 2) To try to save a video stream, I select File->Save Video As ... and the FXTV Save Video Control dialog pops up (the tv window goes black). I enter "take" for a file name base, target MPEG, leave size 320x240, leave format RGB (16bpp 565), leave Speed 30, and Image Encode PPM. I disable Audio Capture since I have no sound card. I click on Record, the tv window stays black, a few seconds later I click on stop. A dialog pops up with a message about converting the images, and it is replaced by a dialog that says Video conversion failed, CMD = take.sh, status = 0x0100. Left behind is an mpeg_encode.core file, a zero length take.AVraw file, a zero length take.mpg file, take.param and take.sh files that appear to be correct (ie useful data in them). I assume the mpeg_encode core dump is due to the zero length of the take.AVraw file. The entire time the Save Video Control dialog is up, the tv window is black. When I dismiss the dialog, the tv window becomes active again. 3) I am using WindowMaker 0.50 as a window manager. When I click on the Resize button (or use Btn3Down), the tv window becomes larger and appears to be working fine. When I click on Resize again, the entire screen goes blank with only the mouse indicator showing. The mouse is live and the indicator changes as I move it around the screen (ie into text mode when it passes over an xterm window). If I move it to the very bottom of the screen in either the right or left corner (not in the middle however), everything will reappear with the tv window back in the smaller size. I can do this repeatedly with the same behavior. 4) Btn1Down (or z or Return etc) in the tv window will turn the entire screen blank and freeze the mouse indicator. Clicking again will leave the screen blank but display the mouse indicator again, which will redisplay the screen by using the method mentioned in symptom three. 5) I do not have anything connected to the tuner, so I'm not sure this is a problem. None of the methods for changing the tuner seem to work. I select the tuner as input (TUNER IN shows on the tv window), and try KP_ADD/SUBTRACT and the arrow buttons on the tool bar display. The channel indicator stays at zero. Eventually I will start getting beeps (perhaps to indicate there is no tuner input?). 6) The KP_INSERT/DIVIDE/MULTIPLY keys seem to work correctly. When I try F2 to capture, I get the same error dialog about no frozen image (with the camera icon set to freeze the image in the tv window). One additional item is that I always see a message about failing to open /dev/mixer unless I start fxtv with the -noAudio option. This seems reasonable since I have no sound card, and starting with the -noAudio option does not seem to change the behaviors above. Since it appears to be so close to working, I was hoping you could tell me something I have overlooked or misunderstood in the README. My intended application is to grab frames from a robot-mounted camera as it wanders around my house.
