Duane Gustavus:
|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
Same here :-)
|1) ... 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.
Hmm. Click the camera icon again. Then while the image is frozen, pop
some window in front of fxtv, and then pull it away, revealing the fxtv
window again. If you don't see that last image you saw when you froze
fxtv, then fxtv probably never got the signal (SIGUSR1) from the driver
that said the frame was captured.
Note that I'm running stock 3.0-RELEASE here as well (3.0-R bt848 driver
and XFree86 3.3.2). Likely though we have different H/W (capture cards, etc.)
|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
This is consistent with the above. Whenever the video window is partially
occluded (or when capturing video/images), fxtv depends on getting "Frame
Done" signals from the driver. Doesn't seem your getting these. Thus your
window isn't being updated.
|Left behind is an mpeg_encode.core file, a zero length take.AVraw file, a
^^^^^^^^^^^^^^^^^^^^^^
Yep. This is consistent with the above.
|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.
Strange. Sounds like an X server bug. I don't see that here, but I'm
running a different video card and X server.
|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.
Btn1 down does a full-screen zoom. It switches down to 640x480 using the
XFree86 video mode extension. Sounds like that is broken or misconfigured
as well.
Try using Ctrl-Alt-+ and cycling through all your video modes. Make sure
everything seems to work OK (you shouldn't see any blank screens). And
check the "Screen" section in your /etc/XF86Config to make sure you have
640x480 configured.
|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?).
Zero? Hmmm. Try:
> fxtv -xrm "Fxtv.cableStationList: 3 4" -xrm "Fxtv.tunerMode: cable"
Now try to KP_ADD.
|My intended application is to grab frames from a robot-mounted camera as
|it wanders around my house.
Sounds pretty cool! Let's me know how the above goes, and let's see the
output of:
> fxtv -debug startup
so we can get to figuring out why you aren't getting frame done signals.
