Jeremy Porter:
|I've gotten my system to be able to display video in a window

|AMD K5-133 and doesn't have a lot of horsepower, but that
|doesn't seem to be the problem. The save image feature doesn't
|work it reports "No frozen image". The freeze image button doesn't
|seem to matter here.

Amancio Hasty:
|I think that there may be a problem with fxtv saving non-interlaced images

No, no problem's ever been reported with freeze-frame of images, single or
double field.
I suspect this is the "Bt848 driver isn't issuing frame completion signals"
problem that I'm helping Alex Nash <nash@mcs.net> with now. Look in your
-multimedia list mail for the thread labeled: "Re: Bt848: no IRQ".
Jeremy, a few questions about your system config to try and nail this down:
- FreeBSD version (2.2.6, 3.0-current [how current])
- Is your system SMP?
- Fxtv version
- Capture Card (e.g. Hauppauge WinTV)
- Capture Card Tuner (e.g. Philips FR1236MK2)
- dmesg output. E.g.:
bktr0: <BrookTree 848> rev 0x11 int a irq 9 on pci0.11.0
Hauppauge WinCast/TV, Philips NTSC tuner, dbx stereo.
- Relevent kernel config lines
- "fxtv -debug startup" output
Finally, please grab the source for Fxtv-0.46
(http://multiverse.com/~rhh/fxtv), and add this line to the top of
tvcapture.c::TVCAPTUREFrameDoneSigHdlr():
static void TVCAPTUREFrameDoneSigHdlr()
{
printf( "Got a frame!\n" ); /* <--- Add this line */
S_frame_done_count++;
Then compile fxtv, run it, and freeze a frame. If you don't see:
Got a frame!
the driver's not issuing signals to Fxtv like it should.
Thanks,
Randall
