I'm having a problem with fxtv 0.45, the latest bt848 driver
(2.2-stable as of about two days ago), and WinCast/TV dbx.
Specifically, fxtv dumps core. Here's what I got from gdb:
Starting program: /tmp/fx/./fxtv
Xlib: extension "XFree86-DGA" missing on display ":0.0".
Xlib: extension "XFree86-VidModeExtension" missing on display ":0.0".
Warning: Actions not found: TVSetChannel
Program received signal SIGBUS, Bus error.
0x17e1b in TVSCREENGetCurVidModeGeometry (s=0x63860, width=0xefbfd662,
height=0xefbfd660) at tvscreen.c:180
(gdb) print *s
$1 = {display = 0x6b800, screen = 0, visual = 0x74a00, visual_modes =
0x7e0e0, num_visuals = 3, active_visual = 2, fb_visual = 0x74800,
base_addr = 0, pitch = 0, bank_size = 0, ram_size = 0,
vmode_ext_supported = 0, vmode_majv = 0, vmode_minv = 0, vm_list =
0x0, vm_list_len = 0, vm_startup = 0}
Line 180 attempts to dereference vm_list, which is NULL. What I don't
know, is why vm_list is NULL.
The card appears to work properly under Windows (after I yanked out my
SMC network card :). Also, I briefly had a version of fxtv 0.44 which
would start up and display static, but could not be coaxed into
displaying anything from my VCR. I thought this might be a
kernel/user level mismatch (the program was built against older
sources), so I grabbed 0.45 to get everything in sync.
Any ideas would be greatly appreciated.
