Hallo
I have after 5 years upgraded my system to a new one. I am running a 64
bit kernel. Have compiled the mjpegtools. Not the kernel, still using
the opensuse 11.0 kernel: 2.6.25.5-1.1. I have 4GB of RAM in the machine.
I have discovered a problem with lavrec. It fails with that error message:
> lavrec -f a -i P -d 1 -q 55 -a 0 test03.avi -v 2
INFO: [lavrec] Recording parameters:
INFO: [lavrec] Output format: AVI
INFO: [lavrec] Input Source: S-Video PAL
....
++ WARN: [lavrec] Closing file(s) and exiting - output file(s) my not be
readable due to error
**ERROR: [lavrec] Error syncing on a buffer: Timer expired
INFO: [lavrec] Opening output file test03.avi
[2]+ Done xawtv -c /dev/video
Segmentation fault (core dumped)
---END---
dmesg give that information:
Buz[1]: jpg_sync() - timeout: codec isr=0x04
lavrec[5148]: segfault at 7fe004d91000 ip 7fe006af85ad sp 41beeb18 error
4 in liblavfile-1.9.so.0.1.1[7fe006af3000+13000]
When I analyze the crash dump with ddd I get that information:
#0 scan_jpeg (jpegdata=0x7f5643554000 <Address 0x7f5643554000 out of
bounds>, jpeglen=0, header_only=0) at lav_io.c:126
/home/bernhard/download/cvs/mjpeg_play/lavtools/lav_io.c:126:3378:beg:0x7f56452bb5ad
(gdb) print jpegdata
$1 = (unsigned char *) 0x7f5643554000 <Address 0x7f5643554000 out of bounds>
(gdb) list 'jpegdata'
Line 109 of "lav_io.c" is at address 0x7f56452bb540 <scan_jpeg> but
contains no code.
A backtrace gives me that information:

---END---
No I am a bist lost here. Has anyone a hint how where I should take
further looks to find out more about the problem. And fix it ?
That is not a buz specific problem I it also happen with the DC30.
auf hoffentlich bald,
