ZoneMinder Forums

hello all,
I just compiled and installed the latest source code for 1.25 in Fedora 16.
I'm using a Logitech C525 webcam. I have no image and in the log file I have a memory fault and a message saying zmc -d /dev/video0 exited abnormally. Any one experienced this?
greetings
Pedro

Hello again,
yeah I know this post is not very useful in terms of problem explanation... but yesterday I was too tired and it was too late.
I compiled zoneminder in Fedora 16 64 bits and I also increased the shared memory according to some other posts I found. But that didn't fix the problem.
I'll try to post more info about my particular problem soon.

For now I have a couple of questions:
1. Is there someone that managed to compile and make it work on a Fedora 16 X64?
2. Is there someone using the Logitech C525 camera?

Thanks in advance!
Pedro

hello again,
I see my post doesn't have many views count... no one is using zoneminder on fedora 16?

the log file is on the bottom, I just made a copy/past from the web log window, it is in reverse order, the last log is on the top, sorry.

the result of the addr2line command:

$ sudo addr2line -e /usr/local/bin/zmc 0x35dfe0f500 0x41ccb4 0x425487 0x405464 0x35dfa2169d 0x4058a1

Below is the code that crashes. the buffer must be smaller then it should... any ideas on the problem? the camera works ok using cheese application.

case V4L2_PIX_FMT_YUYV :
#endif // ZM_HAS_V4L2
{
int size = width*height*2;
unsigned char *s_ptr = buffer;
unsigned char *d_ptr = temp_buffer;

int y1,y2,u,v;
int r,g,b;
for ( int i = 0; i < size; i += 4 )
{
y1 = *s_ptr++;
u = *s_ptr++;
y2 = *s_ptr++;
v = *s_ptr++;
