ZoneMinder Forums

When I run zmc -d /dev/video it returns immediately with error code 255 and I get this in the logs:

08/08/08 20:43:13.080096 zmc_dvideo[3088].ERR-zm_local_camera.cpp/162 [Failed to setup memory: Invalid argument]

I have a sony dcr-pc9 mini-DV camera plugged into a hauppauge 150 capture card on a plain LFS linux system with kernel 2.6.24.7 and ZoneMinder 1.23.3.

I have used v4l2-ctl -i 2 to set the camera to input 2, which is composite. I have tested everything end to end by creating an avi and putting it on the webserver. cat /dev/video0 > /srv/www/htdocs/duh.avi. I can view this avi on another machine just fine.

I have also set the shared memory sizes to something that I hope is plenty big:
cat /proc/sys/kernel/shmmax
268435456
cat /proc/sys/kernel/shmall
268435456

Here is the output of ipcs:

------ Shared Memory Segments --------
key shmid owner perms bytes nattch status

------ Semaphore Arrays --------

0x00000000 32768 apache 600 1
0x00000000 65537 apache 600 1

------ Message Queues --------

I believe this is the code from src/zm_local_camera.cpp that is failing:

if ( ioctl(m_videohandle, VIDIOCGMBUF, &m_vmb) < 0 )
{
Error(( "Failed to setup memory: %s", strerror(errno) ));
exit(-1);
}


Here is the output of zmu -d /dev/video0 -q -v

I just noticed this other logfile:

have you tested the cam on v4l with tvtime or similar?

couldn't get tvtime to build.

xawtv -nodga (had to use that option to even run) says:

v4l-conf had some trouble, trying to continue anyway

and the window is just black. So I guess v4l doesn't work. I enabled it in the kernel, not sure what else to do. Here are some kernel configs:

CONFIG_VIDEO_DEV=y
CONFIG_VIDEO_V4L1=y
CONFIG_VIDEO_V4L1_COMPAT=y
CONFIG_VIDEO_V4L2=y
CONFIG_VIDEO_CAPTURE_DRIVERS=y
# CONFIG_VIDEO_ADV_DEBUG is not set
CONFIG_VIDEO_HELPER_CHIPS_AUTO=y
CONFIG_VIDEO_TVAUDIO=m
CONFIG_VIDEO_TDA9840=m
CONFIG_VIDEO_TEA6415C=m
(all the rest of these were added as modules...)

ok, looks like pvr-150 can actually have different chipsets. maybe mine is not supported or something:
Internext Compression Inc iTVC16 (CX23416) MPEG-2 Encoder

From another thread it looks like the ivtv driver should work. dunno.

ZM is only able to use the drivers provided by the V4L1 driver currently. If you PVR-150 is the type that requires IVTV then it will not work with ZM to the best of my knowledge without some major work. know someone had started working on something a few years back, his post is in the contribs section of the forum and obviously pretty dated and really was just a proof of concept that unfortunately didn't go anywhere.

You would obviously be correct in that just because you have a pvr-150, Hauppauge is famous for changing the hardware, with out changing the model, and likely you have one of the more recent cards.

This would be the third case I know of, two of which were just this month including yours.
