Zoneminder - Unable to requeue buffer due to not v4l2_data

ale_arco · 2015-11-12 14:54:11

I all ...

I am new to the forum, sorry if I make some errors and for my english. Some days ago I read a lot of video surveillance. I immediately marked Zoneminder that seems to be the best open source program available on web. I decided to install everything on Arch Linux distribution that I consider lightweight with high performance and there is a lot of documentation if I need. I installed the GIT version present in AUR, all okay no errors. When I connected my WEB CAM for test, has started the problema. I can not understand the error, I tried everything but nothing, probably the solution is simple but my continuous attempts and failures probably don't see it. Probably some of you has happened this error and can help me show the way of the solution.

Situation :
OS Version : 4.2.5-1-ARCH #1 SMP PREEMPT Tue Oct 27 08:13:28 CET 2015 x86_64 GNU/Linux
WebCam : Philips SPC230NC
ZM Version : zoneminder-git 1.28.100.r5095.4.e8f31d7-1
Errors : zmc_dvideo0[757].WAR-zm_local_camera.cpp/2041 [Capture failure, possible signal loss?:Input/output error]
zmc_dvideo0[757].ERR-zm_local_camera.cpp/2178 [Unable to requeue buffer due to not v4l2_data]

Many Thanks for your help

Check of the webcam module is loaded: https://wiki.archlinux.org/index.php/We … our_webcam
Can you access the webcam outside of zoneminder?

ale_arco · 2015-11-13 10:14:52

thanks for the quick response. The webcam is recognized correctly, I send you the response of the command lsmod - lsusb - dmesg for verification. I did not do the test to record the input for example with ffmpeg or else .... I do the test and let you know

regards

Does a /dev/vid* device exist?

Not an Installation issue, moving to NC...

Thank you all. I add information about the problem and try to answer to people. The WEBCAM is installed and connected to the system as /dev/video0. I run 3 commands, these are the result :

I think that the error is in the WEBCAM configuration, please send me yours opinions

try

mpv av://v4l2:/dev/video0

ale_arco · 2015-11-17 09:51:43

Hi c0mm0ner ....

I tried the command and this is the result:

# mpv av://v4l2:/dev/video0
Playing: av://v4l2:/dev/video0
[lavf] avformat_open_input() failed
Failed to recognize file format.


Exiting... (Errors when loading file)

I'm trying to find another webcam for the test, but I'd like to understand how to operate this philips. I trust in your or your knowledge of Linux to solve, so I will learn to manage WEBCAM

regards

Alessandro

What codecs does the cam support?

v4l2-ctl --list-formats

v4l2-ctl --list-formats-ext

ale_arco · 2015-11-17 14:15:09

Command Output :

# v4l2-ctl --list-formats

Thanks for the information. There seem to be some problems with gspca cams in (arch)linux. Maybe you are able to gather some information about possible solutions outside the forums?

ale_arco · 2015-11-18 13:10:06

He's trying for some time on various websites, for the moment nothing. Many people try to sort it out but leave surrendering. I will continue to try, if I find the solution placed on the site, in the meantime if you or others you have any idea of a possible solution, post it

Regards
