[SOLVED] 'zmc -d /dev/video0' crashed, signal 132 -- on ASUS Eee PC

Post by ksv »

Hello!
I have ZM installed on ASUS Eee PC 2G Surf with
Lubuntu 32-bit
I am trying to make ZM work with 640x480 USB camera, but it does not work. In ZM Console I see red circle at the Monitor-1 and source '/dev/video0' is red too. Here are the details:

Code: Select all

# lsb_release -a
No LSB modules are available.
Distributor ID:	Ubuntu
Description:	Ubuntu 18.04.4 LTS
Release:	18.04
Codename:	bionic
# uname -r
4.15.0-108-generic
I do not use internal EeePC drive, but instead boot from external hdd with 2 partitions one for the system and the rest for ZM

Code: Select all

# lsblk
NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda      8:0    0   1.9G  0 disk 
sdb      8:16   0 298.1G  0 disk 
├─sdb1   8:17   0  37.3G  0 part /
└─sdb2   8:18   0 260.9G  0 part /mnt/dvr
Memory (ZM works)

Code: Select all

# free -m
              total        used        free      shared  buff/cache   available
Mem:            418         194          13          12         209         199
Swap:          1765         154        1611
USB Camera works excellent with Cheese

Code: Select all

But ZM for some reasone do not work with it. Here is the beginning of the log from WEB interface

Disabling CPU_EXTENSIONS in (ZM - Options)->Config solved the problem.
Now Monitor-1 works as expected.

BTW: signal 132 means illegal instruction. My CPU does not support SSE3 instructions.
Thanks to Isaac Connor :-)
