GV800 16 CH shows the same image over all channels

Post by davists » Sun Sep 15, 2019 9:54 pm

Hi there,

I have tried a lot of configurations for my GV800 16 Channel (BT787a) to work alongside ubuntu 18.04 LTS and Zoneminder 1.32. I cant succeed streaming all channels same time on input1 (/dev/video0). Shows the same camera over all channels.
Please could you give me some advice?

GV800

/etc/modprobe.d/bttv.conf
# i2c
alias char-major-89 i2c-dev
options i2c-core i2c_debug=1
options i2c-algo-bit bit_test=1

# bttv
alias char-major-81 videodev
options bttv card=157,158,158,158 tuner=4,4,4,4 radio=0

Zoneminder > options
V4L_MULTI_BUFFER - unchecked
CAPTURES_PER_FRAME - empty

Monitor >Source
Capture Method - Video4Linux version 2
Device Format - NTSC
Multi Buffering - No
Captures Per Frame - 2

Final result: same channel over all otehrs.

You are better off using an IP Video Encoder instead of bttv cards.

See: https://wiki.zoneminder.com/Hardware_Co ... eo_Encoder

Used ones can be obtained for reasonable prices.
