Kodicom 8800 starting to go crazy

[matteo_galet]

Hello,
I had to format my Zoneminder DVR server because of a broken hard disk.
I reinstalled everything based on a Ubuntu 15.10 server with Webmin, and applied the i2c fix for the card to speed up recognition on boot.
The strange thing is I get a very distorted image from cameras (I got 4 PAL cameras connected and 4 inputs unused).
It used to work fine once upon a time...
Here is a picture to get the idea:


This is the acquisition card I have:

Code: Select all

04:08.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11)
04:08.1 Multimedia controller: Brooktree Corporation Bt878 Audio Capture (rev 11)
04:09.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11)
04:09.1 Multimedia controller: Brooktree Corporation Bt878 Audio Capture (rev 11)
04:0a.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11)
04:0a.1 Multimedia controller: Brooktree Corporation Bt878 Audio Capture (rev 11)

04:0f.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11)
04:0f.1 Multimedia controller: Brooktree Corporation Bt878 Audio Capture (rev 11)

Here it is my /etc/modprobe.d/bttv.conf :

Code: Select all

options i2c-algo-bit bit_test=1
options bttv gbuffers=8 card=102,102,102,102,102,102,102,102 tuner=4,4,4,4,4,4,4,4 radio=0,0,0,0,0,0,0,0 i2c_hw=1 chroma_agc=1 full_luma_range=1 coring=1

And finally, my monitor config:


Do you have any idea what could be causing the issue?

Thanks!

Hi,

Do you have Options::Config::V4L_MULTI_BUFFER checked? If not, check it and set CAPTURES_PER_FRAME to 1. Post results.
In your monitor, play with the multibuffering too.

Hope it helps,
