saa7130 unstable video

[Bartosz Cisek]

Hello,

I have cheap Chinese noname card with 8 Philips 7130 chips, without
eeprom. It's dedicated to CCTV. Has no tv tuner, and I don't need sound. 

Card looks exacly like http://www.cn-dvr.net/products/enproducts76.html and AOP-8008A from
http://www.bttv-gallery.de/

I tried modprobe with all posible (1,154) card types, and tested each with "mplayer tv://". 
Some of them worked "a bit" but image was unstable and colors were substituted. It's hard 
to describe in detail so I grabbed a few seconds. Image quality is unacceptable for 
surveillance purpouse

http://bartoszcisek.pl/saa7130-sample2.avi (13MB)

My first thoughts were that there is a lack synchronisation, because image is shifted 
and moving. 

Card producer wrote that it has onboard x264 compression, maybe I use wrong codec for 
mplayer? I tryed x264 but it made only worse, there was no image at all. 

I've never done any linux driver coding. Can you please advise me how to start? maybe 
I don't have to code and it's just a matter of configuration?

Below I submit logs from lspci, dmesg and mplayer. Camera is OK as I checked it 
previously on bt878A card.

Thanks in advance for any hints,

regards

Bartek
