[SOLVED] Problems with BTTV on 14.04

Post by haus » Fri May 02, 2014 11:31 pm

Hi all,

My ZM box has been humming along nicely for years until a recent heat wave caused total and sudden hard drive failure. As a result, I've decided to start from scratch and rebuild on Ubuntu server 14.04. I've got ZM up and running using this guide (http://www.zoneminder.com/wiki/index.ph ... e_easy_way) but I can't get any of my analog camera video sources to work.

I have a Kodicomm clone and another one of those cheap 4-in-1 cards, and they have always worked with:

Code: Select all

options i2c-algo-bit bit_test=1
options bttv card=102,102,102,102,102,102,102,102,77 tuner=4,4,4,4,4,4,4,4,4 gbuffers=32 chroma_agc=1
in /etc/modprobe.d/options.

Now, no matter what I do, dmesg | grep bttv reports:

Code: Select all

[  312.628183] bttv: 8: Bt878 (rev 17) at 0000:04:0f.0, irq: 16, latency: 64, mmio: 0xfdff1000
[  312.628204] bttv: 8: using:  *** UNKNOWN/GENERIC ***  [card=0,autodetected]
[  319.060022] bttv: 8: tuner type unset
[  319.060187] bttv: 8: registered device video8
[  319.060241] bttv: 8: registered device vbi8
It's like it doesn't see the card types I am trying to define. /dev/videoX (0-8) is red in the ZM interface. Since it has been a very long time since I set up bttv on Ubuntu, I'm wondering if there is something that has changed significantly in recent years that I'm not finding via searches?

Ok, replying to myself, I sort of got it working. I put "bt878" in /etc/modules and put:

Code: Select all

options bttv card=102,102,102,102,102,102,102,102 tuner=4,4,4,4,4,4,4,4 gbuffers=32 chroma_agc=1
in /etc/modprobe.d/bttv.conf

and now I get some video (orange sources in console though) and this dmesg:

Code: Select all

 [  412.376089] bttv: 7: Bt878 (rev 17) at 0000:04:0f.0, irq: 16, latency: 64, mmio: 0xfdff1000
[  412.376117] bttv: 7: using: IVC-200 [card=102,insmod option]
[  412.376343] bttv: 7: tuner absent
[  412.376400] bttv: 7: Setting PLL: 28636363 => 35468950 (needs up to 100ms)
[  412.408049] bttv: PLL set ok
[  412.408162] bttv: 7: registered device video7
[  412.408934] bttv: 7: registered device vbi7
I'll continue futzing and report back whatever seems to work, assuming I make more progress.

Edit: Silly me, sources are orange in monitor mode, and green in modect, so I think this is working as expected now.

Final config has this in /etc/modprobe.d/bttv.conf:

Code: Select all

options i2c-algo-bit bit_test=1
options bttv card=77,102,102,102,102,102,102,102,102 tuner=4,4,4,4,4,4,4,4 gbuffers=32 chroma_agc=1
and "bt878" in /etc/modules.

Working beautifully.
