mitchell7man · 03-18-2010, 08:42 PM

OS of this system: Ubuntu 9.10 Server

Okay so i have a Hauppage card, not sure exactly which one, under lspci it is:

when i bring up xawtv i get a blank screen, i figure its because it doesn't know what channels to read or whatever, so i run scantv:

Code:

input = Television
norm = NTSC

vbi: open failed [/dev/vbi]
open /dev/vbi: No such file or directory

How do I go about getting this working? --I'm trying to make sure the card works before I mess with myth-setup anymore.

Note: in MythTV I don't get the "Scan Channels" option, so I'm not sure what to do there.
Note: Cable source is my college campus cable.
Thanks,

Run "ls /dev/v*". I've got a Hauppauge bt878 based card and I have /dev/video0 and /dev/vbi0. It's hard to look at your lsmod output, but it looks like it's probably OK. It would be better to see the results of both "lsmod |sort" and "dmesg |grep bt".

Try the program "tvtime". That's what I use in mine.

I'm trying TVTime now...

Okay, so same problem with tv time, no "station file".

Thank you for using tvtime.

Quakeboy02 · 03-18-2010, 09:05 PM

I don't know what this means, but the rest looks OK.

Code:

[ 10.236246] bttv0: audio absent, no audio device found!

Quakeboy02 · 03-18-2010, 09:07 PM

I suspect that a big part of your problem is that you're logged in as root. Is there some reason for that? Try logging in as a regular user. Root is not for user applications.

Code:

root@kate:/dev# tvtime
...
I/O warning : failed to load external entity "/root/.tvtime/tvtime.xml"

mitchell7man · 03-18-2010, 09:07 PM

the card has "audio out" I have a 3.5mm cable going from the output to my sound in. --- What do I do about the "station"/channel file?

mitchell7man · 03-18-2010, 09:18 PM

My server is in a closet here, i'm forwarding x through ssh. (ssh -C -X). Anyhow, as a normal user:

Code:

You'll have to deal with this the way you usually deal with running X remotely. Something like xawtv --display server:0.0. I dunno. I haven't dealt with remote-X in many many years.

Code:

v4l-conf had some trouble, trying to continue anyway
v4l2: open /dev/video0: Permission denied

What is the result of "ls -l /dev/video0"? Is your userid, on the machine with the board, a member of the "video" group?

mitchell7man · 03-18-2010, 09:49 PM

I just added my user to group "Video" (usermod -G video mitchj). This is my current output for ls -l /dev/video0

Quote:

mitchj@kate:~$ ls -l /dev/video0
crw-rw---- 1 root video 81, 0 2010-03-18 20:46 /dev/video0

The display comes up fine when I'm logged in as root.

Quakeboy02 · 03-18-2010, 10:09 PM

So are you getting a different set of error messages now? If so, what are they?

mitchell7man · 03-18-2010, 10:14 PM

i'm still getting the same errors

Quakeboy02 · 03-18-2010, 10:17 PM

Then are you sure you set the permissions on the right machine for the right user?

Thats all on the right machine. Wow, I do not know whats up with this...

mitchell7man · 03-19-2010, 03:03 AM

I got the card working, I installed firmware from http://www.linuxtv.org/wiki/index.ph...WinTV-HVR-4000 and I got reads immediately after.

Now I'm working on setting up mythtv. What type of input is this? When I try to scan for channels, i get failed to start device or something along those lines.

-Thanks for your help.
