xawtv[SOLVED with a 'try every possible combination' script]

I seem to be making a name for myself with unsuccessful threads so I'll try and keep this one concise (failing already it would appear)...

wondering about all of this actually.

no plugins?
comes as a result of ebuild error regarding xine lib

ln -s /usr/lib/ /usr/lib/xawtv

fixed it for the time being

DGA support?. I imagine, whatever it is (Direct Graphics...Arse?) , is enable-able by commenting out that line in XF86Config

but isn't that disabled for a reason?
DGA appears to be an X extension that allows framebuffer access

I have v4l loading in the XFree86 config file

I had enabled bttv in the kernel which is why this also came as a bit of a shock

any ideas?

"operation not permitted" solved, obviously, by just logging in as root

thanks

I don't think you did anything wrong. I think the current ebuild puts things in the wrong places. See bugzilla.

Alternattivly, emerge 'tvtim' which works better and looks better and does work.

downloading tvtime right now

tvtime emerged, runs fine - just no channels to be seen

I tried running scantv but it scans right through everything without finding a station.

the card is obviously connected

the gist I've picked up is that modules.conf should be configured to include various bttv parameters and aliases but quite what is beyond me and

with dmesg not returning only

I am wondering if there is a greater problem

Let me show youwhat I have loaded, and I have not ever looked at modules.conf

bob@gentoo: pts/0: 5 files 108Kb -> su root

/home/bob
root@gentoo: pts/0: 5 files 108Kb -> lsmod
Module Size Used by Not tainted
ide-cd 33260 0 (autoclean)
tuner 10272 1 (autoclean)
tvaudio 14236 0 (autoclean) (unused)
msp3400 40044 1 (autoclean)
bttv 70720 1
i2c-algo-bit 9960 1 [bttv]
i2c-core 18312 0 [tuner tvaudio msp3400 bttv i2c-algo-bit]

My etc/modules.atoload looks like this:

# Add the names of modules that you'd like to load when the system
# starts into this file, one per line. Comments begin with # and
# are ignored. Read man modules.autoload for additional details.

# For example:
# 3c59x
bttv
msp3400
tvaudio
tuner

It sounds to me like your tuner is not running. Do an lsmod and see if it is loaded.

tuner

it's definetly loaded. it's also configured with

where 1 is supposed to denote PAL_I (alright for UK?) and the card=38 is for my tview99 card.

I rebooted...why didn't I reboot before?!

but problem is still unsolved

however, dmesg now spews out some interesting things related to my tvcard

detected

TView99

using

TView99

using tuner=-1

MSP34xx

not found

[Philips PAL_I (FI1246 and compat] registered to adapter [bt8 48 #0](pos. 0).

it appears to be detecting my card, then using my specified card type (which matches the detection) but then using tuner=-1 instead of one but then assosciating the correct tuner later on (PAL_I [=1]).

msp34000 is definetly loaded so I am unsure as to why it isn't found

clutching at straws here...HELP!

oh, just noticed

in dmesg

mean anything to anyone?

I took me a bit of trial and error for this, as well as some googling:

http://www.mind.lu/~yg/ftvco/

The above info helped, although the script would not run right for me. However, I tried the same method as the script (by hand) until I got things working; actually not *that* difficult...

Here's my setup:

In /etc/modules.d/aliases, I removed the bttv and i2c stuff

# moved to /etc/modules.d/bttv
#alias char-major-81 bttv

# Support for i2c and lm_sensors
# moved to /etc/modules.d/bttv
#alias char-major-89 i2c-dev

In /etc/modules.d I made a bttv file:

# I still don't know what the f#*king values should be, so I'm just
# trying sh*t to see if it works.

# i2c stuff
alias char-major-89 i2c-dev
options i2c-core i2c_debug=1
options i2c-algo-bit bit_test=1
#options i2c verbose=1 scan=1 i2c_debug=1

# bttv stuff
alias char-major-81 videodev
alias char-major-81-0 bttv
alias char-major-81-1 bttv
options tuner type=2 debug=1
options bttv card=2 pll=0 radio=1
options msp3400 once=1 simple=1
post-install bttv modprobe tuner; modprobe videodev

And then in /etc/modules.autoload, I added:

# I'll try the modules.d/bttv method
tuner
bttv
videodev
tvaudio
tvmixer

It seems like these things are very finicky about certain settings, and the module load order. But if you keep trying different options, it *should* work...

AFAICT, the PAL vs. NTSC is not a tuner option, but rather a setting in your ~/.xawtv file (or other tv app config). Here is my ~/.xawtv file:

sarnold, you are THE MAN.

that script you found trying all the possible combinations for the first time gave me something other than fuzz.

I then hooked my graphics card up to my multi mega (megadrive/mega cd hybrid [known as the cdx in the states]) as I knew the frequency of that connection (I love all sega things of the megadrive/genesis era). eventually I got a viewable picture

viewable enough to complete stage 1 and 2 of sonic 2 but not quite act 2 yet

a few options later and much fiddling with the settings I managed to get colour as well, and remove the 3 ghost images. The picture is by no means perfect and my picture from my digital top box suck boaby but the terrestrial picture is perfectly watchable.

I'm not questioning the radio=1 option. It works with it, so I'll leave it alone.

thankyou everyone in the #gentoo channel, you were most helpful. This has been one of my longest running problems.
