 Posted: Fri Feb 20, 2004 6:30 am Post subject: Would like help getting bttv working! |
 |
|
I recently purchased a Shuttle SB75G2, P4-2.8GHz, 1GB RAM, 250GB HD, and a Hauppauge PVR-350. I have gentoo installed and finally am working on the mythtv install. Actually, and I don't know if this is bad at this point, I have mythtv completely installed, but there is one problem...
I can't get bttv.o to load! Where to begin:
Kernel setup:
| Code: | <M> I2C Support
<M> I2C bit-banging interfaces
<M> I2C PCF 8584 interfaces (anything definitive on if I really need this?)
<M> I2C device interface
<M> I2C /proc interface
...
<M> Video For Linux
[*] V4L information in proc filesystem (does it matter that it isn't a module?
<M> BT848 Video For Linux |
To my knowledge (after reading as many posts as I can on the subject) this is all that's required to get it to work. I'm running 2.4.22.gentoo-r5 sources.

insmod bttv:

/lib/modules/2.4.22-gentoo-r5/kernel/drivers/media/video/bttv.o: init_module: No such device
Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.
You may find more information in syslog or the output from dmesg |
(in case it matters)
insmod videodev:
| Code: | Using /lib/modules/2.4.22-gentoo-r5/kernel/drivers/media/video/videodev.o
/lib/modules/2.4.22-gentoo-r5/kernel/drivers/media/video/videodev.o: init_module: Input/output error
Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.
You may find more information in syslog or the output from dmesg |
I'm not sure what 'syslog' is referring to, but I don't see any log files that specifically mentioning bttv failing to load.
I'm at my wits end! Could anyone please help out? Let me know if I should post anything else about my setup.
Thanks!

Maybe you can post your dmesg output, after loading the bttv module via insmod.
Although I'm not sure, my guess would be, that your card does not have a bt848 chip.

Hi, i'm trying to setup mythtv at the moment too, but i keep getting kernel errors and ooops all the bloodly time on my nforce2 board. i have apic acpi and preemptive all disabled but still i seems to happen every now and then. i'm only just compiling xfree.
anyway back to you since you have a pvr-350 and don't need bttv you need the drivers from IvyTV project http://ivtv.sourceforge.net/
I have a bttv card so i can't help you set it up so good luck.

Mondauge, thanks for the info, when I get home, I'll dmesg and see what I come up with. I know it fails, and I have checked my dmesg but didn't find anything helpful before. And you know, I just always assumed it was a BT848 because I thought it was just a PVR-250 with a little extra power. However, I'll do some more research and see if I do indeed need anything else.
Jimill, thanks, that gives me other things to think about. I'll check out the link and read what I can for some answers.

W00T! I've got something finally going here. I believed that I had to have the bttv driver working, but I was just plain wrong. So I went to where you had suggested, which I initally read a few days ago and thought I needed bttv first, and I went through the whole procedure.
Next I emerged mplayer and after fiddling with the actual input number, mine ended up being 4 (test_ioctl -p 4), I actually saw video and heard sound. Oh frabjous day!
Now, I completed my mythtv backend setup, ran mythtvbackend, then ran mythtv.
In the shell where I ran mythtvbackend, I saw this:
| Code: | bash-2.05b# mythbackend
Starting up as the master server.

Any further ideas on this? I don't know why it mentions OSS when everything I've read (yeah, I know, everything I've read before has been wrong before!) I am supposed to be using ALSA and not touching OSS. In case it matter, I did indeed leave mythsetup at the default value of /dev/dsp for the audio.
I went back to the mythtv docs and looked up stuff on segfaults and I was a bit frightened because they mentioned recompiling in debug mode and executing it gdb. I really don't think I'm prepared for something like that yet!

Jimill,
Concerning your problem with compiling X, if you haven't resolved your issue yet, have you tried running memtest86+ on your machine? I recently spent a whole weekend setting up my new machine and had many compile problems. It ended up that, after running memtest86+, I had some seriously bad memory. I was highly disappointed since it was an expensive, matched pair of high-end Corsair memory. I've since sent it back and am praying I get a replacement (because the temp receptionist at my company may not have enough neurons to follow directions!)
Anyway, you can grab memtest86+ here: http://www.memtest.org/
