 Posted: Sun Mar 20, 2005 4:40 pm Post subject: Kernel choice with MythTV |
 |
|
Hi.
I just did a Stage2 install, and i'm at the point where I need to choose the kernel.
I've read plenty of guides on howto setup a Gentoobox with mythtv,
but most of them are somewhat outdated.
Any suggestion on what kernel to choose?
Reading here, http://home.comcast.net/~alf_park/mythtv.html, "The gentoo-dev-sources already contains the lirc/lirc-i2c patches which is a blessing in disguise",
is that still the case with newer gentoo-dev-sources kernels?
Now, this box wont be a fullblown htpc, I guess I mostly want to be able to set up my recordings via mythweb and view them later on other machines.
But still it would be nice to be able to use the remote.
This is a P3-600 box with a PVR-250, Voodoo5 + 3 disks. (15gb, 150gb, 200gb)
Any advice would be most helpful.
Thanks.
Edit:
http://gentoo-wiki.com/HARDWARE_Setup_MythTV
"Note: As of December 2004 and Kernel 2.6.9, the LIRC patch is no longer included in either the Gentoo or Love sources. What finally worked for me were the plain-old, unpatched, vanilla 2.6.9 sources (emerge development-sources)"
http://dev.gentoo.org/~cardoe/mythtv/
"Warning: Please select a 2.6 kernel, preferably gentoo-dev-sources."
So what's left is development-sources??
Edit2:
Or can I emerge gentoo-dev-sources and then emerge lirc, and that will work? (that will save me time as I want fbsplash too) |

gentoo-dev-sources should work fine.

| You don't need anything special -- just V4L support and support for your specific TV hardware. All are in the default kernel sources, so I suggest gentoo-dev-sources. |

Thanks.
I emerged gentoo-dev-sources and I think I enabled all the necessary stuff in the kernel.

I was having trouble getting LIRC and IVTV to work with anything above kernel 2.6.5. I tried all sorts of flavors, including gentoo-dev-sources, so your mileage may vary. Good luck, and let me know if you get it working!
I'm still having a problem where I cant tune to channels above ~60 under linux. Everything tunes fine and is crystal clear under windows.

That should be OK, however I am not familliar with the PVR-250 so I don't know if the BT848 driver is the correct driver -- but I assume you've done your research. |

That doesnt sound very promising. Oh well, we shall see.
| Quote: | | Good luck, and let me know if you get it working! |
Sure, no problem 
I will continue as soon as it's done compiling. (i emerged "evilwm kdebase mplayer" and it's been at it for 9hours+ now)

Lucky me then.  I'm in Sweden and my channels don't go that high. (Now anyway since I cancelled my ComHem subscription.)

Well, to be honest i don't know either. I followed a guide, + I could'nt see anything other related to PVR-250 under "Video For Linux". |

| PVR-250 requires the ivtv driver. It is in portage. |

Jepp.. Thats on my "todo-list" after the current compiling is done.
From the guide:
| Quote: | | ivtv is masked but available in portage. The better solution, however, is to use the latest stable version which is (as of 2004-11-04) ivtv-0.2.0-rc2l. |
I'm thinking of going that route instead. If thats unessesary please tell me. |

For those who wanted an update..
All is now compiled (mysql, mythtv 0.17 etc.)
* I had to download/compile latest xmltv to get it to work with mythtv. (Remember: Sweden here)
* I downloaded "ivtv-0.2.0-rc3i" (latest stable) and compiled it myself.
Current Status:
* The remote works.
* No picture on the pvr-250.

And the result is a black picture.
Emerged both xawtv & tvtime.
scantv finds nothing.
So there I am now, thinking of what to do next.  |

Check your tuner type... The company pulled a switch-o without changing the version of the card, and some newer PVR-250's have a totally different tuner chip!
| Code: | alias char-major-81 videodev
alias char-major-81-0 ivtv
options ivtv ivtv-debug=0 mpg_buffers=90
options tuner type=39
options msp3400 once=1 simple=1 debug=0
add below ivtv msp3400 saa7115 tuner
|
That's mine, tuner=39.
I spent a good few days with tuner=2 before switching that and viola it worked. Could be your case as well. |

Alright, changed tuner type to 29.. I assume thats correct since it reports that in dmesg (ivtv section).
Do xawtv work with pvr-250?
After I changed tunertype I rebooted and ran scantv.. still found nothing.
tvtime refuses to function. Can't even enter the "Change video source" in the "Setup - Input configuration".
But everything looks alright, the dmesg output, I can change the cards setting via ivtvctl and it accepts it. hmmm.

It's working 
Final check is to see if i got sound in my scheduled recording. (I'ts flagging commercials right now, and then of to transcoding)
I was totally blown away by MythWeb. Truly beautiful. 
Edit: ok, more job to be done.
* No sound (*** Solved)
* transcoding failed (log states: 2005-03-23 08:41:04.161 Unknown video codec:) (*** Solved)
Any pointers?
Edit: All good. Everything is working now. |

Thanks for posting the config.
You said you wrre getting an error - which you solved:
| Code: |
modprobe: FATAL: Error inserting bttv (/lib/modules/2.6.11-gentoo-r4/kernel/drivers/media/video/bttv.ko): Unknown symbol in module, or unknown paramenter (see dmesg)
|
I get a similar error but not for bttv but ivtv.
How did you solve?
| Code: |
#
# Digital Video Broadcasting Devices
#
# CONFIG_DVB is not set
CONFIG_VIDEO_TUNER=m
CONFIG_VIDEO_BUF=m
CONFIG_VIDEO_BTCX=m
CONFIG_VIDEO_IR=m
CONFIG_VIDEO_TVEEPROM=m
|
[/code]
Also, the above? Can;t seem to find it.
Is it crucial - where is it configured in the kernel I couldn't seem to find the options.
IS it under the Video for Linux kernel options? |

Well, I played around with the settings in /etc/modules.d/ivtv until it worked.

alias char-major-81-0 ivtv
alias char-major-61 lirc_i2c

#From Wilsonet
#options ivtv tda9887=0
#options ivtv ivtv_std=2 tda9887=0
#add below ivtv msp3400 saa7115 tuner
add above ivtv lirc_dev lirc_i2c |
Thats what I use now. The box has been up for 24 days and not one problem.
Your modprobe error could perhaps be order related? (and check dmesg)
About that DVB problem:
Last time I saw them were under Device drivers ---> Multimedia devices --> Digital Video Broadcasting Devices.
Though, I'm looking there now, and they're gone.
Perhaps I've updated my kernel since the first installed version and just copied over the .config. I honestly can't remember.
If you're using a pvr-250/350 you don't need DVB.
A few days ago I even upgraded to the latest mythtv 0.18.
Not a single problem so far. |

irtv and lirc are working nicely now.
Seems as though I needed to set allow module unloading. Not sure though - never mind.
BTW did you upgrade to Mythtv 0.18 using portage? There's no ebuild in my portage tree - maybe I'll sync... |

I just checked and I have "module unloading" activated.
| Code: | ---->Loadable module support
[*] Enable loadable module support
[*] Module unloading
[*] Automatic kernel module unloading |
Strange.
Anyhow, to get Mythtv 0.18 i found some ebuilds and added them myself.
But I see that 0.18 is hardmasked now, so just unmask them and see if that works. |
