MythTV Setup Guide/HOWTO

50cc:

Try running mythfrontend from a terminal. When you are playing livetv and getting a black screen, check the output in the terminal.

Coleslaw:

I couldn't get the ivtv ebuild to work until r3. It compiles fine and so far I have no complaints. (Just rebuilt my box last week)

Anyone else:

Where did all the patches go at http://dl.bytesex.org/patches/ ? All I see now is the patches for 2.6.5.

I tried emerging it, and I wanted to let everybody know, it didn't work for me. I used Chris Kennedy's IVTV Patches (ivtv-0.1.10-pre2-ck33.tgz in particular) and that got my video working for me when I watch live tv.

If Mythtv starts recording though, all it records is a blank screen and then afterwards when I try to watch live tv again I have to use the commands from the howto

I've updated the guide to include MythWeb now. Also, I'm planning on upgrading the kernel/ivtv soon so watch for an update on that.

Great guide!

I've added a link to it in the install guides section of the PVRHWDB, hope you don't mind

Does anyone have the 2.6.3 kraxel patch? It seems to have disappeared. I would like to use the kernel in the guide just to make sure I do not make any dumb mistakes.

Thanks

Where can I get the ivtv patch for kernel version 2.6.5? (lison.com only has upto 2.6.3) and which ver of ivtv driver should I get?

Did you get the kraxel patch to work for 2.6.5? When I patched it the BT846 option didn't appear under v4l

I have been struggling with 2.6.5 and mythtv for about 1 week. I can run the (mythtv 0.14-r1) mythbackend now (with an authorization error at the start) and I can start the frontend, but when I go to live TV, I get a message about Xv not being supported. I have a Hauppauge PVR-250 card with hardware encoding, and I think this is what is not being supported. I am assuming that this is due to the fact that I have not patched the IVTV 0.1.9-r3 source.

I cannot find a patch for the 2.6.5 kernel either. (www.lison.com/ivtv.patches) seems to have patches up to and including 2.6.4, but no 2.6.5.

any idea on where I can get a patch would be appreciated. And, of course, if anyone has another idea of what might be wrong, I would like to hear it.

lastly, I can run LIRC and using irw, I can get the correct codes for my remote. Problem is, when I run winfrontend, nothing (remotely) works. Please help.

Using some of the ck's ivtv patches, I haven't needed the lison patches. I used ivtv-0.1.10-pre2-ck26 and 2.6.1 for weeks with no trouble. I'm currently trying to get ivtv-0.1.10-pre2-ck67c working with 2.6.5.

I guess that depends on your definition of work :-)

I just did a normal kernel compile, rebooted, then went to my ivtv/drivers/ directory and did a make && make install.

Everything works fine, except changing the channel has no effect. i.e. after myth pauses, records 2 seconds of video and starts playing back, you're on the same channel you were before.

Only certain ck patches are stable. You'd have to read the mailing list to find out which ones are. 67c is supposed to be one, 26 is another. I've found that 67c's hardware decoding doesn't look as good as 26's, so I went back to that one. There are a few other stable versions, but I didn't try them because 26 worked.

The channel change bug is in the kernel, not ivtv. I'm going to try a vanilla 2.6.5 instead of gentoo-dev tonight when I get home.

What does the patch actually do? Will the later versions of ivtv work?

On a different note, would knoppmyth be any easier. ;-)

EDIT: Nope, got almost everything working with Gentoo and am glad that I didn't switch to knoppmyth. ;-)

ok, I am trying to compile the CVS version of MythTV. I keep getting the following error:

cayenne · l33t Joined: 17 Oct 2002 Posts: 945 Location: New Orleans

Hello,
I'm about to get started on this project...I see in gentoo-dev-sources there is available:

gentoo-dev-sources-2.6.5-r1.ebuild
gentoo-dev-sources-2.6.5.ebuild

At the bytesex site for the patches they list:
2.6.5-1/

Does it matter if I use the -r1 kernel available for Gentoo..or do I stay with the 2.6.5 version? I'm a little confused on the numbering systems for the patch and kernel, and I've read they need to match exactly....

Thanks in advance for help!!

cayenne

hey everybody

I've been pouring through the forums and all the documentation and I think I'm almost there in settuing up my PVR box, but I could use some help (btw, it's in an Xbox BOX, ,I'll post pictures when I'm done =-}

I'm running 2.6.5-gentoo-r1. I emerged everything that's needed and I can get the mythbackend to run and the mythfrontend as well. For the most part things seem fine. I've emerged the ivtv ebuild and lirc (I just put in a hau. pvr-350 card). Two things though:

1. When I run "mythfilldatabase" I keep getting: (sorry, silly question, I guess everybody has been getting this, right?)

yoda34 · Tux's lil' helper Joined: 10 Jul 2003 Posts: 93

The zap2it error on mythfill is a known problem and should be fixed with version .15 (which came out like an hour ago on mythtv.org). so hopefully we will get an ebuild pretty quickly.

As for the other problem of blank screen and myth locking up I had the same problem with my pvr 350 card. A few things

1. Make sure you can capture video/audio by cat /dev/video0 > test.mpg

2. in the mythfrontend go to setup->tv->playback(i think) and make sure you have the box that says use pvr 350 tv out checked.

3. I have to set the pvr 350 tv out device every time I boot or myth wont' work(i put it in a boot script)
test_ioctl -d /dev/video16 -u 0x3000

also make sure your frambuffer is working also.

Hopefully I helped a little

Andy

Make sure you have you actually have a /dev/fb0

if so you need to configure your X Free config file to use the ivtv framebuffer.

once you do that hook up your 350 out to your tv and start X. Your X session

should show up on your tv. If your desktop is there then you know the

framebuffer is working. Have you gotten that far? I can post my ivtv module

file and my X free config file if it would help
