Hello,
I have a working IVTV device (Hauppauge PVR 150) and a USB DVB device. Both devices are properly installed.
| Code: |
htpc ~ # dmesg | grep -i ivtv

| Code: |
htpc ~ # dmesg | grep -i dvb
dvb-usb: found a 'ITEtech USB2.0 DVB-T Recevier' in warm state.
dvb-usb: will pass the complete MPEG2 transport stream to the software demuxer.

|
But I can't find any of those cards in mythtv-setup -> Capture card setup -> Card type.
(I have a Mythbuntu installation on the same machine and it works without any issues.)
Please help me to fix this issue.
Also,
I reseved the below error message while starting mythbackend service.
| Code: |
htpc ~ # /etc/init.d/mythbackend start
* Starting MythTV Backend ...
* WARNING: -c/--chuid is deprecated and will be removed in the future, please use -u/--user instead [ ok ]
htpc ~ # /etc/init.d/mythbackend status

Thanks in advance. |

Have you run through mythtv-setup yet? It sounds almost as if Mythbuntu does this for you. Gentoo doesn't, you have to do initial setup and configuration yourself. There's a pretty decent wiki for it at the MythTV site.

Yes, but those device types are not listed under Capture card setup -> Card type in mythtv-setup. |

Here is the output.
| Code: |
htpc@htpc ~ $ emerge -pv mythtv
These are the packages that would be merged, in order:

Thank you Jaglover,
I added dvb, v4l, ivtv and all the use flags listed in http://en.gentoo-wiki.com/wiki/MythTV and updated the system (emerge --update --deep --newuse world).
Now the DVB card is working  . But the IVTV card still is not available in the list (mythtv-setup -> Capture card setup -> Card type).
I have noticed the below output while emerging mythtv package.

I don't know if this is relevant, but there has been some stuff going on, with deprecating v4l in favor of v4l2. For a long time the 2 versions coexisted, then I believe v4l became a backwards-compatible shim on top of v4l2. I believe some time back they decided the original v4l needed to die, but have no idea of the timeline.
As for your IVTV card, it's possible that you're seeing what I see. I have the hvr-1600, which is has hardware mpeg like the pvr-x50 cards. When I run mythtv-setup it isn't autodetected - instead it autodetects a regular analog card, which is incorrect. I have to manually select the card type, and at this point I don't remember if that's IVTV or if there's something more specific to my card. Once I select an appropriate card type, it autodetects my hvr-1600 and properly identifies it.

All I can say is I haven't had much luck with older IVTV cards myself, in fact I tossed my PVR-250 because I was unable to get it working in MythTV, I obtained a 2250 only to learn it does not work in 0.25. Luckily enough it works fine in 0.24.2. 
The only advice I can give at this time is try 0.24.2, there are several bugs filed and some of them are addressed and fixed.

What???? Dang, I was going to update everything today. I'm still on .23.
I had to reformat the server, and I forgot to backup the mythtv database. Sigh...
Did you figure out why the 2250 doesn't work? |

If you are interested in digital reception then you are OK, I still have my analog cable and analog + 2250 + mythtv-0.25 = failure. Although I haven't tried lately. Maybe latest 0.25-beta works.
Here's my history with analog and MythTV:
0.22 - everything analog works
0.23 - framegrabber V4L card stopped working, replaced it with PVR-250
0.24 - PVR-250 stopped working, replaced it with 2250
0.25 - last time I tried it nothing analog worked
... go figure ...

Ah, we have no analog channels here any more. They stopped broadcasting analog last August.
I don't think I'm going to be able to update, the ew-mythtv overlay just hangs emerge. Don't know what's going on there. It also complains about sets not existing. |

I suspect I may be having this issue as well. I have a USB tuner card (KWorld USB ATSC TV Stick UB435-Q V3) that I know is operational under Gentoo, since I've been able to tune some stations through it under VLC. But the tuner is not selectable under mythtv-setup. Further, I have a problem recompiling MythTV: I switched my profile to no-multilib, and after having done so MythTV compiling fails (I think there is some bug in the no-multilib set-up). In order to find out whether it is the USE="-dvb" that is causing me to be unable to add my tuner, is there a way I can check what are the USE= flags for the currently-installed version of MythTV on this system? Just to clarify further, the version Of MythTV on this system was compiled and installed before I changed my profile to no-multilib. Thanks |

To see the USE flags for the currently compiled version use:
| Code: |
$ equery uses mythtv
|
That's part of the gentoolkit package.
Also, you need the dvb USE flag if you want to use any sort of digital tuner:
| Code: |
$ equery uses mythtv
[ Legend : U - final flag setting for installation]
[ : I - package is installed with flag ]
[ Colors : set, unset ]
* Found these USE flags for media-tv/mythtv-0.27.4_p20150124:
U I
- - dvb : Enables support for Linux DVB cards. These include all cards that work with digital signals such as ATSC, DVB-T, DVB-C, and DVB-S, QAM-64, and QAM-256.
|
I don't have it set here as this is my frontend, however, my backend needs this flag set. |

Thanks for your input, danomac. I get when I run that.
To my untrained eye, that looks to be indicating that dvb is called for in my make.conf, but that the package hasn't been compiled with this flag set. Sound right? And, in any case, doesn't this look to be the nature of my problem with the KWorld USB ATSC TV Stick being unavailable for selection in mythtv-setup? If so, I'm kind of at a loss as to what to do. In theory I'd have to submit a bug report--which is something I have only a very vague idea about how to do--then wait until some fix is applied. Or else ask someone more knowledgeable whether they can think of a workaround. Ugh. |

According to that your configuration wants to build dvb support, but your currently installed mythtv doesn't have that support. This is the cause of your problems as it's a digital ATSC tuner. You need that support for both pci[-e]/usb tuners.
What's the last bit of output of the mythtv emerge? Maybe we can track down why the build is failing. We'd need the last bit of the build log as well, not just the output of emerge. There'll be an error in there somewhere that should be visible. |

I've tried compiling MythTV at least twice more since then but continue getting failures. The only interesting thing is that it seems it's not always failing at not finding the same file/directory: in this case it is va_x11.h but I've seen another, similar file name that, I think, had glx in the name. If you could provide any advice on how to resolve this and get MythTv to recompile, I'd be most grateful.

OK, I have two instances of these files, and both belong to x11-libs/libva:
| Code: |

Have you tried rebuilding that specific package?
| Code: |
$ emerge -a1 x11-libs/libva
|
Also, are you using ffmpeg or libav? To search use `equery list ffmpeg` and `equery list libav`. You should get output for one of them. It's possible there's a conflict there too. |

Yes. At least twice.

Well, mythtv uses its own internal copy of ffmpeg before the ffmpeg/libav split happened. However, sometimes gentoo changes packages to use shared libraries, and I don't know if mythtv is one of them. libav is not exactly compatible with ffmpeg, and it can cause problems. I doubt that this problem you're having is related.
I've had pretty much no luck with libav and so I've binned it (as have many others). If you want to disable it, set your USE flags to include "ffmpeg -libav" and hopefully portage will sort out the ensuing mess. I just read that ffmpeg is going back to being the default in gentoo anyway.
I see in your other thread that you've switched profiles, have you done a:
| Code: |
$ emerge -pvuDN world
|
To see what the changes are? I don't know that `emerge -e world` will build in support for new USE flags (as evidenced by the output you've shown me.)
When you get the results you can post them here.
After that, they can be emerged:
| Code: |
$ emerge -uDN --keep-going world
|
The "--keep-going" flag will remove a failed package from the build list and continue on if there's problems. |

Ok. I'll hold off on doing that for a moment--gotta step away for a few hrs. Maybe I'll go ahead and start the process before I leave, though. |

(emphasis in the build log is mine)
Ahem, I stand corrected. Apparently it is using the shared libraries, and at this point I'm willing to bet libav is the problem. Remember the incompatibility of libav I mentioned in one of my earlier posts? I myself have had issues of some packages not building against libav, which is why I binned it a long time ago. One of the things libav doesn't do is stay ABI/API compatible with ffmpeg and that can cause issues like these.
In your /etc/portage/make.conf and these two USE flags to the existing ones: "-libav ffmpeg" (or change them if they are there already.)
Then try a:
| Code: |
$ emerge -pvuDN world
|
It's possible that portage is going to have some blockers, libav can cause a big mess. If you get no errors you can build the updates, if you do, post them here and we'll try to resolve them.
I'll bet when you changed profiles it forced a switch from ffmpeg to libav, and this change caused mythtv to stop building. Just speculating here.
Edit: What profile did you switch to? MythTV is being built without ALSA support, i.e. you won't have any sound... |

Thanks for the additional input, danomac. I feel like I'm learning some things. Had to take a day off from this to attend a funeral, but I'm having another go at it now that I'm back.
I did end up running emerge -uDN --keep-going world as you had suggested, letting it run in a terminal til I returned. But, as expected, MythTV failed to compile again. Here's a bit of output I keep seeing that may (or may not) shed further light on what's at issue here: | Code: | !!! existing preserved libs:
>>> package: x11-libs/libva-1.3.1
* - /usr/lib64/libva-glx.so.1
* - /usr/lib64/libva-glx.so.1.3501.0
* used by /usr/lib64/libmythtv-0.27.so.0.27.0 (media-tv/mythtv-0.27_p20140321)
Use emerge @preserved-rebuild to rebuild packages using these libraries |
No errors appear when, after I've put in the ffmpeg and -libav flags, I run emerge -pvuDN world and look at terminal output. By that I mean that I am just told what is going to be built and am shown a list of use flags for each, in varying colors. All looks to be in order in my rather inexpert opinion. So I think I'll give the real thing another go.
As mentioned, I switched to no-miltilib (from Desktop). On reflection, that was probably a mistake. I was initially confused by the options and chose desktop, then decided that was probably a mistake and switched to no-multilib. Having subsequently done more administration and read a bit more about Gentoo, I realize I probably should not have switched to no-mulitlib. But this is a dedicated machine--its only function being to run MythTV--so I'm hoping I'll be able to make things work as the process for switching back to Desktop is unsupported and rather convoluted.
Yes, I too noted the issue with ALSA and realized it could cause me problems. I therefore set ALSA in my USE flags prior to my last emerge -uDN --keep-going world (completed one day ago).
Fingers crossed . . . |

What that is telling you is package x11-libs/libva has been upgraded, and the version of mythtv that is installed is still using the old version that's no longer available. So it wants you to install mythtv again to compile again to the new libraries.

It's very possible that ffmpeg was on your machine originally when you compiled mythtv. Let's hope that's all it is.

Hmm, I've never used the no multilib profiles. While there could be some issues because of that, it looked more to me like libav had something to do with it.
By the way, use:
| Code: |
$ equery uses mythtv
|
to describe the USE flags. I do believe mythtv uses both perl and python bindings, and perl support is not being compiled in. If you want DVD playback, you'll need to set the DVD flag, and if you want to use a remote eventually the lirc flag is kind of important. 
What exact profile are you using? i.e. the output of `eselect profile list` ? |
