MythTV 0.19 is out!

jdgill0 · Posted: Mon Feb 13, 2006 9:37 pm Post subject:

I seemed to have gotten past the "mysql/pginfo error" problems. Not sure exactly what I did to fix the problem though. I moved /var/lib/mysql to /var/lib/mysql.bak, re-emerged mysql. Run the appropriate post-install commands specified by the mysql emerge, then ran the mysql command for mythtv. Other than this, the only difference than before was during the "mythtv-setup" in the video source, where you tell the individual tuner cards which source to use (i.e. zap2it), I told it to grab channels from zap2it, then I could select the starting channel. Afterwards the mythfilldatabase ran correctly. The filldatabase was run after I emerged dev-php/php too. I also ran the mysql command for allowing permissions to phpmyadmin. Those are the ONLY differences between now and before.

However, I now have a new problem. The liveTV does try to start, i.e. there is a blank screen for a few seconds like I used to get under 0.18.1. mythfrontend creates "some_file.mpg" in my /mythtv directory where I told mythtv to put the recordings. It complains the some_file.mpg does not exist, even though that file is in fact there. I see this error on the command-line when I exit out of mythfrontend. The file is owned by mythtv:video (user:group). Any suggestions on this problem?

Thanks.

Very strange problem.

/etc/init.d/mythbackend start

That doesn't work. Or, more, it starts, but doesn't connect to mysql.

mythbackend

That works fine, except that I need to start it manually after every boot.

I'm quite confused by that...

Hello everyone, I was having the same problems, here is how I fixed them, YOUR MILAGE MAY VERY!

First off, the permissions changed. So I changed every file myth uses, where the lockfile is written, the buffer, the saved recordings. So go into that dir and do a "chown -R mythtv:users *;chmod -R ug+rw *"

I found this out from the logs, by editing "/etc/conf.d/mythbackend" and setting
MYTH_VERBOSE="all"
then "tail -f /var/log/mythtv/mythbackend.log" to watch your logs fly by and "/etc/init.d/mythbackend start" to start it up.

also for the DB changes, do a "updatedb" and then "locate mysql.txt" and set the user/pass/etc to fit your system. I dunno if the install added mythtv/mythtv to the mysql users for that DB, so I just put in root/[blank] ...

Also on a side note, I have a PVR350 and use the IVTV drivers, so I checked the /dev/v4l/video* and the permissions were "root video". myth was not in the video group so I added it and set everything 660. Dunno if this helped but it didn't hurt.

Hope this helps

Be nice if you guys if some of you guys would drop me a line sometimes about any issues. I don't browse the forums sorry. (with that out of the way)

Any MySQL errors usually result in someone having upgraded MySQL along the way and upgrading MythTV or even just re-compiling MythTV. What you need to do is re-emerge QT, this just because the way MythTV uses QT libraries for abstracting all MySQL calls through QT.

With regard to permission problems, yes, I changed the mythbackend daemon to run as the mythtv user. Expect some more work with that user, with regards to making it easier to have a dedicated MythTV box setup.

Anyway, if there's some features you guys would like to see... shoot me an email cardoe [at] gentoo or just come on Freenode (IRC) and msg me at Cardoe.. I'm in #gentoo-mythtv and #mythtv-users. The 1st one is pretty quiet.

Thanks to the last two posters. I did the "chown -R mythtv:users *;chmod -R ug+rw *" in my video directory, added mythtv to audio and video groups and copied ocer /var/log/mythtv to /etc/mythtv and it now works.
Only problem is that after all that there's nothing decent on TV

I am close, but not quiet there. My mysql problems are fixed. I was actually missing a couple items from the kernel config. As it turns out the 2.6.15 kernel needs you to set a couple extra modules not seen in the previous 2.6.14 version:

<M> Add support for additional audio chipsets
<M> Add support for additional video chipsets

Anyways, LiveTV will not start. Mythfilldatabase has run sucessfully. The error I now get is an "invalid file_blah_blah.mpg". This file exists but has zero size. I have changed permissions on my video directory, copied /var/log/mythtv to /etc/mythtv ... however it doesn't seem to be using this directory. The pvr-150 cards seem to be recognized correctly. LiveTV tries to start, but craps out as I said with an "invalid file" error. Here is a list of modules I have loaded:

Hmmm. After trying mplayer to caputer video, I was led to now believing this is an ivtv/kernel-2.6.15 driver issue, at least from my first attempts at research on the web.

Is anyone using ivtv with gentoo-sources-2.6.15? If so, did you have to do anything special to get it working?

Thanks.

I can also confirm that setting my mythtv recordings directory as mythtv:users makes everything work again. I'm sure this was mentioned in the changelog somewhere...I suppose that's an "our bad" or something like that for being dumb and not reading it ;-)

Yay new and updated MythTV!

Well, I now have mythtv working ....... FINALLY .... and hopefully for good! I thought I might be having hardware problems. I am using the 2.6.15 kernel. My system went offline today while I was at work. I am wondering if shutting down somehow "reset" the tuner cards. Before they would not initialize correctly ... saw lots of warnings from kernel during boot, and the cards were being identified as PVR-250. Now the cards are identified as PVR-150, as they should be.

I had volume problems in the past, where the volume went muted on one of the cards. After shutting down for a few minutes and rebooting the volume was OK afterwards (this was on a different machine). Is it possible the cards can become "confused" when trying to setup/install everything and testing of mythtv?

Hopefully, all is truely OK now

Well, since this seems to be a post crowded of mythtv users I ask here:
I'm using freevo since some months, has nothing bad but seems that's unmantained,
so I'm considering to install mythtv also to be "covered" if freevo will broke after an update.
But there are 2 stopping points:

1) I don't use any web interface, just a standalone system with a remote, can I install mythtv
whitout mysql?(I don't want mysql daemon running, and would like to use just an internal minimalist
db for xmltv grabbings, if present)

2) There are options to customize tv-recording (mencoder) command line? I like to have
lavc mpeg4 vhq + my filters + dx50 fourcc for my standalone player....

I didn't see anything in the changelogs--does myth support MySQL 5.x yet? I recall on 0.18.2 the upgrade to MySQL 5 borked myth pretty badly--some changes had to be made to the code manually before compile in order for it to work. see here.

Maybe this is a non-issue, and I just need to recompile Qt, etc?

Has anyone had any problems with the program guide not being filled? At the moment I don't have my tuner card in but earlier today when I had 0.18.1-r1 that wasn't a problem. My guide was filled and I could browse through it. However after the upgrade to 0.19 the screen comes up but isn't populated. I can press escape and go back, however if I use the arrow keys MythTV crashes. The command line gives me an error saying

I've been doing some searching on the myth tv site to see what file format it support to no avail. I'm planning to put a few old pieces of hardware together to have a media center PC below my TV, but I don't really care about recording TV shows. All I want is to listen to movies (mostly dvd/divx/xvid) and music (mostly cd/mp3/ogg). Is Myth Tv a good choice for that or is it a bit overkill? Will it be able to read most media files à la mplayer?

Thanks.

I've got two problems I havent managed to figure out yet:

1. Can't emerge any mythplugins, this is the first error I get in emerging mythvideo

i have to reccomend against upgrading. 0.18 to 0.19 cuased mythbackend to stop working. I finally get mythbackend to run and it no longer records shows (it thinks it did, but never makes a file).

Anyone else using MythTV on an Epia (SP13000)? I tried upgrading from 0.18.1 to 0.19, but it refused to use the hardware mpeg2 decoder and instead decided to use 98.5% of the cpu. I had to revert back to 0.18.1 to get the cpu usage down to a healthy 6-7%.

Has anyone else seen this problem? It's a shame, because I could really make use of the new features in 0.19.
