I have a stock install of Knoppmyth R4V5 running. I installed ivtv 2.0rc onto my system after the fresh install.

I was wondering...I keep reading everywhere that ivtv 2.0 drivers were built for the 2.6 kernels; since Knoppmyth is using an older kernel....will it be an issue?

I do notice some video stutter after resuming playback from pause and some sound cutouts too. Sometimes the entire front-end will crash when I fast forward live TV (when the live TV has been paused for some time). Now I know that there are issues with Mythtv .16 that may cause the problems I am experiencing.

This brings me to my next question....I know some people have updated their Knoppmyth installs with Mythtv .16 CVS and have had good results...does anyone have any "tips" in updating my system? Anything I should look out for? Is there anything else that needs to be downloaded or extracted from source before I get the CVS of Mythtv .16 and compile it?

Any info would be appreciated.

Thanks,

Steve

nope works great

its the 5th post down i think.. just obviosly use .2rc instead or whatever they say to use.



Never used .16 for longer then 1day.. <one mans oppinion=> the bugs in it dont make it a worthey release</ one mans oppinion> i just use .16cvs



follow the howto: 4th post down i always use cvs in my production box, and overall have had less problems then on the .16 release.

i love cvs.. because once you have a problem just upgrade to the newest one and most of the time its fixed.

Just curious: do you use XvMC playback?

I went through the CVS compile route and though it yielded some bugfixes it still crashes sometimes after pausing. Fastforwarding and rewinding never failed me (yet?). I'm not sure what's causing it, but I suspect it has something to do with XvMC. My system really needs XvMC so I'll have to stick to it and learn to live with the bug... until it's fixed.

I'm not alone on this one:

So your manual compile may not solve this specific bug yet, for me it was worth going through the CVS compile. I have smooth playback using XvMC, Mythvideo automatically launches the second part of a two part film, I have ALSA support now, I have LCD support now (now my VFD display shows the current show e.g.).

You need a video card w/ drivers that supports XvMC (nvidia). Uncomment XvMC related items in settings.pro and compile...

hmm good point. i have never used xvmc. so i dont have any intellegant comments on that I now wish Xvmc worked(well) with myth.. since my 3000+ is breathing heard just trying to watch HD tv!

Well I haven't had any problems with XvMC on standard def, but It dies hard on High def. Supposedly it's a bit better in CVS, but still not good, so for now I guess I'm just stuck without using it, since I'm not going to go through the hastles of upgrading to CVS for slightly better XvMC.

Ok....I installed MythTV .16CVS according to gr8nash described in a previous post he linked too. I ran into 2 problems after installation:

1. My framebuffer driver (ivtv-fb) would not load up even though I have it specified in my ivtv modules file. I didn’t make any changes to it and it worked prior to removing .16 and installing CVS. My temporary fix for this was to add "modprobe ivtv-fb" to /etc/rc.d/local and have it load up upon booting the system.

2. My mythbackend is not starting after boot up! I'm going to kick myself for this in a bit but I forgot to bring the error that I found in the mythbackend log file (I'll update this post tonight with the error log when I get home). In short it's complaining that it can't write to a file. The weird thing is that if I open up a command line after booting and issue "mythbackend -d" it starts up fine and works. I tried adding this line to the same /etc/rc.d/local file like I did the modprobe ivtv-fb but that didn't work.

At the moment my box is working great ...that is if I don't reboot it. If I do then I have to issue the mythbackend -d command again to start it....not good for the WAF.....

Any info would be much appreciated

sorry no clue on this one.


yeah that would be good.


hmm that is wierd i would have though the newest cvs wouldnt compile on R4v5. The new cvs requires QT 3.2 or greater. I thought R4 uses QT 3.1, but i dont have my R4 box running so i cant double check...

Ok...the error in the mytbackend.log states that it can not write the the mysql.txt file.

gr8nash: Did you update qt on your box?

no i didnt... so i take it you did? i havent seen that error.. Im assuming you know to check and make sure mysql.txt is there and that it has permissions for it?

mysql.txt ix there (I assume it is in ~/.mythtv)

I didn't update QT on my box.

What Version of Knoppmyth are you running? How did you get CVS installed? Weird........i may have to re-install R4V5 and start from scratch again, things are acting wierd on this box.

R5 alpaha



honestly i didnt even try.. at some point i will install r4v5 again and upgrade it.


with knoppmyth that is often easier then figureing out the problem.. when i have played with Fedora i would spend days trying to figure out a problem since a reload is a major undertaking...

One more question:
Do you know if there has to be anything done to the MySQL server (database more so) after updating it to a CVS (or any other version) of Mythtv?

Thanks
