(madtw @ feb. 08 2005,00:29 Wrote:the installation instructions are a little out of date in cvs. here are some quick installation instructions:i hate to sound like a dummy, but when you say the "entire contents" of the xbmcmyth directory, do you mean the language, skin, and test folders as well or do i still drop those contents into the corresponding folders in the xbmc folder on the xbox? i did both and both times, when i tried to run mythtvmain.py, it said it was running and then it does nothing. i replaced version 0.15_fixed with the cvs and now nothing works (which isn't saying much yet as i have still to be able to watch anything, but i was at least able to get into the gui) i also just copied the xbmcmyth folder the the xbmc\scripts folder on the xbox and that didn't work either. i am using a build of xbmc from the 4th of february and the latest cvs of xbmcmyth. my backend is mythtv 0.16. one other question about the settings. what exactly is the prefix path setting? is that the share on the backend where the recordings reside?
1. upload the entire contents of the xbmcmythtv directory to your xbmc/scripts directory on your xbox.
2. run the mythtvmain.py script and go into the settings screen to specify your connection details and paths.
3. on the settings screen, make sure that the connections test successfully then save your settings.
4. you should now be able to use the rest of the buttons on the main menu displayed by mythtvmain.py.
optional installation includes adding a shortcut to the main xbmc menu:
1. add a new button entry into your xboxmediacenter.xml file that executes q:\scripts\xbmcmythtv\mythtvmain.py
2. update the xbmc/skin/project mayhem/pal/home.xml (or equivalent for your skin) to increase numbuttons by 1.
3. reboot xbox to show the skin change.
thanks

ok, i guess i could have been clearer in my instructions. for step 1, i meant upload the xbmcmythtv directory and all sub directories to the xbmc/scripts. so the filesystem should look like:
Quote:xbmc/
scripts/
xbmcmythtv/
language/
skin/
within the scripts directory, you should have a subdirectory called xbmcmythtv and within that you would have the *.py files. under the xbmcmythtv directory, you would have a language directory and a skin directory.
note: you should *never* have to overwrite xbmc files with this installation method. if you find yourself overwriting files that came with xbmc, then you are doing something wrong and you will most likely mess up your xbmc install.
the old way of installing stuff into the xbmc directories made it more difficult to uninstall everything if you don't want to use the scripts.
technically speaking, you do not need to upload the contents of the "test" directory. the files in the directory are only used for emulation testing outside of xbmc. however, it won't hurt if you upload the test directory with everything else.
my current setup that works fine is a feb 3, 2005 build of xbmc, myth tv 0.16, and the latest cvs of xbmcmythtv.
the path prefix should be a string that can be prepended in front of the myth generated recording filenames (e.g. 1014_20040713103000_20040713110000.nuv) to access the files remotely for playback. the live prefix should be the prefix needed to access the dir where myth will generate the ringbuffer files. with my setup, these two directories happen to be the same. if you happen to share the directory using smb, then it should be a smb share path prefix.
if you use the special value '%h' somewhere in the path prefix, then the scripts will replace the '%h' with the hostname stored in the mythdatabase. this is in case you have multiple backends that record shows. this assumes the remote share name is the same on all hosts. if you only have one backend, you don't need to use the '%h' value - you can put in the hostname explicitly. (if your myth database has fully qualified domain names in the recorded.hostname column, then the scripts will strip the domain from the hostname before replacing %h. this was a bug/feature request from someone that had fqdn hostnames in myth but was sharing using netbios/smb and the fqdn was not the same as the netbios hostname.)
i should note that the prefix can begin with "smb://", "xns://", "xbms://" or anything else supported by xbmc. i have only tested with "smb://" but the others should work as well...

nice work madtw and dev crew
im excited to see the guide skinned up so i can test out live tv!
looks like mythtv 0.17 was released today. hopefully there arnt many protocol changes

i put an old version of xbmc on one of my xbox's and the 0.15_fixed xbmcmythtv in all the right locations. it loads up ok, and i go to the recorded shows menu and press the green button to select the show i want to view, i hear some activity on the hard drive and then nothing. i see no activity on the tv. it freezes up on the selection i chose and i have to power off the xbox and then power it back on. here is a snippet of the xbmc log file:

i have lowered the cache size on the xbox as well to 512k so it shouldn't take very long to begin playing video.
thanks for all your help
- madtw - 2005-02-13
i'm guessing it is a date formatting issue or perhaps a protocol issue in that the incorrect number of fields are being returned compared to what the code is expecting. i also had a number of lockups with 0.15_fixed, mythtv 0.16, and older versions of xbmc. i would recommend using the latest cvs... but you can always have a go at fixing the code in the older versions if you prefer to use that.
adjusting the video cache for the recorded shows is not as critical as it is for the live tv. the issue you are having is because of bugs in the code... not with your cache settings.

update to the latest cvs... i made some fixes this weekend (e.g. trailling slash, hostname expansion, etc). i also added in a new setting so that you can specify the mininum ring buffer size before the xbmc video player is launched. that way you can play around with the xbmc cache settings and the ring buffer minimum size until you reach a happy medium with caching of video versus time it takes to start playing live tv.
as for the wrong ring buffer filename problem you mentioned, i haven't had the problem with my setup. the script gets the name of the ringbuffer file from the myth backend so i'm a bit surprised that it gets this wrong. on my setup, the ring buffer filename is ringbuf7.nuv so we haven't hard coded the name of the ring buffer in the scripts. i'm not saying that the logic is correct in the script... but it isn't as simple as fixing a hard coded value. if you launch the mythtvlivetv.py script manually (i.e. not from mythtvmain.py). it will slow it down a lot but the screen will log all the myth protocol stuff to help in debugging.
the .conf stuff is xbmc behavior... i'm guessing you can specify configuration options for each video file if you like. so xbmc checks to see if such a file exists whenever it launches any video file.

error
(10057, socket is not connected)
1. make sure you entered a fully qualified domain name for your backend server or the correct ip address. a name like 'banshee' will not work because the dns lookup on the xbox requires a fqdn to work. instead you will have to specify something like "banshee.house.net" or "10.1.2.3".
2. make sure all the server port numbers are correct.
3. make sure the mythbackend is running and the mysql database is up.
4. this might be obvious but make sure your xbox is connected to the network and is getting an ip address on your lan. (this should be the case since you said your shares were working.)

this clearly rocks and since you all know what you are talking about im gonna ask my question right here, hope thats ok.
i have an 2000 server as fileserver atm and was thinking of making it my new stream-comp/digitalvcr. (was hoping to keep running 2k server if possible)
all i want to know is what analog tv-turnercard you all recommend. ive seen so many different and id like to make the right choice right away so it will save me time later.
ex. a analog tv-turnercard that is compatible with the program needed to control the whole thing from my xboxes.
id appreciate all response to my reply, and o man i cant wait til i get it up and running so i can contribute to this thread for real.
cheers guys and keep up the grand work.
/beef
ps. what's the correct name of the program and the plugin that i need on the serverside?

i had some dropout problems initially. i ended up setting up the minimum ring buffer size to 750000 bytes. also, i went into the xbmc cache settings (under system) and adjusted the following:
video cache - dvd rom 8192kb
- local 1024kb
- internet 1024kb
unknown type cache - internet 1024kb
i didn't try playing around to figure out which one was used for myth... but i'm guessing it is just the local one. (note: i didn't actually change the dvd rom setting - this was the default that came with xbmc.)
if you still get drop outs, try increasing the min ring buffer size past 1024kb (e.g. 2097152). that way the scripts will wait until the ring buffer is 2mb in size before xbmc tries to cache 1mb from the beginning.
