New MythTV add-on using libcmyth

I renumbered my channels (as previously suggested, and now Live TV works just fine, and the EPG data seems correct (when I can get it to load). Great! (Although it would be good in the long run if it could handle the subchannels like 2.1 or 2_1).

Getting the EPG data, and having it stay there, seems to be the most unstable of the features. In the cases where I have managed to get the data to completely load (and have set the "save EPG database" to on). If I shutdown and restart xbmc, the data is gone and I have to re-scan (however this will often crash, see above).

Also even with the settings to update EPG every 15 mins (the minimum), I haven't ever seen the add-on attempt to reload the data in the log. When I visit the "EPG" option in the sidebar, I've noticed in the that for some reason the end date is incorrect:

I too am getting the occasional crash while loading the channels & EPG data.

Have switched my main HTPC to this branch now though.

(but still using the myth:// source to watch recordings as they are grouped by Programme)

Thanks!

Install XBMC PVR with cmyth Addon for Ubuntu 10.10 (Maveric):

Rough Guide To Installing Mythtv:

Mythbuntu: Add to Existing Ubuntu Install:

Go to: http://www.mythbuntu.org/download-type

Select 'Add to Existing Ubuntu Install'

Once the install has finished:


choose:

primary backend

desktop frontend

click apply

You will be asked a number of questions when installing mythbackend:

Root Password-> leave it blank

Other Computers-> yes

Exclusively for mythweb -> no

Once Installation is complete start mythtv:


warning box: must be a member of "mythtv" -> click yes, log out

When Logged back in you can go to:


Configure your system.

Optional: Auto-mounting Media Partitions:

Find Drive Number / Name:


Terminal Output:
Device Boot Start End Blocks Id System
/dev/sda1 * 1 5860 47067136 83 Linux
/dev/sda2 5860 91201 685502849+ 5 Extended
/dev/sda5 6104 91201 683549653+ 83 Linux
/dev/sda6 5860 6103 1952768 82 Linux swap / Solaris

In this case the media drive is sda5.

Open the fstab file to add the drive to 'auto mount':


Add something like:

# <file system> <mount point> <type> <options> <dump> <pass>

/dev/sda5 /media/media xfs defaults 0 1

'Drive Name' 'Mount Location' 'Partition format' 'Other stuff....'

Mount the partitions to test:

I have started using this add-on instead of mythfrontend. I intend that it will gradually replace mythfrontend all together.

I keep noticing little bugs, i just need to remember to report them.

One issue is that the recordings aren't updated. The timers update instantly but if a recording starts i have to restart xbmc before it appears in the list.

A more general enquiry, what needs to be done to get time shifting implemented? i do miss not having it

Thanks,

thank you very much for this addon and the guide.
I have one question though:
I see that through the menu bar I can pause the watching during liveTv but if I press the pause button of my remote it doesn't work.

I'm trying to reproduce the EPG/Channel crash but not luck so fare. But I did uncover a deadlock in the PVR code.

Dubstar_04: Thanks for the tutorial. I will add it to the first post.
I suspect that the only thing missing for a working time shift(including the pause button) is skin support. Try searching for previous attempt to add time shifting to the confluence skin.

Spoke too soon about recordings showing up: sometimes they do (and quite soon afterwards) and sometimes they still haven't shown up 8 hours after they have finished recording.

I think I might have only started getting the crashes when I started increasing the number of days in of EPG data to save to 10 or 14 days. (i.e. with the default of 2 days, I didn't see them, at least not as much). I did notice my CPU usage went up considerably while doing the reset EPG and the "save to db" option enabled when I had a larger number of days. Perhaps the problem is at the sqlite level?

Ideally I'd want all 14 days because SchedulesDirect provides the Mythbackend up to 14 days in advance, so I'd want that exposed to the PVR

Just a question, but what is the point to having all 14 days just because the backend has it? Are you really looking that far ahead in your EPG data? The backend will still calculate all the upcoming recordings and such without XBMC having the guide data.

Just wondering.
