Users / Possible to redirect audio to another MD?
« on: January 08, 2011, 04:55:43 am »
Use case - LMCE users who have 2 or more MDs in the room, but only one has 7.1 surround.  It would be excellent if LMCE could redirect all MD audio from one machine to another to utilize the best sound system in the room.


Installation issues / IBM/Lenovo T60 Trackpad Issue
« on: May 03, 2010, 02:18:36 am »

I'm using an IBM/Lenovo Thinkpad T60, using UI1, as one of my many MDs.  When I try to use the built-in trackpad, the LMCE orbiter registers as though "4" and "1" on the keyboard are pressed in a seemingly random order, and eventually jumps the orbiter to the Phone Book (and enters something like "1441444414444144" as I move the mouse).  In KDE desktop, everything functions correctly.  I've played around with the orbiters "Hard Keys Mapping" setting in the Web UI, without success.  This forces me to use only the keyboard to navigate the UI.

Can anyone give me some direction on how to resolve this problem?  At first I thought maybe Xorg.conf needs modified, but everything works fine in KDE, leading me to believe its an issue with the Orbiter software running on this particular model laptop.

Thanks in advance,

UI2 and eventually 3 should scroll up/down with 1 arrow, flipping pages every 10-15 seconds.

Currently UI2 doesn't scroll repeatedly when 1 arrow up or down is displayed in lists...  In my opinion this is a a major usability improvement -  LinuxMCE users could display enormous lists of media in a slower to render, fully automated yet comprehensible manner.  Right now, its hard to follow everything on-screen with lots of varying media in a 2 arrow flipping mode.

If 1 arrow up/down is not meant to flip by design, then I would suggest 2 arrows should scroll through lists slower by default.


Users / Repeated mounting of internal HDs
« on: April 29, 2010, 03:12:06 am »
Running dmesg on my core shows this countless times:

[108910.682591] kjournald starting.  Commit interval 5 seconds
[108910.683374] EXT3 FS on sdb1, internal journal
[108910.683387] EXT3-fs: mounted filesystem with ordered data mode.
[108948.865457] kjournald starting.  Commit interval 5 seconds
[108948.866206] EXT3 FS on sdb1, internal journal
[108948.866220] EXT3-fs: mounted filesystem with ordered data mode.

Seems the volume is being mounted/unmounted repeatedly.  I followed these instructions here for adding a second internal HD to the core:

I then allowed it to be auto-discovered by LMCE, and used an orbiter to add the drive to the system.  Doesn't it seem this is wear 'n tearing the drive, with constant mounts/remounts?  Ideally I think the drive should spin down and not be accessed until its needed, as its only used for media.  After leaving the system up overnight, dmesg returns only the above log entries again and again.

Best regards,

Feature requests & roadmap / Power consumption selection
« on: April 28, 2010, 09:55:45 am »
I'd like to request a new feature - in the web UI's Basic Info > Installation page, have an option to select the desired power consumption of the entire LinuxMCE system (ie Green/Balanced/Performance).  This option might also be available in the orbiter, or configurable programmatically (dcerouter/C++), or even just based on the current house mode.  If set for Green, LinuxMCE switches all Orbiters to a dark theme, aggressively powers down MDs, blanks screens, dismounts storage, reduces/increases climate temp based on outside temp, turns off A/V gear, etc.  Balanced is the standard setting, but should be tuned beyond the current 8.10b2, which seems to run the flickr screensaver constantly.  Performance would automatically start devices in the areas around your location/level based on your location in the floorplan (ie for large installs), quickly engage perimeter lighting, use all unused displays for the flickr screensaver, etc.

This introduces new useful scenarios in which you want your homes power mode to switch to green when your away for an extended period of time, time of day, etc, or when you want your home in performance mode for party/demonstration situations.  I think this is a very useful and marketable feature that could potentially reduce the carbon footprint of large installs and potentially LinuxMCE users overall, while expanding the already obvious existing cool factor.  More brainstorming is certainly needed...  Chime in if you can ;)

Users / Receive HTTP Notification When IP Camera is Triggered
« on: March 18, 2008, 11:37:11 pm »
I have a Panasonic BL-C131a IP camera, which is now working well with LinuxMCE and the motion wrapper.  This camera, and many others, has a feature to 'Send Notification When Triggered', which can be sent via email or HTTP (some Axis cameras have TCP notifications).  This particular camera has on-board motion and thermal sensing capabilities, and allows you to send different notifications for different 'triggers'.

I am very interested in interfacing this camera with LinuxMCE using HTTP notifications, which would reduce the load and power consumption on the core (not to mention the network!).  Basically the IPCam could hit a particular URL on the core when it detects motion or thermal events, passing the type of event to LMCE in a parameter, which instructs the core to record from the camera for a designated amount of time.  This should also eliminate false positives in the security system when someone is PTZing the camera directly.  It also eliminates the complexities of using the motion wrapper, and could allow lower spec cores to monitor many intelligent IP cameras.

While I am able program, I'm by no means a software engineer :)  As I'm also new to LinuxMCE, naturally I have a few questions before I attempt this feat:

-Are there already facilities in LMCE to receive HTTP notifications, and turn them into MessageSend commands to the DCERouter?
-If not, what is the cleanest way to approach implementing this (without hacking something together)?
-Would anyone else be interested in using this feature?
-Is anyone willing to help out with development?
