Developers / Link Aggregation in LMCE
« on: July 29, 2015, 03:15:27 am »
I would like to open a discussion topic on a feature I am interesting in developing and testing for LMCE.  This project is something I could tinker with and do development work on at a bench while the bulk of my system remains in storage.  Before I dive in however I would like to pose some function questions to those much more experienced than I to feel out what the usefulness of this would be in the LMCE network, ie. are performance improvements expected or is this a neat trial with no true benefit other than saying I did it.

Basic idea:  Provide manual configuration options to get network port aggregation working on the core.  A configuration on the web-admin for after install upgrades with manual port bonding or auto-magic detection scripts for installation that would assign bonds between NICs.

Limited initial support hardware:  dual pci-e NIC, quad pci-e NIC,  possible later add support for multiple single inexpensive PCI NICs

Concept:  In a PXE boot environment with all IO routing to and from the core, a 10/100/1000 is understood to be a minimum requirement.  From my understanding of LAG, the gigabit transmission is then split among all nodes pulling and requesting data at once limiting each connected node to a fraction of the 1000mb/s.  Two MDs would get 500mb/s each, four would get 250mb/s each.. etc.  By adding support for two (or more) gigabit NICs working as a bonded eth1 on our cores, network bottlenecks during peak traffic conditions could get closer to the 1000mb/s data per node after the switch.

Network boost, Minimal expense:  LAG would be beneficial between the core and the switch(s) only in my opinion and would require support for additional hardware on the core + extra ethernet cable to the switch.  Single lines from the switch out to MDs would not be needed or beneficial.

Developer/Network Architect Input:  Above is what works well on paper and depending on which article you read is either the greatest networking throughput gain ever or a lab experiment for a rookie Cisco student with no real benefit.

In our networks:

Are there peak transmission times where all MDs want data and we feel our cores cant provide it fast enough?
      Are MD boots done sequentially or all at once? 
      When streaming media from SAS on the core is IO bottlenecked?
Is LAG believed to be a feature worth testing and developing for LMCE 14.04 and later releases?
*Regarding LAG with switch redundancy:  Although it adds some complexity there is also the multiple bonded NICs going to multiple switches for redundancy in network topography.  I see less usefulness here in our networks but could also experiment with this easy enough.

Users / Re: NAS - FreeNAS, LMCE or something else?

I've ran FreeNas, NAS4free and another called "OpenMediaVault" on a networked RAID machine. 

FreeNAS - compared to NAS4free the system requirements are slightly higher but does offer ZFS and other powerful features.  I ran this off a 4gig thumb drive and didn't have to waste a drive bay on a system hdd.

NAS4free - worked better for me and allowed me to experiment with different formats like JFS for mythtv.  I do not believe this offered ZFS but I could be wrong.  I used a hardware managed RAID 5 array via IDE PCIX card and a software controlled RAID 5 via SATA PCIX card.  -- hardware controller limited array size, software controller got around that.

OpenMediaVault - IMO the best user interface.  I was also able to have the NAS watching my UPS via RS232 and other standard features like transmission.

Haven't dropped this project yet.  I haven't had much time to do anything LMCE related lately.

I have spent some time off and on reading up on this, attempting various replacement config files and am now learning what these various settings better to write one that works for LMCE and its media players and capabilities.  For anyone else poking around with this here is the basics.

Enable transcoding = no by default
- change to yes

File extension open-with instructions = matroska is not included by default
- matroska open with _____ ( i would assume xine but I will try others if needed)

MIME type (?) = .mkv is not understood as matroska for instructions further down the config file

* Where I currently am *
- .mkv does not exist in the MIMI type section where the other file formats are present
- early on in the config file there are MIME type rules for things such as .avi = (name) .mp4 = (name)
- later in the transcoding section, (name) is assigned to a transcoding software instead of file type.  Perhaps these MIMEs were grouped early on to save repetition later on? 

Users / Media attributes display priority
« on: March 23, 2014, 07:29:44 pm »
Looking for possible solutions for a simple issue.  Technically a feature request as I imagine it may take some work, but wanted to check here in users section to see if there is already a method.

When adding media attributes to video files I use TMDB, a great add to the web-admin and a welcome change to the Amazon attribute finder.

So many attributes are added however that the synopsis of the movie does not display when a video thumbnail is pulled up.  Movies manually tagged or tagged using Amazon with fewer attributes (director & 2-3 performers) will display the synopsis.

- Is there a method of displaying all attributes without starting the video and then navigating to attributes>more in UI2?
- Could attributes be prioritized to display before others?

Slowly poking away at changes to the config.xml, changing as few lines as possible in hopes of adding .mkv and not breaking anything else.

Because this config file is generated by mediatomb, what is the best way for me to share a patch?  My thought currently is a executable script that runs (and restarts mediatomb) after it's installation.  Could someone help me with permissions on that and upload/submit procedures when complete?

Thanks for the input.  I guess it's time to reassemble the NAS. 

Question on .mkv and PS3 playback.  I have setup PSMS on windows machines and been able to playback .mkv files.  To access my LMCE media through my PS3 I am using LinuxMCE via MediaTomb which does not show .mkv titles.  Is there another method or is that something that needs to be implemented?   

Users / Video File Format
« on: March 06, 2014, 09:02:23 pm »
Wondering what other users have found to be a good video file format in regards to quality vs. disk size. 

When I only had 100 or so movies, most of my collection was ripped DVDs in .dvd format which based on their size (4.7gb +) were pretty accurate copies of the original disk.  Quality was great imo and the special features included on disk were nice to have.

Now that my collection is near 1,000 movies I have noticed a large difference in quality using .mp4 and .mkv files which average 700mb - 1.5gb.  I have animated movies for the kids compressed down to 250mb in .mkv where quality is not critical but for other videos where I intent to watch with HD surround audio and want better picture I am looking for recommendations. 

Users / Haven't posted a thank you in a while

The title should be pretty straightforward.

It's been quite a few (five?) years since I started using LMCE in one form or another.  Even with frustrations I've experienced at times I really appreciate all the work that has and still goes into making this so enjoyable for users like me.  Next weekend I will be setting up a Hybrid for my parents who have until now enjoyed accessing my media through a PS3 and will really benefit from at minimum the ease of access UI2 offers.  Perhaps in time they will also enjoy the additional features that makes LMCE a total home solution and not just a media player.

Thank you to the developers, donators, testers and users who have posted feedback.

Is this request still open Posde?  I moved away from Syracuse years ago but still have a few friends there I could ask to check out a few on a weekend, sending you back select photographs etc.

Users / Re: Is anyone using the Game Player?
« on: February 24, 2014, 09:59:43 pm »
Still using the game player daily.  Mostly SMS titles but guests use all the various systems from time to time.  Cover art works fine.  I've added art to the systems themselves which gives a really cool look when GAMES is first selected.  It reminds me of my old game hardware collection.

I never did figure out the issue I had with my various gamepads and had to bandaid the problem by removing orbiter control. 

Gamepad functions and navigates the onscreen orbiter
Game is selected.
Gamepad functions as a game controller but does not cease navigating the onscreen orbiter
button __  makes onscreen character jump, but also brings up the onscreen orbiter overlay.  possibly closing the game out or opening submenus during gameplay.

Bandaid was removing the mapped orbiter control buttons in web-admin.  I then use the game system options menu to map system control only.

Very specific reply thank you.  I was reading about the UPDATE command but hadn't caught the second SELECT * FROM StyleVariation and had no idea before now PK and FK was primary and foreign key. 

600 was a guess, after UPDATE SET I will regen and try a few different values.  Once I have a clean look I will update my first post in this thread for other users who want the clock in 800 X 600.

I hope it doesn't come out sarcastic, you always manage to give an answer that still requires that I get lost and have to look things up to make sense of your instructions.  I knew what a mouse was when I first come across LMCE.  I am now asking questions about command line editing of mysql.

I have made it as far as figuring out how to look up the PK_Style using the SELECT * FROM Style;

So I have determined that the PK_Style ID # I am looking for is 27.  Somehow I need to now select 27 to view the StyleVariation, then I need to learn to edit a Cell.

db = pluto_main
table = Style
row = 27
column = StyleVariation?
cell = 840?   

I need to edit 840 to a smaller number, like 600.  Sound like I am on the right path?

After reading some articles on fc-cache, I found a listing of various options.

fc-cache -fv

-f: force overwriting of font config files
-v: verbose to show me added fonts?

My network time is limited so prior to forcing a command that could system break what I have and put me back quite a while fixing/reinstalling, I am asking if trying this could possibly cause conflicts elsewhere?

A few photos I have taken over the years with LMCE.  Some are pretty and clean as I like them now, others like my wall are... hopefully identifiable to others who ever struggled to grasp LMCE.

Aquarium for my axolotls (shown as Axolotls, a room, on orbiters) z-wave lighting for dawn/dust and midday light changes.  Z-wave on/off device runs the rain-head pump as a scene button under climate called "Rain"

One of the custom orbiter skins I made.  No true designer work but learned how to replace 260X260 icon graphics.

This was taken when I lived with another LMCE bachelor.  Chalkboard wall!!!

Users / [SOLVED] Orbiter Clock for 800x600
« on: February 03, 2014, 04:47:50 pm »

In order to make the clock render correctly, you may depending on your orbiter resolution need to alter the clock font size.  I have found that a very nice size for 800x600 is a PixelHeight of 600.  Read on below if you would like to know how to change this value for other sized orbiter resolutions.


My thanks to tschak for the clock addition.  I have it although rendered incorrectly and appreciate it already.  Starting a topic to ask for some assistance in making it render as intended.  What is happening now is when doing 4 digit time (anything after 9:59) it places the minute number off the far right side of the screen. 

I followed the steps outlined in the LinuxMCE at Home thread and will go over those now incase I missed or misread something.

1. Downloaded the HelveticaNeue-UltraLight.tff
2. web admin>SqlCVS>update>all - waited for "successfull" in the popped up window
3. Used a konqueror browser and used "fish://" to graphically copy that .tff to my webDT. 
4.  ran the following from my core:
Code: [Select]
sudo -i
cd /usr/share/fonts/truetype/
*dir returned a couple subfolders and HelveticaNeue-UltraLight.tff file

5. Via web admin I selected the webdt under orbiters and selected Full Regen
6. waited for status bars 1 & 2 and the words "orbiter regeneration complete"
7.  Quick reload router

** WebDT is using BlueCrystal skin, 800X600 UI1, everything else works smoothly and fits the skin
