Users / Re: Why Do Media Directors Exist?
« on: August 22, 2014, 12:17:46 pm »
How do you deal with watching liveTV using a media player? Does the TV signal, whether it's satellite, freeview, cable, whatever, still go to the core?

Also do you lose the onscreen orbiter? If yes, while not a showstopper, I would say it's a disadvantage, it's great being able to do anything from anywhere.

Cheers,
Matt.

Matt - see my earlier post in this thread re LiveTV etc. But the short answer is you can watch live TV via you actual TV - we provide control of the TV for this purpose and you can also watch live TV via any STB's you have controlled by your system too (either locally in the room or sometimes via a video matrix for a larher install where you have centralised STB's distributed through an HDMI Matrix).

Yes you do loose the Orbiter UI on the TV... but you have it instead on your tablet or smartphone instead. The UI then is right in your hand... and you can switch to any room/device and control it without having any TV's on at all...or turn a TV on from tablet/smartphone if you want to etc etc.

All the best

With regards to power usage, I have high hopes that rPi (or similar) based MD solutions will provide the best of both worlds:

1) standardized hardware
2) full MD

phenigma has been very busy with it, and I applaud his efforts.

Well hardware like Rpi would definitely deliver on the power usage front of course - the hardware in a Rpi is broadly similar to small media players. And I also applaud anyone, including phenigma, who actually does some real development and pushes the envelope in any direction. So I'm not knocking that effort or saying its in any way worthless at all.

But at the end of the day whatever hardware an MD runs on you still have additional complexity that I think for a very large number of people/installations is not an advantage. Yes if you want the VDR/Myth TV UI integrated then its probably the best route...but adding those to an MD (especially Myth) always causes some problems in my experience. And of course for Myth, and i expect this might be true too of VDR but I'm not sure, you can access recorded content via a media player or SmartTV - we still have installations where the MythTV backend is running on the Core and all the recorded shows are access via upnp on media players. As long as you aren't worried about live TV then that works well.

All the best

For me, the MD has the advantage that I am in charge of it. And *I* have the means to modify it in any way I like it.

Another major point for me is VDR TV consumption. I have yet to find another networkable TV solution that allows recorded and live TV as good as VDR. That's why I stick with MDs.

If I were to watch streaming content, downloaded content or removable disk based content only, I might change my view. But for now, I love the TV functionality my VDR inside of LinuxMCE gives me.

Both very valid and good points. Being in charge of, and being able to modify, your MD is essentially what i was referring to in my last paragraph. And if you are a VDR user then I can see why loosing that would be a big hit.

First off I know this post will be contentious for many of you...but read on and then respond;

Back in the day when Pluto Inc were first developing Pluto (of which LinuxMCE & Dianemo are direct descendants) the Tech world was very different;

- Crestron were the Elephant in the room (still are?)
- Everything was expensive (I mean everything)
- There were no inexpensive Media Players or SmartTV's
- No inexpensive Tablets and SmartPhones hadn't been invented
- Building custom hardware was difficult & expensive

Its in this context that PXE booted Media Directors were born. They solved several problems in one hit; They enabled a '10 foot' TV based custom UI, they played local CD/DVD discs and could stream video from the Core, they provided local in-room control I/O at essentially zero marginal cost. At the time all these capabilities made incredible sense even though they added complexity. But today they largely don't.

Today the UI has migrated to your tablet or smartphone and is touch driven, we have low cost IP controllable media players and Blueray/DVD players that can play disc media and/or stream video content from anywhere, independent small IP controlled I/O is cheap and easy to install where ever you need it. The Media Director is a hangover from a previous age. It adds cost, complexity and adds considerably to the amount of energy a system consumes. Its another point of failure and a source of many problems both for those building and installing their own systems and for those using systems too.

How many threads here in the forum relate to problems with MD's? I don't know the number but its a big one. And they continue to cause reliability problems in use too. Yes some installations have MD's that don't cause any problems - but most do experience problems at some point. Of course upgrading from one OS release to another is also problematic too in terms getting displays configured and working properly again.

Removing MD's, using Orbiters on tablets or Smartphones and using IP controlled media players/SmartTV's seems to me to be a much better approach overall and its the one we've taken with Dianemo. It improves overall reliability, lowers energy usage, reduces the physical size of your system while improving video playback quality & performance.

For some of us its the challenge of getting our systems working that is the payback and in that sense MD's improve  systems! But I think for most of us we'd like fewer challenges and more smooth and rewarding usage of our systems. After all there are an infinite number of other pieces of hardware you can get a challenge from when integrating that won't stop your family from watching Game of Thrones ;-)

Comments?

Did you get a chance to do any testing Andrew - looking for an Android solution for Dianemo, and see the same issue as reported in this thread with Dianemo and the touch orbiter.

Yes I did. But I obviously then forgot to post an update here. Sorry!

There are some basic issues with this version of the Android Touch Orbiter that are not now compatible with Dianemo and would require a reasonable amount of effort to fix.

However we are developing a new Orbiter that is built in HTML5 and renders its in-screen UI in HTML5 too. See this thread for some screen captures and some details; http://forum.linuxmce.org/index.php?topic=8880.msg99799#msg99799

There are several major advantages to our new HTML5 Orbiter;
  • It can be rendered by any modern web browser or by an embedded HTML5 view in a wrapper App on any device and any OS.
  • It renders to a live HTML5 canvas and therefore the pre-rendered screen bitmaps are not required.
  • No Orbiter regens are required - ever. As we are not pre rendering screens as all Orbiters have required us to do previously
  • It can render dynamic UI elements like sliders or any other control you can imagine that can be coded in HTML5
  • Orbiter screens/UI's can be designed & layed out by anyone with ordinary HTML5 design skills - No HADesigner required!
  • New Skins can be designed without any programming or low level skills - just HTML5
We hope to ship the new HTML5 Orbiter as a Dianemo update in mid Q4 2014.

The whisperer device is in svn but is not being build. I am not aware of any corresponding UPnP code in our svn. Could you (or Radu) point me to the appropriate place, so I can incorporate it into the build?

Thanks.

Radu the best person to do that. One of the problems that may have caused this (based on a vague recollection of a discussion) is that our whisperer based device templates have a bunch of dependencies in terms of screens and our different pipes system etc. All of which would need to be resolved to some extent to get our devices environment working acceptably outside Dianemo.

Users / Re: Can I control a DLNA device (SONY TV) from Linuxmce?
« on: August 19, 2014, 11:49:38 am »
Just a quick update on this topic;

We use a combination of device templates to control SmartTV's. See our Wiki page section for specifics; http://wiki.linuxmce.org/index.php/Dianemo_S#TV_Control_In_Summary. I think this section needs some updates for other brands of TV's - which I will follow up on asap. Most modern SmartTV's are controllable to some extent by using our Universal UPnP template alone but every make/model varies a lot in this respect. One universal limitation is that if you force  SmartTV's into stand-by mode with an 'Off' command they will not respond to an 'On' command to wake them up again (because the network port is powered down in stand-by mode!). So we always use our CEC HDMI over IP device to power up TV's from stand-by.

So depending on the brand of TV we use one or all of the device templates mentioned to deliver control of the TV. Its a little bit messy but until TV manufacturers standardise how they implement this this is not going to change - don't hold your breath for that!

All the best

Andy

@Andy: do you have a definitive answer? ;-)

As far as I know the various UPnP devices have been committed but they may not have been integrated as all our devices are built on our bash based DCEwhisperer framework (which was also committed but not integrated as far as I know either)

Isn't it possible to link the software volume control to the hardware volume control in a sense that when one of the software volume levels is at max level it will increase the hardware volume and decrease the software volume of the other (not being increase) channels so they stay at the same actual audible audio level?

I can't see that working to be honest. But even if it could be made to work the only advantage I can see is that all the signals are transmitted down a single cable. It seems a lot of complexity for no real gain.

I am using pulseaudio. there you can make a virtual device for each channel and then control the volume of that channel. Off course then you not using the volume of the receiver (maybe with some smart calculation that can be linked together).

...thats the point you can't control the Amp gain levels for discrete channels or pairs of channels especially as the Amp is receiving a 5.1/7.1 signal down the HDMI (I assume?)

Developers / Re: squeezelite as an alternative to squeezeslave
« on: August 13, 2014, 06:27:46 pm »
I would use the existing DT otherwise you will have to change code since lmce needs to know that it is usable for playing audio. Thom pointed me to it and I made the changes but probably did something wrong cause it did not work and I ended up using the existing DT. Since phenigma wants to replace squeezeslave I see even less need to use another DT since otherwise you end up removing the same code afterwards ;-).

If possible please add a optional configuration to be able to specify pulseaudio sinks. Has no influence on the way it works for normal usage and might be useful later on (I use it myself since I run on pulseaudio).

We use a separate DT in Dianemo for SqueezeLite as we need to keep existing installations working with Squeezslaves.

cause I don't have a receiver with ethernet yet (mine are still from the RS-232 age). However on my desktop I use a hdmi cable to my amp which has 7.1 and by selecting a virtual output on my desktop I can select which channel of the 7.1 is playing sound. So if an amp can stream 7.1 / 9.2 then the only question is what is the best way to stream that to the amp and to control and automate that. Starts to sound like a nice feature ;-).

The problem is that if you inject a 5.1 or 7.1 signal into your Amp over HDMI (or optical, Coax) you have no volume control over the individual channels that make up that signal.

Me neither. I guess one could get the mux part working, however, all receivers that I know, do not have the ability to define multiple zones from a single digital stream. You might be able to output sound to each of the speakers, but wont be able to change the volume using zone volume commands.

I've never seen a receiver that can define a multiple zones from a single stream either and yes volume control would be a problem too.

Re Motion: http://wiki.linuxmce.org/index.php/Advanced_IP_Camera allows this on LinuxMCE atm.

Re UPnP Controller @LinuxMCE: As far as I know, the code has not been committed into LinuxMCE atm. I might have missed it, but I do not think so. totallymaxed probably has the definitive answer.

Thats a different approach, but an interesting one. In this approach each 'Advanced IP Camera' manages its own events and services and motion is not running centrally at all. Some dedicated IP Camera PVR's (eg Camera Servers) also manage their IP based cameras this way too with the PVR simply getting events from each Camera when something happens local to the camera.

In the future Dianemo we will have a 'External Camera Server' device that will get events from the Camera Server when a motion event is triggered by a Camera. How the camera server manages its cameras is abstracted in our case. The objective is to lessen the load on the Core and therefore allow us to shrink the hardware required at the Core, and lower energy usage. At the same time this improves reliability and is more fault tolerant too.

All the best

I assume, espergu wants to mux the output of multiple squeezeslaves on the core into a single digital stream that gets send out to the AV receiver over HDMI or TOSLINK, and wants the receiver to output the received data into the various output zones.

Yep...I got that. But I'm not aware of anyone successfully implementing that...unless espergu plans to give it a try?
