Autoresolution

[Rob van der Does]

I was wondering the same thing. Trying to make a setting to get those services to output the same resolution as the source failed here.

The Autoresolution plugin in the VTi image is the best I've tried so far ... it has UHD modes added for Interlace and Progessive scanning too ... but like the Vix/OBH images no modes for 1280*720 ...

I'm sure Autoresolution could be adapted to add the modes required???

Hmmm...I look at a file once, for a coding issue, and become The Expert!!

But let's see....

 

[birdman]

Is it possible to add a mode for 1280*720 broadcasts to the plugin? (i.e. for German ARD channels etc.)

That looks like 720p to me. But there is 720p24 and 720p25.

Could you switch to one of these channels and you'll see entries in the debug log from these statements:

                                print "[AutoRes] new content is %sx%s%s%s" %(width, height, prog, frate)
...
                                        print '[AutoRes] determined videomode', new_mode

What do they report? Indeed, any [AutoRes] lines would be of interest.

They broadcast in this standard and with there being no mode available to set as 1080P in the plugin my TV defaults to the 2160P default in the AV settings menu.

Not sure what you mean by "there being no mode available to set as 1080P in the plugin".

It sounds as though what is actually needed here is a maximum resolution to set (i.e. the user should be able to remove things from modes_available on the box if they aren't available on the TV that will be displaying them).

It might help if you could record a few minutes of this and post the file somewhere for me to pick up?

Hi Birdman,
Glad someone with "brains" on the case!! lol

OK ... here's a resume of my set-up (which I'm sure many others have now too at home)

TV1 - Panasonic 4K 2016 model
TV2 & 3 - Panasonic HD 2014 & 2015 models

(all TV's set to Auto Change according to resolution received, i.e. auto switch from 2160-1080-720-576 dependent on signal)

Sat Box - VU+ Ultimo 4K

Images (on Multiboot) Vix 4.2.027/OBH 0.6.027/VTi 11.0.1

AV Settings (VU+ Ultimo 4K) - Set to: Mode=2160p Refresh Rate=Multi

AutoResolution Plugin - Enabled (and each mode configured as follows)
ALL Modes set to 1080p50 EXCEPT ... HD Progressive which is set to DEFAULT (i.e.2160p as per AV settings see above)

This results in my 4K TV auto switching to 2160p for 4K received signals (e.g Astra UHD Demo10994H 22000 5/6 on Astra 1 @ 19.2°) and then back to 1080p50 for all other non UHD channels ... brilliant!
However, on my Standard HD TV's they obviously don't have 2160 resolution capability so if i tune to a 4K channel on VU+ box it shows black screen ... (that's OK as at mo not a lot of 4K programming and its just means an expense to get another 4K capable TV lol ...)

All was fine until tuned to the FTA HD German channels on Astra 1 ... (e.g. 3 Sat 11347 V 22000 2/3) ... my 4K TV switched to the DEFAULT AV Setting of 2160p for these channels even though they show a Broadcast resolution of 1280*720p50 ... and so on my NON 4K TV's the screen is now black as the VU+ Box thinks its a 4K signal being received!!

The ONLY thing I put this down to is that the AUTORESOLUTION plugin needs an extra "Mode" added to deal with this resolution ...

When using the VTi Image the problem DOESN'T occur ... the German channels show as expected in 1080p resolution ... and I BELIEVE because their AUTORESOLUTION plugin has two EXTRA modes ...

UHD Progressive and UHD Interlace modes ... so this means that HD Progressive can be set to 1080p and not 2160p as it is in VIX/OBH images (IS THIS THE ISSUE???)

My settings are as per VIX/OBH - 1080p for all modes EXCEPT for the UHD modes which are set to DEFAULT (i.e. 2160 in AV Settings Menu)

This is probably as clear as MUD but please say if you need more??

I added pics for AR plugin from VIX and VTI image and you can see UHD modes added.

Cheers,
Nitemare.

Have you considered not using AutoResolution at all, fixing the output of your box to match the resolution of TV set to which it is connected and letting the box scale to that resolution?

The box can only output resolution that are available to it. Does it actually have a 720p50 capability? (I suspect it does, but worth checking).

So login to the box, run cat /proc/stb/video/videomode_choices and post the result.

LOL.... That's the Ostrich policy
Of course that's an option, but the idea of the AR-plugin is to let the box's output resolution to match the resolution of the source. Or in other words: to make the TV do all the scaling or the STB.
We do have a mini version of AR built in ViX, but the AR-plugin is meant for people who want to have all possible options.
I'll upload a short recording from a German 720p service to our FTP-server.

 

[DaMacFunkin]

So what happens when you change the 720p refresh rate from multi to 50hz?

EXACTLY ... AR is meant to give you more choices!!!

Like i said the VTi version of their AR works perfectly?? I'm putting it down to the UHD Modes theirs has and AR VIX/OBH doesn't??

 

[birdman]

EXACTLY ... AR is meant to give you more choices!!!

But it also means that you arrive at the situation where the box is scaling to one resolution, then your TV is scaling from that to its native resolution (which it will always have to do unless you send it a signal that is its native resolution - it only has one screen geometry).

I agree, scaling twice is really defeating the object and should be avoided.
The scaling in the Ultimo4K is pretty good i think.

 

[birdman]

LOL.... That's the Ostrich policy

I was just promoting what I do. I let the box do all of the scaling, and it always outputs 1080p (or 1080i) to my TV. A setup that is simple and works.

but the AR-plugin is meant for people who want to have all possible options.

Both possible options! Either the TV or the box does the scaling. Although I have a suspicion (from reading the code) that using the AR plugin means that there will be situations where both the TV and the box will be doing something, which isn't ideal.

I'll upload a short recording from a German 720p service to our FTP-server.

Thanks.

This can all be fixed to work by adding UHD (2160p) Interlace & Progressive to available Modes in AR ...

The problem at moment is that VIX/OBH only has an HD Progessive Mode ... so any HD mode not covered by HD Interlace will default to the 2160p I have in the AV Settings Menu ...

Yes ... I could have set my AV Settings to 1080p but then whats the point in me changing to the 4K VU+ box then or having a 4K TV??

So What if it involves scaling twice if in the end I get the picture to show on my TV with correct resolution?

I'm not as talented as others on here, (coding wise), but would it be possible to look at the VTi version and see if the VIX/OBH AR could be adapted to be similar to it as it works perfectly?? Obviously it would involve contacting the author of VTi version to avoid any plagiarism issues??

I actually meant that you set the output of your box to the highest shared resolution of the box + TV. You'll notice I mentioned 1080i and 1080p - that's because whereas my TV can handle both, one of my boxes can only do 1080i, not 1080p. So on that box I set it to that, while on the other I set it to 1080p.

So with a 4k box and 4k TV I'd set the output to 4k.

Out of curiosity Is the PLi AR a plugin or built in feature?

Possibly true. But "available_modes" is actually something it reads from the box itself, so I need to look through the code to see why such an option needs to be added, rather than just appearing.
