I know for sure, because I use vysor from time to time via network adb.

So we can say:

Most set top Boxes like Nvidia Shield / Fire TV
Android Phones
Android TVs

all have adb on board, so theres a good chance that minicap also works on them.
That would give us a great way to get the screen from Android based devices and use them on hyperion
Especially for people using 4K Tvs, cause no more expensive grabbers would be needed and no problems with HDR / CEC and so on

Another great thing on minicap is that is can resize the output image to reduce load and bandwith

Hello,
I received my shield today and installed the Hyperion plug-in.

I can not start it and I do not understand where to put the configuration file "hyperion.config.json" on Android device ?!

thank you in advance for your help

For the moment you need an extra device like a raspberry in combination with android
ATM just Nvidia Shield-->Kodi-->Hyperion Plugin and RPI / Linux PC with hyperion and the config in /etc/hyperion

Ahhhhh...OK thanks a lot

How will this work with blackboarder detection? I am running Rasplex on the Pi and for Netflix I use the PS4. If blackboarder detection is an option for this solution, an Android device would be the best overal option.

before we find a solution for bb-detection, we need first a working solution for androids...please be patient

Brindosch · February 8, 2017 at 12:06 PM

The blackbar detection works independent from source
It is unlikely that we get a hyperion running on android for the moment

We don't Need hyperion on android. We Need a "device" in hyperion that can handle the informations send from a android device with this minicap thing.

@jeckyll can you provide More Info on how to get this working (as in your videos) ?

Brindosch · February 8, 2017 at 2:29 PM

I would first have a look if the MediaProjection can handle it or not. If it works, it is dead easy to transmit the content to Hyperion.

I did the videos with that:

https://github.com/openstf/stf

just build in a linux enviroment and you can get the screen

thats what I did and seemed to work so far. (had to manually set the resolution, like you mentioned)
How did you display the video? pipe localhost:1313 to mplayer?

jeckyll · February 8, 2017 at 2:43 PM

For the video i just used the included webpage in stf

Brindosch · February 8, 2017 at 5:43 PM

Could someone test if a screenrecorder app is working with netflix, etc and report the status here?
for example this one: I can't test myself
https://play.google.com/store/apps/det…nrecorder&hl=de

jeckyll · February 8, 2017 at 5:59 PM

Amazon works, YT as well. Netflix blanks the screen only the on screen buttons are visible

Brindosch · February 8, 2017 at 6:02 PM

Cool, would be interesting what happens on Android 4.4, if you are forced for root

BioHaZard1 · February 8, 2017 at 9:48 PM

@Brindosch

MediaProjection will not allow us to capture objects (streams) within a secure surface or layer. This also won't work if the application has the secure flag enabled. I've just built Google's MediaProjection sample from source and on Netflix and Amazon video I just get a black screen.

MiniCap does seem promising though, if I get some free time this weekend I'll look into it.

Brindosch · February 8, 2017 at 11:02 PM

Sounds good!
I wonder how he got a picture on prime with the screenrecorder (non root)
Anyway, i think many people are looking forward to this

Hardwarechaos · February 8, 2017 at 11:12 PM

Minicap works pretty good so far.
But not sure about how to connect it to hyperion. Possibilties I see:
- using the minicap binary format (port1313 in the minicap example), but needed to be translated for hyperion
- using websocket (port1717 in minicap), could be opened in a browser and then grabbed somehow for hyperion.

sadly I am no dev, but maybe someone of you has some (other) ideas...

They gave a great documentation about the binary format, so i think this would be the way to go
