internal frame grabber only LibreELEC 9.x

Many thanks….

Is it possible on 9.x to use hyperion ng with internal frame grabber for 4k movies?

Hi people,

I am using still rpi4 with libreelec 10 on it. I installed there hyperion.ng from this link:

It works great with my external frame grabber and hdmi splitter. But now I want to know, if it is at this moment possible to use the internal frame grabber. I want to disconnect the external frame grabber and hdmi splitter and cables.

Many thanks all

In Debian 11 Bullseye & Kodi 19+, you would need to use fkms for Hyperion to capture the screen. However switching to fkms rendered the audio from HDMI undetectable, I would recommend a fresh install of the latest OSMC image.

Here is the way to use Hyperion + Kodi on Bullseye:

Install Hyperion:

sudo apt update && sudo apt install gpg -y

wget -qO- https://apt.hyperion-project.org/hyperion.pub.key | sudo gpg --dearmor -o /usr/share/keyrings/hyperion.pub.gpg

echo "deb [signed-by=/usr/share/keyrings/hyperion.pub.gpg] https://apt.hyperion-project.org/ $(lsb_release -cs) main" | sudo tee /etc/apt/sources.list.d/hyperion.list

sudo apt-get update && sudo apt-get install pulseaudio pavucontrol alsa-utils hyperion -y

If you use WS281x LED you will need root, use this command: sudo updateHyperionUser -u root

Fix FKMS HDMI Audio

1. Add snd-bcm2835.enable_compat_alsa=1 to /boot/cmdline.txt

2. Add to /boot/config-user.txt:

no_hdmi_resample=1

hdmi_stream_channels=1

hdmi_force_edid_audio=1

dtparam=spi=on

dtparam=audio=on

3. In /boot/config.txt change vc4-kms-v3d to vc4-fkms-v3d

4. Add bcm2835_alsa cards.bcm2835 to /usr/share/alsa/cards/aliases.conf

5. Create "$HOME/.asoundrc" with the following content :

Code

pcm.mythtv {
@args [ CARD AES0 AES1 AES2 AES3 ]
@args.CARD {
type string
}
@args.AES0 {
type integer
}
@args.AES1 {
type integer
}
@args.AES2 {
type integer
}
@args.AES3 {
type integer
}
type hooks
slave.pcm {
type hw
card "0"
device 1
}
hooks.0 {
type ctl_elems
hook_args [
{
interface PCM
name "IEC958 Playback Default"
lock true
preserve true
value [ $AES0 $AES1 $AES2 $AES3 ]
}
]
}
}

Display More

6. Create "/usr/share/alsa/cards/bcm2835.conf" with the following content:

Code

#
# Configuration for the bcm2835 soc found on RPi
#


<confdir:pcm/iec958.conf>


bcm2835.pcm.iec958.0 {
@args [ CARD AES0 AES1 AES2 AES3 ]
@args.CARD {
type string
}
@args.AES0 {
type integer
}
@args.AES1 {
type integer
}
@args.AES2 {
type integer
}
@args.AES3 {
type integer
}
type hooks
slave.pcm {
type hw
card $CARD
device 1
}
hooks.0 {
type ctl_elems
hook_args [
{
interface PCM
name "IEC958 Playback Default"
lock true
preserve true
value [ $AES0 $AES1 $AES2 $AES3 ]
}
]
}
}

7. Reboot, DispmanX will now show up in Hyperion and able to capture Kodi screen, Kodi now work with HDMI Audio with the capability to passthrough same as KMS.

Could we also install this in kodi self? I have a rpi4 with libreelec on it and installed there the hyperion.ng

I just want to use the internal fframe grabber for screen caputure

So any one idea how to get hyperion working with the tv apps? Only possible with a camera? Or could we do it with another trick?

Quote from TPmodding

This is a DIY self project, mostly used on a raspberry pi with a media system like kodi or osmc etc...this works very well, if you consider that only 2 devs working on this actually.

but some user misunderstand the whole "hyperion ambilight system" cause they want ALL AND EVERYTHING: hdcp2.2, hdr, hdm2.1,4k60hz, and in best case by only installing a "app" on a tv....without a raspberry pi and support for every common china led strip/bulb etc

our goal was never to implement hyperion for any tv... let me explain your "try finding a solution":

i am from germany so i will only list the common tv brands here:

brand 1 LG:

LG: today mostly used with webOS, webOS came with different versions, so the first thing would be:

try to hack webos

try to find out how to get root

try to find out how to root the system the easy way for everyone

reverse engineer the whole system to get what you want

rewrite/customize hyperion to run on the tv

oh but wait, there are different versions...so each step from here needs to be done for different versions

and if LG sees that there is a exploit to hack/root the tv, they will fix it with the new version and then the whole story from zero

here are some references where you can read about about rooting lg tvs

https://forum.xda-developers.c…tvs.3887904/post-78624894

https://github.com/RootMyTV/RootMyTV.github.io

if you want you can get an LG tv, root it with the links above and install Piccap which can grab the picture from the tv

https://github.com/TBSniller/piccap

or you can use tuxusers ported hyperion version for lg tvs

https://github.com/tuxuser/hyperion.rs

brand 2 samsung:

the whole steps from above are similar with the difference that samsung has different "systems (tizenOS)" on each series...and sometimes 2 different proccesor on a model here are the series:

a

b

c

d

e

f

h

j

k

m/q

n/qn

r/qr

t/qt

a/qa

samsung is a little bit confusing, if you want some more infos:

feel free to research

https://forum.samygo.tv

here is a list for some rootable tvs:

https://forum.samygo.tv/viewtopic.php?f=1&t=8274

there is also hyperion for samsung tvs:

https://forum.samygo.tv/viewtopic.php?f=87&t=12551

then there are some other brands like panasonic and sony etc, but i dont know how there tvs, i am only a fan from webOS from LG and the smarthub from samsung

afaik: for things like hdcp you need a general license and then you have to pay in addition for every device (not sure) but we also do not plan to have a own device....

there are only some "options" which you can use but you said you dont want to use the camera method so the only solution is to buy a philips ambilight which has everything implemented....this was not a "weird" answer, it is only "weird" for you because i didnt provide a good answer/solution for you. That was not meant negatively at all.

Hello all

I am over the moon with my Hyperion ng setup via RPI4 + USB Camera however, I cannot get the black border detection to work at all. I have cycled through all of the modes and set thresholds between 1% and 100% with no success. Could someone please advise?

Thank you in advance!

Which camera you are using?

It sounds like a psu problem. Think you have drop low voltage and that is a problem for the led strip.

Quote from pclin

If you know better then don't ask.

It is not a question of what you prefer but what goes with the colors of the TV.

regards pclin

That is true. Many thanks for your info. I think to make step to go the sk6812 from ws2801.

Quote from Mike72

You should also read the answers when started a thread.

I think it is something which color someone does prefer and love

Quote from pclin

Thanks for your reply. I thougt cool white is more like the white of led for car like 6000K. Thougt that wil be nicer. But you say natur white is the best choice?

Yes!

Yes!

You have the link where you bought yours?

Many thanks

Quote from pclin

ww = Warm White (reddish)

nw = Nature White (neutral - best)

cw = Coolwhite (bluish)

If the distance to the wall is less than 12 cm, otherwise 30 is sufficient.

So you say nw is the best?

If the distance is lessthen 12 cm then 60 leds?

I look an aliexpress and sk6812 you can choose between rgbw, rgbww, rgbnw, rgbcw.

Which one doe we need? And 30 or 60 led pmeter.

Quote from pclin

SK6812 RGBW is better then WS2812b (RGB).

APA102 (RGB) is better then WS2812b (RGB).

HD 107/108 (RGB) is better then APA102 (RGB)

I prefer RGBW stripes for the best colors.

regards pclin

Sk6812 rgbw is also better then apa 102?

At the moment I have ws2801 but I think to switch to another led strip.

Quote from Tomasz

IMHO SK6812NW or WS2812B

What is the difference?

Is the ws2812b better then apa102?

Hi,

Which led strip is the best To buy and connect to the rpi with hyperion hyperbian on it.

There are so many options but which is the best one?

Mine ws2801 is rgb. So it is not for all ws2801
