Hyperion.NG, internal Frame grabber does not work with Kodi

micha53 · Jan 27th 2023

Hello,

I have a setup with Rpi3, with 164 LEDs SK6812RGBW, controlled by controller type ws281x (pwm section).

This works fine, at least with the Web Configuration Remote Access tool and also controlled from Hyperion at my smartphone,

but it does not work with the internal frame buffer.

As I have read, KODI needs the "GL driver (Full KMS) OpenGL desktop driver with full KMS" to work and I verified this, with the legacy driver KODI does not start.

But with the legacy driver I see a red ambilight shimmer behind the 4 raspberry (fruits) at the upper left corner of my screen, so Hyperion.NG seems to work with the legacy driver.

With the "GL driver (Full KMS) OpenGL desktop driver with full KMS" Hyperion.NG does not work with the internal frame buffer, all LEDs remain dark.

btw., a trial with the desktop GUI also did not work, this seems to have an own driver.

The Web Configurations color calibration wizard works with KODI, so there must be a way that both tool work together, how have I to configure my graphics driver, that either Kodi and Hyperion.NG are working?

No reaction...

meanwhile I installed Hyperion at my media center, based on a rpi4. This has had some Issues , but now I can access the web configuration tool also at this system.

But other as at my rpi3 (there it only does not work), if I try to select the internal screen capture and click on the checkbox, immediatly the website makes an update as it should do only, if I click on the save configuration button, and

comes back with the checkbox not activated. If I repeat this, happens the same again. I cannot select the internal frame buffer.

Has anyone an Idea?

ok, I tried to activate the internal buffer while kodi was running. If I close kodi then I can activate the internal frame buffer or dispmanX.

meanwhile I am on the wled track, but I do not get it controlled from the internal screen capture, neither framebuffer nor dispmanX. What is recommended??

Hyperion on a rpi 4 and new OS works only with the legacy driver, if you want doing internal screengrabbing.

micha53 · Feb 1st 2023

can I look somewhere which driver is actually used? raspi-config doesn't say this, only lets set it...

At the moment I have it running with wled control, internal grabbing, dispmanX, with some smaller issues, but don't remember wich driver I selected as last.

.... should it work with buster?

Lord-Grey · Feb 1st 2023

For me raspian OS "bullseye" on an rpi4 works with screen capture

in the /book/config.txt, you need to have the kms driver disabled

# Enable DRM VC4 V3D driver

#dtoverlay=vc4-kms-v3d

micha53 · Feb 2nd 2023

Yes, I have it disabled, so it is logically, now I only wonder that Kodi works with disabled KMS driver...

Do you have Kodi working at the same system?

My kodi actually works with pitures, but playing videos is not ok. At last kodi freezes after video start.

I made some tests:

1st, raspi-config does not offer me the menu point to change the driver, so I enabled it in config.txt,as result the raspi does not start anymore

after these last logs

the screen gets black.

I had to turn this setting back and it works again.

Can this behavior come from hyperion installation?

How can I prevent Hyperion from starting after boot? I'd like to look how kodi and the gl-driver behave when hyperion not is working.

micha53 · Feb 2nd 2023

It is always a better idea to read the actual original Raspi documentation than search the whole internet and find thinks that are outdated....

I've done this and now it is clear that with bullseye at rpi4 some thing are other than at rpi3 with buster or older Op. systems, where I made my 1st steps with kodi, tvheadend and hyperion....

Forget my questions above, in only one thing I am still interested: What is your rpi4 cooling method and do you have temperature problems playing pictures or videos with kodi?

I think this is not the legacy driver, because the kms driver is the default for rpi4. Doc

That is why we cannot activate the kms with config.

micha53 · Feb 12th 2023

Hallo,

today I come back with some new information and a new "feature".

I have Hyperion working now with the screen capture like shown in #7, working in wled mode. (btw. wled really works great.)

Now I have a new feature. If I start kodi, already at the start screen, and furtheron some leds are bright shining white. These are the same 30 leds at the top and 28 at the bottom, leaving 17 leds not affected at the left side and 37 at the right, also overspanning the 2 gap positions at the bottom.

Beneath this, the kodi colors get extended like expected.

I have no idea where this bright overlaying area does come from.

If I leave kodi, the effect vanishes.

Who has an idea where this behavior comes from?

protocol attached.

micha53 · Feb 12th 2023

With pwm mode (ws281x) I have the same behavior.

Reinstalling kodi brings no improvement.

manhmz · Feb 16th 2023

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 {

hook_args [
{
interface PCM
name "IEC958 Playback Default"
lock true
preserve true
value [ $AES0 $AES1 $AES2 $AES3 ]
}
]
}
}

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 {

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.

I made the experience that it works with the kms driver. Or did you see the same feature like me (#11) with the kms driver. Lord Grey (#7) seems to have it working, too.

I know, that with ws281x mode i have to use hyperion as root user and lose the audio facility, but I selected the wled mode and installed wled at a ESP8266...

manhmz · Feb 16th 2023

Remember, RPI3 have three modes: FKMS, KMS and Legacy.

Disabled kms (legacy) driver only work till Kodi 18.9 though, newer Kodi required fkms or kms driver. And DispmanX - Hyperion screen capture is based on fkms, I would suggest follow my tutorial with newer Kodi 19.5 and latest kernel for security fix.

For the audio, fkms is not detecting HDMI Audio driver that's why I included an tutorial to add HDMI audio and it should work normally.

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

manhmz · Mar 7th 2023

Yes you can, but I would recommend switch libreelec to OSMC since they have an package manager

Hellcube · Apr 25th 2023

Dear Manhmz i have tryed your tutorial, and it worked for the hyperion and sound. But i lost my CEC functionality (when i go back to vc4-kms-v3d CEC works again). I'm using OSMC on RPI4. Thay say thay do not support fake MKS on OSM. Is there a way to make CEC working on FKMS? I found some topic thay may be helpfull.

you should check what is switched on first, yor TV or kodi. I made the expierience that CEC does not work when I switch on the TV while kodi is running. Starting kodi while the TV is switched on it works.

edit:

But I am working with raspberry pi OS and have no expierience with OSMC or libreelec.

Hellcube · Apr 25th 2023

CEC powers on my TV without a problem with FKMS and KMS driver. So it's not the case...
