Could you state what codecs your files are?
RPi4 has hardware decoding up to 1080p with h264 codec and up to 2160p with HEVC.

I also get the infamous "drop frames before first appearance of srt subtitles" in a lot of files. This happens every time a new block of subtitles appears after some time without dialog.
Are that known issues?
About that issue, I have good results by disabling the "dirty regions" functionality.
Add a file /storage/.kodi/userdata/advancedsettings.xml
Containing:
<advancedsettings>
<gui>
<algorithmdirtyregions>0</algorithmdirtyregions>
</gui>
</advancedsettings>
Got the idea from this thread:
Kodi's Dirty Regions - ARM GPU Tech - improving Kodi rendering performance

If you remove
dtparam=audio=on
And add
dtoverlay=hifiberry-digi
Is it working better?

Using the same addon/plugin as grael, it is working at 1080p, no overclocking with passive cooling only.
Yes, most of the time, 1080p works without overclocking.
But some heavy scenes may stutter sometimes.
For instance the opening scene of Black Mirror (5x01) Striking vipers.
By the way, I've had an update notification for widevine this morning, but the new version is performing far worse than previous version...
Good one:
LibreELECPi4ssd:~ # md5sum /storage/.kodi/userdata/addon_data/script.module.inputstreamhelper/cdm/libwidevinecdm.so

I have it working fine on my Rpi4.
GitHub - CastagnaIT/plugin.video.netflix: Inputstream based Netflix plugin for Kodi
With proper cooling, power supply and overclocking (2 GHz here) it's even working smooth with 1080p

Not yet. Maybe in a few months (no guarantee)

Make sure to use the hdmi connector 0 (close to usb-c power socket)

You need to read the first page of the "LibreELEC (Leia) 9.2 ALPHA1 with Raspberry Pi 4B Support" thread

Hello,
Crackling sound here too on a raspberry 3B+.
I2s output.
audio_pwm_mode=2 didn't fix.
Reducing audio level in kodi by 2 steps make it disappear but a better fix is welcome
Edit : still slight clipping distorsion with 2 steps reduction. 3 steps is safer with loud tracks
audio clipping distortion on i2s output is fixed with this firmware
Thanks guys!

Sadly, it didn't for me.
(But i'm not on the jack audio ouput so...)

Resample Quality is set to Medium
But there is no resampling as 'Audio output configuration' is set to 'Best match'
I may try a 8.2.3 build with newer firmware but it will take a few time (I need to rebuild from sources to use a custom overlay...)

Cpu clock is dynamic.
It changes depending on cpu activity.
600 MHz is idle speed, not max speed.

For music, I don't use tv screen to browse on my Pi.
I use yatse on an android tablet, much smoother and efficient.

Keep in mind there are other types of users - you are not the center of the universe.
Ok...
So my own personal universe has just been convinced not to answer your questions anymore.

Ahem... This is not a bug, and it's not a Kodi thing...
It "could" be done in libreelec, but really, putting the sd card on your computer to edit config.txt is not that complicated. And there, you can copy/paste the keys, setting them with a tv remote would be painful

Mpeg2 is the standard used in dvd and dvb sd. There is a software codec in libreelec, but the hardware codec is better (and put less strain to the pi2)
VC1 is used in a few percentage of bluray discs. VC1 files are unwatchable on the pi without hardware codec...
