That's the setting. Post a debug enable log when playing a problematic video.

Logical next step is to bump the GPU frequency up a little, however if I even attempt to bump 'gpu_freq' up a mere 50Mhz to 550 then when I try to playback a h265 file, I will immediately lose video output but the OS doesn't crash and the Pi is still reachable via SSH and responds to commands so I can revert and reboot etc..
Disable "adjust refresh rate to match framerate" and I suspect you'll get a picture.
Your overclock is having the same effect as "hdmi_enable_4kp60=1" and something isn't supporting that.
Do you have another hdmi cable or 4k display to test with?

I have tried the additionof video=HDMI-A-1:D to the command line, and it kind of works
That suggests you don't have a working hotplug connection on HDMI. Try with a diffrent HDMI cable.

Thanks for the update. Regarding deinterlacing support on Pi4, do we need to enable it somewhere on the settings or it's already on?
No, it's automatic when playing an interlaced file.

Interesting. Nightly/master has moved to 5.15 kernel (compared to 5.10 kernel for Matrix) which is one possible explanation.
-
Probably a kernel display bug, but I'm currently confused.
I just noticed the file played fine for me initially (where I didn't have hdmi_enable_4kp60=1) then later on a different setup did fail.
Looks like the more common [email protected] video doesn't have this failure, but yours of [email protected] does.
I'm guessing the resolution is having some effect on clocks or timing.

I think this is a display issue rather than a video decode issue.
Azurewrath can you remove hdmi_enable_4kp60=1 from config.txt, reboot and try this file again?
-
Are you saying you get video out of both hdmi ports?
Or are you saying you can get video from one port and audio from the second hdmi port?
The original post read to me like they wanted video from both ports, which I don't believe can be done.
Video from one, and audio from the other can be done.

Never cut down a log. The most useful information in the log is at the start.

Sorry, that's not supported by kodi. You may be able to use a hdmi splitter to get the same result.

Code
config.txt: gpu_mem=384M framebuffer_depth=32 otg_mode=1 hdmi_enable_4kp60 dtoverlay=hifiberry-amp100 MALLOC_ARENA_MAX=2 initramfs edid.cpio
gpu_mem=384M - Remove it. That memory is likely just being wasted.
framebuffer_depth=32 - Remove it - will have no effect when kodi is running
hdmi_enable_4kp60 - you need an =1 on end to do anything
MALLOC_ARENA_MAX=2 - Remove it. This will have no effect in config.txt
-
Have you added hdmi_enable_4kp60=1 to config.txt?
-
"dtparam=audio=on" added to config.txt will enable the headphone socket in audio settings.

Almost certainly the hard drive doesn't get enough power.
Externally powering the drive, or using a powered USB hub may fix this

If you disable cec does the issue stop? (just to confirm it is cec related)
If you want cec enabled then you could try just disabling "switch source to this device on startup",
and make sure "devices to power on during startup" is set to none.

For 4kp50/60 yes, but 4kp30 and below will use 12bit RGB 4:4:4 if supported by the TV.
So lots of 10-bit videos (eg 4kp24 or 1080p) now can have 50% higher clocks than before.
