This is the same file I sent. 
I quickly downloaded the other two files you opened according to the log. With my M8S, I got these results over Ethernet (via Samba):
- Elecard_about_Tomsk_part3_HEVC_UHD.mp4 -> It works over Ethernet, no buffering issue.
- TCL Supercars 4K Demo.mp4 -> 100 Mbps Ethernet is not enough for this bitrate, always buffering.
Then I don’t know what was that you tried to play, but it didn’t like it...

Try this 2160p 8-bit H265 demo video: LG: View The Feeling UHD 4K Demo | 4K Media
If that doesn't work either, you have a clone box with only S802 SoC.
The S812 SoC doesn't support 10-bit (HDR) from H265, only just 8-bit supported.
Can I get a dmesg log?
Hi MakaaiD,
Basically, the problem with the M8S is that it has been made by a lot of Chinese manufacturers and there are at least 20 variants or more of it.
They are basically the same but come with a different WiFi chip, a differently written bootloader, and multiple remote controls.
My M8S (in which I just replaced a 5V1 zener diode because I smoked up it with a 12V power supply) is an n200C version.
The copy made by Eny is a stock n200 and I would need that now. Somehow we should find out what yours is like.
You should try my M8S+ version on an SD card. If it works without error (except for the remote control), it will not be of an Eny type.
If anyone has an M8S box made by Eny, please contact me. (Possible PCB IDs: M9_V0.92 or M9&M8_V1.0)
I have been trying to find one for a long time because several people have already approached me with it, but I just can’t find it anywhere.
You are welcome and thank you for your feedback. 
Hi Samui,
I'll check it out, but I'm currently suffering with the avl6862 driver, under aarch64 it doesn't want the truth.
Hi dtech,
your image is working great on my Mecool KII Pro - thank you very much for your work!
Would it be possible for you to compile the makemkv addon to this release.
I connected my external BDROM to the box for use it as BD Player also, but many of my original BDs
are protected.
Thank you for the feedback. I'm glad it works under KII Pro as well.
I tried to find something meaningful for makemkv, but what I found so far only included PKG_ARCH="x86_64".
Does it work on Amlogic device at all? If you had such an earlier version, I would like a link.
You can try my KI Pro image, but you need to replace the dtb, maybe it can work with it.

DTB: gxbb_p200_k2_pro.dtb
I can’t guarantee anything, because the SoC and tuner are different, but it’s worth a chance.
Edit:
Okay, wait a minute...
There are two different versions of this device. If your version has an S905D, the SoC and the tuner are the same as the KI Pro.
However, if there is really an S905D SoC in the device, the previously linked DTB will not work!
If this is the case, try it first without replacing the DTB.
But if that doesn't work, try it with this DTB: gxl_p231_2g_dvb.dtb
My S805 is a M8S. About your 9.02 builds for both M8S and M8S+, they do freeze quite often. Not sure yet when, looks also stopping/starting video related. For the M8S+ the 9.2 build does a better job.
For M8S-S805 (M8Q) devices, I will also be trying to make an image soon, because there is the same problem with the initramfs script.
If I remember correctly, we’ve already talked about this in another thread.
Then you wrote that there was a version that worked with wifi, just the power on did not work.
You should copy dtb.img from that version to the SD card and try it out.
I added a couple of fixes, the new version has been uploaded to GitHub, it is available on the releases page. (9.2.6-20210209)
I tried a few previous M8 audio configurations, but none of them changed the situation, only Analog and S/PDIF options are displayed in the ALSA list.
I tried passthrough on M8S+ with basic settings, and my TV recognized Dolby AC3 correctly, but I couldn't try DTS because unfortunately it is not supported on the LG OLED TV.
Another question: What kind of S805 device do you have? Maybe an MXQ-HD18Q (a.k.a. "all black" with 1GB of RAM) or an MXQ-m201d (512MB)?
Thanks, looks like it's fine now !
One more issue, when using the Retrospect add-on no video shows until I pause and play. Any ideas about this ?
Normal video playback from a smb share also works fine.
I'm missing the hdmi audio outputs, only spdif and analog is listed at the audio settings. So can't do audio pass through.
I'm trying to find a solution for online video stream problems (like pvr.iptvsimple), because in Kodi 18.5+ the extraction of stream info has been pretty reworked, and amcodec doesn't really like that. (It reports 0 fps, 0x0 resolution, and it cause other anomalies when starting a live stream.)
The "Default (analog)" seems to be equal to HDMI output, but I don't why. (The analog output has not worked since OpenELEC v6.)
I also use it with this settings and it works properly without passthrough, but I will check the passthrough mode with my TV.
I replaced the buggy initramfs script, so the freeze issue was solved.
The new version has been uploaded to GitHub.
Tomorrow I will try to find a better solution for this problem.
I reinstalled the 9.2 version. Installed the Dumpert addon and played 2 video's. The first one worked, the second one froze kodi.
It seems to have problems stopping video's and starting a new one.
Okay, I guess what the problem might be. After startup, try changing the resolution to 1080p to 720p, and try playing the video and then rewinding or stopping.
If the problem still exists, it will be different than what I'm thinking.
Okay, that's weird. My old version works, but the new one doesn't.
Can you send me a Kodi log?
Hi, I was just looking for an updated image for a M8S+.
I installed it and it boots up and works (network/wifi/bluetooth all is present), but when I try to play a video from whatever video addon I only get a spinner.
Looks very promising, hope you can fix the video playback !
It was a clean install or an update?
And which image did you use before?
