10 bit encode not supported

These types of videos cannot be transcoded. I would recommend you watch them without transcoding.

[CaptWacky]

All of my 4K movies playback fine using Emby server with the Emby Fire tablet app. Hardware transcoding works fine with my server using about 20%~25% CPU.

I also re-installed Plex on my server. All of my 4K movies play fine using Plex server with the Plex Fire tablet app. Hardware transcoding works great with my server using about 10% CPU.

When I try to play 4K movies on the Channels server using the Channels Fire tablet app NONE of my 4K movies will play back. Server CPU utilization bounces from 99% to 50%.

It doesn't seem to be a problem with my hardware. I recently installed Channels DVR so I don't have any weird setups.

Is there something that I am doing wrong? I don't get it.

[tmm1]

When plex is transcoding, can you run this command in powershell and paste the output back:

Get-WmiObject Win32_Process | select commandline | Select-String -Pattern "Transcoder"

or this during emby transcoding:

Get-WmiObject Win32_Process | select commandline | Select-String -Pattern "ffmpeg"

v2025.01.27.1904

• FIXED: Transcoding of HDR with NVENC hardware encoder
• NEW: Experimental HEVC transcoding with NVENC hardware encoder

The latest pre-release should resolve this issue. Please let me know if you see any improvement.

[CaptWacky]

Doesn't seem to work.

Version 2025.01.27.2217

[/] Use HEVC for transcoding
Use HEVC (H.265) for transcoding instead of H.264 for streaming to client apps. Requires hardware that can handle encoding HEVC.

On the Amazon Fire 10 tablet it just shows a spinning circle as if waiting.

Does it work without HEVC enabled?

[CaptWacky]

with HEVC disabled it displays the following error message on the Fire Tablet after 30 seconds:

! Connection Lost

Please submit diagnostics from the DVR.

This is what it shows in the log:

Could you try the latest pre-release and see if that resolves your issue?

• IMPROVED: transcoder handling of non-HDR HEVC content on some hardware encoders

If not, please run this to make a sample of the file you're having problems with:

 ffmpeg -ss 00:05:00 -i 'Shrek.2001.2160p.4K.BluRay.x265.10bit.AAC5.1-[YTS.MX].mkv' -t 5 -c copy output.mkv

After updating to the latest Channels DVR I am getting the following error in Chrome browser:

[CaptWacky]

Well, on the plus side it does seem to be working now.

On the down side, all 4 cores of my server CPU go to almost 100%.

[CaptWacky]

Just want to add that when watching the same movie using Plex the CPU load stays fairly low.

[CaptWacky]

I have a dumb question.

When I look at ffmpeg in the channels-dvr folder it shows the following:

ffmpeg version 5.0.2 Copyright (c) 2000-2022 the FFmpeg developers

Is this the version that Channels DVR is using?

Why isn't Channels using a newer version like 7.1?

I have no idea if this would make a difference with transcoding but it might.

After updating to the latest Channels DVR I am getting the following error in Chrome browser:

Nothing changed that would impact that. You may have accidentally specified https://dvr-media-server.local to trigger that error.

@CaptWacky

On the down side, all 4 cores of my server CPU go to almost 100%.

Please run:

ps auxww | grep ffmpeg

and provide the output.

@CaptWacky

Why isn't Channels using a newer version like 7.1?

Because we update from time to time when we have the resources to do so.

@CaptWacky

I have no idea if this would make a difference with transcoding but it might.

It's likely it's an issue with how we are doing the transcoding, but I would not know for sure without more details.

If you could do this, it will help me run some tests on the content:
