Problem report container / format capabilities of tv #163

Closed bsod-haunted closed 9 months ago

bsod-haunted commented 1 year ago

Hi, here is the current setup:

There are issues with playing back 4K HDR videos encoded in h.265 that are in an MKV container. I reported this in a comment of issue 94.

As suggested in this comment in the same issue, I disabled "Allow video playback that requires transcoding". This "solved" the problem, as in the media is now correctly playing back on my tv. The dashboard shows the following:

Bevore the change / enabled transcoding

The media is being converted into a format that is compatible with the device that is playing the media. Framerate: 12fps 28.0 Mbps TS H264 AAC Reason for transcoding: The container is not supported

after the change / disabled transcoding

The video stream is compatible with the device, but has an incompatible audio format (DTS, Dolby TrueHD, etc.) or number of audio channels. The video stream will be repackaged losslessly on the fly before being sent to the device. Only the audio stream will be transcoded. Power consumed by direct streaming usually depends on the audio profile. Only the video stream is lossless.

This is the media Information

Video Title: 4K HEVC HDR Codec: HEVC Profile: Main 10 Level: 153 Resolution: 3840x1600 Aspect ratio: 2.40:1 Interlaced: No Framerate: 23.976025 Bitrate: 16426 kbps Bit depth: 10 bit Video range: HDR Video range type: HDR10 Color space: bt2020nc Color transfer: smpte2084 Color primaries: bt2020 Pixel format: yuv420p10le Ref frames: 1 Audio Title: Ger - DTS-HD MA - 5.1 - Default Language: ger Codec: DTS Profile: DTS-HD MA Layout: 5.1 Channels: 6 ch Bitrate: 2260 kbps Sample rate: 48000 Hz Bit depth: 16 bit Default: Yes Forced: No External: No

The behaviour is the same with every 4k HDR file I have.

If you need more information, i will do my best to provide it.

I can add to this issue my TV as well. I can't play the following formats:

Transcoding is atm not an option for my hardware as well sadly.

TV is a Samsung Q50 AAUXZG. After some investigation, it seems that my Oneplus 8 with Android 12 is also unable to play these files. This is odd because I am very sure that it should be able to handle these files. So maybe it is not a Tizen issue but a server/in a shared libray one?

Edit: I found the issue. My source MKV Files have a Bitrate of 37,x. The WAN Upload speed is not able to deliver that stable. Thus I need to fix the Bitrate to 20. Thus the need for transcoding.

Having similar issues here on my Samsung UN70NU6900FXZA

I haven't kept track of exactly what works and what doesn't, but I know that enabling subtitles for 4k MKV content seems to always encode, even if they're embedded subtitles or in a separate SRT file.

Will pay more attention to the specifics next time I'm in front of the TV.

It seems that this block strikes back (https://github.com/jellyfin/jellyfin/issues/5576#issuecomment-809645719). I see through Wireshark that my NU7400 (Tizen 4) requests HEVC stream, but cannot switch stream to HEVC and keeps playing the H264 fallback stream.

Removing mentioned block fixes issue.

Interesting. Kudos for busting out Wireshark to get the details.

I read through the issue and understand the need for backwards-compatibility, but I'd love to get this working without needing to run a dev version of JF indefinitely. Is this expected to be fixed in an upcoming version, or is the issue still stuck?

If stuck, is there anything we can report in the device profile that would indicate whether this block is necessary? Or perhaps we could add an advanced user setting to toggle this block of code?

Hi, it has been a while, but i can report that at least for my TV the issue is relsolved. I noticed that playback now does work fine with HDR 4K files, as long as there are no subtitels used in the file. I will open another issues for that though. Can anyone else confirm this, so this issues can be marked as resolved?

dmitrylyzo commented 1 year ago

In theory, HEVC HDR + TRUEHD/DTS with HEVC encoding enabled (server settings) causes unnecessary video transcoding (to SDR) as a fallback stream.
