4k HEVC Playback Problem

[Guest asrequested]

What do you have in app bitrate set to?

[skawun 1]

The Emby addon for Kodi only has play and force trans code. No bitrate options like in the official app. I'm on the fence with outplaying the $150 Cad for premier. Tbh the reason I started trying Emby was be asue Plex needs to transpode HEVC h265 to h264.

We don't need to transcode it either if the device you're playing on supports hevc.

The mibox does according to their site. Could it be because my receiver isn't hdcp 2.2 compliant. It says it does 4k passthrough but I could never get my 4k Bell Fibe TV box to switch to 4k. It's a pioneer vsx1023

 

 

Edit:NVM I forgot I already tried it directly to my TV and it still stuttered

You say you have two MiBoxes. Do they both exhibit the same problem?

[skawun 1]

I have four actually lol. I've tried two at this particular location and they both exhibited the same problem. Another possibility is the fact that the path is, server, switch bell modem/router/wifi, streamer. The Homehub 3000 I believe has a separate wireless radio for wireless tv. Could I be maxing out its switching capabilities? I find that super hard to beleive as even these 4k streams from Bell TV are sub 50mbps I would think with all their compression

[Guest asrequested]

No, 50 Mb/s is trifling. Here's a silly question. Do you have the correct HDMI cables?

[skawun 1]

I can double check that but I had gone through the who hdmi thing when I was trying to get my receiver to pass my 4k signal from my Bell box. This is so frustrating

I've now tried using the native emby android app and for both TV setups I set max bitrate to 100mbps. For some reason the movie wont start and then after 10 seconds or so it will switch to transcoding to h264. Anyone know whats going on here? The MiBox supports 4k HEVC h265 so it should be direct playing.

 

Edit: I originally set the in-app max bitrate to 100mpbs and could not get direct play, would always revert to h264. I then reverted the global bitrate setting to auto and then tried playing the movie and setting the bitrate to 100mbps in the menu. It now direct streams. The "nerds" screen displays; Playback method: remux, Streaming Info: HEVC (direct) dolby 5.1, Transcode reason: Unsupported video.

 

Is this a bug of some sort maybe? I would think it should say unsupported audio as this tv has no sound system or receiver and is 2.0

 

Edit 2: Tried turning auto resolution on my Mibox instaed of 4k or 1080p 60hz and turned on downmix to 2.0 in the emby app settings. this caused everything to Direct Play. I then turned the global max bitrate to 100mpbs so I dont have to constantly change it from 21mbps to 100mbps and now all I get is a green screen. The nerd screen still shows direct play.

It might be your subtitles. Try turning them off. Also, choose dts or AC3.

Stream mapping:
  Stream #0:0 (hevc) -> overlay:main (graph 0)
  Stream #0:3 (pgssub) -> scale (graph 0)
  overlay (graph 0) -> Stream #0:0 (libx264)
  Stream #0:1 -> #0:1 (truehd (native) -> ac3 (native))

Your server is really struggling to burn in the psg subtitles, about 10fps.  As @ stated you will need to disable subtitles or get a more compatible subs (srt).  Almost every setup struggles with these subtitle types.

[Guest asrequested]

I think it'll play ok once you stop forcing it to remux because of the audio. 

[skawun 1]

Interesting. I'll try disabling them. What about the green screen that happens when setting global bitrate defaults to maximum?

Probably feeding the box a higher bitrate than it can handle.

[Guest asrequested]

Pretty sure it's ffmpeg.

[skawun 1]

Ebr, the screen turning all green only happens when I set the bitrate to 100 in the global settings. If I keep it to auto and switch it in the movie menu it works fine.

 

On my 2.0 system I set the app to downmox to2.0 and nerd window shows direct play truhd. On my 5.1 system I set down mixing to 2.0 off and the app is direct streaming and transcoding the auto to dolby 5.1.

When your system is limited to stereo input, then we down mix it in app.  So, it is direct playing that audio but that is not what is actually being sent to your system.  Make sense?

[skawun 1]

Definitely does. I figured that was what's happening.

 

On another note. The auto converting that's available for premiere. Will that work for keeping 1080p remux copy of my movies. I figure that for my 4k movies which I dont have alot of yet I should keep a 1080p version to direct play. Will this auto convert functionality work for that? Or would I be better of getting a separate 1080p file?

[Guest asrequested]

Forget transcoding 4k. Get a separate 1080, and add that.

[Sammy 790]

So it WAS a transcoding issue?

 

Seemed very similar to issues I've encountered with HVEC on some devices..

Ffmpeg seems to have trouble remuxing some 4k media.
