Short random pauses while watching a movie.  This generally happens only when I'm playing a 4K movie.  If I play this same movie on Plex I have no issues. 

 

I really like the Emby Server and clients and was thinking I could replace my Plex server but I need to get these issues resolved.  I'm attaching the logs.

 

This happens on all clients (IOS, RoKu and LGTV)

Best guess would be Plex plays it at a lower bitrate then Emby.  Emby almost doubles the bitrate when converting h265 to h264, or uses the max bitrate set on the client. (transcoding at almost 140mb with a file bitrate of only 76mb )

 

Does the same happen if you lower/set the bitrate (video quality) on the client?

Yea can you try lowering the in app quality setting? Thanks.

Okay that worked on my IOS device.  The next issue is with my 4K TV also pausing  I'll do some testing and get the logs.

 

Also is a Geforce GTX 1070 good enough for transcoding a 4K stream?

 

Thanks

I'm attaching the logs from my playing of a 4K movies to my 4K TV.  The connection between them is a gigabit ethernet.  The direct stream works fine out of plex but I'm getting pauses from my Emby Server.

 

Thanks

It’s better. One thing I noticed was it does not pause when I change the audio to AC3. When I changed to the default audio of TrueHD is when the pause occurs. I checked the server and it was barely working either way. I did not test with Hardware Acceleration since I did not renew my subscription. I want to make sure I can flush out the bugs.

 

Thanks for the update on the server. It’s definitely better.

 

I’ll get you logs. I didn’t have time last night.

Here are the logs when TrueHD is selected and there are frequent pauses.  CPU is at ~4% and it says direct stream.

Here is the logs when it works with Dolby 5.1.  It says Direct Playing.  There are no pauses.

Another interesting thing.  If I force it to transcode by using PGS subtitles and with TrueHD it never pauses.  It uses 50% of the processor but runs without issue.

Hi @@jamespauly, this is the hardware detection log. Can you also supply the ffmpeg log? Thanks !

There is no ffmpeg log when running with TrueHD as the audio.
