Emby update 4.1.0.26 issue

[Chris Able 0]

Hi,

 

I have 2 users that connect to my server throught the emby connect (one using a Roku and the other one using Firestick).

 

Since a week or so, their picture quality is getting blury and become not possible to watch movies or TV shows.

 

1- Could it be related to the last update?  Before a week or so, everythng was fine.

 

2- how could I get back to the previous version of Emby Server?

 

Thanks a lot

 

Chris

Hi, is it possible they just need to raise the quality setting in the app? If that's not it then can we please go over an example? Thanks !

[Chris Able 0]

Ok, I will see with them.  I will get back to you, thanks!

 Hi, just add the issue with my in house pc.  When I was watching a movie, the picture became like the attachment. then freeze.  

 

I'm continuing my investigation.

 

Thanks

You would need to post the server and ffmpeg logs.

Hi

here is the ffmpeg log.  Let me know if it tells you something, thank you

If you lower the in-app quality does the same thing happen as it is transcoding your 7+Mb file to 14+Mb to try and maintain the quality converting hevc to h264?

 

Does this happen if you disabled HWA?

[Chris Able 0]

I tried to lower the app quality, it does the same thing.   I fixed it at 1080HD 6 Mbps

 

It doesn't do that for all movies...

 

On another side, one person in my family with a firestick said that the picture frooze time to time (it was blury a couple days a go).

 

I'm not sure where/what is HWA?

Dashboard-Transcoding

 

Does this only happen on hevc files?

[Chris Able 0]

 I tried 10 movies on my roku and I was monitoring my dashboard at the same time.  When it was indicated in my dashboard direct playing, everything was fine.  Each time it was saying ''trancoding'' it was getting blurry.

 

Clearly, the problem is when there is a transcoding.  Maybe I don't know what I'm talking about but this is the only thing I found so far.

 

Let me know if you have any suggestions

 

Thanks!

I'm not sure what is HEVC files.

[Chris Able 0]

2 examples of movies that does that : 

 

Blow.2001.MULTi.VFF.1080p.mHD.x264.AC3-XSHD.mkv

Margin call.2011.MULTI.1080p.BluRay.DTS.HDMA.x265-FtLi.mkv

I'm not sure what is HEVC files.

 

HEVC/H265 is the video codec used during the creation of those files.

 

Most modern boxes are able to direct play this codec.  Older devices and browsers will require transcoding.

[Chris Able 0]

Even when I use my laptop and I watch those movies with issues, it still get blurry.  If I watch them with another player, like VLC, it is working fine.

 

 

What is very strange is that everythong was working fine for weeks and than suddenly this situation happen since +/- 1 / 2 week

 

 

I will continue digging

 

Thanks again for your help

As a test, can you try turning off hardware acceleration under server transcoding settings? Try setting it to no. Please let me know how that compares. thanks !

[Chris Able 0]

Hello!

 

Awesome!  It seems to work! :-)

I will continue testing it but is seems good.

 

So, I will maintain this parameter off for now one

 

Thank you for your time and for your help.  It is really apreciate

@@softworkz any thoughts?

[softworkz 5068]

From the ffmpeg log, I can see that the output bit-rate is way too low.

 

I'm not yet sure why this happens..

 

@@Chris Able - Do you have the latest AMD drivers installed? (from AMD - not the MS provided ones)

[Chris Able 0]

@softworkz : I just updated it (AMD drivers).  I will see in the following days if it make a difference.

 

Regarding the bit-rate, how can I increase this?

 

In attachement, you will find the ffmpeg log from today

 

Thanks

Chris

Using the quality setting in the video player.

[Happy2Play 9781]

Am I reading the log wrong?  It would appear the first log is set to 140Mb with a H265 stream at about 7.5Mb and it is transcoded to about 15Mb H264 and the second log show max 110Mb with a H265 stream at about 7.5Mb and it is transcoded to about 15Mb H264.  But the transcode never comes close to the 15Mb conversion.

 

The highest point in first log 5233.5kbits  Software decode/encode.

Stream mapping:
  Stream #0:1 (hevc) -> overlay:main (graph 0)
  Stream #0:3 (pgssub) -> scale (graph 0)
  scale (graph 0) -> Stream #0:0 (libx264)
  Stream #0:2 -> #0:1 (dts (dca) -> aac (native))

elapsed=00:00:07.21 frame= 308 fps= 43 q=28.0 size= 9047kB time=00:00:13.24 bitrate=5594.8kbits/s throttle=off speed=1.84x 
elapsed=00:00:07.73 frame= 328 fps= 42 q=28.0 size= 9468kB time=00:00:14.01 bitrate=5533.9kbits/s throttle=off speed=1.81x 
elapsed=00:00:08.25 frame= 350 fps= 42 q=28.0 size= 9754kB time=00:00:14.95 bitrate=5343.3kbits/s throttle=off speed=1.81x 
elapsed=00:00:08.75 frame= 371 fps= 42 q=28.0 size= 10140kB time=00:00:15.87 bitrate=5233.5kbits/s throttle=off speed=1.81x

No exit to see the average.

 

And the second log gradually climbs but in the 57.4kbit. Looks like software decode/hardware encode.

Stream mapping:
  Stream #0:1 -> #0:0 (hevc (native) -> h264 (h264_amf))
  Stream #0:2 -> #0:1 (dts (dca) -> mp3 (libmp3lame))

elapsed=00:00:37.25 frame= 2790 fps= 75 q=-0.0 Lsize=   41913kB time=01:39:44.80 bitrate=  57.4kbits/s throttle=off speed= 161x 

Is the first one dragging trying to burn in the psgsubs?

 

The second one looks this the encode is struggling on the hardware.
