Intel / Hardware Transcoding

[jangle 1]

Good Afternoon,

 

I have an Intel based CPU/GPU which support H264 (Intel Quick Sync).

 

When I play a file H264 over a web browser using not transcoding it plays with no issue.

 

If I enable hardware acceleration transcoding it is unwatchable.

 

I have copied the latest FFMPEG to the folder and checked and still no answers.

 

I am struggling to work out how to resolve the issue.

 

 

Regards,

Jangle

I know they are going to say it so I will. Post more details on devices (versions and stuff) and log files. https://emby.media/community/index.php?/topic/790-how-to-report-a-problem/

Yup, more detail needed. When you say unwatchable, what exactly do you mean?

ThermoDust,  thank you I will gather further data.

Windows 10 Ent

Intel i7 4770R 3.2

8Gb 

1Tb SSD

Intel Iris Pro 5200

 

Installed - Version 3.2.35.1 Beta

 

FFMPEG 3.4

 

When I turn on Transcoding Hardware Acceleration and set it to Intel when a web browser plays a tv series from H264 format the picture being played is all grainy with boxes of pixels and nothing clear.

 

As soon as I turn of Hardware Acceleration it is working and the console confirms item is transcoding and all browsers play the episode with no issues.

 

I have used the same machine to convert files to H264 using the hardware encoding and it works with no issue.

 

I have upgraded the video drivers just in case.

 

I am not sure what I can do to drill down on this failure.

This is what it is without hardware transcoding.

Doofus I have uploaded a couple of pictures from Chrome when playing a OFAH episode one with hardware acceleration the other with it turned off.

Have you tried using the default ffmpeg?

[jangle 1]

I have downloaded the version from the Emby repository and recreated the ffmpeg folder under the server but I am still having the issue.

 

I removed the ffmpeg folder and still have the issue.

Which version did you get?

Also check your bitrate setting in the app, and make sure it's high enough.

[Guest asrequested]

If that doesn't work, then we need logs.

I downloaded this version - ffmpeg-20160410-win64.7z

[jangle 1]

Set to Auto comes up 4mbps.

[jangle 1]

Which log file?

[jangle 1]

Client 1Mbps - Transcoding 1000Kbps ts H254 mp3

 

Client 4mps - Direct play and still cloudy

This is an old build. Delete the folder(s) in this location, and restart the server

 

%AppData%\Roaming\Emby-Server\ffmpeg

 

Then use that location in the server for where ffmpeg is.

 

Also, from your transcode log, QuickSync isn't being used.

Emby is packaged with ffmpeg and ffprobe now in the system folder the ffmpeg folder is obsolete.

 

You can see from the log provided then proper ffmpeg is being used.

 

\AppData\Roaming\Emby-Server\system\ffmpeg.exe

 

 

***Unless one is replacing the ffmpeg in the system folder.

I know, but I don't know which he has, and I've seen Luke tell people to delete and restart. It's what I did, as mine was older and hadn't updated. I just figured I'd cover the bases.

Good Morning Doofus

 

Thank you for the update I have removed the folders.

 

Why is QuickSync not being used when the configuration has it enabled.

 

Is there anything I need to do to get it to be supported?

Good Morning Happy2Play

 

That makes sense now when I removed the ffmpeg folder and everything worked fine.

[jangle 1]

So how do I get QuickSync to work correctly?

[Tranquil 94]

Hard to say. QSV is still in an experimental state. Its not announced to be stable.
