Unable to transcode any file

[michnmi 10]

Hi, 
I'm not exactly what I'm doing wrong. Nothing has changed that I know of. I'm running version Version 4.7.14.0

 

Any file I select to 'Convert', I now get the following message:

In the Conversions page I see that the item is queued: 

This now happens for any item, even ones that have already been transcoded by EMBY. 

What am I missing here? 

Can anyone help? 

 

Many thanks!

Hi there, please attach the complete emby server log. Thanks.

[michnmi 10]

Sure, thanks!

This is the server log:

OK so this is only an issue with the download and/or conversion features right? And is it only with audio files?

[michnmi 10]

The  issue is whenever I ask for a conversion. Downloads work properly. 
No, it's not audio files, it's mkv/mp4 files that have streams of video and audio. I haven't tried audio files to be honest. Basically, so far, it's all of the video files. This includes files that have been converted by EMBY.

Strange. Haven't seen this before. Can you try refreshing the metadata on those files and see if that helps?

[michnmi 10]

Thanks! 
I ran it. 
Again I get the same error. 
I've also turned on 'debug' in the logs, but the exception it throws hasn't changed. 

 

Here is the media info of the file:

Just as an addition here, whenever I transcode it on the fly (i.e. play it from a browser) the transcoding process starts:

It just doesn't start when I issue a convert command:

I have rebooted, restarted etc. 

I also have issued a refresh metadata of all files in the library which admittedly took a while. 
Still , nothing new. 

I tried stracing the command but that doesn't help with dll files. I could attach a debugger to find out why it's happening. 

 

Any other ideas? 

Thanks!
MM

Strange. Are you able to try the 4.8 beta server and see how that compares?

[michnmi 10]

I've installed 4.8 that was released yesterday and the issue has gone away. 
So weird. 
Thanks @Luke!
