Playback via WebInterface broken in Version 3.0.5782.0

[hotte 1]

Since the update of the Server from Version 3.0.5781.8 to 3.0.5782.0 i cannot play any movie (that are trasncoded) via the web interface.

 

Nobody else seems to have this problem, so it seems to be only a problem of my configuration. But i don't know how to fix.

 

In the transcoding log you can see that it is a issue of the parameter "force_key_frames" when calling ffmpeg.

The calling has changed from 3.0.5781.8 to 3.0.5782.0

Version 3.0.5781.?: -force_key_frames expr:gte(t,n_forced*5)
Version 3.0.5782.0: -force_key_frames "expr:gte(t,n_forced*3)"

 

I found an hint in the internet to include an Escape before the comma.

Hint: -force_key_frames "expr:gte(t\,n_forced*3)"

 

May this help?

Actually I think the issue might be that you've got avconv masquerading as ffmpeg. We have never done any testing with avconv and i have never seen this issue with ffmpeg

[hotte 1]

Yes, you are right.

I made a link from "/usr/bin/ffmpeg" to "/usr/bin/avconv". As far as i remember i had to do this because ffmpeg is not available in Ubuntu 14.04. It worked with Emby up to 3.0.5781.8.

 

Now i deleted the link and after a restart of Emby it uses "/var/lib/emby-server/ffmpeg/20150917/ffmpeg". This was the solution for my problem. I now have Version 3.0.5784.0 and the movies play again vie Web-Interface.

 

But other applications have no own ffmpeg and they need "/usr/bin/ffmpeg".

 

Is it possible to have "/usr/bin/ffmpeg" and tell emby to use his own "/var/lib/emby-server/ffmpeg/20150917/ffmpeg"?

[Luke 42085]

i think we might do that in the future

Yes I think that it will be a very good thing if we can choose if we want's to use emby's ffmpeg or the system ffmpeg or set a path to binary.

 

And by default set the emby's ffmpeg.

 

I've got lots of errors in wheezy when a package installs ffmpeg as a dependancy for example...
