Did you submit a dietpi-bugreport?

Extra details:

[MichaIng]

The reason is that ffmpeg just exists in Stretch and Jessie backports: https://packages.debian.org/stretch/ffmpeg
As backports are by default added to apt sources, but handled with low priorities, apt requests recognize it to install, but finds too low versions/non-existence of its dependencies inside the (stable) Jessie repo.

So you need to force that apt also pulls the dependencies from jessie-backports repo, or let's say DietPi need to ensure that, when offering backport packages.

Use: apt -t jessie-backports install ffmpeg

@Fourdee
Seems to be new/temporary that ffmpeg is not available in stable jessie repo?
https://github.com/Fourdee/DietPi/blob/master/dietpi/dietpi-software#L8127-L8132
We would need to add -t jessie-backports there for the moment at least.

€: Hmm, seems to be handled different in cases. On my VirtualBox Jessie image, the dependencies from jessie-backport got pullled automatically even without -t jessie-backports:

Confirmed on my XU4 👍

I'll apply the fix for XU4 Jessie for now. If we see this error on other devices/distros, we'll need to investigate a wider fix.

[Fourdee]

Tested on XU4, completed.

Does this also ensure that dependencies are pulled from backports? I remember that for pulling redis-server from stretch-backports on RPi, I needed to add it's dependency redis-tools also to the preferences package list.

Yep for redis-server, unsure for deps, 600 is a higher priority:

root@DietPi:~# apt-cache policy redis-server
redis-server:
  Installed: (none)

        500 http://ftp.debian.org/debian/ jessie/main armhf Packages
        500 http://security.debian.org/ jessie/updates/main armhf Packages

Before hand:

root@DietPi:~# apt-cache policy redis-server
redis-server:
  Installed: (none)
  Candidate: 2:2.8.17-1+deb8u5
  Version table:
     3:3.2.8-2~bpo8+1 0
        100 http://ftp.debian.org/debian/ jessie-backports/main armhf Packages
     2:2.8.17-1+deb8u5 0
        500 http://ftp.debian.org/debian/ jessie/main armhf Packages
        500 http://security.debian.org/ jessie/updates/main armhf Packages

So, to be consistent with default system-wide settings, its probably best I lower the Meveric repo, instead of increasing the backports.

@Fourdee
Ah, meveric repo explains different behaviours.

But I am wondering, as now I find all dependencies including right versions on meveric: http://fuzon.co.uk/meveric/dists/jessie/backports/binary-armhf/Packages

Maybe this was just a temporary issue during updating ffmpeg and all related dependency packages on repo?

Appears that way, hopefully. We'll soon find out and be able to resolve if other software titles are effected by this change.
