kodi on ci20 creator

Hi there,

Does anyone knows what is going on with kodi dependencies on mipel ?

root@ci20:~# apt-cache policy libavcodec57
libavcodec57:
  Installed: (none)
  Candidate: 7:3.0.2-4~bpo8+1
  Version table:
     7:3.0.2-4~bpo8+1 0
        100 http://ftp.fr.debian.org/debian/ jessie-backports/main
mipsel Packages

root@ci20:~# apt-get install  -t jessie-backports libavcodec57

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 libavcodec57 : Depends: libx265-79 (>= 1.9) but it is not installable
E: Unable to correct problems, you have held broken packages.

However all I can find is:

root@ci20:~# apt-cache policy  libx265-87
libx265-87:
  Installed: 2.0-4~bpo8+1
  Candidate: 2.0-4~bpo8+1

Do I need to request a rebuild of libavcodec ?
