 That looks like the same problem that @JQZ* had a few posts back with Android write permissions.
Kodi doesn't ask for permission to write to your sdcard so it doesn't get it.
You are trying to write to /storage/emulated/0/backups
Did it work on the default special://temp ?

Test that Kodi has permissions to write to that directory in the kodi File Manager by creating or copying a file there.

You'll have to find one of the workarounds that works for you.

You can try Adopted Storage for the sdcard. That is probably what I am using on my Shield.

If you use a network hard drive I expect you have to turn on:
"pipe ffmpeg output through Kodi (for network folders)"
Set the "kodi recording folder" to something like a windows share that has write permissions.
Leave the "ffmpeg recordings folder" blank.  

Thanks for your help got it going now Last Question (for now) what exactly does the Delete ffmpeg function do?


Thanks again  

 Good.
What did you do, so I know what to tell people in the future?

"Delete ffmpeg" deletes the copy of the ffmpeg binary that is made in the Android /data/data folder.
It's there in case you overwrite the ffmpeg you pointed to with a new version.
The addon only tests if the path for the "ffmpeg exe" has changed before it will copy in a new ffmpeg binary.
This will force it.

The only reliable automatic way to do it is to copy the ffmpeg every time which would create a big delay before recording and is probably overkill. 

Ok so I altered the output file to the storage area on the firestick /storage/emulated/0/backups

I also used Delete ffmpeg (This might be a coincidence but worth noting)


Not got any external memory to work yet but will let you know the solution id I find one.



Thanks again
