I had issue with ffmpeg on my odroid xu4. Here is a workarround
- Install ffmpeg from the official repositories: Code
apt-get install ffmpeg libavcodec-extra-53 - remove the old ffmpeg binary: Code
mv /var/lib/emby/ffmpeg/20150917/ffmpeg /var/lib/emby/ffmpeg/20150917/ffmpeg.bak - link the installed binary to the location of emby ffmpeg: Code
ln -s $(which ffmpeg) /var/lib/emby/ffmpeg/20150917/ffmpeg
The transcode should work from now on. Its not perfect, but I guess better than nothing. I think the folder 20150917 is dependend on the individual installation.
