Good news today...
Compiling FFmpeg was a pain, and then DCPomatic took less than 30mn to build, compiling on 3 legs.
I've still got a complain at start: "failed to load configuration (XML file does not exist)"
I'm now going to settle a small test LAN with a master PC and the Pi.
First step: encoding the Bunny on master alone, then adding the Pi for a second run and see if it makes a difference.
A link to the reference asset used to benchmark DCP-o-matic would be appreciated.

Hi Fred,
That's a FFmpeg version that DCP-o-matic is not expecting. I think Debian
still package libav rather than FFmpeg. The best thing is probably to
fetch FFmpeg git:
git clone git://source.ffmpeg.org/ffmpeg.git
and then build it with something like
cd ffmpeg
./configure --enable-gpl --enable-postproc --enable-shared --disable-static
make
sudo make install
The .debs that I make for Debian/Ubuntu (sadly) statically link to FFmpeg
because of this situation.
Regards,
Carl
