I don't see any error. Has the file
"/var/lib/motion/2018-01-24/2018-01-24T16-37-04_01_23.webm" been
created?

"pclose return: -1" seemed wrong to me. There is a webm file, but it's 0
bytes long...

Lets test your ffmpeg
Create a script "rawvideo.sh":
while [ true ]
do
mx=320;my=240;head -c "$((3*mx*my))" /dev/urandom
sleep 1
done
Then run a command:
./rawvideo.sh | ffmpeg -y -f rawvideo -pix_fmt yuv420p -video_size
320x240 -framerate 1 -i pipe:0 -vcodec libvpx test.webm
Let it run for some time and kill using CTRL+C
You should now get a test.webm file. Do you get it? If not - what
error does ffmpeg write to console?

Thanks a lot, you put me on the right track and I've finally figured out
the problem: the ffmpeg in /usr/bin (from Debian stretch) does have the
libvpx encoder. The more recent one in /usr/local/bin, built from
source, doesn't...
Now I'll just need to come up with a proper set of options to pass the
vpx encoder: right now the resulting files are much shorter, and sped
up, compared to their mp4 counterparts.
Anyway, thanks again for your help, it was invaluable :)
Cheers,
--Seb
