[PD] GEM: pushing gem output to v4l2loopback device

[Benjamin ~ b01]

hello,

you can grab what is happening in Gem window with pix_snap
and then use pix_record with a message like : [codec v4l2, file
/dev/video20, record 1<
if /dev/video20 is the virtual v4l2 device you want to use
attached a small exemple extracted from a bigger project, so it can't
work alone, adapt it to your needs
you can also send any Gem chain directly to pix_record and to a virtual
device without pix_snap
