This is for output side, no?

We have problem on input side, where hw decoding does not cooperate with
filters ....

In theory you can use out-of-tree v4loopback module, and make ffmpeg
process video and *output* to v4loopback device, from where our (8 bpc)
input takes it ... May be using this as reason we even can request from v4l
devs to extend it for 10/12 bit and different subsample formats, if they
not already. But I suspect nowadays most work there done by paid
contractors, on request of larger companies. So hobby proj like ours will
have low standing ....

Isn't there sort of Command Execution built already into cingg? I mean
sending multiple assets as arguments to external command ... Ah, no, it for
RenderMux.sh/output ...

btw I think our script delete_brender_files fails to install for single
user .... something to quick fix!
