Sorry, I know I'm not very knowledgeable about these things,
but I've been trying for two days to figure out how and if I can use the TC358743 module, my Pi5 (2712C1), and Libpisp.
I've compiled it and am trying to use convert.
First of all, I don't understand how to configure media-ctl.
I have to configure it as usual and have the output on /dev/video0
or do something like that?
Then with convert, do this?
Then I should have the output here? That is, with convert, I configure the stream and conversion?
In any case, none of these things work, of course. I would like to understand better...
maybe I should use /dev/video28 in convert?
