Maybe something like a query_params() callback defined on the device
in this case, since it will be device-specific.

I mean something like:
avdevice_query_params(devctx, &out, "list_devices", args?);

which fills out struct/pointer with the list of supported
devices. Something similar could be used for getting supported
resolutions/pixel formats/options depending on the physical device.
