Looks good to me, though I'd feel slightly more confident in that we
haven't missed something if we had something a bit more complex using
it.
Unfortunately changing the dshow filter to use this will be a bit more
work (needs an option to select device by name instead of number,
a query function for that, and then the list_devices code must be
changed so it actually can return a list instead of only av_logging),
does someone know of another option, e.g. in some filter, that takes
specific strings, maybe even depending on the value of some other option?
