Well at least now I have a tool for exposing that info.

BTW:
make show-filter-formats; and show-filter-formats scale 100:100
make: `show-filter-formats' is up to date.

I believe all the HW accelerated formats should be avoided, right?

Also how to feed a filter with video formats for which we cannot write

of ideas and asking is soo easy...
