Thanks for the fast reply :)

Both decoders are currently at about the same development status with
comparable performance, reaching 50fps @ 4K. With libde265, the plugin depends
on a smaller library and is more modular.

We are concentrating on streaming applications and want to support additional
features that are not possible with a catch-all API, like dynamic switching
between sub-streams with different fps. Work on a complementing encoder is
currently starting.

We have ARM NEON support in the queue and are evaluating whether CUDA support
makes sense.

I see. I'm currently looking into providing a patch against -bad and will
attach that here when done.

I added that to our TODO-list for the next release of the library and will then
update the configure check accordingly.
