:)

libde265 and the openHEVC-based decoder in libavcodec are currently at
about the same development status with comparable performance, reaching
around 50fps @ 4K. With libde265, the applications or plugins depend on
a smaller library which 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.

Applications/plugins using libde265 are a GStreamer 0.10/1.0 plugin
[1], a HEVC/H.265 decoder plugin for VLC 2.x [2] [3] and DirectShow
filters for Windows [4].

Best regards,
