FFmpeg 2.6 released with some new features and improvements. The release has basic support for NVENC, The NVIDIA video encoder API for H.264 encoding and improvements to the VP9 decoder performance for x86 32-bit system and pre-SSE3 CPUs.

Many filters have been added and improved. Official posts say, “Regarding filters love, we improved and added many. We could talk about the 10-bit support in spp, but maybe it’s more important to mention the addition of color levels (yet another color handling filter), tblend (allowing you to for example run a diff between successive frames of a video stream), or the dcshift audio filter.”
