+
+2017-xx-xx - xxxxxxx - lavc 58.4.0 - avcodec.h
+ DXVA2 and D3D11 hardware accelerated decoding now supports the new hwaccel API,
+ which can create the decoder context and allocate hardware frame automatically.
+ See AVCodecContext.hw_device_ctx and AVCodecContext.hw_frames_ctx. For D3D11,
+ the new AV_PIX_FMT_D3D11 pixfmt must be used with the new API.
+
+2017-xx-xx - xxxxxxx - lavu 56.2.0 - hwcontext.h
+ Add AV_HWDEVICE_TYPE_D3D11VA and AV_PIX_FMT_D3D11.

+ av_hwframe_ctx_create_derived() now takes some AV_HWFRAME_MAP_* combination
+ as its flags argument (which was previously unused).
+
+2017-04-xx - xxxxxxx - lavu 56.1.0 - spherical.h

+2017-03-xx - xxxxxxx - lavu 55.34.0 - hwcontext.h
+ Add av_hwdevice_ctx_create_derived().
+
+2017-02-10 - xxxxxxx - lavu 55.33.0 - spherical.h
+ Add AV_SPHERICAL_EQUIRECTANGULAR_TILE, av_spherical_tile_bounds(),
+ and projection-specific properties (bound_left, bound_top, bound_right,
+ bound_bottom, padding) to AVSphericalMapping.
+
+2017-xx-xx - xxxxxxx - lavc 57.34.0 - avcodec.h

+ (avcodec_send_packet/avcodec_receive_frame) always work with reference
+ counted frames.
