[libav-devel] [PATCH] NVENC Input Surface Optimization

Hi, Please help review this nvenc patch for input surface optimization. This patch aims to reduce the number of input/output surfaces NVENC allocates per session. Previous default sets allocated surfaces to 32 (unless there is user specified param or lookahead involved). Having large number of

[libav-devel] [PATCH 7/8] hevcdec: fix cropping with new hwaccel API

[libav-devel] [PATCH 2/8] dxva: fix some warnings

Some existed since forever, some are new. The cast in get_surface() is silly, but unless we change the av_log function signature, or all callers of ff_dxva2_get_surface_index(), it's needed to remove the const warning. --- libavcodec/dxva2.c | 16 +++- 1 file changed, 7

[libav-devel] [PATCH 5/8] dxva: support DXGI_FORMAT_420_OPAQUE decoding

Some devices (some phones, apparently) will support only this opaque format. Of course this won't work with CLI, because copying data directly is not supported. Automatic frame allocation (setting AVCodecContext.hw_device_ctx) does not support this mode, even if it's the only supported mode. But

[libav-devel] [PATCH 1/8] dxva: add declarative profile checks

Make supported codec profiles part of each dxva_modes entry. Every DXVA2 mode is representative for a codec with a subset of supported profiles, so reflecting that in dxva_modes seems appropriate. In practice, this will more strictly check MPEG2 profiles, will stop relying on the surface format

[libav-devel] [PATCH 4/8] hwcontext_d3d11va: allocate staging texture lazily

Makes dealing with formats that can not be used for staging textures easier (DXGI_FORMAT_420_OPAQUE). It also saves memory if the staging texture is never needed, so this is a good thing. --- libavutil/hwcontext_d3d11va.c | 46 --- 1 file changed, 34
