alloc_frame int function(AVCodecContext* avctx, AVFrame* frame) alloc_frame;: Allocate a custom buffer
capabilities int capabilities;: Hardware accelerated codec capabilities. see AV_HWACCEL_CODEC_CAP_*
caps_internal int caps_internal;: Internal hwaccel capabilities.
decode_mb void function(MpegEncContext* s) decode_mb;: Called for every Macroblock in a slice.
decode_params int function(AVCodecContext* avctx, int type, const(ubyte)* buf, uint buf_size) decode_params;: Callback for parameter data (SPS/PPS/VPS etc).
decode_slice int function(AVCodecContext* avctx, const(ubyte)* buf, uint buf_size) decode_slice;: Callback for each slice.
end_frame int function(AVCodecContext* avctx) end_frame;: Called at the end of each frame or field picture.
frame_params int function(AVCodecContext* avctx, AVBufferRef* hw_frames_ctx) frame_params;: Fill the given hw_frames context with current codec parameters. Called from get_format. Refer to avcodec_get_hw_frames_parameters() for details.
frame_priv_data_size int frame_priv_data_size;: Size of per-frame hardware accelerator private data.
id AVCodecID id;: Codec implemented by the hardware accelerator.
init int function(AVCodecContext* avctx) init;: Initialize the hwaccel private data.
name const(char)* name;: Name of the hardware accelerated codec. The name is globally unique among encoders and among decoders (but an encoder and a decoder can share the same name).
pix_fmt AVPixelFormat pix_fmt;: Supported pixel format.
priv_data_size int priv_data_size;: Size of the private data to allocate in AVCodecInternal.hwaccel_priv_data.
start_frame int function(AVCodecContext* avctx, const(ubyte)* buf, uint buf_size) start_frame;: Called at the beginning of each frame or field picture.
type AVMediaType type;: Type of codec implemented by the hardware accelerator.
uninit int function(AVCodecContext* avctx) uninit;: Uninitialize the hwaccel private data.
