Fields

name: *const c_char

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).

type_: AVMediaType

Type of codec implemented by the hardware accelerator.

See AVMEDIA_TYPE_xxx

id: AVCodecID

Codec implemented by the hardware accelerator.

See AV_CODEC_ID_xxx

pix_fmt: AVPixelFormat

Supported pixel format.

Only hardware accelerated formats are supported here.

capabilities: c_int

Hardware accelerated codec capabilities. see AV_HWACCEL_CODEC_CAP_*
