Member Function Documentation

apply_colorspace()

void va::va_t::apply_colorspace ( )

inlineoverridevirtual

Reimplemented from platf::avcodec_encode_device_t.

get_va_profile()

VAProfile va::va_t::get_va_profile ( AVCodecContext * ctx )

inline

Determines the matching VA profile for the codec configuration.

Parameters

ctx	The FFmpeg codec context.

Returns

The matching VA profile or VAProfileNone on failure.

init_codec_options()

void va::va_t::init_codec_options ( AVCodecContext * ctx, AVDictionary ** options )

inlineoverridevirtual

Provides a hook for allow platform-specific code to adjust codec options.

Note

Implementations may set or modify codec options prior to codec initialization.

Reimplemented from platf::avcodec_encode_device_t.

is_va_profile_supported()

bool va::va_t::is_va_profile_supported ( VAProfile profile )

inline

Determines if a given VA profile is supported.

Parameters

profile

The profile to match.

Returns

Boolean value indicating if the profile is supported.

select_va_entrypoint()

VAEntrypoint va::va_t::select_va_entrypoint ( VAProfile profile )

inline

Finds a supported VA entrypoint for the given VA profile.

Parameters

profile

The profile to match.

Returns

A valid encoding entrypoint or 0 on failure.

set_frame()

int va::va_t::set_frame ( AVFrame * frame, AVBufferRef * hw_frames_ctx )

inlineoverridevirtual

Set the frame to be encoded.

Note

Implementations must take ownership of 'frame'.

Reimplemented from platf::avcodec_encode_device_t.
