Configuration settings for AMD AMF HEVC encoder.

AMFHEVCEncoderSettings(VideoQuality)

Initializes a new instance of the VisioForge.Core.Types.X.VideoEncoders.AMFHEVCEncoderSettings class, optionally applying bitrate defaults derived from the supplied quality level.

public AMFHEVCEncoderSettings(VideoQuality quality = VideoQuality.Normal)

Parameters

quality VideoQuality

The video quality level that determines bitrate settings. Default is Normal.

Remarks

A previous revision shipped both a parameterless constructor and this one with a default parameter. C# overload resolution picked the parameterless form for new AMFHEVCEncoderSettings(), so the quality-based bitrate defaults were never applied. The parameterless overload has been removed to disambiguate.
