func RunTest

func RunTest(ctx context.Context, s *testing.State, cs ash.ConnSource, cr *chrome.Chrome, videoName string, decoderType DecoderType, gridSize int, measureRoughness bool)

RunTest measures a number of performance metrics while playing a video with or without hardware acceleration as per decoderType.

Types

type DecoderType

type DecoderType int

DecoderType represents the different video decoder types.

const (
	// Hardware means hardware-accelerated video decoding.
	Hardware DecoderType = iota
	// Software - Any software-based video decoder (e.g. ffmpeg, libvpx).
	Software
	// LibGAV1 is a subtype of the Software above, using an alternative library
	// to play AV1 video for experimentation purposes.
	// TODO(crbug.com/1047051): remove this flag when the experiment is over, and
	// turn DecoderType into a boolean to represent hardware or software decoding.
	LibGAV1
