AV1

AV1 编码非常非常慢 macOS Intel i7-8750H (12) @ 2.20GHz fps=1

  • Encode/AV1
  • libaom
    • Constant quality
    • Constrained quality
    • 2-pass average bitrate
    • 1-pass average bitrate
  • libsvtav1 - Intel x86-64 codec for AV1
    • Scalable Video Technology for AV1
    • 会比 libaom 快
  • librav1e - Xiph encoder for AV1
ffmpeg -h encoder=libaom-av1

# Constant quality
# CRF 0–63 - 0 lossless
ffmpeg -i input.mp4 -c:v libaom-av1 -crf 30 -b:v 0 av1_test.mkv

# libsvtav1
ffmpeg -i input.mp4 -c:v libsvtav1 -y test.mp4
