Original: Force keyframe-aligned GOPs across an ABR ladder with FFmpeg

Short summary

When ABR bitrate-switches misalign keyframes, players stutter at quality seams without showing rebuffering. Fix by forcing identical GOP cadence across all bitrates using FFmpeg's keyint, min-keyint, no-scenecut, and -force_key_frames flags. Verify alignment in CI with ffprobe diffs to prevent regressions on encoder upgrades.

  • •Keyframe misalignment causes micro-freezes during ABR quality switches despite zero measured rebuffering
  • •Force identical GOPs across all bitrate rungs: use keyint=60, min-keyint=60, no-scenecut, and -force_key_frames expressions
  • •Verify with ffprobe and add CI checks to block regressions on encoder upgrades
