kajisho5/ffmpeg-skill v3.3.0

on GitHub

Automated release: version and notes generated from pull requests merged since 3.2.3.

Added

• source_carry: every result says what the output lost from its source. A tool that writes a
  media file compares what its first input carried besides the picture and the sound (subtitle
  tracks, chapters, a cover picture, surround channels, creation_time, the audio language tag, the
  start timecode) with the written file and reports source_carry: {kept, dropped}. A lost subtitle
  track, chapter list, cover picture or surround layout is also a source_items_dropped warning,
  unless the tool already says it through dropped_non_av_streams. Until now such a run was
  verified: true with no note (#401). The key appears only when the source had one of the items,
  never changes verified, and no tool writes a different file.

• npx ffmpeg-skill mcp starts the stdio MCP server (python3 mcp/server.py), the command
  the MCP Registry manifest (server.json, kept on the package version by the release bump)
  publishes. An OpenSSF Scorecard workflow runs weekly and on pushes to main (#369).

• tests/sweep.py runs one input through the 25 single-input tools and prints what each said
  (--baseline PLAIN keeps only the rows that differ from a plain clip's). With the
  sibling-sweep skill, the AGENTS.md rule and the PR template's "Siblings" section, a reported
  defect is now checked across the tools before it is fixed. Its first run, on the class behind
  #437, found #438.

• Codex and Gemini CLI plugin installs find the skill. codex plugin marketplace add kajisho5/ffmpeg-skill already installed the plugin, but Codex listed no skill for it: Codex
  0.167 and Gemini CLI 0.68 discover a plugin's skill only at skills/<name>/SKILL.md. The
  repository now carries skills/ffmpeg-skill/SKILL.md, generated from the root SKILL.md, a
  gemini-extension.json and a .cursor-plugin/plugin.json; the release bump moves their
  versions. Claude Code still counts one skill (#406).

• A plugin branch with only what a plugin install needs. Each release commits the npm
  tarball's contents plus the plugin manifest and the skills/ copy (2.6 MB, 88 files) to the
  plugin branch. Pointed at the repository root, a Claude Code or Codex plugin install copies all
  28 MB of it, tests and evals included. The marketplace entry moves to the branch once the first
  release has published it.

Fixed

• caption.py --srt --position put the text in the wrong place for every value but the bottom
  row (#436): top landed mid-left, center top-left, top-left top-right. The SRT burn hands its
  style to libass's force_style, which reads Alignment in the legacy SSA numbering, and it was
  given the v4+ numpad value. It now gets the legacy one (top 6, center 10, top-left 5,
  top-right 7); --text and --transcribe, which burn a generated ASS file, were right already.
• An odd-sized 4:2:0 JPEG (a phone screenshot) failed with "Invalid odd size" in insert.py
  and in every tool that converts a BT.601 source to BT.709 (#437): the colorspace filter, first
  in the graph, refuses an odd width or height. The frame is now padded to even for the conversion and cropped
  back to its own size after it, so no pixel is lost or resampled; an even-sized source runs the
  command it ran before.
• An odd-sized clip failed in caption.py and aborted stabilize.py (#438, found by sweeping
  the class behind #437). The runner's even-size retry put its scale at the head of the -vf
  chain, where a later filter could make the frame odd again; it now goes at the end, where the
  encoder reads it. stabilize.py scales an odd frame to even before both vid.stab passes
  (vid.stab asserts on one) and records odd_dimensions_scaled_even.
• Release versions: a squash commit whose subject does not end with "(#N)" is resolved to its PR
  by the merge commit's SHA (a failed lookup stops the release job instead of guessing). 3.2.3 shipped three features as a patch because the subject ended
  "(#433, carries #432 and #434)" and the feature label was never read.
• Say what the output lost from its source; fix --srt --position and odd-sized video; plugin branch (#435)
