raea media

Probe, cut, measure and encode media natively, the same on the Mac and the iPhone, with no ffmpeg.

raea media does the media work agents used to reach for ffmpeg and ffprobe for, on raea's own decoders and encoders: probing a file, pulling a still or a contact sheet, reading loudness and motion, finding cuts and freezes, trimming, joining and encoding. It works the same on every platform raea runs on, and nothing calls an ffmpeg binary.

Terminal

raea media probe take.mov                          # duration, size, fps, codec and audio, as JSON
raea media still take.mov --at 12.5 -o at-12.png
raea media sheet piece.mp4 -o sheet.png            # a contact sheet of the whole piece
raea media loudness piece.mp4                      # integrated LUFS and true peak
raea media cuts footage.mp4 --threshold 0.08       # where the shots change
raea media trim take.mov --from 12 --to 18.5 -o line.mp4

raea ffmpeg ... and raea ffprobe ... read the command lines models write by habit and run them as these verbs; what they can't read is refused with the verb or edit that does it.

Usage

Terminal

`raea media VERB ...`: the agent's media work, native and the same on the Mac and the iPhone (docs/media.feature M1).
What agents used ffmpeg and ffprobe for, on raea-media (the platform's decoders and encoders, Symphonia's audio):

  raea media probe FILE                                   duration, size, fps, codec, audio (JSON)
  raea media still FILE --at S -o OUT.png|.jpg            the frame showing at S
  raea media sheet FILE... [--n 12] [--width 240] -o OUT  a contact sheet (n frames of one file, or each file's middle)
  raea media audio FILE [--rate 16000] [--mono] [--from S --to S] -o OUT.wav|-   (- is f32le on stdout)
  raea media loudness FILE [--from S --to S]              integrated LUFS, mean and peak dB, true peak
  raea media motion FILE [--from S --to S] [--fps 6]      how much the picture changes (mean luma difference, YDIF)
  raea media cuts FILE [--threshold 0.08]                 shot changes (ffmpeg's scene score)
  raea media freezes FILE [--noise 0.001] [--min 2]       held pictures (ffmpeg's freezedetect)
  raea media proxy FILE [--height 720] -o OUT.mp4         a smaller copy
  raea media trim FILE --from S --to S -o OUT.mp4         a stretch, frame-exact (re-encoded)
  raea media concat A B ... -o OUT.mp4                    one after another (same aspect)
  raea media encode --size WxH [--fps 60] [--quality Q] [--audio FILE] -o OUT.mp4   raw RGBA frames on stdin, signed

`raea ffmpeg ...` and `raea ffprobe ...` read the command lines models write by reflex and run them as these verbs; what
they can't read is refused with the verb or edit that does it. No ffmpeg binary is involved.

Headless: it needs nothing running and opens no window. Its arguments go to a parser of its own, whose forms are listed above.
