Pressing `T' in dired/dirvish on an audio file already transcribed
it; on a video file it bounced with "Not an audio file". Real
recordings ship as .mp4 / .mkv at least as often as raw .m4a, so
the one-key flow ended at the wrong place.
Pipeline now:
- audio path -> direct into `cj/--start-transcription-process'
(unchanged).
- video path -> async ffmpeg extracts the audio track to a temp
.mp3 under `temporary-file-directory' (libmp3lame, VBR q:a 4,
~165kbps -- right size for speech, accepted by every backend),
then transcribes that file with the temp marked for cleanup
after the transcription sentinel fires.
Surface changes:
- `cj/video-file-extensions' added to user-constants.el (mp4, mkv,
mov, webm, avi, m4v, wmv, flv, mpg, mpeg, 3gp, ogv).
- New predicates `cj/--video-file-p' / `cj/--media-file-p'.
- New `cj/--extract-audio-from-video' (async ffmpeg with success
callback; surfaces `cj/--notify' on failure; user-errors if
ffmpeg isn't on PATH).
- `cj/--start-transcription-process' gains optional `cleanup-file'.
Sentinel deletes it after the existing logic runs. Backwards
compatible -- the audio flow doesn't pass it.
- `cj/transcribe-audio' renamed to `cj/transcribe-media' (dispatcher
on audio vs video). `cj/transcribe-audio-at-point' renamed to
`cj/transcribe-media-at-point'. Both old names kept as
`defalias' so M-x history and any external references still work.
- `T' in dired-mode-map + dirvish-mode-map points at
`cj/transcribe-media-at-point'.
- Module commentary USAGE block updated.
15 new ERT tests in `tests/test-transcription-video.el' cover the
predicates (happy/boundary/error), ffmpeg invocation (correct args
+ missing-ffmpeg path), the dispatcher (audio direct, video via
extraction, non-media rejected), the aliases, and the T binding.
One existing test in `test-transcription-status-and-commands.el'
updated to stub the new delegate name.
Verified locally that ffmpeg is on PATH with libmp3lame, and that
the exact arg list my code uses produces a valid MP3 from a
synthetic test video.
