A corrupt TIFF in production produced a wall of ffmpeg error output:
pyvips could not decode it, the generic ffmpeg fallback was tried, and
ffmpeg's TIFF decoder failed just the same — with banner, configuration
and stream-mapping spam included.
- Non-HEIC images are now decoded by pyvips only; a pyvips failure
raises a clean one-line ValueError ("cannot decode image: ...", a 422
like any other undecodable file) instead of invoking ffmpeg. The
ffmpeg path is kept for HEIC/HEIF, where pyvips genuinely falls short
(tile assembly, HDR metadata).
- ffmpeg runs with -hide_banner -loglevel error -nostats: error output
is still shown on failure, without the version/configuration/progress
noise. The -s insertion index no longer depends on fixed positions.
