# ./videocmp_select.sh --scan-dir [DIR] [--recursive] [options]
|
||||
# (DIR defaults to "." if omitted)
|
||||
#
|
||||
# Examples of grouping by first token:
|
||||
# Becky_California.mp4, Becky_California.1.mp4 → group key "Becky"
|
||||
# Bianca_Golden.mp4, Bianca_Golden_Cut.mp4 → group key "Bianca"
|
||||
# Emylia.mp4, Emylia_Argan.mp4, Emylia_Wish.mp4 → group key "Emylia"
|
||||
# Logging:
|
||||
# By default, logs are written to: ~/log/videocmp_select.YYMMDD.log
|
||||
# Example: ~/log/videocmp_select.251014.log
|
||||
# Override with: --log-file /path/to/file.log
|
||||
#
|
||||
# Pipeline:
|
||||
# 1) Validate files (ffprobe fields + ffmpeg deep decode)
|
||||
# 2) Confirm same movie via snapshot SSIM @ --snapshot-time (default 12s)
|
||||
# 3) Optional: run external compare impl (simple/advanced) for logging
|
||||
# 4) Pick preferred: prefer --prefer-height (default 720), then longer duration, then larger file
|
||||
# 5) Act on loser: --action print|move|delete (with --dry-run)
|
||||
# Compare helpers (paths):
|
||||
# Defaults point to /home/urban/dev/wcx_script
|
||||
# --impl-simple PATH (default: /home/urban/dev/wcx_script/compare_simple.sh)
|
||||
# --impl-advanced PATH (default: /home/urban/dev/wcx_script/compare_advanced.sh)
|
||||
#
|
||||
# Common options:
|
||||
# --snapshot-time SEC (default: 12)
|
||||
# --snapshot-scale WxH (default: 320:-1)
|
||||
# --snapshot-ssim THRESH (default: 0.97)
|
||||
# --impl simple|advanced (default: simple) # logs only
|
||||
# --impl-simple PATH (default: ./compare_simple.sh)
|
||||
# --impl-advanced PATH (default: ./compare_advanced.sh)
|
||||
# --impl-optional (default) warn if impl missing
|
||||
# --impl-required error if chosen impl missing
|
||||
# --prefer-height N (default: 720)
|
||||
# --duration-eps SEC (default: 0.0)
|
||||
# --action print|move|delete (default: print)
|
||||
# --trash-dir PATH (default: $HOME/.video_trash)
|
||||
# --dry-run
|
||||
# --verbose
|
||||
#
|
||||
# Directory-scan options:
|
||||
# --scan-dir [DIR] Enable directory mode (DIR optional; default ".")
|
||||
# --recursive, -r Recurse into subfolders
|
||||
# (Note: delimiter-based grouping is deprecated; this script now groups by first underscore token.)
|
||||
# De-dup semantics (within each key/group):
|
||||
# • Keep **one** representative for each set of files that are the **same movie**.
|
||||
# • Two-stage "same movie":
|
||||
# 1) Fast path: identical signature (WxH, duration_ms, size) ⇒ same; no SSIM needed.
|
||||
# 2) Else: SSIM snapshot at --snapshot-time; SSIM ≥ --snapshot-ssim ⇒ same.
|
||||
# • After clustering, pick a single **best** (prefer height → duration → size) and drop the rest.
|
||||
#
|
||||
# Exit codes:
|
||||
# 0 success | 1 differ/broken | 2 usage | 3 missing dependency
