- has: searches what segmentation found, by the whole class name: has:dog, has:"dining table"
(has:table is a table, not a dining table). Plain words do not match segments.
- The catalog keeps each capture's segments (class, score, area) and its classes between newlines,
so a has: term is one contains per capture.
- Stats: "What is in the images", how many of the segmented images hold each class, each one a
has: search; shown even when nothing has been read by OCR. -stats logs it.
- Tests: has: (whole names, quoted names, case, combinations, plain words not matching).
- .library-folders in the library (src/app/library_folders.jai): each library folder's options,
starting with segment: true. Every folder starts off; unknown keys are kept when it is rewritten.
- The Segmentation window (Segments, above the grid): each folder's Segment checkbox, how many of
its images are segmented, and Erase per folder; a button to segment the folders set to segment.
- The segmentation scan (src/app/segment_ui.jai) runs on the OCR thread as its own task, with the
OCR scan's progress, pause and cancel: images only (never videos), not yet segmented, in folders
set to segment. The engine loads with the first scan (2.4 GB of GPU memory). Each image's segs and
mask are stored in one rewrite and its catalog entry loaded again.
- Importing into a folder set to segment segments the new images; the Import window's checkbox is
the folder's setting.
- -segment segments and exits; -erase segments, and -erase all now includes segments.
- The catalog reads each capture's segs (class list hash, segment count). The exit overlay names the
segmentation scan and model. segment_mcap_chunks moved into modules/Segment, shared with
segment-probe. The quoting helpers of Capture_File's text formats are public.
- Tests: .library-folders read and written back (quoted names, unknown keys, versions).
- Import brings in videos (MP4, MOV, MKV, WebM, AVI, WMV, MPEG, MTS/M2TS, FLV) on Windows, read with
FFmpeg: the file as it was in the original, a frame a tenth of the way in (at most 3 s), turned
the right way up, as the rendered image (what the grid, Capture window, OCR and labels see), and
import.json with Duration, FrameRate, VideoCodec, Rotation, PosterTime, Audio, and the camera,
date and location from the container. Elsewhere videos are skipped as "video (Windows only)".
- .mcap version 4: the original's size is a u64, so a video can be any size. Versions 1-3 still read.
mcap_read_without_original and mcap_write_streamed read and rewrite a file with its original left
on disk; mcap_store, mcap_erase, the import index and the import itself never hold a video in memory.
- Animated GIFs: Frames and Duration in import.json (gif_info).
- Grid: a play mark and duration on video thumbnails, GIF on animations. Capture window: what the
video is, and Play in the default player (written out to %TEMP%\mcap).
- modules/ffmpeg: FFmpeg 6.0 bindings and the five DLLs used (avformat, avcodec, avutil, swscale,
swresample), copied beside the executable by the build.
swscale converts into a buffer of its own allocator with padded rows: an exact-sized one let
its SIMD write past the end, crashing on frames of odd widths (1916, 1106 ...).
- image-probe shows videos and GIF frame counts; ocr-bench reads a video's frame.
- Tests: new video formats, display-matrix rotation, ISO 6709, video dates, GIF frames, and v4
serialize/parse, v3 compatibility, streamed writes, store/erase and extraction.
SnagitConverter's copy of Capture_File needs syncing to read version 4 files.
- Import window (and -import SOURCE DEST): every image under a folder (PNG, JPEG, HEIC, AVIF, WebP,
GIF, BMP, TIFF, camera RAW) becomes an .mcap holding the file as it was, a preview turned by its
EXIF orientation, and metadata.json and import.json Capture Text (date from EXIF, the file name or
its time; file name as title; camera as app). .snagx files become the same .mcap SnagitConverter
makes. Duplicates across the whole library are skipped by a hash index (.import-index); videos
and sidecars are skipped; source files are only read.
- modules/Image_Decode: stb_image, then WIC for everything else; EXIF; orientation; previews.
tools/image_probe.jai shows what it reads.
- modules/Snagx (and modules/jaison), copied from SnagitConverter.
- The library is a folder of folders: recursive scan, a folder filter, and a folder: search prefix.
- OCR, the viewer and ocr-bench decode any image format, turned the right way up.
- Rename D:\SnagitIndex to D:\McapIndex.
