# CCExtractor Docker Build
2+
#
3+
# Build variants via BUILD_TYPE argument:
4+
# - minimal: Basic CCExtractor without OCR
5+
# - ocr: CCExtractor with OCR support (default)
6+
# - hardsubx: CCExtractor with burned-in subtitle extraction (requires FFmpeg)
7+
#
8+
# Source options via USE_LOCAL_SOURCE argument:
9+
# - 0 (default): Clone from GitHub (standalone Dockerfile usage)
10+
# - 1: Use local source (when building from cloned repo)
11+
#

13+
#
14+
# # Standalone (just the Dockerfile, clones from GitHub):
15+
# docker build -t ccextractor docker/
16+
# docker build --build-arg BUILD_TYPE=hardsubx -t ccextractor docker/
17+
#
18+
# # From cloned repository (faster, uses local source):
19+
# docker build --build-arg USE_LOCAL_SOURCE=1 -f docker/Dockerfile -t ccextractor .
