OCR build fix: - linuxdeploy was failing with "Invalid magic bytes in file header" because it was passed the wrapper script instead of the actual binary - When OCR is enabled, ccextractor is renamed to ccextractor.bin and a wrapper script sets TESSDATA_PREFIX before executing the binary - Now correctly passes ccextractor.bin to linuxdeploy when it exists HardSubX build fix: - Add libavdevice-dev to FFmpeg dependencies in CI workflow - rusty_ffmpeg requires libavdevice which was missing 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

# CCExtractor AppImage Build Script
|
|
#
|
|
# Build variants via BUILD_TYPE environment variable:
|
|
# - minimal: Basic CCExtractor without OCR (smallest size)
|
|
# - ocr: CCExtractor with OCR support (default)
|
|
# - hardsubx: CCExtractor with burned-in subtitle extraction (requires FFmpeg)
|
|
#
|
|
# Usage:
|
|
# ./build_appimage.sh # Builds 'ocr' variant (default)
|
|
# BUILD_TYPE=minimal ./build_appimage.sh
|
|
# BUILD_TYPE=hardsubx ./build_appimage.sh
|
|
#
|
|
# Requirements:
|
|
# - CMake, GCC, pkg-config, Rust toolchain
|
|
# - For OCR: tesseract-ocr, libtesseract-dev, libleptonica-dev
|
|
# - For HardSubX: libavcodec-dev, libavformat-dev, libswscale-dev, etc.
|
|
# - wget for downloading linuxdeploy
