# Rebuild the video tools' libraries in js/vendor/, the way the committed copies were made.
#
#   mediabunny-<version>/mediabunny.js  Mediabunny (MPL-2.0), trimmed to the parts the video tools use:
#                                       reading MP4, MOV, WebM, and MKV, writing MP4, conversion, and frame
#                                       extraction. The source map carries the original source of each file.
#                                       https://github.com/Vanilagy/mediabunny
#   gifenc-<version>/gifenc.js          gifenc (MIT), copied as published. https://github.com/mattdesl/gifenc
#
# Both are imported by js/tools/video.js only after a video arrives.
# Usage: scripts/vendor_video.sh [mediabunny version] [gifenc version]   (defaults 1.61.3 and 1.0.3)
# After changing a version, update the "video_libs" paths in scripts/tool_content.py.
