说明
MP4Box is a multimedia packager from the GPAC framework. It manipulates MP4/ISO base media files - adding, removing, and editing tracks without re-encoding. The tool handles muxing (combining audio, video, subtitles into one container), demuxing (extracting tracks), and file manipulation (splitting, concatenating, fragmenting). It supports numerous formats for import including H.264, H.265, AAC, MP3, SRT, and WebVTT. DASH (Dynamic Adaptive Streaming over HTTP) support creates segmented files for adaptive streaming. This fragments content into small chunks with a manifest file, enabling players to switch quality based on bandwidth. For streaming preparation, MP4Box can fragment files for HTTP progressive download, add hint tracks for RTSP streaming, and create initialization segments for live streaming workflows. Metadata editing covers MP4 tags, chapter markers, and track properties. The tool can also encrypt content with various DRM schemes.
