This example adds two #EXT-X-MEDIA tags with TYPE=CLOSED-CAPTIONS in See enabled demuxers and muxers. available in a metadata key named "variant_bitrate". FFmpeg is a free and open-source software project consisting of a suite of libraries and programs for handling video, audio, and other multimedia files and streams. Range is 10-100 Hz. audio and video frames are encoded before computing the CRC for each It creates a playlist file, and one or more segment files. For example the pattern foo-%*.jpeg will match all the For example, -adaptation_sets "id=0,seg_duration=2,frag_type=none,streams=0 id=1,seg_duration=10,frag_type=none,trick_id=0,streams=1".
