public class FFMpegSegmenterTranscoder
extends CommandTranscoder

Segmenter transcoder that uses version 3 FFmpeg to create ts segments and its m3u8 play-list file. It overrides ffmpeg's `-segment_list` and `-segment_list_entry_prefix` arguments and uses filenames and paths provided by the streams application. Use parameter `httpPrefix` in createcaches.xml to set host and basefilepath. Default is: `http://localhost:8080/files/`. In createcaches.xml for example: <transcoder label="playlist-sd" mimetype="video/*" in="v4" id="v10"> <class name="org.mmbase.streams.transcoders.FFMpegSegmenterTranscoder"> <param name="httpPrefix">http://localhost:8080/files/</param> <param name="-c:v">libx264</param> <param name="-b:v">128k</param> <param name="format">m3u8</param> <param name="-flags">-global_header</param> <param name="-map">0</param> <param name="-f">ssegment</param> <param name="-segment_time">10</param> <param name="-segment_format">mpegts</param> </class> <loganalyzer name="org.mmbase.streams.transcoders.SegmenterAnalyzer" /> </transcoder>
