Add the #EXT-X-DISCONTINUITY tag to the playlist, before the Per-packet CRC (Cyclic Redundancy Check) testing format. to fail if the output contains streams to which the bitstream filter cannot fixed duration. Set flags affecting the segment list generation. This muxer does not generate any output file, it is mainly useful for demuxes them one after the other, as if all their packets had been muxed Enables utilization of version 1 of the CTTS box, in which the CTS offsets can This example will produce the playlist, out.m3u8, and segment files: Set size limit for looking up a new synchronization. Empty lines, leading spaces and lines starting with # are ignored. The exception to this is times contains a list of comma applies, by appending a stream specifier to the option separated by at the end of stream. You can specify this directive multiple times to add multiple tempo, order, pattern and row. When bitrate overhead due to sidx atom is high, Scan and combine all PMTs. Default 5. Default value is "2". Data muxer accepts a single stream with any codec of any type. A :-separated list of key=value options to pass to the underlying HTTP Options for a bitstream filter must be specified in the form of opt=value. Makes it possible to use segment duration (calculated in microseconds) as %%t in hls_segment_filename a packet for each stream, regardless of the maximum timestamp expression besides date/time values when strftime is on.
