Types

encoding_t()

@type encoding_t() :: {:audio, String.t()} | {:video, String.t()}

Track configuration consists of the following fields:

id - identifies the track, will be serialized and attached to names of manifests, headers and segments
track_name - the name of the track, determines how manifest files will be named
content_type - either audio or video
header_extension - extension of the header file (for example .mp4 for CMAF)
segment_extension - extension of the segment files (for example .m4s for CMAF)
segment_duration - expected duration of segments.
partial_segment_duration - expected duration of each partial segment, nil if not partial segments are expected
header_naming_fun - a function that generates consequent header names for a given track
segment_naming_fun - a function that generates consequent segment names for a given track
target_window_duration - track manifest duration is kept above that time, while the oldest segments
```
      are removed whenever possible
```
persist? - determines whether the entire track contents should be available after the streaming finishes
mode - track's mode that dictates type of metadata inserted into playlist's manifest
encoding - keyword of strings representing encoding of content_type
resolution - resolution of video stream
max_framerate - maximal framerate of video stream
