Asset MPDs

SegmentTemplate variant $Number$ SegmentTimeline with $Time$ SegmentTimeline with $Number$

General timing ...

time-shift buffer depth (seconds) minimum update period (seconds). Default is the segment duration suggestedPresentationDelay (seconds) UTCTiming methods (comma-separated list of: direct, head, ntp, sntp, httpxsdate, httpxsdatems, httpiso, httpisoms, keep, none. "keep" keeps values from the VoD MPD and cannot be combined with other values. Default is httpiso) startNumber (default=0) -1 translates to no value in MPD (fallback to default = 1)

Multi-period ...

number periods per hour (1-60) period continuity signaling

Low latency...

availabilityTimeOffset (float in seconds or inf) chunk duration for low-latency (float in seconds) low-latency target (milliseconds)

MPD Patch...

Provides delta DASH MPDs at a PatchLocation

Set a positive TTL in seconds

SCTE-35...

SCTE-35 emsg frequency No SCTE-35 emsg boxes 1 event per minute, duration 20s, start at hh:mm:10 2 events per minute, duration 10s, start at hh:mm:10 and hh:mm:40 3 events per minute, duration 10s, start at hh:mm:10, hh:mm:36, hh:mm:46

Start and stop...

timeline start (and availabilityStartTime) relative to Epoch (in seconds) stop time for time-limited event (in seconds) timeline start (and availabilityStartTime) relative to now (in seconds). Normally negative value. stop time for time-limited event relative to now (in seconds)

Generate time subtitles...

languages for generated subtitles in stpp-format (comma-separated) languages for generated subtitles in wvtt-format (comma-separated) Cue duration of generated time subtitles in ms (<=1000)

Time subtitle region Region 0 (bottom) Region 1 (top)

Encryption and DRM

Encryption on-the-fly with keys via ECCP or commercial DRM systems. Pre-encrypted assets cannot be changed.

No DRM ECCP with cbcs encryption ECCP with cenc encryption EZDRM-provided DRM setup with one key CBCS encryption for livesim2 public test server EZDRM-provided DRM setup for WebRTC EZDRM-provided DRM setup with separate video and audio keys for livesim2 public test server

See /config for what commercial DRMs are configured.

Patterns of cyclic segment response codes

A square-bracket-surrounded list of comma-separated patterns, like

[{code:404,cycle:30,rsq:0,rep:video},{code:403,cycle:60,rsq:1}]

where:

code is an HTTP response code in the range 400-599
cycle is cycle in seconds
rsq is the relative sequence number in the cycle
rep is a comma-separated list of representation IDs to which the pattern applies (can be empty)

Traffic Patterns for one or more BaseURLs

Specify time interval for loss patterns for one or more BaseURLs with "up (u)", "down (d)", "slow (s)", or "hang (h)" states, like

u50d10,u10d50

d1,u1,u45s10h5

where:

u50d10,u10d50 is two pairs (two base URLS)
u50d10 means 50s up time and 10s downtime (60s cycle)
u10d50 means 10s up time and 50s downtime (60s cycle)
d1,u1,u45s10h5 means three base URLS where the first is always down, the second is always up, and the third is up 45s, slow 10s, and hanging 5s every minute

During a "down (d)" interval, all segment requests will result in a "404 Not Found" response.
During a "slow (s)" interval, all segment responses are delayed by 2s.
During a "hang (s)" interval, all segment responses hang for 10s before resulting in 503.
