Remix nPVR Workflow Components¶
Table of Contents
The archiver process uses Unified Capture (see Program Usage for further information) to create time based archive segments used by Remix.
Unified Origin - LIVE is used for Live playout, and for capturing / archiving.
Unified Origin - VOD plays out content for nPVR by taking the remixed MP4 created by Remix and playing out all streaming formats.
Based on a SMIL input, it compares the scheduled sources and produces a single remixed MP4 that is a representation of the playlist. Remix uses a set of heuristics to match tracks between separate input sources to enable the production of a seamless output presentation.
Below is an example using remix to generate a new clip in which the closed GOP is split across multiple sources.
unified_capture --remix does not insert additional keyframes at
archive segment boundaries, Unified Remix cannot use the initial and final
samples inside a GOP that is split over two segments unless both segments are
in the SMIL (restoring the original sequence).
Attempting to start a clip at the first sample of the first archive segment,
will result in seeking the nearest available keyframe instead.
