M3u8 Multivariant Input

Ingests an HLS multivariant (master) playlist via the native SDK m3u8MultiVariant node; video+audio renditions share one TimeDomain and are distinguished by positional renditionName (rendition_0, rendition_1, …). Subtitles still spawn per-language WebVTT inputs.

Options with an environment override can be set when Studio starts, without editing the workflow. <COMPONENT_ID> is this component’s id in your workflow, uppercased, with spaces and dashes replaced by underscores and other punctuation removed — a component named SRT Input reads SRT_INPUT_PORT. Renaming a component changes its id, and so changes these variable names.
