A collection of HLS test streams.
A multivariant HLS playlist of Big Buck Bunny sourced from Mux's test-streams.mux.dev, with EXT-X-I-FRAME-STREAM-INF entries for trick-play (scrubbing/seek thumbnails).
Only the patched manifests are hosted here; all media segments (.ts) are still served by Mux via absolute URLs.
Playlist: https://pbs.github.io/test-streams/test-streams.mux.dev/x36xhzz/x36xhzz.m3u8
PBS-branded SMPTE-style color-bars test stream packaged as 4K multicodec HLS, captions, burned in ABR variant id overlay (e.g. 720 HEVC or 2160 AV1), and I-frame playlists for trick-play.
