Streamtop

Terminal HLS, DASH, and IPTV stream monitor. Real-time health checks, wire probes, and production metrics from the command line.

Use it to debug CDN issues, validate encoder output, compare origin vs edge, run CI smoke tests on manifests, or watch production feeds with Prometheus and OpenTelemetry hooks.

WHEP HTTP endpoints are the supported path for WebRTC egress signaling probes. Legacy srt:// and rtmp:// URLs are rejected at startup.

HLS ( .m3u8 ): live, LL-HLS #EXT-X-PART / PRELOAD-HINT , part TTFB and Part RTF, #EXT-X-PROGRAM-DATE-TIME , media playlists

MPEG-DASH ( .mpd ): live and VOD, ServiceDescription latency, UTCTiming, ContentProtection / PSSH

IPTV / catalogs ( .m3u , .json , .yaml ): channel picker, search, playlist audit to JSON/CSV

SEI / HDR ( --probe-sei ): side metadata from H.264/H.265 elementary streams

Multi-CDN skew ( --multi-cdn URL1,URL2,... ): concurrent edge polling, live-edge seq/PDT skew matrix, ERR_CDN_SYNC_SKEW

Headless CI : stable streamtop.summary.v1 JSON contract (field version 5 ), --timeout , PASS/FAIL rules

Multi-stream agent ( --agent agent.example.toml ): fleet polling with aggregated /metrics

ABR ladder Bitrate, resolution, FPS, codecs. [wire] is from the bitstream; red = manifest vs wire mismatch

Compare mode: Space pause/resume, d detail, l log focus, c curl, h HAR, Tab switch pane. e also exports HAR in compare mode.
