XtreamTranscoder™

ABR transcoding:
one feed, renditions for your audience.
Adaptive quality.

Real-time ABR transcoding with FFmpeg. Your original quality passes through without re-encoding and the transcoder adds the lower renditions: 1080p, 720p, 480p and 240p with aligned keyframes, so every viewer gets the quality their connection can sustain.

Real-time pipeline

From RTMP to multi-quality HLS in four steps

Your encoder sends a single feed. The transcoder creates the lower renditions and the server publishes all of them in one HLS manifest.

01

RTMP/SRT Ingest

OBS, vMix, Wirecast or any other encoder sends your feed over RTMP or SRT.

RTMP / SRT
02

Decode

FFmpeg decodes the feed to scale and encode the lower renditions.

03

Multi-Encode

The original quality passes through without re-encoding; 720p, 480p and 240p are created in H.264 with aligned keyframes.

04

HLS delivery

The server publishes one HLS manifest with every rendition for the player and the CDN.

Every viewer gets the right quality.

The player switches renditions according to each viewer’s connection: fewer stalls on mobile networks and top quality wherever the network allows it.

  • Original quality without re-encoding
  • 720p, 480p and 240p with aligned keyframes
  • One adaptive HLS manifest
How the ladder is built

Your original, untouched. Three more renditions.

The quality your encoder sends is published without re-encoding and the transcoder adds 720p, 480p and 240p. With a 1080p source, your audience gets four renditions in one HLS manifest.

Original

Original quality, no re-encoding

Your encoder’s feed reaches viewers exactly as you send it, with no quality loss.

720p, 480p and 240p

Lower renditions with aligned keyframes, so the player switches between them without jumps.

Live diagnostics

What reaches the server, in your panel.

Ingest diagnostics refresh every 10 s with your feed’s protocol, codecs, keyframe, fps and bitrate, so you can adjust the encoder before viewers notice.
