Simulcast & Adaptive Bitrate (ABR)
Publish one stream with up to 4 simulcast layers; ppplayer's ABR picks a suitable quality automatically, and viewers can also switch quality levels manually with no black screen.
Seamless quality switching
pplayer runs ABR to pick a suitable quality and switches cleanly between layers with no black screen; viewers can also choose a quality level manually.
- Up to 4 simulcast layers (H264), up to 3 for HEVC
- Stepwise up/down to avoid oscillation
- No extra transcoding charge
HEVC / H264 multitrack
ppobs can publish H264 and HEVC as two independent streams. The player pulls HEVC-simulcast for roughly 30% less traffic when the browser supports it, and pulls H264-simulcast otherwise.
Built on standard WebRTC
Simulcast and ABR work with the standard WHEP player — no plugin, no proprietary player, no per-viewer re-encoding on the publisher side.
FAQ
How many simulcast layers are supported?
Up to 4 layers for H264 and up to 3 for HEVC.
Do viewers need to install anything?
No — playback uses the browser's native WebRTC (WHEP).
Is ABR billed separately?
Transcoding is free; you pay for downstream traffic and recording storage only.
