Pretty much all of them!  We can ingest RTMP, SRT, WebRTC, HLS and RTSP for both our Ceecoder Transcoding as well as for our end-to-end Ultra Low Latency Delivery, however we do recommend SRT or WebRTC to achieve a lower latency.

Then we can transcode to (and deliver in) WebRTC, HLS, LL-HLS, DASH, CMAF, and MSS.

The video codecs we support are MP4, MKV, MP4/MKV over WebSockets, and VP8/9.

We support Opus, AAC, and AC-3 audio codecs.
