Video transcoding turns one encoded stream into the versions your viewers can play. This guide covers transcoding vs encoding, how a live transcoder builds an aligned ABR ladder, a worked compute estimate for the ladder, and where the transcode can run.

How a live auction streaming app fits together, verbatim React code from VideoSDK's interactive live streaming quickstart, a rule for keeping bids server-authoritative, and a worked per-viewer cost example.

How advanced audio coding compresses sound, which AAC profile and bitrate suit a live stream, what an .aac or .m4a file holds, and why HLS and RTMP carry AAC while WebRTC uses Opus.

Buffering keeps a video playing through network dips until the buffer runs dry. This guide explains what the player is doing, why live streams rebuffer, and which encoder, CDN and player settings reduce stalls.

How HLS and MPEG-DASH differ on native playback, codecs, content protection and latency, where each one breaks, how one set of fMP4 segments can serve both, and which to use for a live streaming product.

Constant or variable bitrate? What each rate-control mode does inside the encoder, the peak limits HLS and YouTube set, capped VBR and two-pass VBR, and where the choice sits in a video SDK.

Frames per second is the count of images in each second of video, and the rate you choose decides how motion looks, how much bitrate you need and how long your GOP runs. Here are the standard rates, what Apple, YouTube and Amazon IVS ask for, and what variable frame rate does to an encoder.

A keyframe is the complete picture a decoder can start from, and the keyframe interval decides how fast a viewer can join, seek or switch quality. Here are the frame types, the GOP, the intervals Apple, YouTube, Amazon IVS and Cloudflare ask for, and what OBS auto really sets.
