A video codec compresses raw 720p video about 221 times so a call fits through a network. This guide compares H.264, VP8, VP9, and AV1 on compression, CPU cost, simulcast, and battery, separates codec from container and encoder, and shows how VideoSDK sets the codec and falls back to VP8.

A telehealth video platform is six layers, and the video call is one of them. This guide maps the architecture, shows what WebRTC does and does not give you, covers five telehealth UX patterns, summarizes the HIPAA controls, and prices 2,000 consults a month.

A video call API runs the signaling, media servers, and TURN relays behind a live call so your app only builds the interface. What it is, how a call flows through it, what VideoSDK, Daily, Agora, Twilio, and Amazon Chime charge per participant minute, and a ten-point checklist for choosing one.

Integrate a video conferencing API in six steps with VideoSDK: create a room, mint a scoped JWT on your server, join from the client, render participant streams, wire mute and screen share, then clean up.

A user on a 500 Mbps connection reports a laggy call and support tells them to upgrade. It does not help, because bandwidth was never the problem. Video quality is decided at three independent layers: network, compression, and packaging. Here is what each controls, and how to tell them apart.

A user on a 500 Mbps connection reports an unusable video call. Support tells them to upgrade. It does not help, because bandwidth was never the problem. Bandwidth vs latency explained properly: what each controls, why they respond to different fixes, and how to measure both in production.

H.264 vs H.265 is not a question of which is better. H.264 is mandatory in WebRTC and cheap to encode. H.265 halves the bitrate but needs newer hardware and costs more CPU. Here is what each one actually delivers, with bitrate numbers per resolution and a verdict per use case.

Most MKV vs MP4 comparisons get one thing wrong: they claim MKV has better quality. Containers do not compress anything, so they cannot. This covers what genuinely differs between the two, from browser support and HLS packaging to subtitle formats and truncation recovery.

This guide covers the architecture, working React code for host and viewer modes, multi streaming, and the cost crossover that decides your design.
