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.
