Video encoding reduces massive raw video data by removing spatial and temporal redundancies, and Scalable Video Coding (SVC) extends traditional codecs with layered streams that adapt to varying bandwidth, resolution, and quality, offering benefits like single-pass encoding, packet loss resilience, and broad compatibility.
The article outlines how video container formats such as AVI, MOV, MP4, WMV, RM, FLV and MKV package encoded streams, then explains H.264 encoding fundamentals—including I‑, P‑, B‑frames, macroblocks, GOP structure, and NAL units like SPS and PPS that define parameters for efficient compression and transport.
The ARC Car Cloud Control platform now streams the vehicle’s screen using Android’s Virtual Display and a C++‑based H.264 hardware encoder, sending raw video over a TCP socket to a server that adaptively adjusts bitrate and frame rate, while the web client decodes the fragmented MP4 via MSE, dramatically lowering CPU usage and latency on low‑end head‑units.
This article introduces the fundamentals of video compression, analyzes the shortcomings of traditional iOS compression methods, explains H.264 profile and level concepts, examines device support, and provides a step‑by‑step custom iOS solution for controlling bitrate, resolution and frame rate.
This article details the architecture, encoding choices, network‑level optimizations, transmission model, measurement methods, and practical pitfalls involved in building a 1080p real‑time video streaming solution that consistently keeps end‑to‑end latency below 500 ms for interactive online education.
