August 2026 Summaries

AV1 is an open, royalty-free video codec with a growing production ecosystem across browsers, devices, hardware, streaming platforms, and real-time communication services, making it the more practical deployment choice in 2026. Its successor, AV2, has a finalized specification and is designed to provide roughly 30% better compression efficiency while adding capabilities for scalable bitstreams, multi-stream and multi-view video, screen content, AR, VR, broadcasting, and conferencing, but its commercial encoders, hardware acceleration, players, and device support remain immature. Large deployments by companies such as Netflix, Meta, Google, and hardware manufacturers demonstrate AV1’s operational viability, although encoding costs, decoding coverage, and toolchain limitations still affect adoption. Organizations considering either codec should assess total system costs and real-world performance across representative content, target devices, networks, latency requirements, and playback behavior rather than relying solely on bitrate claims. AV2 is best treated as an experimental and strategic technology for future media workflows, while AV1 is generally better suited to current video-on-demand, streaming, and compatible live-delivery deployments with fallback codecs for unsupported clients.

CMSF and CMAF are not competing media formats but rather complementary technologies, with CMAF providing a standardized way to package segmented media and CMSF mapping these CMAF-packaged media into Media over QUIC (MOQ) workflows. CMAF is widely used for adaptive bitrate streaming and content protection in HTTP delivery, while CMSF extends these capabilities into a modern publish-and-subscribe architecture, making it attractive for media workflows that value CMAF compatibility, adaptive bitrate, and DRM. CMSF's strength lies in its ability to integrate existing CMAF structures into MOQ's streaming model, allowing for efficient adaptive bitrate switching and secure content delivery without discarding established media workflows. However, for applications that demand the lowest possible latency, such as drone operations, the lighter LOC container may be more suitable due to its reduced packaging overhead. The choice between CMSF, CMAF, and LOC depends on the specific needs of the application, balancing between comprehensive media capabilities and the need for minimal latency.
