Hi Martin and Rémi, I wanted to add a bit more context on the practical use case. There are several large and widely used Windows applications especially in enterprise and creator workflows that remain x64-only and rely heavily on FFmpeg at runtime. Examples include Feishu (Lark), Jianying / CapCut, and DingTalk, which are used at very large scale. Fully porting these applications to native ARM64 is a significant engineering effort and is taking considerable time. On Windows ARM devices, FFmpeg becomes a major performance bottleneck under x64 emulation. Using ARM64EC FFmpeg allows existing x64 applications to remain unchanged while enabling performance-critical media paths to run natively on ARM, providing a practical transition path for these applications. If there are any maintenance concerns, technical challenges, or areas where our help would be useful, we would be glad to support and contribute. Having ARM64EC builds of FFmpeg is important for enabling these real-world use cases.
