The original datasheet claimed H.264 encoding. The new datasheet reveals support for multi-stream compression . You can now encode one stream for KVM (low bandwidth) and another for local recording simultaneously. The register set for VE_OFFSET_CTRL has been expanded to handle two logical channels. aspeed ast2500 datasheet new
